Fans of making various things at home appreciated the appearance on the market of such a tool as manual frezer as an alternative to a milling machine, despite all the possibilities that the latter provides.

Keeping a large device at home is often inconvenient - it takes up too much space.

Manual

Small milling machines are now represented on the market in a fairly wide range by almost all companies producing power tools.

Worth considering: A ready-made milling machine costs quite a lot of money, so sometimes you want to buy a similar device, but there is no such opportunity.

However, this is not a problem that can really stop real masters of their craft, since a router can be easily made with your own hands.

There are enough instructions for carrying out such a small feat at home, along with photo and video materials, attached drawings and detailed recommendations on the Internet.

The manufacture of such an instrument is accessible to many people who will be willing to spend several hours of time studying the materials, drawings and the very process of creating the device.

Device and tasks

In a simplified way, the design of a milling device can be described as follows: the engine of the device transmits rotation to a spindle on which a milling cutter (special attachment) is mounted.

When constructing a hand tool, the cutter is inserted into a specialized chuck, collet or jaw.

Do you know that: The main task of the tool is to process metal, wood, glass, ceramics, plexiglass or plastics.

A well-known example is the preparation of holes for door locks in a wooden panel. This can also be cutting threads or processing the edges of parts, milling grooves and cavities.

Rotation is provided by an AC motor. A variety of attachments can be used, depending on the material that needs to be milled.

The easiest material for milling is wood, therefore, as a rule, cutters for processing it will be the most common and cheapest.

For metals of varying degrees of hardness and viscosity, nozzles must be used that differ in their characteristics depending on the properties of the material being processed.

Of course, cutters for wood or metals are not suitable for processing glass or ceramics; for such materials it is necessary to select cutters with other characteristics.

Manufacturing

Of course, the main element of the milling device will be the engine. The most simple solution there will be a selection of an electric motor operating from a regular 220 Volt network.

An engine from household appliances available at home can serve as such. For example, an electric motor suitable for power and speed from a drill, hammer drill or grinder

Note: motors from small devices like a drill, for example, are not suitable for this task.

First you need to decide on a base for mounting the electric motor, which can be made of wood, plywood, chipboard or durable plastic. Since any engine is equipped with special fasteners for bolts, you can use them or special fasteners.

Expert advice: It is unlikely that you can do the fastening yourself due to the complexity of the design, so it makes sense to turn to craftsmen who can implement such a task.

Advantages and disadvantages

There are quite obvious advantages to making a homemade router compared to buying a similar tool in a store:

• costs are significantly lower than when purchasing a ready-made tool;
• ease of assembly of the entire structure;
• the ability to transform a manual milling cutter into a machine;
• processing of various types of surfaces.

Flaws:

• low processing speed;
• less strength compared to factory tools.

One way or another, the decision to buy a tool in a store or the preference for a homemade device remains with the master himself.

Watch the video in which an experienced master explains how to make a milling machine from a drill:

From improvised means. In order to produce what is planned, it is necessary to decide on the ultimate goal, namely, what operations are planned to be performed and with what accuracy?

You need to understand that the more universal you want to make a machine, the more difficult it is to implement your plan, and if you succeed, it will lead to a significant increase in the cost of the result, which may not be advisable, because assembling your own machine will be equal or even more expensive than the price of the factory one.

Here are a few examples of successful machine manufacturing based on the assigned tasks.

Man-made milling machine or beekeeper's assistant

A domestic milling cutter with a power of 1.1 kW and 30,000 revolutions was purchased.

Purchased router and homemade milling table

note

Important! When choosing, pay attention to the possibility of removing the sole from the outside, since the router will be located under the table, you will have to remove it to change the cutter, which is not very convenient.

Attaching the router to the table

I made the table myself, made a hole in the center from an eight-millimeter metal plate with an autogen, drilled holes for attaching the router and placed all this equipment on a table I made myself from bars. Q.E.D.

The result is a milling machine that fully satisfies the initial data for small and not super precise crafts, for example, planing a frame for honeycombs, making a groove or a quarter in a board.

The block was secured to the table with clamps to provide support during planing and to maintain the width of chip removal; the milling depth is selected on the machine itself. Simple and tasteful.

Universal stand for milling machine

A more interesting and, let’s say, “sophisticated” milling machine with convenient adjustments is presented below. During the creation process, a certain unification was achieved, as a result of which it became possible to use the stand for both a drill and a router, combining drilling, turning and milling into one whole.

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. The cutter is selected and installed according to appearance similar 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.

Milling cutter homemade machine from the grinder is located vertically, processing is carried out in the 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.

