DIY facing from an angle grinder

Assembly work

Prepare two corners with a length of 350 mm and with shelves of 50×50 mm. On the top shelf, cut the scarves at an angle of 45 ° along the two edges of each of them. Such an angle can be easily calculated with a plumbing square if you attach it to the profile so that the outer edges coincide with the edges of the profile. Then use a scribe to make a mark in the inner center of the letter “G”. The top corner created by the profile flanges and the mark will point to the 45 ° line. Weld a square from the resulting blanks, but so that its diagonals are equal (check them with a tape measure).

Now cut out a square of 350x350x3mm sheet iron and drill holes in the frame at the corners through it to bolt the bed to the frame. It is not necessary to weld the sheet to the frame, since in this case the miter saw from an angle grinder can be used not only as a stand, but also as a hand circular to cut sheet lumber (chipboard, OSB, Fiberboard, plywood).

Make a channel from two pieces of an angle 50 mm long, and then weld it to the bed so that the part is in the middle of the edge with an indent of 2-3 mm from the edge. This will act as a support for the angle grinder arm. Weld the door hinge to it a little later.

Now cut off two blanks 150 mm and 200 mm long, and then cut one shelf of a 150 mm corner to 30 mm. From these two parts, weld the hollow profile, as shown in the top photo.

Cut another piece with a length of 120 mm, and reduce one of the shelves to 20 mm. Make another piece 50 mm long and also cut one shelf to 20 mm. Then weld the letter “G” out of them at 90 °, but a short profile with an edge outward. Then weld the resulting part to the self-made profile so that at the end of the lever on the open side a flattened letter “P” is formed perpendicular to the profile. Sand the edges and welds of the lever you made so as not to cut your hands with burrs in the future.

Advice! When working, the plumbing square should always be at your fingertips. Check all angles with it, which should correspond to 90 °.

Until the lever is welded to the rack, you need to make fastenings on it along the head (gearbox) of the angle grinder. Please note: there are two holes on the gearbox for screwing in the handle, so the letter “P” should clasp the head like a clamp, and on the letter stands, drill holes in the diameter of the threaded mounting holes. Reducer thickness Einhel angle grinder for disc Ø 125 mm, 70.6 mm. Therefore, my U-shaped clamp from the inside turned out to be 50×70.6×50 mm. Measure your model with a barbell and adjust the clamp to fit it.

One bolt for attaching the angle grinder to the lever is screwed through the upper hole in the gear housing for the handle, and the other through the lower one. Make sure the holes on the “P” line up exactly with the lever. After fastening, the body of the angle grinder should stand strictly parallel to the lever and strictly perpendicular to the welded support from the channel.

Weld the non-separable door hinge with one side to the support post and the other to the arm, but make sure that the assembled structure strictly matches the edges of the frame along the perpendicular and parallel. Now screw the bed to the frame, fix the angle grinder with the edging disc for metal there and cut the strip in the sheet. Remove while the angle grinder, so as not to interfere and strictly parallel to the slot, place a mark in front of the support post and make a cutout there with a depth of 1-2 mm (we left 2-3 mm of a free edge when the support channel was welded). This cutout will be needed to guide the circular.

From the bottom of the clamp, screw the tool steel spring, working in compression, with one end to the crossbar “P”, the other to the bed. Choose the length, depending on the spring itself and the size of the angle grinder.

Now you just have to expand the slot made earlier with the cutting disc by 2 mm in one direction and the other, so that the circular saw passes there with a gap. That’s it, now with the bed installed on the frame, you will get a miter saw made from an angle grinder, and if you remove the frame, it will be a manual circular for cutting sheet lumber.

In this article, we will figure out how to make a miter saw from an angle grinder, but at the same time you will have options where you can use your device as a circular or trimming metal profiles. In the course of the story, I will mention the details that will be needed for cutting lumber, and which for steel products. In fact, you get a versatile unit that will be a great help for your home workshop.

