How to use a jigsaw correctly: the personal experience of the masters. Sawing with a manual jigsaw (step by step instructions) What to do when working with a jigsaw

An electric jigsaw is one of those tools that craftsmen buy first. In this sense, only a drill can compete with it. Why?

There are probably good reasons for this:

• The jigsaw is a very versatile tool. Saws a variety of materials, in any direction.
• The tool is simple, compact and inexpensive. Even a novice master with a modest budget can afford it.
• If you've worked primarily with hand tools, buying a jigsaw will dramatically increase your productivity and make your work a lot more enjoyable.

Choice of jigsaw

We talked in detail about how to choose a jigsaw, how they differ and what to look for. Let's briefly recap the main points.

The power of the jigsaw affects its performance. The more power, the thicker the workpieces it can handle and the faster the work.

Adjusting the speed of the electric motor and pumping the canvas is absolutely necessary if you work not only with softwood, but also with other materials.

For one-time simple work, any model of a jigsaw will do. But in the general case, for electric jigsaws, the statement “more expensive is better” is true.

Principles of correct work

After the jigsaw is bought, the master must learn how to use it. The jigsaw is a simple tool. But even a hammer - which is much easier - can be used in different ways.

There is a rule that knows no exceptions: there are no bad tools, there are tools that are misused.

In using a jigsaw, the master has "three degrees of freedom." The master must:

1. Choose the right equipment (nail file).
2. Set the optimal pumping amplitude and motor rotation speed.
3. Use the most appropriate working methods.

You can talk for a long time on each point, but we will try to highlight the main ones.

Tool selection

There are a great variety of saw blades produced and sold. They differ in the grade of steel from which they are made, the length and width of the blade, the shape and size of the tooth:

• The harder the material to be sawn, the finer the tooth on the selected file should be.
• For a curved cut, the file must be narrow. For cutting in a straight line - as wide as possible.
• The length is selected based on the thickness of the workpiece to be cut.

Especially many different files are produced for working with wood. For a quick cross cut, choose a file with large set teeth. A large step allows you to saw very quickly, but we give a lot of chips. For a clean cut, the tooth needs to be smaller.

Blades for cutting metal are very similar to a regular hacksaw blade for metal.

The saws must be sharp. For important and large work, store them in sufficient quantities.

Swap and speed

Pumping can significantly increase sawing speed. Usually it is turned on when you need to quickly cut a large wooden part in a straight line. In other cases, it does not help much and can even make work difficult or worsen the quality of the cut.

Figured sawing is performed with completely disabled paging. General recommendations cannot be given here. You need to try different modes. The most correct decision is to first practice on some scraps of material.

Inexperienced craftsmen tend to work with a jigsaw immediately at maximum speed. It is not right.

When cutting plastics, the file can become very hot at high speed and the plastic will begin to melt. Not all metals like high speeds.

Start at a low speed and increase it, carefully monitoring the result. If the quality of the cut deteriorates - the number of chips increases, the saw blade overheats, etc. - reduce the sawing speed.

working methods

As has been said many times, an electric jigsaw is a tool for many uses. However, the variety of situations is reduced to just three cases: straight sawing, curved cutting and hole cutting.

straight cut

This is the simplest case. Draw a line with a pencil and smoothly guide the jigsaw along it. The built-in laser pointer will be more than useful here. Sometimes a parallel stop, which is fixed on the frame of the jigsaw, can come in handy for such work.

The sawing speed can be maximum. Pumping will further increase the cutting speed.

To maintain a straight line, you have to “steer” with a jigsaw all the time. But even the most careful "tip" gives a mediocre result. In this type of work, the jigsaw loses to a circular saw both in terms of cut quality and speed.

If straightness and evenness of the cut is critical to you, use a circular saw instead of a jigsaw.

Curvilinear cut

Such cuts are the native element of electric jigsaws. They are "born" for this.

The main secret of success is not to rush. Mark carefully on the part. It is convenient to stick masking tape on the surface of the workpiece and draw lines with a pencil. Lead the jigsaw along the marking line, turning it with some lead. Bends with a small radius must be passed especially slowly so that for each stroke of the saw blade forward movement is minimal.

Hole cutting

This is one of those operations in which the jigsaw has no competitors. Typical examples: cut a hole in the countertop to install a hob or sink, make a hole in the wall of a cabinet for an outlet, and thousands of other similar cases.

To cut a hole in a part, you first need to drill one or more “starter” holes with a drill. A jigsaw file is placed in them and the cut begins and ends in this hole.

If you have to cut a very large window, it is more convenient to cut it in parts.

Sawing at an angle to the workpiece surface

All cuts described above can be made not only perpendicular to the surface, but also at an arbitrary angle up to 45 degrees to the plane of the part. The need for such cuts arises, for example, if you need to connect two parts "on a mustache."

• The working stroke of the jigsaw saw blade from the bottom up. On wooden blanks, because of this, chips appear on the surface facing the jigsaw. To avoid them, turn the part "face" down.
• Sawing parts from the “wrong side” is not always convenient. In this case, there will be less chips if you seal the cut line with masking tape.
• Another way to avoid chipping is to use files with a special "reverse tooth". However, with them, the return becomes very noticeable and additional physical effort is needed to hold the jigsaw.
• A jigsaw file is a very elastic element. Because of this, during the cut, it bends, which, in turn, leads to the removal of the cutting plane to the side. The thicker the sawn workpiece, the greater the withdrawal. To reduce it, use the sharpest files and feed the jigsaw forward as slowly as possible.
• Thin metal, thin plywood, hardboard can rattle a lot during operation. Such details need to be put on a sheet of 10-12 mm plywood and cut already this "sandwich".

Don't forget about safety

This is important, so it will not be superfluous to repeat the basic precautions.

