How to Saw Tile Dust-Free Angle Grinder

2 ways to saw dust-free angle grinder?

Sawing with an angle grinder on concrete, brick, stone or tile produces a lot of dust. In this article, we will show you how to saw a dust-free angle grinder.

Dust not only pollutes the room or work area, but also has a detrimental effect on human health..

In addition, it is much more difficult and inconvenient to work in dust. it’s hard to breathe and you can’t see anything.

tile, dust-free, angle, grinder

There are two ways to do dust-free work..

The second way to connect the vacuum cleaner

This method consists in connecting a construction vacuum cleaner to an angle grinder using improvised means.

For this you will need:

polypropylene drainage branch with a diameter of 50mm, at 45 degrees;

reinforced scotch tape (for greater reliability);

good quality masking tape.

The described components for this method can be replaced by any suitable analogs..

Step-by-step instruction

Just five simple steps:

1) Place the angle grinder on the floor, table, etc. so that it lies with the disc upwards parallel to the plane of the base.

the angle grinder must be sufficiently stable.

2) We take a branch with pliers or some kind of clamp.

3) Turn on the angle grinder and literally saw in the branch pipe along the body, under the casing of the angle grinder, about 3 cm.

4) We take the reinforced tape, and tightly, in an interference fit, we attach the branch to the body of the angle grinder, with a slight approach (a couple of centimeters) into the saw blade.

The branch pipe must be fixed firmly so that it is kept absolutely still.

5) We take masking tape, and glue the open side of the casing with it, connecting it to the bend.

This design allows you to easily connect a construction vacuum cleaner and saw an angle grinder without dust..

For such work, you can only use a construction vacuum cleaner..

When sawing, the blade should be inserted into the material to be cut from the engine side, closer to the nozzle.

So all the dust will go through the outlet to the vacuum cleaner..

We cut objects with the engine forward.

The first way is wetting

The easiest way to cut dust-free concrete or brick is to wet them with water..

To do this, you can use a conventional spray bottle.

or a spray bottle (made from a plastic bottle with holes in the lid), or a children’s water gun / machine gun.

Spraying the object must be done directly during the saw so that the dust immediately gets wet, without having time to scatter.

Due to the fact that the angle grinder is busy with the hands of the saw, it is quite difficult and inconvenient for him to cut and spray at the same time, and besides, it is unsafe.

Therefore, a second person should be involved in spraying..

In tandem, all work can be done quickly and without difficulty..

This method does not require any significant effort, but it creates a lot of dirt, because dust turns into slurry, spills on the floor, and also flies in different directions.

The second way is more efficient and practical.

Safety engineering

Such a dust extraction system does not imply any major structural changes in the device angle grinder.

We just attached the pipe to the body of the instrument..

And the second part of the casing was closed with masking tape, this element can create a false impression of security.

Masking tape is only designed to protect against dust.

Therefore, it is necessary to comply with all safety measures when working with an angle grinder.

Straight cut

This is the simplest option, since it is enough to fix the tile on a horizontal surface using the bottom and side stops. You need to cut the tile so that the marking line is visible. This means that the angle grinder must be moved away from you. The bottom stops will provide a slight lift of the product above the table / floor, depending on where the work is being done. The straight-cut ceramic angle grinder implies the need to cut lines at 90 ° to the edge or to each other. The disc should pass at a distance of 3-5 mm from the line.

How to cut tile or ceramic tile angle grinder

The angle grinder allows you to cut off from the product not only areas of the correct geometric shape, but also curved stripes. It can be bends, or even circles. Cutting ceramic tiles with an angle grinder in the case when it is necessary to obtain a circle is more difficult. This is due to the fact that this material is more susceptible to deformation on the cutting line of the cut. Sequencing:

  • line of future cuts is applied to the tile;
  • the diamond disc is fixed to the tool using a special key that comes with the kit and is designed to install cutting discs with your own hands;
  • to avoid slipping in the process of cutting tiles, an angle grinder is installed on one side of the stop, it can be any relatively heavy object;
  • the tile is adjusted on the floor, you can also put the product on the table, but in any case, there must be an emphasis under the tile on both sides, which will allow the cutting edge to go through its entire thickness (otherwise the diamond disc will damage the table or floor finish);
  • tile cutting angle grinder is performed at the push of a button.