Getting started

It should be noted right away that for cross-cutting it is best to use a small angle grinder (angle grinder) where a Ø 125 mm disc is provided. Of course, as an option, an angle grinder for Ø 115 mm and Ø 150 mm is also suitable here. Here you will already choose from the tool that you have in stock and which you are ready to repurpose.

Do-it-yourself trimming from an angle grinder

What is required

First of all, you need to collect all the necessary materials and tools that will be needed to assemble this structure:

  • steel corner with shelves 50×50 mm;
  • steel sheet 350x350x3 mm;
  • a selection of bolts and nuts;
  • good compression spring (tool steel is best;
  • one-piece door hinge (canopy) of good quality;
  • locksmith’s square;
  • welding (gas or electric);
  • metric tape measure.

A cut-off made from an angle grinder can serve as a cutting tool for both wood and metal. To do this, it is enough to change the disk and the purpose of the unit will change along with it.

1.3 Milling machine

The angle grinder is a very versatile tool. If there is an urgent need to make a milling machine from an angle grinder with your own hands, it will not be a burdensome matter, since the design is very simple and does not take up much space. At the same time, you can use it for milling work on metal not regularly, but as needed.

  • metal plate with a minimum thickness of 3 mm;
  • a section of a rectangular shaped pipe with a length of 20-25 cm and a width of at least 5 cm;
  • two metal corners;
  • fasteners.

Each master always has his own workplace. As a rule, this is a table or workbench located in a room in which noisy work can be carried out (garage, shed, etc.). It is such a table that will be needed for a device that will allow you to carry out milling work on metal.

DIY angle grinder cut-off machine

On the edge of the near left corner of the worktable, a plate bent at a right angle is installed for attaching an angle grinder. The principle is that the fixed tool should protrude from the edge of the table just as much as the disc needs to rotate freely.

See also  Disc for cutting porcelain stoneware with an angle grinder without chips

For this, a medium-sized disc is selected, and in the future, without moving the attachment of the angle grinder, a larger or smaller diameter cannot be used.

After the angle grinder is installed and secured, the profile tube is installed. It should have a cut with a depth of 2.5 cm and a width of 2 mm more than the thickness of the working disc (1 mm on each side). The pipe is welded to the angle grinder, which in turn is attached to the table in front of the angle grinder attachment plate.

The installed fasteners must be located in such a way that, hanging from the edge of the table, the angle grinder with its disc goes into the cut of the profile pipe.

Thus, it turns out that when rotating, the disc is surrounded on three sides by a shaped pipe to a depth of 2.5 cm.This allows you to work on metal, holding the workpiece in your hands and resting it on a support (shaped pipe).

Fixed frame-table for attaching an angle grinder

This kind of home-made installation can also work as a cut-off saw, and in some emergency cases, it can easily replace a lathe.

But not for metal, but for wood, if you provide for the presence of a stop for the cutter and a movable element for fastening the workpiece. to the menu

Crosscut from an angle grinder

Technical characteristics of cross-cut with a broach, assembled by hand:

  • disk revolutions. 4500;
  • cutting length. 350 mm (much higher than that of a middle-class factory tool).

The tool can be removed from the table and the angle grinder can be used as usual.

  • The rotary device of the tool is installed on the pivot of the car wheel (pivot), it is held by a ball bearing for 150 mm (if you can find more, it will do).
  • We attach the ears to the outer side of the bearing by welding to fix it on the base. It is fixed by means of M6 screws.
  • To protect against shavings, the clip is covered with a box.
  • We make the broach from the shock absorbers from the truck (broken ones will do). Oil is poured out of them, holes for ventilation are drilled, which should be tightened with a mesh from dust and shavings.
  • To avoid a jerk when starting work, the saw is supplemented with a soft start module, which slightly reduces the speed.
  • The last stage of work is the manufacture of protection for the disk.
  • works very noisy;
  • to adjust the accuracy of cuts in wood, trimming of bars is used, after which the thrust is fixed rigidly and you can work clean.

