What to cut slate. a review of tools and cutting methods
, then the answer to the myth is unequivocal: there is an option. How to cut wood with an angle grinder with an angle grinder has shown a little how. But they probably won’t do it, t.к. Too many people get hurt just from using an angle grinder as a wood saw, which is properly referred to as an angle grinder.
Initially, this is due to its infinite rotation speed, which most saw blades are simply not designed for. Who pays attention to this case, when it is necessary to perform work, not under the hands of course the appropriate tool, and to the saw disk on wood in addition the ring-compensator of the necessary size is enclosed. Is it possible to cut wood with an angle grinder, how to do it. Also, the chain saw’s protective hood is removed for convenient operation, which should not be done categorically.
However, we will not talk about the injuries here, but let’s talk about what is not the most processed (in t.ч. saw) wood using an angle grinder, alas before. about the complexities of working with wood with an angle grinder.
The principle of operation of the angle grinder
To understand whether you can angle grinder to cut wood or not, to begin with let’s understand how this tool works. Angle grinder is a power tool that is used for processing, grinding and cutting stone, granite, various types of metal, cement surfaces and other. It consists of several parts:
- body (often cylindrical in shape).
- Protective guard to ensure the safety of the craftsman at work.
- Gear case.
- safety sleeve.
- Clamping nuts for discs.
- On and off pushbuttons, for disc replacement.
Different models of angle grinders may differ depending on the manufacturer and model, which in most cases are small. Due to the variety of attachments the tool is considered a versatile tool.
The nuances of working with an angle grinder on wood
Professionals rarely use the angle grinder specifically to work with wood, there are special devices and tools for this purpose. belt sander, electric saw, jigsaw. But in everyday life, if there is a need to perform woodworking works, to buy a whole set of expensive tools is not reasonable, then the help comes an angle grinder with an attachment for wood sanding.
angle grinder is not the most popular tool for sawing wood, because it is a material with a fibrous structure. With insufficient fixation and the slightest fluctuation and change of angle of incision, the fibers are uplifted, delaminated, formed chips, defects and dispersion of sawdust and chips.
The cutting attachment is justified only if the angle grinder is fixed as firmly as possible on the table for sawing. With the angle grinder you can make only a rough, not precise cut, as it is impossible to organize observance of all conditions for precise work. rigidly fix the material, tools and see the place of cutting.
Warning! Never cut wood with abrasive or diamond tools, it can cause breaking of the disk and overheating of the tool.
Sanding and polishing
The angle grinder is excellent for sanding. Work is carried out according to the following algorithm:
- Preliminary work. Initially coarse grinding is carried out with a roughing nozzle. It is in the form of a bowl with a twisted wire around the perimeter (similar in appearance to a brush with metal bristles). At this stage, old layers of paint are removed from the board.
- Preliminary (rough) grinding. Coating residue, protruding fibers and other imperfections are removed from the material surface. Work is carried out using grinding discs for angle grinder on wood. At this stage, the material is prepared for painting.
- Finishing (fine) sanding. Used for wood that will not be painted. To work uses an attachment for an angle grinder for grinding wood with a minimum grit abrasive. nulivki.
- Polishing. It is produced at low engine speed, and cloth circles are used as an abrasive.
In order to maximize the convenience and quality of all processes, it is necessary to correctly choose a suitable nozzle from the whole variety of their modifications.
Types of discs for woodworking
The construction tool market is expanding every year. What are the discs for the angle grinder, in more detail below:
Some discs are designed for sawing large and small parts of wood:
Used for roughing out wood. The nozzle is solid, one-piece. Mounted only on angle grinder with two handles.
Most efficient for wood. Suitable for stripping bark, trimming and sawing on tree branches, small boards (up to 4 cm). plywood, parquet, chipboard, fiberboard. Considered the safest. if the angle grinder jams, the chain stays in place, and the wheel makes idle speed.
No teeth, but segments around the circumference. Features high durability. not only cuts through wood, but also accidentally caught metalware.
