Milling nozzle on the drill with their own hands

How to make a router with your own hands?

Disc angle grinder or in simple parlance “angle grinder”. this is an indispensable tool in the arsenal of every craftsman. In addition to its functional versatility, experienced craftsmen can share some “secrets” and tell you how to make other no less useful power tools on the basis of the angle grinder.

Such include a manual milling machine. a specialized tool for working on wood. If you need it for a certain type of work, and there is neither the time nor the desire to buy it, masters tell you how to make its analog in the conditions of the home workshop.

Design

Manual milling machine. a device with a rotating in a chuck milling cutter, which is fixed vertically on the supports of a special bed platform. The height of the cutter relative to the sole of the platform is regulated by locking blocks and allows the working surface to enter the wooden workpiece to the depth set by the master. This allows you to saw wood, and apply decorative recesses, and make slots and holes of different configurations.

Making a router with their own hands from the angle grinder will require the master of time and certain efforts, but the resulting wood milling machine on its characteristics will not differ from industrial models and, if necessary carpentry works, will cope with the tasks at hand.

When constructing a router instead of an angle grinder you can use an electric drill. the only difference will be in the configuration of the fixing mechanism, as the rotating shaft of the grinder is located perpendicular to its housing, and the shaft axis of the drill is set along it.

Except for this design feature, in both cases, the main thing to do the master. is to make a bed platform, which will be attached to the selected power tool, and make up from an old chuck from a drill collet holding the mill.

Components and Assembly Algorithm

It is possible to make a milling machine out of a drill, which almost every home craftsman has, but it should be borne in mind that such a device will not be able to fully replace the production model. This is explained by the fact that the chuck of an ordinary hand drill is capable of rotating at a speed of 3000 rpm, while a commercial router is able to ensure that the tool used rotates at a speed of up to 30000 rpm. In addition, the gearbox of a domestic electric drill is not designed for intensive loads, which will quickly lead to its malfunctioning state.

The schematic diagram of the simplest vertical drill stand

Meanwhile, the simplest milling machine, made from improvised materials with minimal financial outlay, can successfully cope with many technological tasks. To make your own milling machine from an electric drill, you must find the following materials and tools:

• several pieces of chipboard or thick plywood;
• Clamp, by means of which the drill will be fixed on the base of the device;
• bolts, self-tapping screws and other fasteners;
• Feather drill or drill bit with a diameter of 40 mm;
• Standard set of locksmith’s tools.

Scraps of slats, pieces of plywood, metal corners. all can be used to make a simple router stand

The process of assembling the self-made router is as follows.

• From the sheets of chipboard or plywood is assembled the basis of the future cutter, which includes a horizontal base and the vertical part, which will be fixed to the electric drill. The dimensions of the sheets of chipboard or plywood, from which such a construction will be made, are calculated depending on the dimensions of the electric drill used as the basis of the homemade machine.
• A 40 mm diameter hole is drilled in the horizontal base of the device, which is necessary to provide tool access to the machining area.
• On the vertical pole of the device by means of a bolt is mounted the clamp, in which the electric drill is fixed. The drill should be positioned so that the lower end of its chuck is a few millimeters from the horizontal base of the power drill.
• To make the position of the drill on the vertical stand more stable, you can fix a small block of wood on top of it to act as a stop.

Adjustment of the depth of cut with such a router is carried out by changing the position of the electric drill in its fixing clamp.

A stand with height adjustment by means of a lever

How to make the milling machine of the above-described design more convenient and functional? For this purpose, it can be equipped with a simple microlift, which will be responsible for moving the electric drill in the vertical direction. To make such an elevator you will need the following consumables and accessories:

• Two metal rods, which will act as guide elements;
• platform (carriage) for fixing the electric drill, made of particle board or thick plywood;
• threaded axis and nut, which will be responsible for the movement of the electric drill in the vertical direction;
• elements, ensuring the fixation of the electric drill in the required position.

Stand with height adjustment with a threaded rod

The principle by which such a homemade milling machine works is quite simple and is as follows.

• By rotating the threaded axis, the carriage with the drill attached to it moves in the vertical direction.
• Once the electric drill and the tool fixed in its chuck will be exposed in the desired position, the carriage is fixed by means of fasteners.