How to make your own circular from an angle grinder

From time to time in a home workshop, a tool such as a circular saw is required. However, for these infrequent tasks, buying a saw is not profitable. In this case, it is recommended to make a circular saw driven by an angle grinder. This option is much cheaper than buying a factory saw to run for a couple of hours. You can see an example of such a homemade product here.

DIY wall chaser from an angle grinder

The angle grinder can be used for tasks such as cutting cuts in a wall. These are cuts for laying wiring, pipes, and other elements. If you take a stock angle grinder for such work, the immersion depth of the disc is very difficult to control. To solve this problem, a special frame can be made.

Such a frame is made in the form of a sole with a stop, with the help of which the tool can be moved along the wall with a uniform deepening. Thus, the strobe of the desired depth will be learned. To make such a wall chaser, you need to remember about such details as a protective cover and a special dust collector. For the latter, a bag can serve, but it will be more convenient to connect a hose from a vacuum cleaner.

What you can do with an angle grinder: DIY from an angle grinder

The angle grinder is perfect for use on a stationary machine and as a more accurate tool, and as a motor with a gearbox for all sorts of homemade products. The angle grinder is very often used for construction, repair, and installation tasks. an angle grinder is advantageous in that the number of options for its application increases with the number of attachments used.

How to make a cutting machine from an angle grinder with your own hands

The widespread use of grinders has led to the fact that there are a great many of them on hand. And in case of minor violations, professional workers refuse them for safety reasons.

But home craftsmen cannot afford such a luxury. From an angle grinder, they make cutting and disc machines, chain saws for cutting metal and wood. Why do cutting machines from an angle grinder?

Anyone who has worked with an angle grinder knows that it is absolutely impossible to cut a workpiece from a pipe, and especially from a profile one. It is necessary to mark each side with a square and turn the pipe over when cutting. And still, the dimensions may differ by 0.5 mm. And when welding thin-walled parts, the metal burns out due to a defect of incomplete fit.

An angle grinder with sufficient power is required to cut metal. Models with a circle diameter of 180 mm or more are quite suitable.

Although models with a 125 mm wheel are suitable for working with thin-walled products, the installed wheel with a larger diameter remains without a protective cover, which is fraught with grass when the cut-off wheel breaks.

Final recommendations

it should be reminded once again that the angle grinder is designed to work with a different material and in its own speed mode. Statistics indicate a large number of accidents associated with the use of self-made devices based on an angle grinder. Using it as the basis for a circular is a problematic and dangerous solution. The creation of the machine should be carefully considered from the point of view of safety in order to protect yourself from the possibility of serious injury.

Trimming from various scrap metal

This is a rather heavy bevelling on a stationary metal table. It will take some effort to manage it. But in the end, the saw mechanism moves smoothly, without jerking, do-it-yourself trimming is easy.

  • electric motor power. 2.2 kW;
  • disk revolutions. 2800;
  • cutting depth 80 mm.

Materials and tools required for assembly:

  • 900 W electric motor;
  • a metal sheet;
  • metal corner;
  • channel;
  • hinge group;
  • powerful spring;
  • angle grinder;
  • welding machine;
  • file.

The bed is made of adjustable supports, a metal corner and racks from the old bed. The working surface is a metal sheet like the surface of the table, in which we cut a hole, we process the edges with a file with our own hands.

  • The pendulum stand for the saw is welded from a channel mounted on a sheet of metal, its height is about 80 cm.
  • The support for the electric motor is made in the form of a movable metal plate mounted on hinges. When installing an electric motor, a spring is used as a stabilizer. Then you can do without a pendulum and belts.
  • Tension belts are adjusted with a conventional eye bolt, the swingarm for the mechanism is also made of metal.
  • A disc with a diameter of 420 mm is installed on the facing as an executive tool.

A miter saw is a rather dangerous equipment, collecting it with your own hands, you need to take care of protective boxes and covers. After all, there are much more errors in the operation of home-made equipment than factory equipment.

How to make a homemade miter saw (trimming) for wood with your own hands

The trimmer design is similar to a circular saw mounted above a work table. Its main advantages are: compactness and low weight. Thanks to this, saws are used not only in workshops, but also on construction sites. Unfortunately, DIY tools are quite cumbersome and heavy. It is convenient to operate them in stationary mode.