1. Observe all normal requirements for working with electrical appliances.
2. Do not be lazy to maintain order in the workplace: do not keep extra items on hand, remove accumulated sawdust and trimmings more often, take care of good lighting.
3. If you don't enjoy pulling splinters out of your fingers and removing sawdust from your eyes, use personal protective equipment such as gloves, goggles, or a face shield.

Pay close attention to the organization of the workplace. And the work will go faster, and the fingers will be intact.

Jigsaw Care

Like any mechanism, a jigsaw requires care and maintenance. Especially if you use it often and intensively.

Practice shows that to increase the life of the jigsaw, you need to regularly lubricate the gearbox and rod. In addition, a lubricated tool runs quieter and smoother.

The jigsaw motor shaft rotates on ball bearings. They are durable and can work without additional lubrication for the entire life of the tool. But a jigsaw is not only an electric motor.

The rotation of the shaft is converted by a special mechanism into the reciprocating movement of the jigsaw rod. The pumping device adds to these up and down movements the longitudinal oscillations of the rod back and forth. All this complex mechanics is assembled on plain bearings. The loads from the working nozzle are transferred to them. No brainer that lubrication is a necessary component here.

For electric jigsaws, grease grades are used. They must be sufficiently refractory. During operation, the mechanism heats up from friction in the nodes and from the electrical windings of the motor located nearby. At the same time, ordinary lubricants are liquefied and squeezed out of the friction pairs.

We have selected a video for you, which shows the disassembly of the jigsaw for subsequent lubrication:

Conclusion

The specificity of using a jigsaw is connected precisely with its versatility. It is very easy to cut a part “without claims to quality”. Knowledge of the intricacies and special techniques of working with a jigsaw will allow the master to complete the work not only quickly, but also with high quality.

And, of course, experience matters. No theory can replace it. We repeat here the advice given above: practice on pieces of unnecessary material, try different attachments, change operating modes.

And tell us about your observations in the comments!

Lightweight, comfortable and easy to use - this is how you can characterize such a tool as an electric jigsaw. Many underestimate its capabilities and believe that with this tool you can cut only curved configuration details. On the one hand, this is its direct purpose, but if you look from the other side, you can understand that the possibilities of the jigsaw are much wider. Of course, this is not a multi-tool, but nevertheless, it can be used to perform a wide range of jobs. The main thing is to understand how to use it correctly, which will be discussed in this article. Together with the website, we will deal with the question of how to use a jigsaw - we will study all the features of working with this tool.

How to use a jigsaw: a few words about safety

Any modern tool, and especially an electric one, poses some danger to a person - in simple terms, rash actions can cause injuries and sometimes even very serious ones. In general, the danger of this tool should not be underestimated, and in the process, for your own good, it is better to follow some rules.

In principle, the list of what is better not to do when working with a jigsaw can be continued for a long time, but it is better not to do this, since almost all masters still ignore the safety rules, which, apparently, were made by a person who did not encounter practical using the tool. The main thing here is to have your head on your shoulders and not do anything that can cause injury to you. It’s better to talk about what can be done with an electric jigsaw, that is, let’s deal with the question of how to cut with an electric jigsaw?

How to work with a jigsaw: standard tool fixtures

Any, even the most seedy electric jigsaw, has at least three regular fixtures - a clip for replaceable cutting files, a swivel heel and a dust extractor. If we talk about professional ones, then there may be more standard devices for working with it. Let us consider these devices in more detail, since it is with them that work with a jigsaw is primarily associated.

Alternatively, some jigsaws can be equipped with laser or mechanical sights - a thing that is practically useless if it does not have manual adjustment. In addition, both household and professional tools of this type are equipped with a guide rail, which allows you to perform parallel, even cuts. The thing is thin, and you will have to adapt to it - even with this approach to business, the standard guide rail does not provide a completely perfectly even cut.

Work with a jigsaw: sharing the tricks of the masters

Any work with any instrument has its own subtleties and nuances - ignorance of them negates the possibility of a high-quality use of the instrument. We are talking about little tricks and various tricks that allow you to cut smoothly and, if necessary, with virtually no chips.

This is with regard to cutting techniques with an electric jigsaw. In addition to them, the master himself is fully responsible for the quality of sawing the material - as they say, he must have a sharp eye and a hard hand. Correct marking and precise control of the movement of the jigsaw cutting blade is the key to an accurate and high-quality cut.

How to use a jigsaw photo

And in conclusion of the topic of how to use a jigsaw, I will say a few words about such a device as a sawing speed regulator - not every tool is equipped with it, although the cutting speed is a very important point and it is chosen based on the type of material being processed and its thickness. It should be understood that too large “turns” lead to rapid wear of the file - during friction, it simply burns out, its teeth fail and, as a result, the jigsaw cuts crookedly or does not cut at all. In the same way, the feed force also affects the state of the jigsaw file - you do not need to put pressure on the jigsaw. He must move on his own - slowly, little by little. The fact is that excessive pressure leads to eversion of the file and, as a result, to an oblique and crooked cut.

A modern electric jigsaw is a high-tech tool that allows you to cut various building materials at high speed. Moreover, due to its design characteristics, the presented equipment can be used for both straight and curved (curly) cuts, as well as beveled cuts.

However, if the choice of a jigsaw is more related to the consumer criteria of the device, then the correct operation of the equipment allows you to extend its life and protect the consumer from injury and injury. The relevance of this topic is also related to the fact that not many users know how to use a jigsaw correctly.