Naturally, the entire construction of such a self-made cutter, the work of which is well demonstrated by the video, must be fixed on a solid base. The latter can be the surface of a work table or workbench.

Machine from an old electric motor

Self-made milling machine, by means of which many technological operations are performed quite successfully, can be made without using an electric drill. In order to make such a device, you will need the following consumables and accessories:

• drive electric motor, as which you can use the electric motor from an old washing machine and other household appliances;
• chuck, in which the cutting tool to be used will be fixed;
• adapter, by means of which the drive motor shaft will be connected to the chuck;
• Sheets of chipboard or thick plywood to make the base and vertical guide of the homemade router.

Homemade machine tool on the basis of a Soviet three-phase motor

Choosing for self-made milling machine motor, keep in mind that the power of the latter must be in the range of 500-1100 W. The higher will be the power of the drive motor, the greater will be the depth of the milling machine.

A very important requirement in the manufacture of homemade milling machine is the absence of backlash in the contacting elements of the device. If you neglect this requirement, you may be faced with the fact that the processing performed with such a mill will not be distinguished by high accuracy and quality. In addition, the quality and accuracy of machining performed even on a homemade milling machine is seriously influenced by the characteristics of the cutting tools used.

Materials and tools

To perform the assembly of the fixture, the following materials and tools will be required:

• A motor that operates from the mains;
• Electric jigsaw (in the absence of. hand saw);
• drill bit;
• screws, locknuts, self-tapping screws, clamps;
• cutter;

• chuck;
• 4 bars of wood;
• quick-clamping clamps;
• Particle board. for the base of the machine.

You do not need to be an expert to operate these tools. Check beforehand if the electrical tools work and be sure to follow safety rules.

To make a hand router from a drill with your own hands, you first need to deal with the table. Processing the ends, as well as milling grooves for jointing by the method of “tongue-and-groove” will be more convenient to do with a milling table with protruding tools. They have a simple design and drawings are easy to work out by yourself. A small workbench-type table will also work. The lid must be reversible and a hole must be cut in it.

Its size should be approximately 0.5 cm larger than the maximum diameter of the cutter to be used. Perpendicular to the table will be installed bar, which will stand parallel to the side at such a distance that the spindle axis of the attached electric drill coincides perfectly with the center of the hole.

The power tool body should be attached to the bar with the supports and clamps, and in the normal state of the table the chuck will be located under the cover, and the cutter, inserted in it, will protrude. During processing, the piece of wood will move across the surface of the table, and rest against the template, which will result in the milling.

It is also possible to fix the tool in other ways. The main thing is that the center of the hole coincided perfectly with the axis of the cutter, and the chuck and the switch are accessible. All machining elements must be attached rigidly, without any misalignment.

The simplest machine

They must be placed strictly perpendicular, that is at an angle of 90 degrees. Make a hole in the footplate for the tool outlet. The stand will be equal in width to the dimensions of the body of an electric drill and 2 cm longer. On it with a clamp, which is placed above the chuck, will be attached to the drill.

When cutting the sole, or rather the base of the structure, you should draw a square on a sheet of plywood, and its sides should be equal to the width of the body of the electric drill. On the two sides that are adjacent to it, you need to add strips that are equal to the thickness of the plywood. Mark the center of the tool location and make the hole with a feather or core drill.

Next, the sole should be cut along the contour, and the angle opposing the joint of the braid and the stand should be rounded. On the reverse side, drill a hole at 0.4 cm and make recesses, which will be countersunk under the heads of the self-drilling screw, using a drill at 0.8 cm. Otherwise the flats of the screws will scratch the table when they protrude again, and also interfere with the fit of the sole. You’ll get a skew.

On the bottom of the sole you can glue a thin rubber band or even a piece of linoleum. This will ensure that the trimmer glides smoothly during operation. Using an angle, set the stand in place and screw it down. The braid will be attached with one side to the base, the other to the post, which will provide rigidity to the structure.

If you have a locksmith’s experience and the required set of parts and components, you will be able to mount the homemade mill on the side cylindrical stands. Put springs on them from below, which will lift the drill up. Mounting is done using metal corners, self-tapping screws and staples. The milling depth can be adjusted with the stop screws.