The miter saw is designed for a single task. trimming the ends of lumber at different angles. Due to the fact that the workpiece is stationary on the table during cutting, the cut is neat and clean. Craftsmen dealing with woodworking give preference to this particular tool. over, hand-made saws have been successfully used for years.

Advantages and disadvantages of homemade trimming

  • Making a tool with your own hands saves money. For example, about 500 rubles were spent on the revision of an angle grinder. The cost of a homemade table and sawing mechanism is available to most craftsmen;
  • main parameters: cutting depth, rotation frequency, disc diameter, engine power, table dimensions, are selected according to their own needs;
  • having assembled the tool with his own hands, the master will easily find the cause of the malfunction and fix it.
  • The service life of the tool depends on the quality of the raw materials, and homemade products are usually collected from all kinds of trash;
  • homemade trims are rarely powerful enough. Indeed, for the high-quality operation of the equipment, a careful selection of parts is required;
  • sometimes the funds saved on the purchase of a factory tool are spent on repairs and revision of a homemade one;
  • craftsmen often save on their safety by not equipping the table and saw with protective devices;
  • Factory saws are equipped with a graduated scale that accurately indicates the cutting angle of the tree. It is difficult to build such a mechanism on a home device.

A few more convenient and interesting homemade products, including an excellent stationary, mobile and made in a couple of minutes from several plywood and screws:

The purpose of the miter saw

Unlike a circular saw, the miter saw in question can be used exclusively for trimming the ends of various sawn timber. Some models allow you to maintain a certain angle. In the case under consideration, trimming takes place when the workpiece is stationary, which determines a better cut. This moment determines the fact that a homemade miter saw in workshops is quite common, since only when using it can you make a clean, even end. Self-made saws can serve for several years without major repairs.

How to make wood trimmers with your own hands

A wide variety of equipment can be used for wood processing. Such material lends itself to processing, which determined its popularity in the production of various things. A cross-cut machine is used to change the size and shape of the workpieces. Its design is similar to that of a circular saw, however there are several differences that determine the popularity of the machine. The main advantages include low weight and overall dimensions, which makes it possible to install equipment in a home workshop. You can make a do-it-yourself wood miter saw, but as a rule, homemade products will be more cumbersome and less productive. It is convenient to operate this equipment in a stationary mode.

Miter cut based on angle grinder

To solve this problem, an angle grinder is often used. It is ideal for making your own end-face miter saw. A homemade version will have the following technical characteristics:

  • the rotations of the disk of the angle grinder should not be less than 4500 rpm;
  • the cutting length is 350 millimeters. Note that this indicator is significantly higher than that of a factory instrument, which belongs to the middle class.

The created design allows you to remove the angle grinder from the table and use it as a regular tool.

When considering how to make such an execution option, we note the following points:

  • the cutting tool is mounted on an axle, which is represented by a car wheel. This moment determines the possibility of facing at an angle. To fix the swivel mechanism, a bearing with a diameter of 150 millimeters is used. To fix the angle grinder, a special mechanism is used, which is attached to the pivot axis. After a certain time, it is recommended to lubricate this axis, as there is a possibility of a squeak;
  • to fix a certain angle during the production of the machine on a bearing, from the outside, special lugs are welded on. The fixation is carried out using a screw, for example, M6. The ears should be fastened so that there is not a large distance between them. Otherwise, there is a possibility of a strong backlash, which will significantly reduce the processing accuracy;

The last step in production is the creation of the saw blade. This element eliminates the likelihood of foreign bodies entering the cutting zone. Your own miter saw can be used at home.

However, the design under consideration also has significant drawbacks that should be taken into account. These include:

Flattening an Anvil Face with the Angle Grinder!

