How to make a saw for wood from an angle grinder
How to cut wood with an angle grinder
The angle grinder, originally designed for metal working processes, has so many different uses with different types of materials, and even wood is no exception. An angle grinder can be used for woodworking, but you need to be extremely careful and be aware of the high risk of dangers of work. When sawing wood with an angle grinder, the surface will not be as smooth as, for example, when using a circular saw, but these errors can be easily corrected, the surface can be sanded.
It is necessary to be extremely careful when cutting wood with an angle grinder and with an appropriate disc designed specifically for sawing wood, but they are not very common on the market. A special blade for working with wood material has teeth that increase the size of the cut. When working on wood, the thickness of the wood should not exceed 4 centimeters.
It is forbidden to work with circles for a circular saw, as the speed of revolutions per minute differs significantly. It is not recommended to use discs with coarse teeth, since there is a high probability of the teeth catching on the material, which will lead to the wheel jamming. The likelihood of snatching the tool out of hand in this situation instantly increases. If possible, set a lower number of revolutions.
The question is often asked: “Is it possible to saw wood with a disc for metal with an angle grinder?” Of course you can, but not recommended. The wood will simply begin to smoke, an unpleasant odor will appear. It is better to use specially designated discs for this.
Is it possible to cut wood with a diamond blade?
Diamond discs are used most often for working with granite, tiles and ceramics. For wood, it is better to use discs with teeth. When cutting wood with a diamond blade, the material will smoke and the tool will heat up quickly, which will take time to cool down. Therefore, it is best to use discs as intended for specific materials.

In this article, we will show you how to cut wood with an angle grinder.
Sawing a tree with an angle grinder
Compliance with safety rules is the most important rule and an appropriate marked disc for working with wood will ensure your work is perfect. When we cut firewood with an angle grinder, for a safe cut, we need to fix the angle grinder according to the principle of a circular saw so that the angle grinder does not bounce under our feet. Such work is very unsafe, therefore, if there is an alternative replaced, namely a jigsaw, the same hand tool, or a circular saw, it is better to use them.
Pruning trees with an angle grinder also requires special care and it is worth remembering that small branches with a suitable disc can be sawed off for an aesthetic appearance, but thicker volumes of work should absolutely not be done on wood, especially on weight.
Sawing plywood with an angle grinder
To cut plywood with an angle grinder, wood discs are often used. Due to the large accumulation of dust, you need to work in a well-ventilated area so as not to breathe burning odors. Sawing is best done along the pre-marked mowing line, pay attention before the end of the process so that the circle does not get jammed by the sawn-off part of the sheet.
Cutting OSB with an angle grinder is safer and more efficient with the right blade. The ideal disc would be the so-called three-tooth saw blade for wood, which is designed to work at high speeds. It will be a plus if the angle grinder has a speed controller.

Materials and tools used by the author:
List of materials:. old hacksaw;. piece of iron pipe;. sheet metal;. bolts and nuts;. one bearing;. paint for metal.
Step one. The first thing we need is a hacksaw, an old tool will do, but it will need to be sharpened. We remove the handle from the hacksaw, it is not needed. If desired, the hacksaw blade can be significantly shortened, since its stroke will be small.
Step four. Let’s prepare the hacksaw tightly, we need to drill a hole in it of such a diameter so that the bearing mounted on the shaft of the angle grinder can fit in it. The author drilled the hole on a drilling machine with a step drill.
Next, the hole needs to be ovalized so that the canvas moves in only one direction. Here files and a drill will come to our aid.
Step five. FrameAlmost all the details are ready, it remains to make the frame, here we need sheet metal. We cut out two plates and drill in one hole along the diameter of the clamp, weld this part to the clamp, this will be the base.
Also, in both plates, you need to drill holes for bolts that will hold the plates together. Bolts need to be welded to the base.
In the end, it remains to modify the hacksaw blade, we drill 4 holes in it in those places where the connecting bolts are. The holes must be bored with a file to an oval shape. As a result, the bolts will serve as guides that will hold the hacksaw blade.