Assembly algorithm

Before you start making a hand router based on an ordinary electric drill, you need to prepare all the necessary materials and drawings, with the dimensions and,

How the drill will be attached, which will replace the hand router:

• Mark on the sole or table the center of the spindle axis.
• Cut a hole for the outlet of the power tool.
• Next, lay the electric drill on the stand and make marks of the position of the stop and clamp to fix everything.
• Screw the bracket and stand at right angles.
• Secure the tool body to the base plate.

The machine, which will be made by your own hands, must be strong, have no warps and backlashes. It will then be possible to work on it like an ordinary router.

Copying rings and templates

The copying sleeve for the router is a fixture with a protruding rim that slides along the template and thus sets the movement of the router in the desired direction. Such a ring can be fixed on the cutter’s foot in different ways: screwed down with screws, screwed into a threaded hole, inserted by special tendrils into the holes in the foot of the tool.

Calculation of cutter offset when using a copying sleeve

The diameters of the copying ring and the tool used should be close, but it is important that the ring does not touch the cutting part of the cutter. If the diameter of the ring exceeds the lateral dimension of the copying cutter, the template, to compensate for the difference between its size and the diameter of the tool, must not exceed the size of the workpiece to be machined.

Milling template in the form of a ring can be secured to a wooden workpiece by means of double-sided adhesive tape and clamps, which hold both parts of the template to the work table. After milling the template, check that the ring is pressed firmly against the edge of the template during the milling operation.

Cutting an oblong hole with a template and a copying ring

Milling templates can be used not only for the entire edge of the workpiece, but also for rounding the corners. Applying such a template for the router, you can perform on the corners of the processed wood product roundings of different radius.

Templates used to work with a hand router can be equipped with a bearing or a ring. In the latter case, the following conditions must be met: the ring must exactly match the diameter of the cutter or the design of the device must include stops that allow the template to move away from the edge of the workpiece and thereby eliminate the difference between the radii of the tool and the ring.

With the help of templates, which can also be adjustable, it is possible not only to mill the edges of the processed woodwork, but also to create shaped grooves on its surface. In addition, if you make a template of the appropriate design, which is not very difficult, with it you can quickly and accurately cut grooves for door hinges.

Cutting round and elliptical grooves

To cut circular or elliptical slots in wood with a hand router, circular cutters are used. The simplest circular cutter bar consists of a boom. One end is connected to the cutter base and the other end has a screw and a pin. The pin is inserted through a hole which acts as the center of the circle whose contour is used to form the slot. To change the radius of the circle of the groove, for which such a scroll for the router is used, it is enough to displace the rod relative to the router base. convenient to use are circular tools, which are designed with two rods instead of one.

The simplest circle rod often comes with the router

The circular workbench is a fairly common type of accessory used to work with a router. With their help it is very convenient to perform milling of shaped grooves with different radii of rounding. As mentioned above, the typical design of such a device, which can be made and by your own hands, includes a screw with a pin that has the ability to move through the groove of the device and thus allows you to adjust the radius of the created groove.

In cases where the wood router or other material needs to create a hole with a small diameter, another type of jig is used. The peculiarity of the design of such devices, which are fixed on the lower part of the router base, is that their pin, installed in the central hole on the workpiece, is located under the base of the used power tool, and not outside of it.

Using special accessories, the hand router can create not only round, but also oval holes in wood. The design of one such fixture includes:

• base, which can be fixed on the woodwork to be machined by vacuum suction cups or screws;
• Two shoes that move on intersecting guides;
• two mounting rods;
• bracket that connects the base of the fixture to the cutter.

Thanks to special grooves in the bracket of such a device, its base plate can easily be aligned with the base of the cutter. If this tool is used to mill a circular contour, one shoe is used, but if it is used for an oval contour, both shoes are used. A cut made with such a device is of higher quality than if it was made with a jig saw or a band saw. This is explained by the fact that machining with the cutter used in this case is carried out with a tool that rotates at high speed.

The result of working with a homemade compass is a round hole with even edges

Metal cutter

The burrs can be used with an electric drill or screwdriver. Metal drill bit, which is also called a burr, performs scraping and grinding operations on metal surfaces. Grinding and reaming holes to desired dimensions can also be performed with a burr. The equipment on which the burrs are mounted must have a high rotational speed. The working part of a burr can be very small. This mini-tool is used for engraving and jewellery work, making dies and foundry molds.