The safest when working with wood. Suitable for both longitudinal and cross cuts, for cutting grooves in workpieces. Available in 3 and 4-tooth designs.
Depending on the number of teeth and material. Small toothed cutting discs are used for wood.
Such discs are used for the initial machining of wooden parts:
Used for roughing. Models are available in various grit sizes.
Used for smoothing various wooden surfaces. The nozzle smoothes the joint between two boards, and they meet in one plane.
Designed for cutting edges of wooden workpieces. Convenient for materials with diagonal (angular) cuts.
Use for roughing wood surfaces clean.
Another version of the disc for roughing out the surface of wood.
Performs more fine roughing work on wood.
Sanding and polishing discs
Discs for fine wood surfaces:
The surface consists of overlapping trapezoidal sandpaper segments. There are discs with different degrees of abrasiveness.
Used for polishing. Composed of densely compacted wool. There are coarse-coarse, half-coarse and fine-coarse versions.
The abrasive disc is glued on its working surface.
Intended to be glued onto the grinding disc, one side is made sticky. Differ in the size of the abrasive grain.
Important features of a cutting disc
Let’s understand how to choose a circular saw blade for wood, guided by the main parameters of the tool. After all, it is on them you can understand whether the nozzle is suitable for a particular task. And knowing even the small details, you can significantly improve the quality of your work.
Determines how wide the kerf will be. This parameter also indicates the strength of the cutting disc. The standard value is 3.2 mm. If you use a nozzle thinner than this indicator, then there is a high probability of overheating and failure. A disc that is too big will lead to higher material consumption. As craftsmen say. “transfer to shavings”.
Outer and inner diameter
Circular saw blade size for wood determines how deep you can plunge into the material to be worked. But when buying it is necessary to consider the inside diameter of the guard. Otherwise it would be impossible to fit too big a cutting disc on the circular saw.
Generally the sizes vary from 130 to 250 mm. But if the guard allows, you can find a disc with a larger outside diameter. But these numbers have no influence on cutting speed. The depth of penetration into the material is important. But the thicker the kerf, the hotter the blade will be.
Also the thickness of the power shaft on the circular saw has to be considered. So that the inner bore of the cutting wheel allows you to fit it tightly on the tool. The discs on the circular saw are installed with a diameter of 16 to 32 mm. And some models of discs have additional holes for a secure hold on the saw.
The number of teeth on the saw blade determines how clean the cut is. It varies from 10 to 90. And the highest quality of cut is possible with the maximum number of cutters. It will also be easy to work transversely in this case. And for longitudinal cuts it is better to use a disc with a small number of teeth.
Blades with 40 to 50 teeth are universal. They are easy to work in any direction. But here’s the trick. The more teeth, the slower the cutting speed. Fewer blades would do the job faster, but the quality of cut would suffer.
Angle of sharpening plays an important role. It is measured from the radius of the blade. When the slope is negative, facing the backside, it is easiest to make longitudinal cuts. Positive (toward the back) allows the disc to run over the material and grip it well. It facilitates cross-cutting of the workpiece.
- Universal (standard). from 5 to 15 degrees;
- Positive (aggressive). 15 to 20 degrees;
- negative, from 0 to.5 degrees.
But for a better choice, when in doubt how to solve a particular task, you need to pay attention to the configuration of the teeth. The flat pick is suitable for quick sawing in any longitudinal direction. Marked with FT.
If the cutters are alternately tilted in opposite directions, the saw will give a reasonably clean cut when working across the workpiece. Good for plywood, particleboard and composite boards. Marked with the letters ATB.
Combi version available, where 4 ATB cutters are replaced by one FT cutter. This arrangement allows for sawing wood in different directions and solving practically any problem. Marked with the word Combi.
An excellent result in sawing is obtained by successive alternation of the usual FT tooth and a higher but sharpened trapezoidal tooth. With such a disc you can safely saw not only any wood, but also non-ferrous metal. Teeth, in such a model, never break and do not catch sawdust.