Step six. Painting and assembly We paint all the details so that the homemade product does not rust and looks good. Well, then everything can be assembled, we install the base and the eccentric, well, then it remains to put the hacksaw blade and the upper part of the frame. The homemade product is ready, you can test it, but do not forget to lubricate everything well! The tool cuts beams, and even a log. Of course, the performance of the saw is not very high, since the stroke of the hacksaw is too small.
In general, the homemade product deserves attention, since everything is done quite simply. This completes the project, I hope you liked it and found new ideas for yourself. Good luck and creative inspiration if you decide to do this again. Do not forget to share your ideas and homemade products with us!
A circular saw is useful, and sometimes a must for the DIYer. The owners of private or country houses are constantly renovating, creating, rebuilding something. The main material is wood or its derivatives. plywood or chipboard, which must be cut, cut into blanks or parts.
The purchase of a manual circular electric saw requires costs, and the creation of a stationary circular with your own hands is impossible without a working shaft and an electric motor. A good way out of the situation would be to use an angle grinder as a drive mechanism, which is equipped with a seat for a saw blade and has its own electric motor. You only need to create external equipment that turns a regular angle grinder into a kind of circular (circular) saw.
Safety engineering
From a safety standpoint, the idea of using an angle grinder as a saw is very dangerous and undesirable. Too high rotational speed of the disk, unreliable fastening of the tool, inability to install high-quality protection. all these factors unanimously demand to abandon the idea and turn to other options.
However, if a decision is made, the following requirements must be considered:
- stability, immobility of the bed;
- rigid fastening of the tool, the impossibility of vibration or movement of the angle grinder;
- using only high-speed saw blades.
In addition, it is necessary to follow the general rules for working on a circular machine, the main of which are:
- the presence of hanging ties, sleeves, ends of clothes is excluded;
- it is forbidden to move workpieces with bare hands in the immediate vicinity of the saw blade;
- if the workpiece is jammed, immediately turn off the machine and eliminate the problem;
- start work only after reaching full rotation speed;
- it is forbidden to brake the disc after turning it off with hands or foreign objects, you must wait for an independent stop.
Compliance with safety rules is a prerequisite for working with woodworking machines. They are considered the most traumatic group of industrial equipment, therefore, the safety rules cannot be ignored in any case.
Step. preparing the hacksaw blade
Marking is carried out in arbitrary sizes.
Determine the place of contact of the hacksaw blade with the bearing. Marking the center.
Using a compass, we make the primary marking for the bearing. 3-4 points from the center.
We apply the bearing and outline it with a marker.
The resulting hole must be flared along the vertical level of the saw blade.
The hole needs to be shaped into an oval. The dimensions of its diameters are roughly 1 to 1.3. To accurately determine the shape of the hole, you need to try on the canvas in place.
Necessary materials
To make a homemade machine, you will need:
- rectangular pipe, steel or aluminum corner;
- chipboard sheet, dense plywood 12-14 mm thick;
- bolts, nuts, washers;
- metal strips, plates, large-sized corner pieces;
- welding machine with electrodes;
- electric drill or drilling machine;
- angle grinder;
- saw blade;
- connecting wires, on / off button.
Depending on the capabilities and needs of the master, other materials or tools may be needed. It is impossible to provide a complete list of components, since the design of the machine may be complicated, additional elements or functions may be added.
Examples of drawings of a conventional machine, for a general understanding of the device:
Step. making an eccentric
This step will not be difficult.
Install a reinforced washer on the spindle of the angle grinder and put a bearing on top of it.
The center of rotation of the bearing will be shifted with a bolt. We mark unnecessary.
Having cut off the bolt, we place its shortened rod inside the bearing.
We put a second reinforced washer on top and tighten it with an M8 nut;
How to Make a Mini Table Saw from an Angle Grinder. | DIY
The eccentric is ready. You can proceed to the next stage.
Step. assembling the saw body
We form a bolted connection on the nozzle body
At this stage, you need to weld the cuffs (fastening) to one of the metal plates and form holes for fasteners.
We fix the workpiece in a vice, attach the fasteners and weld it to the plate. The bolts welded to the ring must be on top.
Mark 4 bolt holes in each plate.
Moving on to the next step.
What is required for manufacturing
To make an electric saw you will need:
- hacksaw for wood
- a small piece of pipe 1.5 inches
- bearing. inner diameter about 22 mm
- metal sheet 2 mm
- nut М8
- bolts and nuts М6
- reinforced washers М14
Construction of a homemade circular from an angle grinder
- Hand circular saw from an angle grinder;
- Stationary circular.