  • DIY miter saw is very noisy. This is due to the peculiarities of the angle grinder. During processing, noise appears, which is almost impossible to reduce;
  • the cross-cut machine is used for high-quality processing of end surfaces. That is why quite a lot of attention is paid to the accuracy of the positioning of the angle grinder with the disc relative to the workpiece. To adjust the position of the angle grinder with a disc, trimming bars are used. The traction should be fixed with a bolt, after which processing can be carried out.

The drawings of the trimming machine determine that it can be installed quite simply in almost any workshop. It should be borne in mind that the structure is small, and the workpiece can be quite large. In order to eliminate the likelihood of loss of accuracy during processing, the structure should be fastened to the base.

Particular attention is paid to the type of disc installed. Initially, the angle grinder was designed for metal processing, which determines the presence of a large number of discs for metal. But there are also discs for wood processing, which have their own characteristics.

note that there are quite a few drawings that can be used when creating a miter saw. Some are easy to implement, others are difficult to implement.


On the Internet, I often met devices with which an angle grinder can be used as a miter saw. This prompted me to make my own version, which allows you to cut blanks also at different angles.

On the Internet, I often met devices with which an angle grinder can be used as a miter saw. This prompted me to make my own version, which allows you to cut blanks also at different angles.

Miter Saw Angle Grinder. STEP-BY-STEP

From sheet metal 5 mm thick, I cut a plate with dimensions of 240 × 50 mm. I welded a bracket from an iron bar d 10 mm to it. A bolt welded to the top of the latter

I picked up a shaft d 25 mm with an already drilled through hole (the workpiece can be turned from a metal rod). I cut the thread for the bolt on the bracket with a tap inside the hole. I screwed the shaft onto the bolt to check the smoothness of the movement. Then I welded two M10 threaded rods to the shaft wall along the edges. To make them “walk” less during work, a metal strip 5 mm thick was welded between them

At the base (metal plate) I marked the place where the slope will be, it is necessary so that the angle grinder adheres to the plate with the whole body. Marked and drilled a hole in this area so that it coincides with the hole for the handle on the tool.

Having clamped the base in a vice, with a hammer he bent its edge to the desired angle. For reliability, I welded the plate between the pins to the shaft and aligned the welding on emery. To attach the holder to the table, I cut out two metal plates 100x50x 5 mm in size and drilled holes for the studs in them. When all the details were ready, I painted them

From a sheet of Chipboard I cut a rectangular tabletop of the desired size. Having stepped back from the edge of the short side about 20 cm, I drilled two holes. I screwed one nut onto the studs and strung a plate, set the holder on the table in the holes, strung another plate from below and screwed one more nut each. On the base, I fixed the angle grinder. In addition, I screwed a guide to the table, which I set in two planes relative to the circle of the angle grinder. at an angle of 90 and 45 degrees. You can start cutting.

On the tabletop, you can draw several corners and set a guide according to the marks. To do this, it is enough to loosen one (closest to the device) bolt, and unscrew the second. Turn the rail to the desired angle and tighten the bolts again.

Table circular saw

Sometimes there is a need to change the width of the board or the thickness of the bar. The best option for this kind of work is a circular saw, especially if there are a lot of boards. For cutting boards of small length (1-2 m), the table version of the circular is very useful. It is not necessary to buy such a machine, you can do it yourself from the same angle grinder.

The design of a circular saw is much more complicated than a miter saw. The time of contact of the saw blade with wood is quite long, therefore, the reliability of fastening the body of the angle grinder to the bed should be higher.

This is how one of the options for a table circular may look like.

The photo shows that the desktop consists of two planes:

  • the upper table is designed to advance the workpiece;
  • the lower one serves as a stop for the grinder.

The disc passes through a groove in the top surface. If the angle of contact of two planes is provided with pivoting hinges, then it will be possible to adjust the working height of the saw blade to reduce the area of ​​rubbing surfaces.

The head of the bolt is clearly visible on the upper surface of the table, with the help of which the angle grinder is fixed. The protruding bolt limits the width of the board to be cut. You can cope with this problem by laying another layer of plywood.

It is rather inconvenient to turn the angle grinder on and off with the keys on the case. If the key can be fixed in the working position, then a socket with a switch should be installed on the outside of the machine.