Tool operating modes

It is no secret that the quality of the cut and the durability of the jigsaw largely depend on the correct choice of operating modes. And since most designs of modern electric jigsaws allow you to change the frequency of movement of the file and its transverse movement, it is these criteria that should be varied to achieve the most optimal result.

sawing wood

Due to the fact that the tree belongs to a soft material, it is advisable to cut wood at high speeds (hardwoods are an exception). At the same time, the use of the pendulum (transverse) stroke function in this case is justified only when working with thick wood materials. And although the most optimal mode of the pendulum mechanism can be determined empirically, nevertheless, power tool manufacturers are advised to adhere to the following recommendations:

• With a workpiece thickness of up to 30 mm, the pendulum mechanism is not used;
• With a workpiece thickness of 30 to 50 mm, the pendulum mechanism switches to position I;
• With a workpiece thickness of more than 50 mm, the pendulum mechanism switches to position II.

In general, it should be understood that the inclusion of the pendulum function, although they increase the productivity of work (cutting speed), at the same time significantly worsen the quality of the cut. In view of this, it is advisable not to use this mode when working with finishing materials such as laminate, parquet, furniture chipboard, etc.

Sawing metal

For many users, it may be a secret that you can cut metal products with a jigsaw. And all that is needed for this is to install the appropriate equipment and follow the basic recommendations.

So, when working with metal, the pendulum mechanism should be turned off, and the speed of the saw blade should vary from 30 to 40% of the maximum. At the same time, it is very important to provide the cutting site with an emulsion (water with machine oil) to extend the service life of the replaceable tool and reduce mechanical loads on the drive part of the electrical equipment. In addition, it should be understood that metal cutting with a jigsaw is a rather laborious and lengthy task. Therefore, during operation, it is necessary to ensure that the tool is periodically stopped to cool it down.

Cutting plastic materials

The electric jigsaw is used with great success for sawing plastic, plexiglass, textolite and similar components. And although the listed positions are not distinguished by high hardness, nevertheless, in order to avoid their deformations (chips, melting), they should be cut off at low speeds using saw blades with fine teeth.

Tile processing

If it is necessary to form curved cuts on tiles, a jigsaw can also become an impeccable assistant. However, to achieve optimal performance, the following recommendations should be followed:

• When processing, the maximum area of ​​\u200b\u200bthe tile should lie on the surface of the table;
• Be sure to use a specialized replacement tool;
• The frequency of the saw blade should be below average, without turning on the pendulum.

The choice of saw blades for an electric jigsaw

The use of files for other purposes can cause their deformation and cause the failure of the tool itself. Therefore, for various types of operations, only specialized equipment should be used.

So, for sawing soft wood-based building materials, it is justified to use files with a middle tooth pointing upwards. However, it should be understood that the existing set of teeth can cause damage to the front surface of the edges of the materials being sawn, which is why experts recommend cutting such building components as laminate, MDF, plastic from the back, for which the material is simply turned “face down” down.

If such a solution is not applicable, you can use reverse saws (teeth pointing down), however, in this case, the jigsaw will vibrate strongly, creating inconvenience for the performer.

When, with the help of an electric jigsaw, it is supposed to cut metal products, then specialized metal files should be used, which resemble ordinary blades in the shape of a tooth and are able to work in a long mode. Also, to get a clean cut, many experts recommend using saw blades for metal and for cutting soft finishing materials (laminate, parquet). However, in this case, you should be aware of the possible overheating of the equipment due to the increase in the duration of its operation.

In the case of working with ceramic materials, diamond-coated files should be used, and work should be performed only in exceptional cases (for example, for curved cuts).

In addition, regardless of the type of material being cut, when making curved cuts, preference should be given to less narrow nail files.

Jigsaw technology

Before using the jigsaw, you should perform preparatory work, namely: prepare the base, install a removable nail file (by tightening the clamps qualitatively) and connect the power supply.

If we talk about the features of working with an electric jigsaw, then the following points should be highlighted:

The cutting process should not be accompanied by excessive pressure on the jigsaw, pushing it forward. After all, not only can the workpiece be deformed in this case, the probability of saw blade breakage increases significantly, and the load on the tool drive also increases. That is, the task of the performer when using the tool is to maintain the desired direction, and the jigsaw will do the rest of the work itself.

In the case of straight cuts, it is advisable to use special clamps that will rest on the end edge of the material, thereby forming the same indent along the entire length of the cut. If you want to make round or oval cutouts, then the circle cutter, which functions on the principle of a compass, will be an ideal option for these works.

If it is necessary to cut thin sheet metal, experts recommend placing a sheet of plywood under the workpiece and cutting the materials together, which will minimize the deformation of the sheet.

Particular attention should be paid to safety (especially if the jigsaw turns over and works in stationary installation mode) and use personal protective equipment.

In order to reduce the load on the tool drive, it is recommended to change the nail files in a timely manner (as they become dull), as well as perform all routine maintenance (lubrication, cleaning debris, replacing brushes) in accordance with the manufacturer's recommendations.

In addition, the use of additional options that facilitate the work of the operator is justified. So to obtain an oblique cut, it is enough to set the support sole at a given angle. The laser pointer will help to determine the place of the intended cut, and the dust collector will ensure a “clean job”.

Connoisseurs of unusual design solutions are often delighted with pictures with beautiful rounded elements of furniture, stairs and structures that adorn the interior of houses. At first glance, such details are not available to ordinary users. But, having special ones and learning how to work with them, you can create interesting interior things that emphasize the uniqueness and individuality of the style of the room.

One of these hand tools is . This article describes how to work with a jigsaw for beginners, how to set it up, choose files and get the desired result.

