Do-it-yourself milling cutter from a drill: manufacturing workflow. How to make a router with your own hands from a drill How to make a milling machine from a drill

To make a router with your own hands, you will need to make drawings. The diagrams indicate key design details and their parameters.

The accuracy of the work performed depends on the power of the router.

Design Features

The milling machine is used for processing edges, chamfering and decorative carvings. The router, which is used to work with soft metal, is equipped with special knives. The unit in question consists of the following parts:

• motor;
• spindle;
• milling cutter

The working cutter is located on a spindle, which is rotated by a motor. Some tools of this type operate on 1-phase AC power. You can make a hand-made homemade router with a small DC motor.

The choice of cutter depends on the material to be processed and the purpose of the tool. For woodworking, simple designs with low speed are used. It is more difficult to construct a unit for working on metal, because this material has higher strength and rigidity.

When the device is connected to the power supply, the spindle rotates, and sharp knives cut the material (wood, metal). The spindle must be made of durable material that meets certain standards of hardness and rigidity. Rotation speed affects the accuracy of work. The number of revolutions depends on the density of the raw material. Experts recommend making a homemade device with a regulator.

Classification of units

According to the method of application, hand routers are classified as top, lamella and edge units. Top milling cutters can be submersible (with a moving motor) or fixed (with a motor fixed in one position). The classification of narrow-profile units depends on the material and parts being processed:

• for working with gypsum boards;
• tenoning machines;
• to create grooves.

You can assemble a vertical router for woodworking with your own hands from an electric motor, a cutter and a chuck. The motor is removed from any electrical appliance, and the cartridge from the hammer drill. The base (chipboard or PVC sheets) is attached to the motor. The engine and cartridge are connected with a special adapter. If necessary, this work is entrusted to specialists. Then the knives are selected and installed. The device is ready for use. A stand-alone CNC device is used to create computer-designed products (laser cutting, drilling, milling and engraving).

Universal device

Based on the resulting apparatus, a universal machine can be manufactured. A stand is used for this. The machine is suitable for rough work on wood, but it will not be possible to perform precise, high-quality work with its help due to the fact that it does not operate at high speed.

To create a multifunctional machine you will need:

• MDF board (1.5x1.5 m);
• accessories.

To cut out parts, use a drill and a jigsaw. The finished machine is not suitable for working with hard metal. When manufacturing a CNC machine, you will need an aluminum profile with a cross-section of 80x40x4 mm, which is cut into beams (4 - 460 mm each, 2 - 1300 mm each).

Experts include the following advantages of a do-it-yourself hand router:

• suitable for processing most surfaces;
• affordable price;
• ease of use;
• ease of assembly;
• inexpensive service.

The revolutions of a standard motor from a household appliance are not enough to provide high-quality processing. Equipping the design with a powerful engine helps eliminate this drawback. To do this, use a motor from a modern hammer drill.

For shallow sampling of wood blanks, a motor with a power of up to 500 W is used, but it will stall. Experts recommend installing a motor with a power of 1100 W or more. A 1-2 kW drive allows you to process wood as usual with any type of cutter.

Then you need to decide on the speed. The cut will be more accurate if there are more revolutions. With motors designed for a 220 V network, the connection will not cause difficulties. A three-phase asynchronous motor is connected using a special star-delta circuit. The connection diagram ensures smooth startup of the device and operation with high power.

Conclusion on the topic

Before making a homemade device, it is recommended to find out its operating principle. When the axis begins to rotate, the carriage with the motor moves up or down along it. The runners serve as guide stops. The screw is necessary to firmly fix the carriage after adjusting it in height. The supporting body is attached from below to the workbench lid, holding the structure.

The carriage with the motor must be securely fixed and immobilized to ensure uniform sampling. Moving the swing arm to the side and equipping it with homemade gears will make the design convenient to use.

If a ready-made table is not available, then when manufacturing it, take into account the fact that different materials behave differently during operation. A wooden table is not resistant to moisture, but absorbs vibrations well.

The guides for the stop can be made of plywood or chipboard. This will allow you to adjust the horizontal position. When manufacturing and using the tool, safety precautions must be observed.