In a home workshop, there is often a need to sharpen, smooth an edge, or perform some other operation on metal or wood. Having a milling machine solves these problems.

But what to do if there is nowhere to put such large equipment or there is nothing to buy it for? The solution is a milling cutter from a drill.

A homemade device will greatly facilitate the processing of various materials at home.

The principle of operation of the milling cutter

The milling device works like this:

• the motor provides rotation and transmits it to a spindle made of durable and rigid metal;
• the spindle has an attachment for working on metal or wood - a milling cutter;
• it processes material that is fixed on the working plane.

A drill router can also work on ceramics, glass, and plastic. For each material there is a separate nozzle with its own characteristics:

1. For wood - simple cutters, not high-strength and without a large number of revolutions.
2. For metal - reinforced nozzle. Brass is especially difficult to machine with a router.
3. For glass and similar materials - cutters made of special alloys.

Using such a tool, you can screw threads, turn grooves and cavities, smooth and give the desired shape to an edge, and turn out holes. The drill will provide the manual machine with an electric motor of suitable power. When selecting it, take into account the power and rotation speed. The second parameter affects the quality of the cut: the more revolutions, the better.

The power depends on the material to be processed. For wood blanks, 0.5 kW is sufficient. But even in this case, experts recommend looking for more powerful device 1-2 kW. Such a router will be universal and convenient for working with various materials.

Assembling the base for a homemade drill-based router

First, think about the structure of the desktop and the layout of the router on it. You don’t have to assemble the tabletop, but buy it in a specialized store, but this is quite expensive.

For self-made use the drawings. A good table will provide comfort and speed up the process of working with a router. The base is a sheet of durable plastic or chipboard with a thickness of at least 12 cm.

Plastic is not afraid of moisture, but making a countertop from chipboard is faster and easier.

Attention! There are other options: MDF or phenolic plastic.

The tabletop is placed on guides. Provide the possibility of adjusting them to adjust the position of the table for your convenience. Also note that the space around the work surface should be protected. This is important when working with a hand router. In addition, the parts require a clamping mechanism.

Installation of a regulation elevator:

1. Cut out a small panel from chipboard and make 4 bars for support. The materials used must be durable and reliable.
2. Cut a semicircular hole on the countertop using a jigsaw or electric hacksaw.
3. Make slots for the clamps and thrust sheet.
4. Attach the panel to the engine using bolts or special fasteners.
5. The router must be fixed on the table on bearing units.
6. In the final stage of making the tabletop, sand all its wooden planes with sandpaper. The work surface must be located on a strong and durable base.

Making a mini-machine from a drill

This router does not require straps or pulleys: the cutter attachments are put directly on the motor shaft, as in the photo. But you need runners, carriages, and a threaded axle. When the shaft rotates, the carriage moves up and down along it. Sliding runners are guides. After setting the height, the carriage is fixed. The entire apparatus is supported by a housing that is mounted below on the countertop.

Attention! The engine and carriage should not wobble during operation. Otherwise, you will not be able to accurately process the material using a router.

The most difficult manipulation in the assembly is fixing the cartridge and the engine. You will have to buy a special adapter, and entrust its precise balanced installation to a mechanic with professional equipment. After assembly is complete, test the router:

• install a light nozzle;
• connect the device to the network;
• try to carry out simple operations;
• if the result is positive, perform more serious work;
• If everything is in order again, proceed to full operation.

Sometimes craftsmen additionally equip the device with gears for ease of control.

Features of operating a manual milling cutter

1. In addition to sanding, it is advisable to treat the wooden surfaces of the workbench with a special impregnation. This will increase the coating's resistance to negative factors.
2. Think separately about the location of the device control systems.
3. The milling cutter can be additionally equipped with a system for cleaning the working area from small chips. Come up with a pipe that will connect to the hose of a regular vacuum cleaner.

Advice. The video will help you understand in more detail the technology of making a milling cutter from a drill.

Advantages homemade device There are a lot of things before purchasing:

• availability of components for assembly;
• low cost;
• the ability to dismantle the mini-machine and use the cutter manually.

However, such a device does not reach the speed of professional devices and is only suitable for processing materials in small quantities. The milling cutter from the drill must be assembled in strict accordance with the technology. Only care and precision in performing work will allow you to obtain a durable and reliable unit.

How to make a router from a drill with your own hands: video

Many craftsmen are craftsmen who manufacture various wooden products, dream of having a milling machine in their workshop.

This dream is expensive, if we talk about factory equipment (stationary or manual). But there is a way out; you can, for example, make a wood milling machine for your home workshop yourself.

Despite the apparent complexity of the machine, it is actually simple. So, let's look at how you can make a router with your own hands.