Features of preparing a jigsaw for work

Blade selection. One of the main parameters of high-quality sawing is the right saw blade. For each material, the corresponding type of this cutting tool is provided:

• If you want to make a direct cut of wood, then you should choose a blade with medium (or large) teeth. Such a file can cut parquet, laminate, board. It is better to use files with a wide blade. On some models of saws, you can see a special badge - clean for wood - this is how manufacturers mark products for wood processing. They are easier to manage without spending excessive effort. The soft start function will help ensure an even cut - the engine accelerates gradually, without jerking;
• For metal, it is better to take a narrow saw with fine teeth. The thickness of the cut in metal is usually from 3 to 5 mm. The most durable alloys and stainless steel are easier to cut with a blade with the finest teeth. And for durable plastics and non-ferrous metals, you can choose a larger tooth size. Files for such operations are marked with the inscription - for metal;
• Ceramics or tiles are treated with a cloth without teeth. Instead, an abrasive composition is applied to the file, most often - diamond coating. The tool gently rounds the edges and makes a straight cut. It is not difficult to recognize the canvas. In addition to the absence of teeth, the side surface has a marker - special for ceramics;
• It is easiest to make curved sawing with a narrow and thin file with a fine tooth. Such a blade is not clamped during rotary operations, which contributes to accurate, error-free cutting. They consider it one of the best tools for curly cutting - even carved furniture is “too tough” for this jigsaw.

How to insert a file into a jigsaw. Correctly fixing the file is necessary not only for accurate cutting, but also to prevent injuries during work. Electric jigsaws are available with various types of saw blade attachments:

• Kolodochnoe. The most used type of clamp. The canvas is inserted into the block and clamped to the stop with two screws. The screws must be tightened carefully, not allowing the saw blade to skew. Replacing a blunt blade is just as simple - the screws are loosened, the file is pulled out, and a new one is inserted in its place.
• Screw. In such devices, the file is placed in a clamp and tightened with one screw. The canvas changes quickly and effortlessly. The main thing in installation is to check the angle of the inserted saw. Experts recommend not tightening the screw to the limit - this will lead to excessive vibration of the blade.
• Quick release. Does not apply to universal. This fastening is used only for a certain type of files. In addition, users have complaints about the reliability of fixing the file. The installation and replacement of the canvas is carried out as follows: the lever on the clamp is pulled, the blunt canvas is pulled out, a new one is inserted, it snaps into place, the lever returns to its place.

How to work with a jigsaw: features and rules

When cutting straight or sawing circular holes, it is important to choose the right mode correctly. Both the quality of cutting and the safety of the tool itself depend on this. Experienced craftsmen intuitively feel the operation of the tool, but there are basic recommendations for working with various materials.

Woodwork. It seems obvious to many craftsmen how to work with an electric jigsaw on wood. But there are nuances. For example, for soft woods, it is more expedient to cut at high speed. The denser and harder the wood, the slower the speed of the saw blade should be. The pendulum stroke of the 1st stage should be connected when working with workpieces more than 3 cm, and if the thickness of the board is more than 5 cm, then it is better to switch to the 2nd stage and higher. For example, a model in pendulum mode can handle a board up to 65 mm.

Interesting fact: many models of electric jigsaws, for example, are equipped with a pendulum motion function. This feature allows the file to move not only up and down, but also slightly to the sides. Multi-stage pendulum movement is used only for straight cuts, for dimensional workpieces or a large amount of cut, when productivity is needed, and the cleanliness of the cut can be neglected. The speed of sawing operations in the pendulum mode is greatly increased with a small loss in quality.

The cutting of metal is carried out in low-speed mode without the use of a pendulum mechanism. To improve the quality of the cut and reduce the load on the tool, it is recommended to apply a special composition to the cutting line - water mixed with machine oil. In addition, it is imperative to pause in work to cool the tool. Perfectly proved itself for such operations - you can connect a vacuum cleaner to it to collect sawdust.

The complexity of sawing plastic and similar materials, such as plexiglass or textolite, lies in the fragility of the processed materials. Despite the low hardness, they can be deformed, cracked or chipped. Therefore, it is better to cut them slowly, using a fine-toothed file.

Working with other materials. often used for cutting or rounding tiles and ceramic tiles. Its strength is low, so the processing speed must be set low, avoiding shock loads.

In any case, when trying to cut a material whose “behavior” is unknown, one must take into account its strength, thickness and hardness. To understand how best to set up a jigsaw for this material, you need to try out different modes on non-critical sections of the workpiece, and the operation of various files.

Here you can see the key parameters of jigsaws from leading companies:

Safety

You should not neglect the rules for working with such a tool - this can lead to injury. Therefore, it is important to know how to work with a jigsaw correctly and safely. A few tips for use:

• Be sure to wear safety goggles and a respirator;
• Do not lean on the jigsaw, achieving more significant pressure on the material;
• At any pause, the jigsaw should be turned off;
• Do not dismantle the protective screen;
• Securely fix the processed material;
• Turn off the tool if you see smoke, sparks or unusual noise.

If you are going to make repairs:

It takes a lot of practice to get used to working with a jigsaw and get even cuts. The main thing is not to forget about the main features of working with this power tool. So, tips for beginners on how to work with a jigsaw:

1. Before any operation, you should check the serviceability of the tool - only a well-functioning device can give an even and high-quality cut.
2. Blades must not be dull. This is checked visually - the sharp peaks of the teeth indicate the good condition of the cutting blade.
3. When cutting, the lower plane of the jigsaw must be entirely placed on the surface of the workpiece. This guarantees both a straight cut and vibration prevention.
4. Deformation of thin sheet material can be avoided by using a backing.
5. It is important to follow the manufacturer's instructions when choosing saw blades and cutting modes.

• Jigsaw Tips
• Conclusion on the topic

Any master should know how to work with a jigsaw. This is one of the most popular tools in the home workshop: it is convenient for them to cut wood, plywood, chipboard or fiberboard, metal sheet, various types of plastic. With a jigsaw, you can cut a part of almost any shape, if you approach the work correctly.

The jigsaw is an indispensable tool in construction and repair. With it, you can cut building materials or cut holes in them.