Hi all! This article will talk about how to make a router from a drill with your own hands using available materials. There are situations when you need to do a certain specific job, but to do it you need a tool that is quite expensive. I don’t feel like buying it for one or two times. Then you think about how to replace it with what you have.

All home craftsmen have such a tool as a drill. Therefore, they are trying to adapt it to various needs, and not just for drilling. People use it with the help of various devices such as lathes, drills, sharpening machines, grinders, mixers and much more. So you can also make a router out of it. Moreover, you will need very inexpensive materials for this.

But it’s worth mentioning one point. No drill can fully replace a router. This is due, firstly, to the fact that its revolutions are only about 3,000 per minute, while the router reaches them up to 30,000. This means that it will also not be possible to process the surface cleanly. And, secondly, its gearbox is not designed for such loads, which will lead to its rapid wear if it is operated in this mode for a long time.

Well, now that we have figured out all the pitfalls, we can tell you what you will need. And you will need very little:

We take laminated chipboard or plywood and use self-tapping screws to assemble a structure like the one in the figure below.

The hole in the base is drilled with a pen or a 40 mm crown. Calculate the sizes of pieces of plywood or chipboard based on the dimensions of your existing electric drill.

You will need to unscrew the self-tapping screw from the clamp. A bolt will be screwed in its place. We drill a hole in the vertical wall for it to insert it from the back and screw it into the clamp, which is located in front. The height of its location should be such that the drill chuck is a few millimeters from the base.

To fix the electric drill, a small rectangle made of chipboard or plywood is screwed on top. The end result should be something like this:

Now all that remains is to clamp the cutter into the chuck and work. The height of the cutter is determined by how deep it is immersed in the chuck. And in order for the cut to be straight, you can attach a board with a straight edge to the side of the structure and rest against it.

This simple design will help you perform milling work if you only have a drill in your arsenal. Well, if you still want to do this kind of work on an ongoing basis, then it’s better to buy a router. The best prices for them. You can come in and see for yourself.

And that’s all for me - see you again!

1. Milling cutter from a drill
2. Stationary machine

Making a milling machine for your home workshop is easy. You just need to take into account that all machines (professional, student and homemade) have a certain number of wood processing techniques due to the position of the wooden workpiece relative to the cutting tool. The sample being processed can be stationary or undergo translational movements. Therefore, homemade milling cutters are made from various electric cutting tools.

Milling cutter from a drill

This is the simplest wood milling machine that you can assemble with your own hands. In any hardware store there are cutters made like a regular drill: their design includes a shank that exactly fits the dimensions of the internal diameter.

But when working with such a manual router, you need to firmly secure the workpiece. It should not move or hesitate. Most often, the workpiece is fixed clamps . The more clamps are used, the more firmly the workpiece is secured.. Sometimes a regular vice is used. They are used when it is necessary to carry out end processing.

The problem with using a homemade milling cutter from a drill is the difficulty of maintaining the required processing size. The slightest trembling in your hands will ruin all your efforts.

It is necessary to make devices for the milling machine from a drill that will hold the electric tool in a certain position.

If you need to make a groove in a wooden piece:

1. A cutter is selected and installed, similar in appearance to a drill. Feature - the working edges are located in the front part (like the drill) and in the longitudinal position.
2. The workpiece is clamped well.
3. Clamps are attached to the drill, attached to a stop made of chipboard, plywood or board. By resting the stop against the workpiece, you can move the homemade router along the line and determine the position of the future groove.

The photo shows a drill with a wooden stop.

Stationary machine

What you will need for production:

• Milling cutter - drill, grinder, several devices in the form of a small electric motor and a spindle for a wood cutting machine.
• Tabletop.
• Bed. It must be strong and reliable: this is the load-bearing part of the machine on which the tabletop and cutter will be attached.

The most difficult option is to manufacture a machine from a separate electric motor and spindle. It is easier to make equipment from ready-made electrical tools.

A milling machine performs processing in a vertical or horizontal plane; the installation position of the working element depends on the choice of processing method.

The cutter of a homemade grinder machine is located vertically, processing is carried out in a horizontal plane.

The bed can be of any design (drawings are optional). It is better to make it in the form of a frame from metal corners. Attach a sheet of chipboard to it with bolts. Then:

1. Determine the place from where the working shaft will come out.
2. Make a hole with a diameter larger than the diameter of the shaft.
3. Attach the grinder with two clamps, which are attached to the tabletop with screws and nuts.

