Can an angle grinder safely cut wood?

There is an angle grinder in almost every home, it is difficult to imagine carrying out many types of repair work without it. This multifunctional tool can cut various materials: brick, concrete, metal, porcelain stoneware, etc. The question of whether an angle grinder can cut wood is a matter of controversy.

The device and capabilities of the angle grinder

Arranged angle grinder (angle grinder) is quite simple. The electric motor, by means of a bevel gear, transmits rotation to the shaft, on which replaceable nozzles are fixed. The area of use of the angle grinder is extremely wide. It is used for cutting, stripping, roughing, grinding and sharpening. The type of work performed is determined by the functionality of the removable disks. Each angle grinder accessory has its own purpose.

Such a tool is used during construction work, in mechanical and repair shops, during rescue work and in other areas of activity. an angle grinder is indispensable both in everyday life and in production. We also recommend it

Cutting wood with an angle grinder

In the absence of special equipment for working with wood, it is allowed to cut wood with an angle grinder. But the thickness of the material cut by an angle grinder should not be more than 4 cm.Use special cutting discs and wood cutters recommended for working with an angle grinder.

Hold the cutting tool perpendicular to the work surface. If it is possible to adjust the speed of the angle grinder, set the minimum value. The recommended maximum values must not be exceeded (the corresponding marking is on the disc). When cutting at high speeds, the wood starts to burn, a large amount of smoke is emitted.

It is not recommended to use the button lock during operation in order to be able to turn off the device and minimize possible damage. In order for the tool not to jerk at the end of the cut, experts advise first to file the workpiece along the edges, and only then cut it.

Basic safety instructions

Before cutting wood with an angle grinder, you must familiarize yourself with the safety rules. The main of these rules are as follows:

Be sure to use personal protective equipment (protective plastic glasses, fabric gloves), work in overalls.
Never use defective discs.
It is recommended to hold the angle grinder firmly with 2 hands.
Always make sure that the power cord is not close to the rotating disc.
Place the angle grinder only after the cutting element has come to a complete stop.
Do not remove the protective cover.
Not working while intoxicated.

Do not use accessories that are not intended for work with an angle grinder. You should not use cutting equipment for circular saw blades for the following objective reasons:

An angle grinder has a higher rotational speed than a circular saw. The disc is designed for lower revolutions, therefore, at high speed, it can crack and fly apart. Flying fragments can be harmful to health.
The wood has a more viscous texture and inclusions in the form of knots, because of this, the teeth enter the material unevenly. If the disc gets stuck, the tool could be pulled out of the hand, resulting in serious injury.
Due to uneven loads, the equipment overheats and a failure is possible.

Sawing wood with an angle grinder

Sawing wood with an angle grinder is relatively safe. It provides for a rigid attachment of the cutting equipment to a bed with guide elements. This will be a stationary sawing equipment in which the angle grinder is securely fixed. A self-made machine works on the principle of circular saws, where the processed material is fed along the guides.

You can cut firewood with an angle grinder, but you need to use the devices necessary to ensure safety. A jigsaw, circular saw, hand tools are more suitable for working with wood.

Discs for wood on an angle grinder

The angle grinder is used for working with hard materials and is not a specialized tool for processing wood. But you can use it for these purposes, although you will have to comply with some conditions. It is strongly discouraged to use the standard equipment, because It is not safe.

The industry produces a number of specialized wood discs recommended for the angle grinder:

Cut-off discs have specially shaped teeth and reamers located on the cutting part to prevent jamming of the tool.
Chain discs are designed for modeling, milling and stripping wood. They are a disc made of high-alloy steel, on the outer edge of which a chain from a chainsaw is installed.
Special flap sanding attachments are designed for smoothing irregularities and cleaning. Such a nozzle consists of several layers of sandpaper, stacked radially one on top of the other so that they overlap.
The disk plane is used for rough processing of wood blanks, for example, in the construction of a log house. This attachment replaces the carpenter’s ax.
Wood cutters allow for rough milling work.
End discs are used to level the end surface.
Sanding disc for wood with interchangeable sanding discs of various grain sizes.

Grinding and polishing

For grinding and polishing wood products, a tool is better than an angle grinder. it has good performance and is capable of providing high quality work performed. With an angle grinder, you can perform the entire cycle of woodworking operations: from roughing to finishing polishing.