Bores are often used in conjunction with a drill, sometimes called a dremel. This name comes from the German company “Dremel”, which produces equipment and tools for milling and engraving work. When engraving on wood or metal with a screwdriver or an electric drill a flexible shaft and a nozzle for fixing a cone.

For woodwork

Machining wooden workpieces is not as difficult as machining metal. With the help of drill cutters for wood you can perform both roughing and finishing processing of workpieces. Cutters with a shank diameter of 8 or 12 mm are used for hand tools. Different types of router bits are used for work on different types of wood materials. Types of wood milling cutters:

• Tape grinders. Used for rounding corners.
• Disk. Used for cutting various grooves and grooves.
• Tumblers. for creating semi-circular grooves.
• V-shaped. Slots. for cutting grooves in flat surfaces.
• Dovetail joints. for making dovetail grooves.
• Edging. for edge trimming.
• Cylindrical. for processing flat surfaces.
• End mills. for production of recesses and indentations.
• Tapered. chamfering the edges.
• Drills. designed to make holes in wood.

To perform various technological operations, the required type of tool is selected. Safety rules must be obeyed when working with cutting tools. In the process of processing pieces of the processed material fly off, cutting tool breakage is also possible. For safety purposes, protective goggles and gloves should be worn.

What is the assembly

In addition to the different geometries of the actuators, they are designed for different raw materials. Such factors affect the composition of the cutting part, which can be made of:

• fast-cutting metals;
• hard alloys;
• mineral ceramics;
• ceramic-metal (diamond);
• of wire cord array.
• Solid. one material is used;
• welded. shank and teeth are made of different materials, which are welded together;
• soldered. the blades with the base are connected by soldering;
• Prefabricated. consisting of different components; standard fasteners. bolts, screws, nuts. are used for fixation.

For casting, steel of high-alloyed grades with high heat resistance is selected.

Cutters are quenched to produce a martensitic structure with increased wear resistance.

Heat treatment is performed according to the technology:

• light. after heating the steel is cooled in a special solution;
• intermittent, so that cracks do not form on the finished product;
• continuous. used in exceptional cases according to the principle of accelerated cooling;
• stepwise. first the workpieces are in a hot environment, and then they are placed in the open air.

In order for the products to meet high performance specifications, they must go through a quality hardening process.

Homemade cutters

There are many ways to make metal drill bits with your own hands. The basic ones are:

• A silicon wheel from a lighter can be placed on a suitable axis, thus obtaining a well-functioning piece of router bits.
• Glue pieces of sandpaper to a plywood cylinder to get a sanding drum.
• Sharpen the dowel to obtain an end or cut-off nozzle.

Each master can be inventive and produce such tooling, which is required for the performance of specific works.

Special applications

Created by our own hands design has obvious advantages, the key among which can be called the following:

• Home-made machine will cost an order of magnitude cheaper than the factory one;
• A milling machine from an electric drill makes it possible to work on different types of surfaces;
• Work on the assembly of the device is quite easy to produce, not counting the moment of wiring;
• ease of use;
• easy maintenance.

Significant disadvantages of homemade equipment are few. The main disadvantages include the following points.

• The hand router, made from improvised materials, is not durable.
• The machining speed of the parts is too low.
• The resources of the electric motor, taken from an old household appliance, are not enough to work with simple materials and surfaces, particularly metal. This defect can be eliminated. For this purpose it is desirable to take a high-speed electric motor from a torch. This will make it possible to adjust the number of revolutions for different materials.

This is how, adhering to simple tips, you can mount a router from an ordinary electric drill. Adjust elements thoroughly and use only high quality materials. Do not strive to save money on an electric drill, remember: when the device loses its relevance, you can dismantle the machine and use it for its real purpose. Do not rush to throw away the table and elevator. they can also be dismantled and compactly stowed in a drawer until the next time.

Basic parameters and classification

The parameters by which drill cutters for woodworking are divided into different categories are:

• main purpose;
• dimensions;
• the shape that the cutting part has;
• design features;
• manufacturing material.

Main geometrical parameters of wood burrs

Types according to purpose

To perform milling work on wood using an electric drill today use a variety of tools, as technological operations with this material can be different. Depending on the main purpose among wood cutters are the following types.

Using such a tool, rounding corners of wood products is carried out.

These cutters are used to cut V-grooves in flat wooden surfaces. With such a tool, you can perform various patterns and inscriptions on the product, as well as handle the edges.