Like any household power tool, a jigsaw does not work automatically; it requires skills, experience, dexterity, and a thoughtful approach. It all starts with the choice of tools and consumables. This is not a trivial task, given that about a hundred models are sold only from well-known manufacturers.

The classification of electric jigsaws must begin with a general purpose. This is a professional, semi-professional or household tool. They differ significantly in technical characteristics, as well as a set of functions and capabilities. If the jigsaw is to be used often enough, be sure to pay attention to the following characteristics:

The internal device of the jigsaw.

1. Motor power. It determines the capabilities of the tool in working with materials of various thicknesses and complexity. The more powerful the motor, the faster the speed will be.
2. The presence of a pendulum mechanism. The pendulum mechanism should preferably be able to adjust the movement parameters. It allows you to work quickly when there is no need for great precision and cleanliness of the cut. The pendulum allows you to work effectively with many materials, especially softwoods, foam and plywood.
3. Speed ​​controller. They adjust the speed at which the saw will move up and down.
4. Possibility to adjust the inclination of the base plate. This function is needed in order to cut parts at different angles. There are usually several fixed tilt positions, such as 15°, 30°, 45°.
5. Laser guide. The beam in the path of the saw will help keep the line of the saw cut, resulting in a clean cut. Also, jigsaws are equipped with metal guides, but their capabilities are limited.
6. Availability of a quick-release chuck. Such a device will help to replace the saw in a matter of seconds (without effort and the use of an additional tool).
7. Power supply. The battery-operated tool is more mobile, but it is not enough for long work.
8. Saw set. It is usually sold separately, but is important for working with a certain material. Typically, the manufacturer indicates what material the saw is intended for cutting, what steel it is made of, what the direction and size of the teeth are.

These are just some of the main features. If we are talking about a professional tool, it is much more complicated, as it has the ability to fine-tune and a large set of functions.

Types of saw blades for electric jigsaw.

When preparing a jigsaw for use, you must follow the rules for working with an electric tool. It is necessary to inspect the device for damage, check the condition of the power cable and the connection to the power supply. Work without goggles and gloves is prohibited by safety regulations.

To work with different materials, it is necessary to select specially designed canvases for them and correctly configure the corresponding modes.

For example, for soft woods, you can use the pendulum mechanism and high sawing speed.

To cut laminated chipboard, to avoid chipping, the pendulum mechanism must be turned off, but the saw speed should be left high.

High-quality marking of the material, a thick, clearly visible line - a guarantee that exactly the figure that is needed will be cut out. It's good if the tool has a laser guide. It will help keep the right line. If not, you can navigate by the marks applied to the base plate.

Each type of plastic has its own characteristics of cutting, but there are general rules for all. These are small teeth on the saw, the pendulum mechanism turned off or set to a minimum and minimum speeds.

To understand how a jigsaw works at a high level, you need to gain some experience and skills. There are a lot of methods of working with this tool, all of them depend on the specific task, the capabilities of the device and the material being processed. But here are some general tips:

The main parts of the jigsaw.

1. The most commonly performed operation is the long straight cut. To cut straight, you need to choose a saw with a wide blade, it will help keep the line. In addition, many tools are equipped with a "soft start" function. If a straight line is especially important, this function must be enabled. The engine in this case is gaining momentum gradually, therefore, the beginning of the cut will be even. It doesn't take much effort to hold the tool when turned on. An electric jigsaw can cut a figure of almost any complexity. But this only applies to professional tools that can, for example, turn 360°. A household jigsaw will not take sharp turns.
2. An electric drill is an essential tool when it comes to working with a jigsaw. For example, to cut a circle or other shape inside the material, you must first drill a hole into which the saw will fit.
3. When working with a jigsaw, strong pressure is not only not useful, but even harmful. It will in no way speed up the process, except that it will lead to rapid wear of the saw and tool breakage. The speed of the device is regulated by the methods described above. You just need to guide the jigsaw with your hand, taking care to obtain the required cut configuration. In order not to constantly hold the start button with your finger, it can be blocked with a button specially designed for this. Power tools are designed to facilitate, not complicate the work of a person.
4. Electric jigsaws have a dust removal function. To implement this function, it is necessary to connect a vacuum cleaner to the nozzle. But it is worth remembering that this is by no means a simple household vacuum cleaner, but a special construction one. The fact is that in a household unit there is not enough high-quality filtration in order to retain fine dust. It can penetrate into the electric motor, which will lead to its damage.
5. To avoid vibration when cutting a thin sheet of metal, you can take plywood and use it as a substrate. In addition, the rattling will be less if you choose the right speed for the saw. It should be remembered that when cutting metal, frequent breaks must be taken so as not to spoil the saw and not to overheat the engine. With a low-powered jigsaw, it is better not to cut metal at all.
6. In order to cut any figure with high quality, it is necessary to securely fasten the material. Clamps, quick-clamping or conventional, are useful here. It is better to work on a carpentry workbench, and not on a stool. On an unstable piece of furniture, the material should be well fixed. Most likely, this will not be possible without outside help.

In order to avoid chipping on the bottom or top side, for example, laminated chipboard, it is necessary to choose the right saw or turn the material with the right side.

But, if there is a need to get a chip-free cut on both sides, you can use a small piece of fiberboard. It must be put on top of the chipboard and start sawing.

The chip will remain on the fiberboard, the plate will be with a clean cut.

Using a blunt saw is not recommended for several reasons. First, the quality of the cut will be low. Secondly, a blunt saw will only increase the load on the jigsaw motor, which will lead to premature wear. It is better to immediately replace the saw after it began to cut worse.

Instructions for the care of the jigsaw must be included in the kit.

Do not ignore the safety regulations.