Wet cutting

If you plan to use water cooling, it is best to use a smooth cutting edge. This reduces the likelihood of chipping. Discs with serrated edges on the side of the cutting edge are also used. These protrusions also help cool the material. During wet cutting, water is applied to the cutting edge. The disc can be partially immersed in a container with liquid or a spray is directed at it from a spray bottle. All manipulations with water are performed after turning off the angle grinder.

How to cut tiles correctly with an angle grinder?

If the question of how to cut the tile with an angle grinder is being decided, a number of nuances should be taken into account so as not to damage the product. In the absence of other tools and equipment (tile cutter, glass cutter, electric machine for adjusting the finishing material), you can use an angle grinder (angle grinder). Its other name is an angle grinder. It is a compact multifunctional power tool that is often used to cut ceramic or porcelain tiles..

Preparatory stage

The answer to the question whether it is possible to cut tiles with an angle grinder will be positive, but it is necessary to choose the right attachment (cutting edge). With porcelain stoneware, which is characterized by increased strength, it is better to work with a diamond-coated disc. Ceramic material is easier to cut, but in this case, such a nozzle will work. Use a fine-dust diamond wheel.

In addition, before starting work, it is necessary to decide which cutting method will be used: dry or wet. In the first case, a lot of dust appears in the process. This is due to the fact that the material is characterized by high density and increased strength. As a result, cutting an angle grinder is accompanied by the release of a large number of tiny particles into the air..

Alternatively, you can choose wet cutting. In this case, a cooling system is used – water is supplied to the treated area of ​​the finishing material. When working with an angle grinder, it is difficult to organize the cooling of the disc in an automatic mode, for example, as it is implemented in electrical installations (electric tile cutters), where there is a special bath. If you plan to use an angle grinder, prepare a spray gun or a wide container with low sides to cool the diamond disc, which will allow you to lower the cutting edge into water, after turning off the angle grinder.

Work on a power tool must be carried out after a thorough inspection. The cutting disc can cause injury during the tile fitting process, so it is important to check the attachment and ensure that all other removable parts are securely installed. The angle grinder must be equipped with a special cover that reduces the rate of dust spreading into the air. To prevent debris from damaging the walls or plumbing fixtures, cover them if possible..

We make a tile cutter from an angle grinder with our own hands

You do not need to take the entire tool, only the cutting edge is used – a diamond disc. A workbench is used as a support, on the end part of which a metal sheet is fixed. Previously, a slot is made in it so that the disc passes. There should be a cutting edge mount under the insert. To increase the reliability of the structure, this part should be welded to the metal sheet. As a result, the semblance of a tile cutter is ready. Working on such a machine, the tile is fed away from you. In this case, a tile cut into two parts is obtained..

Diamond wheel

With this type of cutting edge, the thickness of the abrasive layer can vary. For working with an angle grinder in a domestic environment, it is recommended to purchase discs with a dusting of 2 mm thick. On machines, cutting edges are used with a sputtering of a smaller thickness. However, if you are cutting tiles with an angle grinder with such a diamond wheel at home, the chance of chipping increases. In addition, when working with discs of this type, there is an increased risk of knocks and jerks, which can damage the instrument..

Types of tiles

With the help of an angle grinder, the finishing material of varying degrees of strength is adjusted: tiles, porcelain stoneware. Considering that it is difficult to obtain a straight line without chips using this tool, the edge of the tile should not be close to the cut area. Unlike the tile cutter, which is limited in the length of the piece, the angle grinder can remove an area from either side of the tile. Details on


There are many ways to cut tiles. For this, special tools are used. For instance:

  • tile cutters;
  • nippers;
  • glass cutters;
  • drills with appropriate attachments;
  • Angle Grinder.

Each option has its own characteristics, advantages and disadvantages..

How to Cut Tile Without Dust — by Home Repair Tutor

For example, the tile cutter is a very popular tool used for this purpose. It can be performed in three variations:

  • electric;
  • manual;
  • tile cutter tongs.

The first option is more suitable for the conditions of mass work. This means that the volumes must be large. Such a device is capable of even the most durable materials from which tiles can be made..

In the process of cutting the material, water is supplied, which makes it possible to obtain smoother edges, not to heat the material and not to spread dust. The only drawback of such a device is its high price. Moreover, one-time work is not for him. Better to rent an electric tile cutter.