To carry out these works, special grinding attachments are used. The quality of the product depends on how correctly the wheel is selected for the angle grinder. These attachments differ in shape, material and purpose.

For roughing (roughing), the following types of nozzles are used:

a roughing circle. a steel disk on which pieces of metal wire are soldered;
cord brush. a disc with a wire pile (there are different hardness);
end disc.

For polishing and final grinding of the nozzle, other nozzles are used:

petal;
grinding;
cup. brushes made of special abrasive nylon.

The angle grinder is not suitable for sawing or cutting wood. The use of an angle grinder for these works is not recommended, but under certain conditions, a small amount of work is allowed.

The dangers of working with wood

The main difference between an angle grinder and the same circular saw or electric jigsaw is the absence of a stopper. This means that the cut is carried out by weight. without resting on a solid surface. As a result, the disc can “walk” a lot, and this will lead to the wheel getting stuck and knocking the angle grinder out of the hands of the master.

A critical situation always occurs suddenly. The most dangerous thing is that you cannot predict the angle of throwing the tool.

Tungsten Carbide

A robust all-rounder that handles all materials and does not knock out, even at high rpms. The price often bites.

Milling cutter or chain disc

This option is quite expensive, but it has a special mechanism in its structure that will prevent the tool from being knocked out of the hands. It can be rotated when biting into wood. Its diameter is not less than 23 cm.

Saw blade with few teeth

Aerated concrete blocks are usually sawn in such a circle. Suitable for wood as well. Manufacturers apply a marking on a special sticker. From it you can find out the maximum number of revolutions and adjust the operation of the device.

Grinding attachments

The machine is designed for grinding, so there will be no problem with the operation. Just install the attachment holder and the abrasive wheel. The grain size is chosen to be of the appropriate size.

Can an angle grinder cut wood

Experts unequivocally answer the question. no, this is absolutely impossible to do. The material is too uneven. It is soft at first, but can easily be replaced by a thick knot. Once on it, the disc will not scatter, as a circle on metal would do.

The attachment will lead, tearing the tool out of the hands of the master. A dangerous condition, given that the circle at this moment continues to spin with great speed.

Milling with an angle grinder

Another operation that many experienced craftsmen successfully perform with this tool is milling. Unlike a router, you will not be able to perform really high-quality processing. However, making a groove, as well as cutting a small part. it will turn out to be quite tolerable.

Again, this operation is dangerous. I have already written recommendations for general action using this tool, so follow them. An angle grinder needs a thick and high quality cutter. Immediately dismiss the possibility of using homemade nozzles, give your choice to an old brand, insured against chips and breaks.

Even with all the tips, a beginner alone should not start milling without the supervision of a more experienced craftsman. As mentioned above, accidents constantly occur with the masters of their craft, given the instability of the tool.

Wood sanding attachments

Since the machine is called a grinding machine, then it should not have any problems with grinding. For this purpose, in working with wood, use a nozzle-holder, on which an abrasive wheel with a grain from large to fine is molded.

Saw blade with few teeth

Please note that on the surface of such a disc, the manufacturer applies information about the maximum number of permissible revolutions.

Large tooth spacing makes woodworking safer

Such discs, in addition to wood, do a good job with aerated concrete blocks.

Grinding: attachments and process

Sanding pads are discs that are produced by layering several different coatings. To improve the abrasion characteristics of the treated surface, the initial layer is made of rubber, sometimes it is replaced with hard plastic. The layer of the second level of the nozzle allows to ensure the adherence of the plane of the working part to the surface to be grinded; it is made of foam rubber. The main, working layer is a sheet of sandpaper.

The use of sanding pads allows you to work efficiently with already painted surfaces. Rough polishing of the untreated surface is also possible.

Flap-type discs are suitable for the same purposes, only in rough grinding it turns out faster. A disc of this type is sandpaper petals attached to the working surface of the disc.

To remove paint, it is best to take special devices with peeling functions. Steel cup, with attached steel fibers made of hard wire, excellent abrasion, additionally sanding wood.

What can you do with an angle grinder?

Angle grinder, in common people an angle grinder, is capable of performing many operations.