How to cut with a jigsaw. A jigsaw is, in fact, an electrically powered saw

More recently, our fathers and grandfathers used hand tools. Nobody even dreamed of an electric planer, an electric drill, an electric jigsaw. Hand tools are now a thing of the past. In its place come electrical counterparts. One of them is an electric jigsaw.

When buying a jigsaw, you get a universal tool. They can cut wood, iron, plastic and even tiles. It is only necessary to purchase files that are designed to work with various materials.

You will need
Goggles, gloves, machine oil.

Instructions about how to cut with a jigsaw:

1. The movement of the jigsaw blade may cause your workpiece to vibrate, so secure the material well before starting work. It is not recommended to cut wood along the grain with a jigsaw, because it will be very difficult for you to make an even cut. A circular saw is best suited for such purposes. If there is no such saw at hand, then be sure to use a parallel stop. At one end it is attached to the jigsaw, and at the other end it rests on the edge of the workpiece. So you can achieve a more even cut.2. If you need to saw through a circle inside the workpiece, then first drill a hole in the circle. Insert a jigsaw into the drilled hole and start moving towards the markings that you applied on the workpiece. If you need to cut a square or rectangular hole, don't try to cut square corners right away. First, smoothly bend around them, leaving the markup of the next side. When you cut the desired hole, you can easily correct the corners of your workpiece on both sides.
3. When working with a jigsaw, do not press hard on it. This can cause the blade to heat up and break. Do not use one file for a very long time, as it becomes dull with prolonged use. A blunt file can cause score marks on the edges of the material. When cutting hard materials, lubricate the blade with a few drops of machine oil. This will facilitate the work of the jigsaw and extend the life of the file.

4. When working at low speeds, give the jigsaw a break. There is a risk of engine overheating during this operation.
Don't forget to follow safety precautions. Work with safety goggles and gloves. After work, clean and lubricate the tool.

How to cut with a jigsaw correctly

The tool allows you to cut almost any material, namely, metal, wood, plastic, ceramics, and even stone. The cutting blade is capable of plunging, straight, curved cuts, as well as cutting circles. In the article, we will analyze how to cut with an electric jigsaw correctly to ensure that the cut matches the given markup.

The electric jigsaw can have a normal and pendulum stroke. During normal travel, the blade moves vertically, cutting through the material as it moves up. The tool, which has a pendulum stroke, additionally, when moving up, feeds the web forward.

At the same time, a higher working speed is achieved, as well as blade wear is reduced due to the deflection of the saw blade in the opposite direction when moving down.

The question reasonably arises about how to cut with an electric jigsaw with a pendulum stroke? The work is done in exactly the same way, but it is taken into account that with the maximum deflection of the file, it is best to cut soft wood and plastic.

When cutting chipboard, MDF, soft metal, thick wood, it is necessary to reduce the amplitude of the movement of the blade. This mode is not recommended to be used at all when working with steel sheets.

How to saw with a jigsaw along a curve

To cut a round hole, you need to drill an initial hole in the workpiece, into which the file is then inserted. After that, a cut is made according to the mark.

If a rectangular or square hole is to be sawn, then the cutting is made in a straight line to each of the edges, after which the canvas is slightly retracted, and is carried out along a curved line to the next side. So all four sides are cut.

After removing the sawn area, the remaining triangular parts are sawn out.

If it is not possible to make an initial hole in the workpiece, then plunge sawing can be used. To do this, the working jigsaw is tilted forward until the saw blade reaches the workpiece. Gradually, the file will make a through hole in the workpiece. The cutting point of the saw blade should be located in the cutting part of the workpiece.

The jigsaw is able to cut bevels, as a result of which the edge of the resulting product will have an even cut in some direction. For such a cut, it is necessary to change the installation angle of the jigsaw ski, and then cut.

How to cut straight with a jigsaw

How to cut straight with a jigsaw? This is the easiest. It is enough to fix the guide on the jigsaw, and then lead it over the edge of the workpiece. Now the movement of the file will occur exactly, relative to the edge. If the edge of the workpiece is curved, sawing is carried out according to the preliminary markings applied to the workpiece.

If a thin wooden sheet is sawn, then there is a high probability of chips on the front of the product, since the saw cuts the material when moving up. To prevent this phenomenon, it is recommended to place the workpiece face down or use anti-splinter liners.

Without a share of irony, we can say that a jigsaw is an indispensable assistant in the house of any owner. He will cope with a wide variety of tasks - he will cut out an oval, a wave and other intricate shapes from almost any material: be it wood, plastic, stone, steel or even ceramic tiles.

Functionality The jigsaw is used for cutting various types of wood, fiberboard, chipboard, non-ferrous metals and steel, plastic, ceramic tiles, glass, and some types of stone. With this tool you can make straight, curved or plunge cuts.

Moreover, the jigsaw is the most skillful tool for cutting circles of different diameters, ovals, waves and other complex shapes. Cutting a hole in the countertop, for example, under the sink in the kitchen, or making original platbands for the dacha with your own hands is not a problem! Everyone can feel like a jack-of-all-trades thanks to modern power tools.

If we talk about its professional use, then I must say: this tool is necessary in the work of a construction joiner and a joiner with an artistic bias, a furniture carpenter, a wood craftsman, a drywall worker, as well as those who are involved in the manufacture of the most complex parts with the highest accuracy.

Types and characteristics Let's start with the fact that, like all power tools, jigsaws are professional and household. The former are distinguished by a larger electric motor power (from 580 W to 720 W), and the latter have sufficient potential for robots at home (with power from 350 W).

For comparison: "home" electric jigsaws saw wood up to 50 mm thick, metal - up to 23 mm; but with the help of the "pro" you can achieve a cutting depth in wood - from 85 to 135 mm, in metal - 10-20 mm.

