What disc to cut wood angle grinder

How to cut wood 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 hazardous work. When sawing wood with an angle grinder, the surface will not be smooth as, for example, when using a circular saw, but these errors can be easily corrected, the surface can be sanded.

You need to be extremely careful when cutting wood with an angle grinder and a suitable disc designed specifically for sawing wood, but they are not very common on the market. The special disc 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: “Can an angle grinder cut wood with a disc for metal?” 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.

Sawing plywood angle grinder

To cut plywood with an angle grinder, wood discs are often used. Due to the large accumulation of dust, 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 an OSB angle grinder is safer and better 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.

Is it possible to saw 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.

Sawing wood 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, it is required 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.

Required tools and materials

Cutting ceramic tiles is a laborious process that requires maximum concentration. The difficulty is largely due to the fact that the tiles are made of durable material. Dust-free tiles can be cut and sawed down with a tile cutter, but such a tool is not cheap. This is nearly impossible with conventional cutters and saws, and the cut is likely to be uneven and unattractive. A regular angle grinder is best suited, the cutting wheel of which allows you to neatly cut tiles even at home.

Despite the fact that this process is relatively difficult, if you get the hang of it, it does not take much time and does not require much effort. An ordinary homeowner who has not dealt with such work can cope with this task and will be able to cut off even a “hog” without the help of a tile cutter.

You can cut tiles using the following tools:

  • special tile cutter;
  • diamond tools;
  • Angle Grinder.

For cutting ceramic tiles, those that have a diamond coating are suitable. Their use minimizes the formation of cracks and chips. It is forbidden to use discs used for metal work, as they will only damage the tile. Even if you manage to cut with the help of such a circle, it will be uneven and of poor quality. This is due to the sliding of the disc on the tile, due to which the presence of small cracks is inevitable. At the same time, when it comes to home surface finishing, you can ignore these damages, since they will surely disappear during subsequent processing.

In no case should you neglect safety measures, since the risk of harm is quite high.

Be sure to carry the following attributes with you:

  • glasses;
  • mask;
  • thick gloves.

Please note that the selected angle grinder or grinder must have a speed regulator, since many modern inexpensive tools do not have this function. Such models operate at the highest speed, which is why it is impossible to cut tiles with their help.

How To Cut Tile Angle Grinder?

When doing renovations, many homeowners find it necessary to cut ceramic tiles that can be done using an angle grinder. This tool allows you to do this work at a high level, with minimal risk of chips or cracks. In this article, we will show you how to cut ceramic tiles using an angle grinder.

We cut the tiles correctly

Using tiles for wall decoration, a situation will surely arise when you need to cut off part of the slab so that it fits into the remaining space. over, a similar procedure will be required regardless of which type of tile you choose. Cutting is required most often in cases where unique patterns on the walls are created or various decorative objects are formed using tiles.

If you have already prepared all the attributes you need for work, you can consider how the tile should be cut correctly. The angle grinder is an excellent helper in this matter, since with its help you can create not only straight cuts, but also curly cuts. Next, we will look at how to cut tiles in various ways.

A straight cut is as simple as possible:

  • First, you need to fix the tile on the plane so that it does not slide and ride on it.
  • The part of the tile that needs to be cut must remain in weight. the surface line will be the guideline for the notch mowing line;
  • You need to take an angle grinder so that you can see the cut line. If you hide it from yourself, you will not be able to make an even cut.
  • You need to direct and move the blade towards you, not away from yourself. This is the mistake many beginners make. Hold the tool firmly and level so that it does not move in different directions, otherwise the cut will be ugly. Holding the angle grinder crooked can damage the disc as it can fly off.

A round hole is made as follows:

  • Initially, you need to use a marker to draw the required hole. Draw on the glossy side of the tile.
  • Then you need to determine the center of the circle. This can be done using straight lines drawn crosswise.
  • Gently saw the tile from the inside in a circle until we go deeper.
  • It is necessary to turn the angle grinder so that the blade gradually fits into the outlined circle.
  • When the cut is deep enough, it is required to saw through the drawn cross along the drawn lines, after which you carefully take out the resulting 4 sectors of the circle.

You need to cut the tiles only on the front side, since this is the only way to get a cut without various defects. Consequently, all possible damage will be concentrated on the back of the tile, which will be hidden with tile adhesive.

It is best to measure and mark the tiles to be cut from the start.