The design of the angle grinder makes it a rather powerful tool: the basis is an electric motor from 600 to 2700 W with a gearbox, shaft and replaceable nozzles

The more powerful the engine, the higher the professional class of the device. For ease of use, high-quality models are equipped with handles that allow you to securely fix the tool during operation. Household models operate on a regular network. A professional tool requires a three-phase power supply at 380 V.

angle grinder can work with different materials: concrete, metal, wood, brick and ceramics, stone, plastics.

The versatility of this tool is due to the use of a variety of attachments, each of which is designed for its own type of operation.

For the convenience of work, the angle grinder can be permanently mounted with special fasteners on the working surface. Some models are equipped with adjustable disc rotation speed.

Can an angle grinder cut wood

If you are trying to understand whether it is possible to saw wood with an angle grinder, then the answer to this question is unequivocal: you can. But many will not do this, tk. people get too many injuries precisely from using an angle grinder as a saw for wood, which is correctly called an angle grinder.

First of all, this is caused by a sufficiently high speed of its rotation, for which most saw blades are simply not designed. But who pays attention to this when it is necessary to do the work, and there seems to be a suitable tool at hand, and a compensator ring of the required size is also applied to the saw blade for wood. over, the protective casing is removed for the convenience of work, which is absolutely impossible to do.

But, we will not talk about injuries, but let’s talk about what and how you can process (including sawing) a tree using an angle grinder, but first about the difficulties of working with an angle grinder with wood.

What is the danger of working with an angle grinder

Any power tool is potentially hazardous, especially to those who neglect safety and protection measures during work. What’s dangerous about an angle grinder:

angle grinder attachments rotate at a very high speed: more than 10 thousand revolutions per minute;
most of the rotating disc is not protected by a cover;
when cutting the material, small fragments and sawdust are often formed, which fly away at high speed to the sides;
a powerful device is quite difficult to hold in hand, especially if the material for cutting has a complex structure.

When choosing cutting wheels, remember that they are quite fragile and can crack and fly apart during operation.

Advice! When choosing attachments for an angle grinder, pay attention to their condition: they should not have any defects. The slightest unevenness or chipping can lead to sudden destruction of the material during operation.

The slightest misalignment leads to jamming of the nozzle. Because of this, a powerful jerk occurs during work, which can knock the tool out of the hands.

Advice! If you do not have experience with an angle grinder, do not seek to acquire a powerful professional model. Better take a household appliance with a disc diameter of up to 125 mm.

For the convenience of work, the angle grinder can be permanently mounted with special fasteners on the working surface. Some models are equipped with adjustable disc rotation speed.

Tungsten Carbide Discs

Such attachments have appeared relatively recently and have already become very popular. The reason is that they easily deal with small metal inclusions at high revs.

This is perhaps the only option for a nozzle that will definitely cope with sawing, without any unpleasant nuances.

For your information! Rotarex discs are in great demand, which can be used for sawing wood.

In addition to the actual discs for wood processing, there are other attachments for the angle grinder.

Chain disc or cutter

This version of the nozzle has a device that allows you to turn it even when biting the chain mechanism, eliminating the likelihood of a sudden jerk.

With the help of such a cutter, you can make notches in a log, remove bark, cut out complex relief on the surface.

How To Cut Wood With Angle Grinder. NOT toothed disc.

In principle, it is possible to saw with a chain disk if it has a diameter of 23 cm, only such a nozzle will cost a lot.

Why is it difficult to work wood with an angle grinder?

First of all, it should be noted that the high speed of rotation of the disc distinguishes the angle grinder from the circular saw. And even the presence of a compensating ring that comes with the disc does not completely solve the problem. But if your angle grinder has a speed control, then this partly makes the task easier.

You can adjust the tool so that its speed matches the speed of the circular, this will also reduce the risk of injury to the process.

But the main difficulty lies not in this, but in the structure of the wood itself, which is often heterogeneous and knotty. In addition to multidirectional fibers, there is resin in the tree, there may be pellets or ingrown wire, which you will not immediately notice. In general, wood is an unpredictable material. During work, you may encounter an unexpected obstacle, and, as a result, a jerk that can knock the tool out of your hands and direct it along a dangerous vector.

If the disc meets a piece of metal, a tooth can fly out of it, which, like a bullet, can also rush in an unpredictable direction. You are lucky if he comes across a protective cover on his way.