It should be noted that all milling machines (professional, student and homemade) have a certain number of wood processing techniques.

The reason is the position of the wooden workpiece relative to the cutting tool. It can be stationary or move forward.

It is based on this that you can make homemade milling cutters from various electric cutting tools.

Milling cutter from a drill

This is probably the simplest wood milling machine that you can assemble with your own hands. The thing is that nowadays in any hardware store you can buy cutters that are made like a regular drill.

That is, their design contains a shank that exactly fits the dimensions of the internal diameter of the drill chuck. By inserting a cutting tool into the chuck, you can use the drill as a hand-held wood router.

In this case, it will be necessary to take into account that when working with a manual milling cutter from a drill, it is necessary to firmly secure the workpiece. It should not move or sway. The quality of the milling work performed depends on this.

Most often, the workpiece is secured with clamps, and, as practice shows, the more clamps were used, the more firmly the workpiece is secured. You can also use a regular vice for fastening.

This option is used only if it is necessary to process the end of the workpiece.

The difficulty with using a homemade router from a drill is that it will not be easy to maintain the required processing size. Of course, if it comes to chamfering, then there will be no problems with a hand router made, but to make a groove, you need a steady hand. 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 strictly defined position. There are many options here, differing from each other in the type of wood processing.

For example, if you need to make a groove in a wooden piece:

• To do this, firstly, a cutter is selected and installed in the drill, which is similar in appearance to a drill. But it has a peculiarity - the working edges of the tool are located in the front part (like a drill) and in a longitudinal position.
• Secondly, it is necessary to clamp the workpiece well.
• Thirdly, special clamps are attached to the drill itself, attached to the limiter (it can be made of chipboard, plywood or boards). By resting the stop against the workpiece, you can move the homemade router along the line that determines the position of the future groove. Look at the photo below, which shows a drill with a wooden stop.

In principle, a stationary homemade milling machine is made according to exactly the same design as the factory one. That is, it includes:

• Milling cutter. Here you can use the same drill, grinder, or make several devices in the form of a small electric motor and a spindle for a wood lathe.
• Tabletop. It is characterized by indicators of the area and the fasteners installed on it, plus a ruler that will show the size of the cutter offset.
• Bed. The requirements for a milling machine bed are strength and reliability, because it is the load-bearing part of the machine on which both the table top and the cutter will be mounted.

The most difficult option among desktop milling units is to make a machine yourself using a separate electric motor and spindle. Firstly, all this must be purchased.

Secondly, installation requires the manufacture of a frame on which these devices are installed, strictly adjusted to each other. Therefore, it is recommended to use ready-made electric tools to assemble the milling machine.

Let's look at how you can make a router (stationary) from an angle grinder.

Before making a wood milling machine, you need to understand that this equipment processes workpieces either in a vertical plane or in a horizontal one. Therefore, the installation position of the working body depends on the choice of processing method.

For example, let’s consider a homemade milling machine made from a grinder, the cutter of which is located vertically, that is, processing will be carried out in a horizontal plane.

The bed can be of any design (drawings are optional here), it is better if it is made in the form of a frame made of metal corners. A sheet of chipboard is attached to it using bolted connections. It is reliable and durable.

• The place where the working shaft of the milling cutter from the grinder will stick out from the table is determined. Here a hole is made, the diameter of which is greater than the diameter of the shaft.
• The angle grinder is secured with two clamps, which themselves are attached to the table top with screws and nuts.

The head of the screws should be located on the side of the countertop surface where the workpiece will move. Accordingly, the fastening nuts will be located on the side of the angle grinder. The screw heads must be installed flush.

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

• One end of it 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. Typically, a bolt and washer are used to secure the cutter on this side, which press the working tool against the adapter. Therefore, a threaded hole is made in it at the end to match the diameter of the bolt used.

Be sure to install guides along the tabletop along which the workpiece will move. These can be boards, pieces of plywood or chipboard.

The last two materials are most often used, because with their help you can create guides of various configurations, which allows you to mill the workpiece in different directions according to different patterns.

Guides are removable products that are attached to the frame with self-tapping screws.

Comparing two options: stationary and manual milling machines, it should be noted that the first determines the accuracy of the processes performed, regardless of the number of revolutions. And accordingly, the quality of the resulting structures is many times higher. Although the manual manufacturing method is much easier, making it yourself is not a problem.

Do-it-yourself wood milling machine - basic options and assembly principles

All photos from the article

Every owner who wants to adequately equip his own home workshop strives to install a small but multifunctional machine in it.

In the modern market, the cost of such equipment is quite high, so you have to make it yourself.