The screw head is placed on the side of the tabletop surface where the workpiece will move. The fastening nuts are from the angle grinder side. The screw heads are installed flush.

For a homemade machine, you need cutters that resemble cutting discs in their fit on the shaft. They do not have grooves for keys. They, like the discs, are attached to the angle grinder with a clamping nut. If there is a need to use key-type cutters, then an adapter is made:

• One end has a threaded connection. With this side it is screwed onto the angle grinder shaft at the place where the clamping nut fits.
• The second end is made for fitting the cutter onto the key. Usually a bolt and a washer are used for fastening (they press the working tool against the adapter), so a threaded hole is made at the end to match the diameter of the bolt used.

Guides are installed along the tabletop along which the workpiece will move.. Most often, pieces of plywood and chipboard are used: with their help, you can create guides of various configurations, which allows you to mill the workpiece in different directions. Guides are removable products attached to the frame with self-tapping screws.

Using a stationary milling cutter, the accuracy of the processes performed is determined, regardless of the number of revolutions. The quality of the resulting structures is higher than when using hand tools. Although the latter is easier to do yourself.

Many craftsmen are faced with a situation where making a router from a drill with their own hands is an urgent need. Sometimes it is necessary to smooth the end of an unevenly cut part or make a groove for an edging in chipboard. To do this you will need a special tool. It is not difficult to find it on sale; the phraser can be bought in specialized stores, but not everyone can afford such a purchase due to its high cost. Another option is to look for a Chinese equivalent. But you can make a manual router from a drill much faster.

A milling cutter from a drill can be made quickly, but is used to a limited extent.

A router is a tool for shaping edges, joints, and routing wood pieces, as well as performing other functions. This is a fairly versatile tool that allows you to perform different types of work with it.

The mechanism has a fairly simple structure. There are only three main components:

• cutter;
• engine;
• spindle.

The operating principle is not particularly complicated. A working cutter is put on the spindle. The entire structure is driven by a motor.

Three-phase motors are usually used for the manufacture of milling cutters; models operating from a single-phase network are less common. Some craftsmen can make a milling cutter from small DC motors. But when creating a mechanism, it is better to follow the standard method: this will eliminate difficulties with power supply.

When choosing an engine, you need to take into account two indicators: the number of revolutions and power.

The quality of the cut depends on the number of revolutions. It will not be difficult to connect a regular 220 V motor. A three-phase asynchronous motor is connected using a completely different circuit: star-delta. This can provide the most power to the device.

The motor power of the device for working with wooden workpieces can be up to 500 watts. But such a device will not live up to expectations, and it will also be unstable. Therefore, the savings will not pay off. The optimal power for a manual milling cutter from a drill is more than 1000 watts. A 1-2 kW drive will allow you to use any cutters and operate in normal mode.

Working cutters can be used in different ways: the choice depends on the material to be worked with and the type of operation. Simple cutters are suitable for processing wood that does not require high speed and strength of the material. Metal is more difficult to process; brass is especially difficult to process. Cutters made of various alloys are suitable for processing materials like glass.

The spindle must be made of hard and durable metal. The requirements for these indicators are increased.

Making a base for a router

When making a cutter with your own hands, you need to complete the work in several stages. To do this you will need a cutter, a motor and a chuck.

At the first stage, you need to decide which network the tool’s motor will operate from. For household work, you need to make a tool that can operate from a 220 V power supply. In this case, you can take the motor from almost any household appliance that can be found at home.

If the engine receives power from a three-phase voltage network, finding a suitable unit will be much more difficult. Most likely, you will have to contact a specialized store or workshop, or ask at the factory.

Before you begin making the tool itself, it is worth preparing the base on which it will be installed. Assembling the table will allow you to process larger parts with much less effort. For the base, some simple material, such as a sheet of chipboard, or durable plastic, is suitable. The sheet thickness should be about 12 cm.

When making a table or base for a router, it is necessary to take into account the qualities of the selected material. Making a table from chipboard is more convenient and faster. During operation, it will partially absorb vibrations, but the material is afraid of moisture. It is better to make the lid from a more durable material: phenolic plastic or MDF boards.