The first option involves the use of the tool as a hand-held electric saw with a slight modification. assembly and installation of a stop that limits the depth of penetration of the disc into the material and protects against jerks and sudden movements. It will not work to do with the usual installation of the saw blade as a cutting wheel. the slightest misalignment will cause jamming, a sharp jerk or other dangerous reaction of the tool, which can result in serious injuries.
The simplest way is to install a stop, which is a flat platform that slides over the surface of the workpiece. It is attached to the tool with clamps or bolted into the handle hole. Some craftsmen make a platform from metal corners located on both sides of the disc at a short distance (2-3 mm).
In any case, a hand-held circular saw from an angle grinder is too dangerous and does not allow good control of the cutting line due to the installed protection. In no case should you take it off, since sawdust flying into your face can cause injuries.
Attention! The standard protection that comes with an angle grinder is not suitable for use with a saw blade. Have to do it yourself.
Creating a stationary version with your own hands allows you to get a safer and more convenient sawing machine for wood, which has almost the full functionality of a conventional classic circular saw. The main element of such a machine is a table in which a slot is made for the disc. An angle grinder is attached to the bottom side. It becomes possible to install an adjustable stop that allows you to adjust the width of the cut strips. Depending on the possibilities and need, you can make a device for facing and cutting the same workpieces of a given length.
The rotational speed of the angle grinder shaft is three times higher than the maximum speed of a conventional saw blade, so it quickly dulls and wears out. To create a regular saw blade operation, some craftsmen use a reduction gear. This allows for optimal rotation speed, reduces the risk of overheating and injury, but significantly complicates the design. Finding a ready-made gearbox is not easy and costly, so usually only an angle grinder is used.
The structure usually consists of the following components:
- bed (base);
- Desktop;
- motor and drive shaft (in our case, both elements are replaced by an angle grinder);
- stop designed to adjust the width of the cut parts;
- a platform sliding along longitudinal guides, allowing you to cut parts of a given length (optional, manufactured as required).
An example of a circular machine for wood
Important! If the saw blade is mounted directly on an angle grinder, without a reduction gear, only high-speed or carbide types that can withstand high heat have to be used.

How to make a “circular” on wood from an angle grinder with your own hands?
A circular saw is useful, and sometimes a must for the DIYer. The owners of private or country houses are constantly renovating, creating, rebuilding something. The main material is wood or its derivatives. plywood or chipboard, which must be cut, cut into blanks or parts.
The purchase of a manual circular electric saw requires costs, and the creation of a stationary circular with your own hands is impossible without a working shaft and an electric motor. A good way out of the situation would be to use an angle grinder as a drive mechanism, which is equipped with a seat for a saw blade and has its own electric motor. You only need to create external equipment that turns a regular angle grinder into a kind of circular (circular) saw.
Manufacturing
Consider the assembly procedure for a stationary saw machine, as the safest and most functional device. Step-by-step instruction:
- Preparatory part. It is necessary to create a working drawing, think over the design, clarify the dimensions and set of functions. This step is important and should not be ignored.
- Purchase and preparation of the necessary materials and tools.
- Assembling the table base. A base for the machine is assembled from a rectangular pipe (or corner). Sections of the required length are cut and welded together. It is necessary to ensure the stability and strength of the base. Alternatively, it can be made from wooden parts.
- A chipboard or plywood sheet is installed on the surface of the base, which will serve as a desktop. A slot is made in it for a saw blade.
- An angle grinder is attached to the work table from below using curved metal plates. Holes for screwing in handles are used. Depressions are made on the surface of the table so that the bolt heads do not interfere with the movement of the material.
- For the convenience and safety of turning on and off the machine, it is recommended to bring the wires from the start button of the tool to the side edge of the desktop, for which a piece of a corner or a bent metal plate is used. The button must be located as conveniently as possible so that there is a possibility of emergency shutdown of the circular from any position.
- The sliding stop, which allows you to adjust the width of the cut parts, can be made of various materials. Both the simplest devices, like a bar fixed with clamps, and more complex structures are used. There are a lot of options, but the choice is due to the needs of the owner and the nature of the work ahead.