As a result, the hand model is a fairly popular model. But in this case, everything will have to be done by hand. An alternative is the tongs cutter. The tool is designed for thin metals. In this case, there is another drawback – subsequent processing of the ends is required – grinding. And this is not always good.

A glass cutter, a drill, as well as wire cutters, can also be used to cut tiles. In the first case, there is a limited thickness of products. As a result, the tiles may not cut through. The drill together with the nippers allows you to get a good cut..

Next, consider the application of the angle grinder in more detail..

Instructions on how to cut

angle grinder is the popular name for an angle grinder. Not everyone knows that people began to call this tool that way since the 70s. It was at this time that the first samples began to arrive in the Union. And they were called “Eltos-angle grinder”.

In general, an angle grinder is a multifunctional tool. It is capable of processing materials thanks to the diamond wheel. The unit allows you to perform not only a straight line, but also a figured cut.

Recommendation: It is not necessary to cut the tiles to the full thickness. If you make a line-cut, then the product will break very pliable..

Of course, when compared with the results of a tile cutter, an angle grinder has more fragmented edges. At the same time, preparatory manipulations are not needed to carry out the process..

The disadvantage is that you cannot do without dust and chips. The only thing is that they can be compensated for by the protective casing of the tool itself, personal protective equipment, as well as the use of a special disk. For example, a good cut quality, practically no chips can be provided by a disc designed for metal processing. This is largely possible due to the reinforced relatively smooth surface.

Tiles are easy to cut with wet cutting attachments. This will allow you to get the absence of chips, as well as a flat and smooth cutting surface. In this case, the nozzle must be new, and the cut itself must be made from the back of the tile..

How to cut tiles with an angle grinder: no chips or dust

Tiling is almost impossible without cut rows. As a rule, they are located along the edges. Very often, the need for cutting tiles appears at doorways, in the places where pipes are located, and so on – where neat laying is required. And for these purposes a special tool should be used. The correct choice of the device will allow you to get high-quality pieces, and therefore, to make the styling at a high level..


If an angle grinder is used for cutting, it is recommended to check the tool for damage and function before the procedure. You need to insert a disc to work on cement or metal. There is certainly a difference between them, but not significant..

It is necessary to inspect the tool itself, otherwise some flaws can ensure poor-quality work.

Do not forget about personal protective equipment. This means that you should also wear a hat on your head, protective gloves on your hands, and clothes on your body to protect your eyes – glasses. The latter is perhaps the most important. After all, dust, small fragments can get into the eyes with a very fast rotation of the disc. This can be a dangerous injury. Therefore, you should think about your own safety first..

Chips and dust are inevitable?

You can put it this way. Indeed, everyone can perform certain manipulations to reduce such negative phenomena..

In addition, you can watch video and photo materials about this. After all, a lot depends not only on the tool itself, attachments to it, but also on the cutting technique. This aspect also affects the presence of chips and dust..

Be that as it may, but it is important to devote enough time to this moment. And then the result will please you with the high quality of work..

Straight cut or straight cut

The standard, easiest way, which we advise to initially master for non-professionals.

  • We prepare the workpiece: for this we take a marker, a ruler, draw a line along which we will make a cut.
  • We place the workpiece on a straight surface, remove all unnecessary things that might interfere. To ensure accuracy, we fix the workpiece with a vice.
  • Let’s start sawing. It is not necessary to cut through the ceramic, but make an incision 1–5 mm deep (depending on the thickness of your workpiece). Remember that when entering the material, the number of revolutions decreases, later it can be increased. We lead the tool exactly, at the same speed, away from ourselves. Do not drive in a circle back and forth on the intended mowing line. We adhere to the planned trajectory as much as possible. When the cutting edge comes out, we slow down again to avoid chipping.
  • We break the workpiece into two parts. If necessary, clean at the cut with the appropriate tooling.

Cutting rectangular holes in tiles

For this type of sawing, you need a drill with a drill (recommended diameter – 5 mm) on a tile!

  • We outline the contours of the figure that we will cut out.
  • We fix the workpiece using a flat surface (this can be a large durable table or a special workbench).
  • Using a drilling tool, within the outlined contours, create holes in the corners of the intended rectangle.
  • Using an angle grinder, we cut the mowing line following the marked contour.
  • Removing the inner part of the shape.
  • If necessary, we modify the resulting area with an abrasive.