If you are thinking of sawing wood in the area with an angle grinder, you will have to keep it in a horizontal position. This will make the grip uncomfortable and increase the risk of injury.

Important! It is strongly not recommended to cut wood with a tool that does not have a speed control and attachments that are not intended for this purpose.

Can I cut wood with an angle grinder? You can, but right

What attachments can be used to work with wood

As already mentioned, not every attachment is suitable for this task. Don’t risk using wilds that are not designed for woodworking. Possible attachment options are shown below.

CAN ANGLE GRINDERS CUT WOOD?? (Tricks TipsCutting Wood With Grinders)

What disc for an angle grinder to cut wood?

As already noted, on the construction equipment market, there is a special tooling for angle grinders, with which it is planned to process wood blanks. Usually these are adaptive discs with reamers in the cutting area and a special shape of the teeth. This design focuses on reducing the likelihood of a wedge. over, for wood, you can find both cutting and grinding wheels. Another option for an acceptable attachment for such purposes is chain equipment. But in working with it, one must take into account the wide grip of the cut, about 8-10 mm. A chain disc with an angle grinder can cut wood with a maximum depth of 125-230 mm. These are standard sizes for an angle grinder, but the workflow will have low vibration and no risk of the tool sticking out of the hand.

Cutting wood with an angle grinder

In the absence of special equipment for working with wood, it is allowed to cut wood with an angle grinder. But the thickness of the material cut by an angle grinder should not be more than 4 cm.Use special cutting discs and wood cutters recommended for working with an angle grinder.

Why do experts not recommend using an angle grinder for cutting wood?

Experts are unanimous in the opinion that special power tools should be used for processing wood, designed specifically for working with this type of material. If you use an angle grinder to cut the bars, then the master in the process of work may encounter the following problems:

During wood processing, the working disk will overheat, which directly affects its strength. If the corner is slightly beveled, the probability of a disc rupture increases significantly. Failure to follow this point can result in serious injury.
The teeth of the disc in the process of processing wood material often grab more raw materials, from which the tool can simply break out of the hands in working order. The result can be disastrous for the master.

As you can see, the main problem in working with an angle grinder for wood is the inability to provide adequate safety for yourself and others. Even experienced specialists cannot always guarantee a 100% good work result, the safety of the tool, protection from possible injuries.

angle grinder is a multifunctional tool. It can also come in handy when working with wood.

And why then you can saw with a hand-held circular saw?

Here the keyword is. support ! If we cut wood with a circular saw, then we rest the tool on the workpiece and simply push it forward along the intended mowing line. The tool disc does not lead to the right or left as the support prevents the disc from canting. In the case of, for example, a stationary circular machine, it is still easier, the disc is fed across the table and again, resting it on the table, we do not allow the workpiece to tilt to the right or left. In the case of an angle grinder, the disc has no support other than our unsteady hand.

That is, if we saw with a circular saw, then we push the tool with our shoulder against the material, if we work with an angle grinder, then we simply hold the tool “in the air” with the strength of our brushes (which in an emergency, most likely, will not be enough).

In addition, an angle grinder rotates much faster than a circular grinder, an angle grinder has an average linear rotation speed of 80 meters per second, and a circular saw this value is on average 60 meters per second.

Saw blade with few teeth

Please note that on the surface of such a disc, the manufacturer applies information about the maximum number of permissible revolutions.

Such discs, in addition to wood, do a good job with aerated concrete blocks.

Disadvantages of wood processing with an angle grinder

The main argument against using an angle grinder when working with wood is safety. There are certain ergonomic nuances associated with the inconvenient cutting direction, but specialists from such cutting tactics are often stopped by the risks of injury. Why is it dangerous to cut wood with an angle grinder? Compared to the same jigsaw or circular saw, the angle grinder does not have a stopper. a device that physically stops cutting when passing a critical point. In other words, when the seating zone or the center of the cutting blade approaches the surface of the workpiece, the likelihood of tool snagging and sticking out of the hand increases. This can happen out of the blue, as can the throwing direction of the angle grinder. The second nuance is associated with the nozzle itself. For example, it is strictly forbidden to use disks with soldered segments, as they can collapse during operation. But today manufacturers also produce special equipment for servicing soft building materials.