Well, the cutters with a flat tip that ends in a chamfer (double angle) are not afraid of nails or hardened cement. This configuration is specifically designed for deck wood. But it is also successfully used in the cutting of building products.
First you need to think about the task at hand. That is, what kind of cut to make. longitudinal or transversal. The thickness of the wood block and its structure are then evaluated. Every type of wood requires a different rotational speed for the blade.
The optimum speed of the tool for sawing:
- Soft wood. 50 to 90 m/s;
- hardwood. 50 to 80 m/s;
- exotic wood. 80 to 85 m/s;
- Joinery wood and chipboard. 60 to 80 m/s;
- Fiberboard. 30 to 60 m/s;
- Laminate. from 40 to 60 m/s.
You can then look in your inventory for a suitable cutting wheel. And the marking of the tool is a great help in this. The disk carries all the necessary information. And a reliable and consumer-respecting manufacturer will mark it by laser in the form of pictograms.
The marking on the wood circular saw contains information about:
- the tool to be used (manual or stationary);
- the external diameter of the nozzle and the allowable fit;
- speed and direction of rotation;
- Material to which the tool is allowed to be applied;
- the width of the kerf to be obtained;
- The number of teeth;
- the service life of the bit.
Depending on the nature of the material and complexity of the operation, you can choose to work either a monolithic disc, or its counterpart with hard-alloy teeth. Some craftsmen take the easy way. Buy an expensive tool with an alternating flat cutter and a trapezoid-sharpened. Popularly such a disk is considered a universal one, for all occasions.

And this job, in t.ч. On wood, just for this tool. Only a small photo selection of accessories for the angle grinder for grinding. a testament to this.
- the easiest way to change grinding wheels is with the sticky base attachment, which holds interchangeable abrasive wheels with different grit or even polishing pile.
And instead of a conclusion. Can I use an angle grinder to cut wood?? Depends on what kind and with what. If you cut a thin dry twig, there are almost no restrictions, and if you have to do more serious work. see above.

Cutting wheels on an angle grinder for wood materials
The angle grinder combined with a wood cutting disc is a safety necessity. Work should be carried out in special protective clothing, and the workpiece to be sawed must be firmly fixed in a vise or clamp. It is important to hold the tool with both hands to eliminate the possibility of knocking it out of your hands. Preference should be given to the angle grinder, which has a speed regulator.
Manufacturers produce discs for bolgarkov on wood of four main types, about which we will learn in detail:
Circular or toothed. appeared the very first, but have not gained wide popularity due to possessing the effect of backfire.Blade has outward (face) arrangement of large teeth. Manufacturers produce cutting discs for wood on angle grinder with a maximum diameter of 180 mm. The teeth can be equipped with special carbide tips. These wheels are the most common, but they are the most dangerous tool in action. If possible, refrain from using it. It should be noted that you can use such discs on an angle grinder only if the tool is used as a stationary circular saw
Now it is not difficult to choose wood saw blades for the angle grinder, knowing what types they are. For housework, it is advisable to use a wood saw blade with a universal or tungsten carbide edge. They are not only considered effective, but also safe. Circles with a saw chain cost more, but they are also safe when cutting wood with an angle grinder. The most dangerous are discs with teeth. They are recommended only in situations where the angle grinder is made into a stationary circular saw.
Can an angle grinder saw wood, experience and theory
angle grinder. a tool that is sure to be found in the stock of every diligent owner. But not everything is simple with this equipment. The tool cuts through metal with ease, but is totally unsuitable for sawing wood. And the salvation will not become even a special discs, which are sold in the store. They are very dangerous and can cost the craftsman his life.
After all, we are talking about a universal tool for processing solid types of materials, but due to a combination of excellent functionality, ergonomics and performance, most masters try to use it even for work with soft workpieces in the form of wood. Let’s talk about how such a use of an angle grinder justifies itself.