To cut at a 45 degree angle, follow the instructions below:

  • It is important to note that cutting the tiles obliquely is more difficult than making a straight cut. However, this is much easier than creating curly elements. You need to start by doing.
  • the angle grinder must be turned so that the disc is located at the angle you need, while you must carefully drive the blade, removing excess, so that at the end an even angular cut is obtained.
  • Perfectness can be achieved by using ordinary sandpaper, which is best fixed on a bar.

Abrasive paper should be used for each element as this will help improve the appearance of the cut.

Important nuances

The angle grinder must be set at a low speed so that you can control and adjust its actions. When you have the ability to secure the tool, be sure to do so, as this will simplify your work. Once the angle grinder is secured, you only need to move the tile along the desired trajectory.

If there is no possibility of securing, then the floor is the best place to work. Be sure to put bars or lumber under the slab. It is important to note that a low speed should also be set due to the fact that this will exclude the discarding of the blade or disc upon contact with the surface.

Turning on the maximum speed will surely simplify the cutting process, but this increases the risk of damage to the tiles, which can simply fly to pieces. The easiest way to cut is the straight line cut, since even a beginner can handle this job. When it comes to rounding, then more effort will be required. If you have not previously encountered such work, then we recommend that you first try your skills on defective material.

You can protect the tiles from chips by using a special grinder or sandpaper. This work is not difficult, but it will significantly improve the quality of the cut. Thus, you can get rid of existing defects.

If you decide to choose a grinder for this work, and not sandpaper, then you need to work at the minimum speed.

Be sure to follow these guidelines:

  • you need to work in special clothes;
  • safety glasses are required;
  • it is recommended to use earplugs when working;
  • all used devices must be in good condition;
  • work can only be performed by adults who know the safety rules for using a cutting tool;
  • when wet processing, make sure that the sander does not get into the water, as this can lead to an electric shock;
  • you cannot process slices at maximum speed;
  • you need to work in a room with good ventilation.

To maintain your health, it is extremely important to follow these recommendations.

Difference of discs by arrangement of diamonds

Artificial diamonds are fixed in the working rim in a specific order. There are circles with their uniform distribution, when in any of the selected units of length or sector there is a uniform number of crystals.

But there are also circles in which diamonds are arranged with a certain period (the so-called sandwich). They are the most productive, providing the least force on the tool, the most effective cooling and an even distribution of force.

Sizes of diamond discs

The maximum cutting depth and, in some cases, the speed of work depends on the size of the disc.

The main diameters are 115, 125, 180 and 230 mm, which corresponds to the abrasive wheels for the angle grinder of the more common brands. On sale you can also find diamond discs with a diameter of 150, 300 and more mm. Huge diameters are installed on massive cutting machines. gas cutters, stationary cut-off machines, etc.

The most common disc bores can be 22.2 mm or 25.4 mm.

Buy only a disc of the size for which your instrument is intended.

Never place an oversized disc on an angle grinder that is designed to work with the smallest disc size after removing the protective guard. This is extremely unsafe, as the destruction of the iron disk can cause fatal damage to your own health. If you have such ideas, then look in the internet for a photo of the consequences of working with a diamond disc without a protective casing, and you will forever stop working without protection.

Grinding discs for metal

There are 2 types.

Flap disc

Abrasive type grinding disc.

Despite the apparent difference, the effectiveness of their work does not actually differ. But there are still differences. Hard bumps are removed with an abrasive wheel. Such as weld fusion, large burrs when cutting or chopping the alloy. You can create tool sharpening. With certain abilities, you can grind smooth surfaces, but this takes a lot of time and the cost of error is very high, with careless movement you can make a cut.

Flap discs are smoother and more forgiving.

But with their help it is difficult to remove hard protrusions. But you can perfectly polish the embossed surface.

Alloy Grinding The angle grinder is the second most popular application area after alloy cutting. No iron brush or sandpaper can match the speed and quality of an angle grinder and the right sanding disc.

Complex and consistent use of a pair of nozzles can give a result comparable to factory machining.
When grinding stainless steel or duralumin sheets, some home professionals manage to create patterns from the traces of the disk.

How to understand discs for an angle grinder for metal

For high-quality alloy cutting, it is not enough to choose an angle grinder, you also need to choose a good disc.

With different angle grinder attachments, you can cut, grind and polish the alloy, as well as almost everything else. In the midst of an abundance of alloy wheels for an angle grinder, making the right choice is sometimes difficult even for a professional.

To understand the types of consumables and the peculiarities of working with them, this article will help.

What is a saw blade for aluminum?

And “for aluminum” means for processing duralumin blanks! Everything is as easy as shelling pears! ” Simpler it is simpler, but not completely simple. Let’s take a closer look at this question.