Make your own large angle grinder stand and metal chop saw

The abutment angle should be as long as possible in order to prevent the board from deviating from the cutting direction. It is better to fasten the corner so that you can change the working distance between it and the disc: then the width of the cut part will also change.

Stationary circular

It is possible to use an angle grinder as a working mechanism in stationary conditions. The bed in this case will have a slightly different design. The stationary option implies the availability of free space and a large amount of work. Therefore, the entire structure can be made more solid, more massive, and, therefore, more reliable.

The frame of the bed can be made from a corner by a welded joint. Bolted and other types of detachable fasteners lose grip from constant vibration, the structure begins to stagger.

A working table made of a wide board or thick plywood is attached to the top of the metal frame. The workpiece will move along it. The stop angle is equipped with a movable mount for adjusting the cutting width.

It would be nice to provide for the adjustment of the table height or the removal of the disc above its surface. then it will be possible to cut longitudinal grooves in the board.

On the side of the machine there are controls: a socket and on / off buttons. In the stationary version, it makes sense to exclude the key on the body of the angle grinder from the diagram. If there is enough space, a high power sander can be used as a drive.

How to make a sawmill from an angle grinder is shown in this

Miter saw

Trimming, that is, cross-cutting boards or bars at right angles, is better if you use a special device.

You can also make such a machine from an angle grinder with your own hands.

  • To do this, an angle grinder with a disc for wood is fixed on a turntable perpendicular to the direction of the length of the board so that the plane of the disc is directed strictly vertically. One attachment point should be located in the area of ​​the gearbox, and the second at the opposite end of the machine.
  • The gearbox housing has threaded holes for attaching standard handles. Using the corners and these holes, the angle grinder must be attached to the moving part of the machine.
  • The back of the body is attached to the board with a clamp. The blade guard can be used with any power tool of suitable size.
  • Closer to the vertical support, you need to fix the stop angle. It should be located strictly perpendicular to the plane of the disk, both in vertical and horizontal directions.

The spring at the rear end of the bar serves to return the miter saw to its original position after the end of the cut. The horizontal table should have a transverse groove into which the disk enters when cutting the board. The diameter of the disc is chosen based on the width of the boards. So trimming can be done in one go. The main thing is that the inner hole of the disc must coincide with the mount on the axis of the gearbox.

When working on such a machine, it should be borne in mind that the drive power is not designed for a large load. Therefore, the rotating disc must be brought smoothly to the surface of the part being cut, the cut should be made without strong pressure.

Electric hand saw

A hand-held circular saw electric from an angle grinder is obtained by replacing a standard cutting disc with a disc for wood.

True, this option is suitable for short cuts in sheet materials or for cutting thin strips. With a long cut or on thick bars, there is a danger of the disc skewing, jamming it. It will be much easier to hold the saw if the handle is not positioned perpendicular to the axis of the tool, but is made a continuation of the body.

It is not recommended to remove the protective cover, as it will protect against the ingress of sawdust into the face.

Craftsmen also make a hand chain saw from an angle grinder. True, such a tool is dangerous for the user: the absence of a chain stopper can lead to unpredictable consequences. In addition, the chain is not lubricated, which leads to its rapid wear.

Circular saw from a conventional angle grinder

It is too expensive to have an entire range of electric tools at home. For example, a circular at home is rarely required. Sawing boards can be done with an upgraded angle grinder.

The nuances of using a homemade circular

It should not be overlooked that the angle grinder, by its main purpose, is an angle grinder. Therefore, using it as a homemade circular saw, you need to pay attention to the nuances.

  • Duration of continuous cutting should not exceed 15-20 minutes in order to avoid overheating of the motor.
  • The standard protection on the blade is in no way suitable for a circular saw. The protective cover can be used from a real circular or made by yourself.

It should be remembered that the rotation speed of the grinder can be more than 10,000 rpm. this is several times higher than the speed of woodworking machines. At this speed, the wood begins to smoke. In addition to an unpleasant odor, fire is possible.