The advantages of using an angle grinder for woodwork
This electric device has a powerful motor, which makes it possible to easily cope with different species, which are usually used in manufacturing and domestic construction. It is usually a question of working with beams, planks and even chipboard. Believe me, even the minimum power at 0.5-0.7 kW is sufficient for processing standard lumber. But then another question immediately arises: “Can the angle grinder cut wood or logs??”.
Much will depend on the typical size of the attachment, but for such a task, a chain saw is the best option. The angle grinder, in addition to its performance, was perfectly justified in terms of functionality. Today’s smaller models weigh very little, but have a large set of adjustment systems, technique controls and safety. The operator can even customize the machine himself for a specific cutting depth, number of revolutions, and the use of soft start and other features.
Disadvantages of wood processing with angle grinder
But the main argument against the use of an angle grinder when working with such a material as wood is safety. There are some ergonomic nuances, which are related to the inconvenience of the cutting direction, but it is the risk of injury that often stops specialists from such sawing tactics. Why sawing wood with an angle grinder is life-threatening? Compared with the same circular saw or electric jigsaw, angle grinder is not equipped with a stopper, or rather a device that will physically stop the sawing when passing the critical point.
In other words, when the landing zone or the center of the cutting disc will approach the surface of the workpiece, the probability of catching and departure of the device from the hands will increase. Believe me, these things happen unexpectedly, as does the direction of the angle grinder’s kickback. The second nuance is mostly related to the nozzle itself. For example, discs with soldered segments are strictly forbidden to use, because they can start to collapse right in the work. But at the moment, manufacturers have taken care of the release of special equipment for the maintenance of soft building materials.

In other words, when the seating area or the center of the cutting disc is close to the surface of the workpiece, the probability of snagging and flying out of the hands will increase. Believe me, these things happen unexpectedly, as well as the direction in which the angle grinder is thrown. The second nuance for the most part is associated with the nozzle itself. For example, it is categorically forbidden to use discs with dressable segments, because they can start to break right during the work. But at the moment, manufacturers have taken care of the release of special equipment for maintenance of soft building materials.
Preparing the tool and workpiece for sawing
The angle grinder should be carefully inspected and checked for proper function. You should assess the reliability of connections, electrical connections, the operation of safety systems and structural mechanisms. Separately check the hardness of the head‘s grip. If you plan to saw wood with an angle grinder indoors, it is not superfluous to prepare a construction vacuum cleaner. Modern models of angle grinders have a special nozzle for dust extraction. the connection to the vacuum cleaner will avoid contamination of the workplace with small chips. The workpiece itself should be dried, cleaned of foreign matter and dirt.
Start cutting with a soft start, if there is such a function. It is important to ensure operation at low RPM, if necessary building up torque as you go. Much in the tactics of changing the cutting parameters will depend on the hardness of the workpiece and its size. How to saw wood with an angle grinder, if you need an oblique cut? Unfortunately, a crooked cut is not permitted at all. The workpiece is cut only at right angles and no tilting is permitted, since tilting as such can be dangerous. Complex and irregularly shaped cuts are cut using different tools in the postprocessing process. After finishing work, you should wait for the disc to stop, turn off the machine and unplug the plug from the socket. The tool is then disassembled and cleaned of wood chips and dust.
Is it possible to saw with an angle grinder wood with a metal nozzle?
Most of these discs have a fine tooth, mandatorily supplemented with pobedite or diamond crumbs. This allows you to work with both metal and natural stone. For wood, such attachments are dangerous to use, but there are models of discs, the device of which is close to the optimal for the soft material cutters. So, to saw with an angle grinder wood with a metal disc is possible in cases where two conditions are met:
- The wheel has a sparse to medium tooth (a coarse tooth increases the risk of wedging).
- Segments or other inlays on the head surface are made of tungsten or carbide.
This design will minimize unwanted effects during work, but according to safety rules it is not enough to use an angle grinder in such operations either.