Experienced craftsmen claim that it is quite possible to make a vertical wood milling machine with your own hands, the main thing is to have the desire.

Photo of a homemade machine made from a drill.

What options are there?

A homemade wood milling machine for a home workshop, as you understand, is not made out of thin air, so you will have to spend money on materials and main working units. Often the price of such a design depends on the cost of the main unit, which includes the electric drive and the cutting mill itself.

The simplest and most affordable milling machine can be made from a regular electric drill or hammer drill. If the tool is rigidly fixed on a vertical bracket and the cutter is clamped into the chuck, then you can process small parts by holding them in your hands or fixing them in movable clamps.

Factory copy-milling machine.

Manual frezer.

The choice of operating principle, size and functionality of the equipment depend on exactly what parts you are going to process. From the same electric drill you can make a machine with a movable working head for cutting high-quality grooves in three-dimensional products, such as wooden doors. In this option you get a milling and drilling machine.

Another common direction is to use a manual router as the main unit. Of course, the price of such a tool is often higher than that of a drill, but its advantage is that it is initially designed for high-quality milling; you just make a frame for it and expand its functionality.

Theoretically, any electric motor can be used as an electric drive. But a normal drill or hand router has a built-in gearbox and can therefore safely withstand horizontal and vertical loads. Bearings holding the shaft of a conventional engine may not withstand such tests and quickly fall out.

Assembly principles

To competently complete the drawings of a wood milling machine with your own hands, you need to have an engineering education, and, as you know, not everyone has it. But the machine is not a spaceship; a good sketch is often enough.

Detailed sketch of a milling table.

Using a drill

For most DIYers, separate instructions are not required to firmly secure the drill in a vertical position to the rod. In addition to the rod itself, 2-3 metal clamps are sufficient. But you can call such a device a machine only if you make a movable platform for the workpiece.

In principle it is not that difficult. On the table, directly under the drill, you need to attach two parallel guides; in the simplest version, wooden blocks are suitable for this.

A wooden platform with clamps rigidly fixed to it is installed between them; the part will be clamped into them.

The platform can be moved manually or a lever can be attached behind it.

Rigidly fixed drill.

• A more functional machine can be made from an electric drill. To do this, use several wooden blocks and 4 smooth metal tubes, preferably aluminum. The idea is to provide controlled movement of the drill in 3 planes. Up - down, left - right and forward - back;
• First you will have to build 2 rectangular frames. The frame lying on the table is responsible for the back and forth movement. 2 parallel metal tubes are installed on it, along which the second frame, located in a vertical position, will move;
• On a vertical frame, parallel to the table, the next metal tube is cut between the bars. This guide will be responsible for the movement of the mechanism to the sides;
• To attach the drill itself to such a frame, we need a couple of strips. The drill will be fixed on a block that is mounted between the ends of these planks;
• On the other side of this improvised lever, the strips are drilled and placed on the vertical frame tube;
• Another tube is fixed parallel to the table on a block with a drill. At the second end of this tube, strictly parallel to the drill, a handle for monitoring and control is mounted;
• The dimensions of all these nodes may be different, and the connection principle is shown in the photo.

Movable drill.

Using a hand router

At the beginning of the article, we talked about a homemade vertical machine for wood milling. This means that the working tool is installed in a vertical position.

If it is more convenient to install a drill vertically above the table, then it is better to permanently install a hand router into the table from below the table top.

Accordingly, before you make a wood milling machine yourself, you need to choose a table or at least a reliable tabletop.

But you can’t just cut a hole and screw the tool on underneath. The tool base plate must be flush with the base table and securely locked in place.

Therefore, as a rule, the tabletop itself consists of two layers. The bottom layer has a hole the size of the router. And the top plate is made of two parts, a mounting plate for the router and a base plate, which is permanently attached to the tabletop.

The principle of joining parts.

As can be seen in the diagram, a wide rectangular section is cut out in the center of the top plate, after which the remainder is glued or screwed to the base tabletop.

A hole is made in this rectangular sector along the diameter of the working cutter. Next, the working plate is screwed to the tool. Now you can insert and secure the plate into the niche.

The video in this article shows several options for assembling such structures.

Conclusion

Homemade floor milling machine.

Situations often arise when you need to make a groove, carefully trim the edge of a board, or make a part of a complex shape. Typically this work is done using a router. In a well-equipped workshop, any tool and all the necessary machines are at hand.

But what if, for example, instead of a workshop there is a garage, and only a drill is available. You can resolve the issue at your nearest power tool store. But, as usual, it all comes down to either finances or the fact that the milling tool is needed only for a while, and then it will simply gather dust on the shelf. As you know, there is a way out of any situation, and specifically from this one - a do-it-yourself router from a drill.