The higher the power of the tool, the greater the thickness of the material it will cope with. But this only means that “household” indicators are quite enough to work at home. Cut a hole with a radius of at least 15 mm with all electric jigsaws "too tough".

In addition, when choosing a "home assistant", pay attention to its characteristics - if the lowest frequency of file strokes is below 1000 per minute, then it will not "take" plastic. Electric jigsaws are also subdivided according to the type of body: with a handle with a bracket and a mushroom-shaped handle. It is rather difficult to give an advantage to one of these types - each is convenient in its own way.

Therefore, manufacturers often meet the needs of the consumer and produce the same model (according to technical specifications) in different versions. You can also classify jigsaws according to the principle of fastening the saw: for a saw blade with a cross-shaped shank, with a smooth shank and with a shank with a hole.

The first two types are most widespread, as they are suitable for most models of electric jigsaws. Design features First of all, let's pay attention to several nuances of the tool design. Each electric jigsaw is equipped with a support sole, which rests on the part to be sawn, thereby ensuring the accuracy of work.

To make oblique cuts, the sole rotates within ±450. There are also models with the ability to fix the jigsaw only at an angle of 0/15/30/450. The cutting element of the electric jigsaw is a file. It can be made of different materials, have a different shape, size, method of sharpening and breeding teeth.

For cutting materials with a low density, saws with a length of 75, 85 or 100 mm are suitable. The size of the saw pitch also matters: for a tree, a pitch from 2.5 to 4 mm is optimal; for metal - 12 mm. To work with materials such as glass and ceramics, saw blades (the same saws) with an abrasive coating are designed. Non-ferrous metals are cut using saws with a wavy cutting edge.

Principle of operation Let's face it, the principle of operation of a jigsaw is quite simple. The file with the help of a screw is securely fastened in the slider (moreover, it is inserted in one movement, and it is even easier to remove it by pressing a button) and reciprocates with an adjustable (which is important!) frequency up to 3000 strokes.

All modern jigsaws have a multi-stage pendulum stroke, which ensures the deflection of the saw blade when moving down. Thanks to this feature, the saw blade cuts only when moving upwards, thereby extending its service life and increasing productivity. During operation, the jigsaw is held with one hand, so the weight of the tool matters.

The lightest model weighs 1.6 kg, and the heaviest weighs up to 2.8 kg. But it should be remembered: the larger the mass of the jigsaw, the more powerful it is. Equally important is the presence of control electronics in electric jigsaws, which ensures that the frequency of strokes is set under different loads and the processing of various materials.

As a result, even at the lowest stroke frequency, the tool works at full power. Expensive modifications of electric jigsaws are equipped with the so-called constant electronics, which automatically maintains the selected number of double strokes per minute, regardless of the load on the working tool. Some modern models of jigsaws have a sawdust removal system.

They are blown away by the air flow supplied by the motor cooling fan. This ensures convenience in work, since the sawdust does not cover the previously applied markings on the material. And so that the operator does not breathe dust and the workplace does not become clogged, a special device for connecting a vacuum cleaner can be used.

For ease of use during a long process, in order not to keep the start button constantly pressed, almost all models of jigsaws are equipped with a switch lock button. To protect the operator, the tool is equipped with transparent safety guards. There are also models with a special touch protection mechanism.

Additional devices In principle, a jigsaw does not require special conditions for efficient operation - it can work quite “independently”. But still there are some devices that increase its "working capacity". In order to make the work more accurate (for example, when processing small workpieces), a special sawing table is used, fixed with a clamp on the desktop. Cutting on it happens, as it were, on the contrary: it is not the jigsaw that moves, but the workpieces. The result is more accurate curved cut lines. To ensure the normal sliding of the jigsaw on the surface to be treated, another additional device is used - a replaceable plate (it can be made of different materials), which is attached to the support sole. More accurate straight cutting lines are obtained thanks to the guide bar and its adapter. It is not recommended to process many materials without pre-cooling - this problem can be solved by a reservoir with a cooled liquid, fixed on the support sole.

For the "care" of the tool itself, a universal lubricant is excellent: it will cool and lubricate, and, accordingly, extend the life of the saw blade.

When working with a jigsaw, in no case do not press on the saw blade, otherwise it will become very hot and, as a result, may become unusable.

When cutting a steel sheet, it is advisable to use a powerful electric jigsaw at high speed - the material heats up and becomes more pliable.

To avoid strong melting of the edges of the plastic, it is necessary to cut it at the lowest speed, but with a frequency of saw strokes of at least 1000 revolutions per minute. For figured cutting, a narrow saw blade with fine teeth is used. In places where there is no access to the mains, cordless jigsaws are used, but their power is low.

Like all power tools, the jigsaw should be blown out at the end of work and put in a briefcase or a strong case.

How to choose a jigsaw - tool features and working methods + video

More and more people prefer to cope with small construction tasks on their own, so they buy tools, and the task of choosing a jigsaw is not the last among the interests of this consumer group. We will conduct a short overview of the main types of these products and learn how to use them.

This tool was originally used for curvilinear cutting of wood, and plastic gradually got into the range of tested materials. Today, almost everything can be cut; a jigsaw for metal is no longer considered something exceptional and inaccessibly expensive.

The classification of this device is negligible, there are two large classes - manual and electric tools. The first is older, and the second is more effective, therefore it is much more popular today.

It is impossible to say which jigsaw is better, they already perform completely different tasks on the farm, let's figure it out.

A manual jigsaw is simple in design and consumes only human muscle power for work. Consists of an arcuate frame, handles, files, clips. Electricity is much more diverse. There are stationary power tools and portable ones.

All of them are powered by an electric motor, the rotation of which, with the help of a special mechanism, is converted into the translational movement of the guide file, which, in turn, is attached to the shank. The stationary jigsaw is stationary, and the blade protrudes above the body platform, the product must move around it.