Guides for parts can also be made of chipboard or plywood so that it remains possible to adjust their position.

When working with a hand router, the unused space around the working router must be covered. To fix the part being pushed, it is not superfluous to install a clamping mechanism.

A small panel is cut out of the material for the base. For support you need to prepare 4 wooden blocks.

On the surface of the base you need to cut a semicircular hole using an electric hacksaw or jigsaw. Then make holes for the thrust sheet and fasteners.

The finished panel is attached to the engine using bolted joints or special fasteners.

The router table is an indispensable part. If you can’t assemble the base yourself, you can buy a table.

You can purchase it in large specialized stores. The price will depend on the functionality, but even the simplest table with a good coating will not be cheap.

Making a hand router

When making a router from a drill with your own hands, you need to remember some rules. First of all, it is important to remember that the adjustment lift is made of solid wood and is installed on the surface of the table. For this reason, the rotation force must be quite large.

A machine of this type is made without using pulleys and straps. In this case, the cutters are mounted on the motor shaft. To make an elevator you will need a main body, carriages, sliding runners, a threaded axle and a fastener for fixation.

When the axis rotates, the carriage moves up or down along it. The runners act as guides. Then the height is set, and the carriage is installed using fasteners. The entire structure is supported by a supporting body; it is fixed from below to the workbench lid.

It is important to ensure that the carriage and motor do not wobble, otherwise this will affect the operation of the router: the cut will be uneven. This device allows you to set the reach of the cutter above the table surface.

Some craftsmen advise additionally making gears and equipping them with a homemade design, and also changing the position of the swing arm, installing it on the side rather than on top.

Next comes the most difficult part - securing the cartridge and engine. To do this, you can use a special adapter. You can buy it in the store. But the installation will be more difficult: doing this work yourself is very difficult, it is better to entrust it to specialists.

After installing the adapter, we can assume that the hand router is ready for use, and we can carry out the first test. First, a simple light cutter is installed. The instrument is connected to the mains. If after this the router works correctly, you can proceed to its permanent operation. Now you can use it to screw threads, drill holes on wooden parts or process edges.

Quite often, homeowners have quite complex needs that can only be fulfilled with the help of a specialized tool, for example, cutting a groove for an edging in the end of a chipboard, or smoothing the end of a part that was clumsily cut with a jigsaw. There is one for these purposes, but is it needed to do one-time work??

I think there is no point in paying 3,000 rubles to purchase a tool if you decide to make a table with your own hands - the savings are not enough to cover the costs... What to do? My hands are itching, and my soul wants to create!!!

The milling cutter is made from a conventional drill into the chuck of which the cutter is clamped. To make this device, in addition to the drill and cutter itself, you will need 4 pieces of chipboard, a hacksaw (any, but better, a jigsaw), a 30-40 mm drill (feather or crown) and a clamp for attaching water pipes to the wall.

At the clamp, instead of a screw that is screwed into the wall, we screw in an 8 mm screw.

From laminated chipboard we cut out a base platform measuring approximately 250x200 mm (preferably with rounded corners). In the center of the workpiece we make a hole for the cutter.

In the rack for attaching the drill, a hole is drilled for a clamp, which, together with the drill, is fixed to it with an 8-point screw and a pair of locknuts. You can simply saw off the leg and secure it with two nuts. The installed drill is supported at the end by a small stop, which is a small “cube” made of chipboard, which is secured with a pair of self-tapping screws.

The base and the stand are connected with self-tapping screws or confirmations (the caps must be flush with the working surface) with the addition of a stiffener. It is imperative that in a part with an edge, at least one angle must be strictly 90 degrees.

The assembled structure (see photo) can be quickly equipped with a drill with a cutter clamped in the chuck, and just as quickly removed by tightening/unscrewing the nuts on the clamp.

The result is such a universal device, which has most of the functionality of a conventional router.

Of course, this solution is not without its drawbacks. It is not suitable for long-term work, because... The drill gearbox fails due to “non-target” loads - it is not adapted to them. In addition, it is not very convenient to adjust the offset of the cutter - to do this you have to change the position of the cutter shank in the chuck.

But for performing one-time work, such a self-milling machine is the method of choice. If you are constantly tinkering, then it’s better for you - over time it will pay for itself)).