What is a drill router?

The drill acts as a drive. A cutting tool (cutter or drill) is clamped into the chuck and processing is performed. In this case, the body of the electric drill is mounted on some base or mechanism that ensures the necessary location of the cutting part relative to the workpiece or part.

The operating principle is similar to the factory versions of milling cutters. The design of the mechanical part is also similar or completely replicates the elements of a non-handicraft device. The exception is the drill mounting parts. In addition, the design of the mechanism depends on the material of manufacture.

A milling device can be simple and contain a minimum of parts and assemblies, but if necessary, nothing prevents you from “expanding” the capabilities of an electric drill by building a fairly complex structure. It all depends on your own capabilities and requirements for the functionality of a homemade tool.

What is needed for making

You can make a router with your own hands from a drill using any available materials. The main requirement: the structure must be durable, the presence of backlashes and distortions is not allowed, the electric drill must be securely fastened.

To make parts you can use:

• Chipboard or multilayer plywood with a thickness of 12 mm or more;

• cutting boards of suitable thickness;

• wooden bars.

It is also possible to use other materials. For example, you can use metal. A base made of thick plexiglass or acrylic is a good idea. The surface being treated will be visible through such material.

The parts are connected using self-tapping screws. For reliability, all fixed joints can be glued with any suitable glue (carpentry glue, PVA, etc.).

Bolts or studs may be needed to secure moving parts. diameter 6 – 8 mm. They will need nuts, both regular and wing nuts. Some connections may require washers. It is possible to use furniture fittings: guide mechanisms, various fasteners, and so on.

Manufacturing process

In everyday life, a vertical manual router is often used. It has the easiest design to repeat. It is enough to make a stand with a mount for an electric drill, and the device is ready to perform simple operations. An example of such a homemade unit is in the photo below.

The process of making such a base is quite simple:

• The first part that is best to start with is the base (sole). It is necessary to cut the workpiece into a round or oval shape.

• Next, make a hole for the cutter. It should be offset relative to the center of the part, taking into account the thickness of the side post.

• Depending on the dimensions of the electric drill, a stand of the required size is made and secured to the base with self-tapping screws or furniture fittings.

• The rigidity of the fastening is ensured by a spacer (kerchief). The inner sides of this part must have an angle of strictly 90°.

• The next element is the drill mount. You can use a pipe clamp, as in the photo, or make a clamp from wood or plywood and secure it with self-tapping screws.

• As an additional fixation, a stop is installed above the drill.

This option is suitable for doing rough work or will serve as a temporary alternative to a full-fledged tool. To perform more precise operations, you will have to develop a more complex design.

There is nothing stopping you from equipping your “homemade product” with adjustable cutter reach or the ability to change the angle of inclination. It is possible to use a drill in a tabletop milling machine. To do this, the electric drill is installed vertically under the working surface.

Features of working with a homemade milling device

Making a router with your own hands from a drill is not the most difficult task. Difficulties arise in using such a device. It is worth considering that the power tool is not designed for this method of use and working with it will have some features and even disadvantages.

The first thing to consider is the rotation speed. The milling machine motor can have up to 20,000 rpm. For an electric drill, this indicator is around 3,000. It follows that you will have to limit yourself to using cutters designed to operate at low speeds, and the rotation speed regulator should be in the maximum position.

The situation is similar with power. The motor of a simple electric drill consumes about 500 - 600 W. The power of the milling machine is 1 – 2 kW. This means that a homemade milling machine can handle processing of not too hard materials (wood, plywood, plastic).

The precision of machining with a milling cutter is also not ideal. There are no gears or gearboxes in the design of a factory router. Electric drills use a gear to transmit rotation from the motor to the chuck. Because of this, there may be backlash, and therefore, beating and vibration may occur, which will negatively affect the quality of work.

Video: Router from a Bosch drill

A simple design will most likely not provide for adjustment of the depth of cut. You can align the cutter or drill by clamping the shank in the chuck at the required height.

Also, do not forget about safety precautions. The chuck is not the most ideal option for attaching a cutter. At high speeds, vibration can cause a poorly tightened cartridge to loosen.

The power button for a homemade router will be located in an inconvenient place. The device should be held securely with your hands during operation.

Of course, a homemade router made from a drill has a lot of disadvantages, but there are also positive aspects. Try drilling into a wall with a regular router. Theoretically this is possible, but it is more convenient to do this with an electric drill. To do this, simply remove it from the mount and use it for its intended purpose.