Cutting at an angle of 45 °

This type of cut is considered difficult. To improve the quality of the result, we advise you to work with a branded metal wheel reinforced with diamond plating..

  • Mark the place of the cut with a marker along the ruler.
  • We place and, if possible, fix the blank.
  • We place the disc with the outside to the bottom..
  • Using an angle grinder, cut the back side of the workpiece at an angle.
  • Following the marked mowing line, re-cut. This will allow you to achieve the most accurate and even result..
  • If necessary, adjust the place of the cut.

Cutting circles (round holes)

Before starting to cut the circle, prepare a drill, a carbide drill bit (3-4 mm is a suitable diameter), a compass. Let’s get started:

  • We put a point on the workpiece with a marker. This will be the center point of the circle..
  • Using a compass, draw the outline of a circle of the size you need.
  • Use a drill to create a hole at the center point..
  • Using an angle grinder, we make through cuts from the inner part of the contour of our circle.
  • We process irregularities with abrasive or sandpaper.

Curly cut or curly cut

The most difficult, skill-demanding variety. It is recommended that you entrust it to a professional if you do not consider yourself an experienced user. Unlike a straight cut, a curved cut cannot be made with a tile cutter: an angle grinder in this case is necessary.

So, you make an oval hole:

  • We make markings on the workpiece with a marker.
  • We fix the workpiece on a flat surface, fix it for the greatest reliability.
  • Getting started with an angle grinder: you need to make short notches, cutting off excess material.
  • At the end of the cut, irregularities will remain at the cut points. To finish the shape cutting, change the cutting disc with an abrasive wheel, work the kerf until the result is strong..

Stone circles

The most budgetary and unreliable option is stone discs. They wear out quickly, so a lot of them will be needed for a large amount of work. Due to the thickness of the tooling, the kerf will be wider than when using metal discs. It also contributes to the fact that when sawing, more dust particles remain.

Be sure to monitor the performance of the stone circle! If there is visible damage on the cutting edge (for example, chips), the tooling must be replaced. Otherwise, the work of the equipment will become unsafe: it can collapse, spoil the material or harm the user..

Wet cutting

The wet method implies that when exposed to the material, the cutting edge will come into contact with liquid during operation: the working edge is immersed in water, or it is supplied by a jet.

This method is more difficult to implement, but it has advantages:

  • Cooling the cutting edge.
  • Moisturizing the material to get rid of dust.

Starting renovations at home, craftsmen are faced with laying tiles in the bathroom. But it is necessary not only to carefully and evenly lay the tiles, but before that cut it. Not everyone has a set of tools, among which there is a tile cutter. Usually the choice of tools is limited, but if among them there is an angle grinder (angle grinder), then we will consider the option of using it for cutting tiles.

In the article, you will learn how to properly cut tiles using an angle grinder, which circle to cut porcelain stoneware more efficiently, what safety rules must be followed.

Sawing paving stones with an angle grinder

Having a private house, it becomes necessary to lay paving slabs or paving stones, which must be cut to size. For this, a universal device is also used, which is available in almost every home – an angle grinder.

Paving stone processing has its own characteristics, but basically it is carried out in the same way as cutting porcelain stoneware. The main differences are that the work is done outdoors. Material processing should be carried out on a separate site: the resulting dust settles on the laid paving stones and can spoil its appearance. If this happens, you should immediately sweep it off with a stiff brush..

To cut the paving stones, choose a diamond blade for concrete processing. The angle grinder should be held at right angles to the workpiece and the diamond wheel should be moved exactly along the mowing line. It is necessary to cut the tiles to a depth of a little more than half, and then simply break and trim.

Straight cut

It is not difficult to master it, at the same time the cutting line is clean and without chips. When performing the work, the tiles are securely fixed on a flat surface, marked with a pencil or felt-tip pen. The part to be cut should hang freely from the table. The cutting tool is at right angles to the workpiece. Carefully, without jerking, drive the angle grinder slowly along the marked mowing line. The tool should be moved towards you so that the marked line is visible..

Cutting tile and porcelain stoneware angle grinder

Every master who is engaged in wall cladding with ceramic tiles knows that it is impossible to lay them without cutting. This is true both for wall cladding and for laying porcelain stoneware on the floor. But not everyone knows that a regular angle grinder (angle grinder) can be used for trimming. Let’s consider how to perform this operation correctly and without chips..