The portable one has a handle, and a small platform with a file is at the bottom and moves along the workpiece to be cut, making a cut.

Despite the fact that working with an electric jigsaw is more convenient, the manual version has not completely left the store shelves. There are some explanations for this. It is much cheaper and easy to use, the file for it is very thin, therefore maneuverable.

When working, you can make a wide stroke with the tool, which better ejects the chips even when sawing a thick product.

A manual jigsaw is less dangerous for beginners and allows for artistic cutting of small parts, an electric jigsaw will not work in this regard, it is rougher.

However, it also has a number of disadvantages, the most noticeable is the frequent breakage of the saw blade due to its miniature size. Also, working with a manual jigsaw requires physical exertion and more time to work.

To make a file that does not reach the edges of the workpiece, you need to remove the end of the cutter, thread it into the previously made technological hole, then fix it again.

You can not saw at an angle and work with hard materials, the restriction usually ends with wood and plastic.

When buying such a tool, you should pay attention to many factors, despite the external simplicity. The shape of the frame will determine the distance of the cut from the edge of the workpiece, and its elasticity will affect the tension of the file and the mass of the entire tool as a whole.

A firmer, more resilient frame will stretch the blade better, giving it greater maneuverability and longer life. It is important to pay attention to the clamps, they must be strong, comfortable and reliable.

And when choosing files, for starters, take thicker and wider ones, and after you have mastered the work with a jigsaw, you can take more miniature files for more detailed small work.

The choice of a jigsaw is more interesting and varied, but you will have to decide exactly on the type of future work. One of the nice features can be the presence of a pendulum saw blade, when a special mechanism alternately changes the slope of the blade at the entrance and exit, which makes the work process faster, sawdust does not collect in the hole and does not slow down the cutter.

But this function should be turned on only with rectilinear movement, otherwise the seemingly quite strong file will break or bend. By the way, this is one of the enviable advantages of the tool. Moreover, the web is fixed at one end quite reliably and does not require dismantling when cutting through.

And the spatial arrangement allows you not to depend on the remoteness of the edge of the workpiece from the point of work.

Among other things, in an electric jigsaw, you can set the tilt of the file at a certain angle and make an oblique cut.

There are many more ways of cutting that a jigsaw can carry out, how to choose the right tool for a particular case, you can decide only by knowing the features of the work, but more on that below. In the meantime, consider another nuance - blowing the cut line.

This function arose as a consequence of the forced cooling of the motor by ambient air. The flow is drawn in at the back of the device, and released from the front, blowing off chips and dust, and the cut line becomes visible.

When choosing a tool, pay attention to the power, not only consumed, but also effective, which you will feel in practice.

And make sure that this power does not drop even more when the file touches the material, this is usually the responsibility of special mechanisms that maintain the frequency of the file strokes even under load.

It is important to be able to adjust the stroke frequency, because different materials will be more convenient to process with different revolutions.

Sawing wood with a jigsaw seems intuitive, but take your time, this is not always the case, let's get some points clear before work. For example, when cutting, you can’t push the jigsaw in the direction of the cut line, as if helping it, as the file, as well as the cut, heats up and deteriorates.

If the tool does not want to go by itself, it means that your file is dull or you should choose a different width or length. When working, fix the workpiece or hold it with one hand (the latter is inconvenient and degrades quality).

When working with hard materials, you can lubricate the file with oil or water, the process will go easier, and the blade will become less dull.

You should always put the tool in order after work (clean and lubricate). If you work at low speed, stop more often to cool the engine, it itself is blown worse in this mode. Take precautions, work with glasses.

For external accuracy of the final result, it is better to lay the workpiece face down, the cut from that side will be more accurate. And you should not cut clearly along the line, but next to it, in fact, when marking, do not make a margin for the width of the file.

When planning a goal, think carefully about whether a jigsaw is really the best for the job, sometimes it's an unnecessary hassle, and the best result will be obtained with a simpler tool.

If we have solved all the informational issues and understood the features of sawing, then it's time to understand the basic techniques of how to work with a jigsaw.

Normal move

The tool platform is attached to the edge of the workpiece, the blade is installed on the cutting line, the motor starts at low speed, and the file is inserted into the material. Moving evenly, we reach the end of the markup, there we slow down the tool and get ready to catch the cut off part, it is better to hold it so that it does not break off ugly.

Sawing at the edge

For this, a guide ruler is included in the kit, the holder for which is on the tool. It is installed parallel to the cutter and clings to the edge of the workpiece, and the jigsaw moves with a physically fixed distance from the edge.

Sawing with an auxiliary ruler

This method is used when you need to keep the same distance, and the guide ruler is too small. For this, any even bar is suitable, which is fixed with something on the edge of the workpiece, and a jigsaw platform is led along its edge.

Angle cut

It is used when the cut should not be perpendicular, but oblique, then the flywheel is unclenched (the bolt is released) and rotated to the desired angle, then clamped again. Sawing is more difficult this way, and the quality of the edge is not brilliant, but still, on occasion, the reception is quite feasible, which cannot be done at all with a manual jigsaw.

Sawing inside the workpiece blade

When starting from the edge is not possible, you need to make a hole somewhere in the inner region of the cut off contour. It should be a little more than the width of the file, a drill is usually used. Next, a cutter is inserted, and work begins. If the waste part (what is cut out and thrown out) is of a complex shape, then it can be done in several stages by drilling holes in several places.

circular sawing

The difficulty lies in turning the file without damaging the cut line, especially at small radii. Then you can act in several ways. Cut in small sectors so that there are no curved cuts.

And you can, without reaching the edge of the circle, make a wider cut so that the turn is painless for the file and does not “tear” the edge.

To do this, the cutter needs to be returned a little back and sawed forward a little, but already next to the existing cut.