Details of use
Which disc to use for wood
To saw with an angle grinder wood, we have already noted. the construction equipment market presents a special tooling for angle grinders, which can process wooden workpieces. These are generally adapted discs with reamers in the cutting area and unusual tooth shapes. This design feature is intended to reduce the likelihood of wedging. Both sanding and cutting discs can be found for wood.
Another option of an acceptable attachment for such purposes would be the use of chain tooling. But when using it, you need to consider a wide kerf, around 0.8 to 1 cm. An angle grinder chain disk can be used to cut through wood up to a maximum of 12 cm in depth.5 to 23 cm. These are standard formats for an angle grinder, but the work process will be very different due to the low level of vibration waves and no risk of the tool flying out of your hands.
Is it possible to saw wood with an angle grinder with a metal nozzle??
Most of these discs (for metal) have fine teeth, and in the obligatory order everything is supplemented with diamond or even pobedite chips. It makes it possible to work with both natural stone and metal. It is dangerous to use such nozzles for wood, but there are models of discs that have a device that is almost ideal for soft material to cut.
Now, in order to saw with an angle grinder wood with a metal disc, make sure that two conditions are met:
- The wheel has a medium to sparse tooth (if coarse, but there will be an increased risk of wedging).
- The segments or other inlays on the surface of the bit are made of carbide or tungsten.
This design makes it possible to minimize undesirable effects during work, but according to safety rules, even this is not enough to use an angle grinder in such operations.
Preparing the angle grinder and the workpiece for cutting
Take into account the fact that the angle grinder must be well inspected and tested for function. Be sure to assess the reliability of connections, electrical connections, operation of the protective system and structural mechanisms. Separately, it is worth checking the degree of hardness of the grip nozzle, and if you plan to saw wood angle grinder indoors, it will not be superfluous to prepare in advance a construction vacuum cleaner (or shavings vacuum cleaner).
Modern models of grinders have a special nozzle for removing dust. the connection to the vacuum cleaner will make it possible to avoid contamination of the workplace with wood shavings. The workpiece itself must be well dried, cleaned of foreign matter, dirt.
Start with a soft start, if your angle grinder has such a function. It is important to work at low speed and, if necessary, to increase the torque later on. Much in the tactics of changing the parameters of the cut depends on what degree of hardness of the workpiece, as well as what its dimensions.
How to saw wood with an angle grinder if you need to make an oblique cut? Unfortunately, a curved cut is not allowed at all, and the workpiece should be cut exclusively at right angles, and any tilting will be excluded, as skewing as such can be dangerous. Complex operations of non-standard, including even shaped cuts are performed as part of the secondary processing of another tool, not an angle grinder. After the work is completed, you should wait for the disc to stop, turn off the machine and remove the plug from the socket. Next, the tool can be disassembled and cleaned of wood shavings, as well as dust.
When cutting slate material, a number of safety rules must be observed:
- Safely protect the respiratory organs, eyes and skin from slate dust.
- Use headphones if necessary to prevent noise exposure to the ears.
- Perform the work outside. so that there are no people, animals or objects on the side where the wind blows.
- When cutting slate with an angle grinder, a circular saw and an electric jigsaw, the safety rules for handling electromechanics must be observed.
Recommendation! To reduce dust and material brittleness soak the slate two to three hours before sawing. To do this, a strip of cloth soaked in water is laid along the marking line.
The need to saw slate arises in various domestic cases. from the installation and repair of roofing to the creation of home decorations. In this case, you need to take care of the proper organization of work. primarily in terms of the protection of workers from asbestos-cement dust with personal protective equipment and the surrounding area. The place where the cutting tool contacts the slate must be constantly wetted.
The following tools and methods are used to cut the material:
- An angle grinder with stone disk or diamond wheel.
- Manual circular saw.
- Electric jigsaw.
- A utility knife or a utility knife.
- Hacksaw for wood or metal.
Plain slate material is cut with the same power tool, but it breaks down better. In addition, when using any means of cutting material it is important to observe safety rules.