Cutting ceramics

To cut tiles with an angle grinder, you need to master three cutting directions.

What discs are used for cutting tiles

For cutting ceramics, special discs are required, which can be stone or metal with diamond coating. Stone ones are rarely used, since they are quite thick and quickly grind off, and during work they generate a lot of dust. The cost of stone discs is several times less than metal ones, but experts prefer to work last.

Metal discs can be:

  • solid;
  • segmented.

It is preferable to process ceramics with solid discs. When working with such discs, there is a time limit: they cannot continuously cut for more than 1-1.5 minutes. Then let it cool down while the angle grinder is idling..

Segmented for cutting paving stones, porcelain stoneware, natural stone or concrete.

The segments are designed for better cooling of the tool during operation.

How to get rid of dust when cutting tiles

Tile cutting with an angle grinder is not very difficult, but it generates a lot of dust. There are techniques that can help reduce dust formation. Specialists use special tile cutters for this, but buying them for a one-time job is impractical due to the high cost. Therefore, when processing parts, the craftsmen act differently. First, a layer of glaze is cut through – it almost does not produce dust, the main dust appears when a layer of fired clay is processed. Then it remains to gently break the ceramic tile and process the edges with an abrasive material..

A common way to get rid of dust is to moisten the workpiece. To do this, water is constantly poured into the working area with a diamond wheel. After each pass of the tool, fill the seam with water or install a special device for supplying water to the working area. This device attaches directly to the protective cover of the angle grinder. As a result, the workpiece is processed without dust..

Notched neckline

It is often necessary to cut a round hole in a tile. You can do the job correctly with an angle grinder if you have certain skills. To do this, mark a hole on the workpiece and circle the fishing line with a felt-tip pen, mark the center of the circle. They begin to cut at a slight angle, slowly, along the inside of the mowing line, gradually passing along the entire circumference. Then the sectors are cut through, they are taken out in turn, cutting the ceramics if necessary. Finally, the edges are processed with a file, getting an even circle. Such processing is called a dry cutter..

Such holes, as a rule, are cut for sewers or ventilation..

When performing shaped processing of a workpiece, it is easiest to make rectangular cuts. In order for the cuts to be smooth, without chips, it is necessary to regularly change the cutting wheel. If you use segmented discs, then chips will appear on the cut line..

Angle 45 0

Docking is often necessary, which means cutting the material at an angle of forty-five degrees. This angle can only be obtained with a large workout. But you can use this technique: first, cut the workpiece in a straight line, and then gently process the edge at the desired angle with a disc, sandpaper or sharpening stone.

Is it possible to cut the porcelain stoneware angle grinder

Of course, an angle grinder can cut anything you want, with the possible exception of glass or particularly complex ceramic products. But it is not so easy to cut the porcelain stoneware with an angle grinder so as to achieve a perfectly straight cut line..

Of all the reasons that prevent high-quality cutting of porcelain stoneware, the most important ones are distinguished:

  • an angle grinder is a hand tool, and often the material has to be cut, as they say, by weight, as a result, the disk deviates from the cutting plane, this leads to the formation of chips, and sometimes cracking of porcelain stoneware;
  • The cut-off wheel is not selected correctly. In the first experiments, beginners try to cut porcelain stoneware with cut-off vulcanite discs over stone and concrete. With this material, you can cut off a small part of the tile, but most often the result is negative;
  • Incorrect cutting mode or no cooling of the cut line. The desire to cut off faster leads to excessive pressure on the tool, as a result, the circle and the tile itself break, not to mention the fact that the entire line of the cut remains covered with chips and microcracks.

In theory, cutting porcelain stoneware is no more difficult than any other facing material, you just need to choose the right mode, cutting speed, pressing force and choose the right cutting tool.

If you cut an angle grinder by weight, then chips must appear

Cutting an angle grinder on weight is possible only for those who have strong enough hands. If you have to saw at least 20 cm in length, then even experienced and strong craftsmen get tired hands very quickly, the circle begins to deviate from the vertical plane, as a result, the seam begins to wag, and chips appear.