The creation of additional devices requires the development of some experience and skill in using the machine. The specific design of the angle grinder allows you to work for about 15-20 minutes, after which a break is required for cooling. Given this circumstance, it is not necessary to count on a wide range of functionality.
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.
Step. final assembly
After making sure that the rotation of the eccentric is stable, you can finally assemble the attachment for the angle grinder. This is done with two nuts for each hole.
For appearance, the product can be dyed. Before assembly, you need to thicken the inner parts of the plate with lithol.
Step. making a case for a hacksaw
The body will consist of 2 steel plates. Their dimensions are arbitrary, but should not be less than 2 diameters of the bearing used.
We specify the outer diameter of the bearing and divide it in half on a caliper.
From the center of the plates, we make control points using a barbell, apply a bearing and outline it.
Drill holes on a drilling machine.
The holes in the plates can be punched out. To do this, use a drill with small drills and a chisel. The geometry is adjusted with a round file.
What is required for manufacturing
To make an electric saw you will need:
- hacksaw for wood
- a small piece of pipe 1.5 inches
- bearing. inner diameter about 22 mm
- metal sheet 2 mm
- nut М8
- bolts and nuts М6
- reinforced washers М14
- welding inverter
- angle grinder
- vice
- drilling machine or drill
Angle grinder electric saw test
The tests were successful. This saw is surprisingly good at sawing small logs in a couple of minutes.
Step. making an eccentric
This step will not be difficult.
Install a reinforced washer on the spindle of the angle grinder and put a bearing on top of it.
The center of rotation of the bearing will be shifted with a bolt. We mark unnecessary.
Having cut off the bolt, we place its shortened rod inside the bearing.
We put a second reinforced washer on top and tighten it with an M8 nut;
The eccentric is ready. You can proceed to the next stage.
Step. make the mount
At this stage, the workpiece from the pipe will need to be cut in half.
We measure the length of the seat for attaching the nozzle.
Using a compass, draw a transverse marking.
Awesome idea with Angle Grinder! And so it was possible
We circle it with a marker and make markings for the cut, which is needed to fix the mount on an angle grinder.
We make a cut on the markings, incl. transverse.
Weld two bolts on the propylene fixing ring to fix the fastening.
We put the mount on the angle grinder, and fix.
Step. assembling the saw body
We form a bolted connection on the nozzle body
At this stage, you need to weld the cuffs (fastening) to one of the metal plates and form holes for fasteners.
We fix the workpiece in a vice, attach the fasteners and weld it to the plate. The bolts welded to the ring must be on top.
Mark 4 bolt holes in each plate.
Moving on to the next step.
Making an electric hacksaw
Homemade electric hacksaw from an angle grinder
When working with an angle grinder, torque is used. For a hacksaw, we need translational movements. We will transform the rotation using an eccentric.
Saw blades for wood
electric saw from an angle grinder and a hand saw for wood
In this review, from an old hand saw for wood and a small angle grinder (angle grinder), the author decided to make an electric saw with his own hands.
It is difficult to call this homemade product an alternative to a jigsaw, but the author still decided to bring his idea to life.
Well, let’s see what happens in the end. So, to make a homemade electric saw, you will need: an angle grinder, a hand saw, a bearing, two metal plates, a round pipe.
From a piece of a round pipe and a bolt with nuts, the author makes a clamp, which is then put on an angle grinder.
The main stages of work
The author removes the handle from the hand saw, and then drills a hole in the canvas for the bearing.
Next, the master cuts off two identical pieces of a metal plate, makes markings and drills holes in them. It is convenient to use a stepped drill for this.
A homemade round pipe clamp will need to be welded to one of the metal plates.
We put a bearing on the shaft of the angle grinder gearbox. The master inserts a piece of stud between the inner bearing race and the shaft. It turned out to be a kind of eccentric. We put on a washer on top and fix it with a nut.
The hole in the blade for the bearing must be made in the form of an ellipse.
Then, four mounting holes must be drilled in the hand saw blade and two plates. We attach all the elements to an angle grinder.
For details on how the author makes an electric saw from a hand saw for wood and an angle grinder, see the video on the website.