Yes, indeed, the saw blade is designed to equip a circular saw. this is how a circular saw is also called. or for a circular saw.

And such a power tool is now available not only in production, but also in every “household man”, in the garage or in the country.

And, yes, with the help of it you can saw almost anything, if only the saw circle was well matched to it.

True, to purchase such a saw blade is somewhat more problematic than its “brother” in wood.

When buying a cut-off wheel for an angle grinder, first of all, you need to know what it is intended for sawing, the required cutting thickness, fit size and permissible diameter of the cutting wheel. In addition, due to the injury hazard of such work, attention should be paid to the manufacturers of this consumable. As for aluminum, you should keep in mind that it is soft and tough, capable of hammering the surface of the cut-off wheel in a matter of seconds, which significantly complicates the cutting process. And now, in order.

When choosing a cut-off wheel for working with non-ferrous alloys, you should pay attention to the face of the wheel.

It contains all the numerical and graphic designations required for the correct selection. This designation is in, with which the manufacturer advises to work, the size of the circle and the bore, as well as the shelf life, operational personality and the very allowed revolutions at which this consumable can work.

Shelf life

Basically, all manufacturers of cutting abrasive wheels mark their products, affixing the number of the month until which this “consumable” is good, and after a fraction. the year of manufacture.

Angle Grinder Wood Carving. Graff Speedcutter


For example, it looks like this: V01 / 2014, which translated into human language means: the circle is valid until January 2014. We remind you that in order to avoid injuries, it is not recommended to use expired products.

Cut-off wheel dimensions

All the dimensions you need are printed on the disc label. As a rule, they are designated as follows: 125×2, where 125 mm is the outer size of the disc, and 2 is its thickness. Today there are blades for cutting alloy, of different sizes and landing diameters, depending on the type of tool on which these “consumables” will be used.

It is not difficult to buy a cutting disc online on the website of Vira LLC, for any type of angle grinder.

Most often, it is quite simple to call the phone number indicated on the website and the transport company will deliver your chosen consumable in a matter of days.

We remind you that for the clearest, highest quality and safest sawing of aluminum, it is necessary to choose cutting discs with a width of about 1 mm. Such thin circles heat up the alloy less, thus there is no effect of “greasing” the abrasive with molten metal particles.

Important! Never install on your “angle grinder” a wheel with a larger diameter than recommended for a particular brand of angle grinder. It is extremely unsafe for your life and the health of people around you.

Almost all home craftsmen have a worldview that the thinner the cutting wheel, the easier it will break.

There is not even a grain of truth in this. All cutting discs are made using a reinforcing mesh, and some cutting discs for aluminum are made from a high-quality metal plate with abrasive substances applied to its surface. In addition, wheels with small abrasive particles are produced directly for aluminum, which prevents it from “greasing”.

I would also like to say a few words about the manufacturers of cutting wheels. Especially popular with experts are the aluminum wheels produced by the companies: Bosh, Berner, Kronenflex.

Also, almost all experts advise using DeWalt cutting wheels for cutting aluminum.

Why are we so sure of this? So what we pay them to do!

Dural and AMG cut normally, but this one is softer than AMG and a disc with a large abrasive quickly clogs up, plus it bites and the angle grinder tries to get out of hand. The angle grinder does not jump with fine abrasive discs, but the work is extremely slow. If there are discs for cutting aluminum directly, how are they marked?

Ordinary cutting discs, even for stainless steel, cannot be handled with such a task in any way, despite the fact that they are designed for the most fluid. After about half of the thickness had passed, the disc got hammered completely, the aluminum got hot and began to jam. The temporary solution was as follows: put the thickest 1.6mm Modeco disc, slightly widen the incision, after which things went more fun.

The conclusions were made as follows: aluminum cannot be cut at high speeds, otherwise it floats like plasticine.

Overheating is also the main thing. I think it would be much easier if it was possible to constantly water the leaf with water.

True, the manufacturer writes that these discs are for a miter saw, how will they behave on an angle grinder? I think, in order to avoid the flying show, the angle grinder should be fixed in the rack.

We will probably give up cutting an angle grinder. There is a stone cutting machine. I moved my brains so much that it is better suited for saber purposes, and nothing needs to be fixed. True, his engine burned out, but dvigun is a real deal.
P.S. adianon, don’t you remember the brand of disks? Or at least the manufacturer?

How to choose a diamond blade for your angle grinder

When choosing a diamond blade, you need to pay attention to the type. for which the disk is intended, by its size, landing diameter and disk rotation speed.