These are wood cutters, with which grooves and grooves of varying width and depth are cut on the surface of the processed product.

Such cutters are similar to disk cutters in their purpose, but allow you to create wider grooves on the surface of the product. Cutters of this type are used in window production, where they can be used to cut grooves in wooden frames to install glass.

With this type of cutters it is possible to create semicircular grooves on the end face of the workpiece. Timber end milling cutters with a bearing are used for the production of decorative furniture laths.

These are tools with a cutting part made in the shape of a reverse cone. They can be used to create “dovetail” grooves in wooden products. Exactly such grooves are used to create open and hidden tenon joints of two or more parts made of wood.

These wood routers are used for cutting the edges of woodwork. Edge milling cutters may be designed with a bearing, which, by resting against the edge of the workpiece, ensures its correct position and limits the depth of its plunge cut.

Wood cutters of this type can be made with straight or helical cutting edges. Such tools are used for machining flat surfaces.

These router bits are also designed for planar surface finishes. Unlike solid drills, they have cutting teeth on the face part.

These router bits are used to chamfer the edges of a workpiece. Such wood burrs used for drill mounting can also be equipped with a thrust bearing that limits the depth at which the tool plunges into the wood.

These wood router bits are used for cutting complicated notches and cavities on the workpiece surface.

These are cutters used to form elements of complex configuration on the surface of a wooden product.

Types according to design

Milling tools used in combination with drills can have different design. Thus, a distinction is made between solid and prefabricated wood milling cutters, which should also be chosen depending on the characteristics of the material to be processed.

One-piece milling cutters are made from a single steel billet; therefore, their bodies and cutting parts are made of the same material grade. These tools are inexpensive, but can be used for cutting not too hard materials. Naturally, operating life of this cutter type is short.

One-piece cutters made of tool steel

wear-resistant and durable are wood cutters of prefabricated type, the body of which is made of ordinary steel. Their cutting teeth are made of carbide plates that are brazed to the tool body and cannot be re-sharpened during operation. These cutters can also be used for work on harder materials at high production rates.

Carbide-tipped wood cutters

Regardless of the type, the wood router bits for drills can be either pointed or serrated. The former have flat front and back surfaces, and are sharpened on the back surface. The big disadvantage of cutters with cutting teeth of this type is that their resharpening can change the geometric parameters of the tool, in particular its diameter. Such disadvantages are deprived by milling cutters with occipital teeth, where only the front surface is flat. Since the sharpening of such a tool is performed exactly on the front surface, it is possible to carry out this procedure repeatedly, without worrying about the fact that the geometric parameters of the cutter will change.

Milling machine from a drill with their own hands

Given the fact that the series milling machine belongs to the expensive equipment, the question of how to make a small milling machine from a drill is very relevant. Such a machine, used in a set with wood cutters installed on a drill, is indispensable in the construction and repair of a country house, as well as in the performance of many other works.

Getting down to making a self-made milling machine, it is necessary first of all to make a table for it, which must be stable and reliable. Plywood, which should not be less than 12 mm thick, is often used for this purpose. Supporting elements can be made of four wooden bars. An important part of such a homemade device is a platform-restrictor, whose task is to ensure the correct position of the cutter in relation to the machined surface. You can make such a platform from a sheet of chipboard or thick plywood, cutting out a piece of the desired size and rounding its corners. In the center of the platform, a hole is drilled, which is necessary for the exit of the wood cutter.

Construction of the mechanisms for moving and holding the drill vertically

The drill itself is fixed on the stand, made of chipboard, with the help of clamps. The length of such a stand should approximately correspond to the length of the drill itself, and its width should be sufficient to place the power tool and fasteners on it. Stand and fence platform are connected to each other strictly at an angle of 90 °. When fixing the drill to the stand with clamps, position it so that the cutter inserted in its chuck extends beyond the surface of the base plate by the required amount. To increase the strength of the resulting structure, you can further strengthen it with a piece of chipboard, connected with self-drilling screws to the stand and the platform-restrainer.

Homemade coordinate table for machine tool

Using an ordinary drill, you can make an even more functional and easy-to-use milling machine, if you install the power tool on a homemade bed, equipped with a rack with a simple microlift. It is also possible to make such a machine tool from wood, except for the propeller, on which the microlift with the tool attached to it will move.