Sole-based cutting

How To Correctly Cut A Highly Raised Angle Grinder

Most beginners and DIYers prefer to cut porcelain stoneware with a tool with a very large angle of inclination relative to the plane of the tile. The angle can be 45-60 °.

The tool can only be lifted high if there is a supporting surface on the cover.

In this case, the angle grinder must be held with both hands and at the same time perform small oscillatory movements with the cutting disc. It is as if the porcelain stoneware had to be cut with a hand saw. This is not very convenient, but the method really improves the quality of the cut and prevents the formation of chips..

On the one hand, with such a movement, the angle grinder is easier to control the line of the cut, on the other hand, the tool is in an unstable position relative to the markings, which negatively affects the quality of the straightness of the seam..

How to get rid of dust when cutting porcelain stoneware angle grinder

If the tiles are cut on a table, then before starting work, a small piece of loose fabric must be pulled under the cutting line or a polypropylene bag must be hung. In this case, most of the dust flies down from the disk, so the amount of work on cleaning the room is reduced several times.

If you cut porcelain stoneware on a substrate directly on the floor, then the best solution would be to use a regular vacuum cleaner. The tip of the hose is attached along the mowing line of the movement of the angle grinder at a distance of 10-15 cm. It turns out not very convenient, since the nozzle has to be rearranged, but the dust is removed quite effectively. Immediately after completion of work, you need to blow out the angle grinder and collect part of the dust remaining on the surface of the porcelain stoneware..

Useful Tips

There are various models of angle grinder attachments on sale, some of them provide connection of the vacuum cleaner nozzle to the protective cover of the tool. At first glance, the thing is quite convenient, but it is better not to use such devices, since the hose greatly interferes with work and often only worsens the quality of the seam.

In addition, it is necessary to cut porcelain stoneware, be sure to hold the body of the angle grinder with both hands, while the left hand should rest on the stand or guide rail, and the right hand should directly move the tool. This method provides not only partial unloading of the hands, but also allows you to more accurately align the position of the cutting disc in the vertical plane..

Regardless of which disc and how to cut the porcelain stoneware, after the completion of the work, the edge must be rubbed with hand or tape emery. In this case, you just need to slightly align the lower edge of the porcelain stoneware and in no case touch the upper front edge with an abrasive, otherwise chips will appear, and the quality of the seam will noticeably deteriorate.

Cutting porcelain stoneware with an angle grinder: how to saw off without chips

Everyone who has had a chance to cut faience, ceramics, porcelain stoneware with a cutting disc knows perfectly well that the problem is not how to cut. Such an operation is not particularly difficult. The problem is learning how to cut a porcelain stoneware angle grinder without chipping. At the same time, control the process at any stage, otherwise the expensive material will go to scrap.

The best way to cut porcelain stoneware is using a guide bar as a support for the angle grinder case

Direct cutting of porcelain stoneware

It is considered correct to cut a porcelain stoneware slab on a table or workbench. The material is laid on the tabletop, fixed with clamps with rubber tips. the cut line should be outside the table surface. In this case, it is possible to cut porcelain stoneware with a very small angle of inclination, only 15-20 degrees. The master simply pulls the angle grinder towards himself, only lightly resting his hand on the stand.

Cutting Option Pull Angle Grinder

Why this method is good:

  • The minimum load on the hands, if you need to cut a sufficiently long seam, this will not be difficult to do;
  • the cutting line turns out to be even, it seems that the cutting was carried out not by an angle grinder, but by a tile cutter.

The only disadvantage of this method is that most of the dust escaping from under the disc falls on the floor, and the largest parts fall into the face and hands of the worker. Therefore, it is necessary to cut porcelain stoneware with protective goggles and using devices for collecting dust..

How to cut a porcelain stoneware angle grinder without chips

There are two ways to cut porcelain stoneware tiles. The first is to mark a 1-2 mm deep line on the mowing line and then split the porcelain stoneware into two halves as it is done on a tile cutter. The method is quite risky, it requires a good eye and accurate dosing of effort. The advantages include an order of magnitude higher cutting performance. The disadvantages include the unpredictability of the result and a large percentage of rejects..

The second method is the classic cutting of porcelain stoneware to the full thickness of the tile. It turns out a lot of dust, the process takes a long time, but as a result, we get a very high-quality and fairly even cut.

In any case, when using an angle grinder, the seam is uneven. Visually, the line looks perfectly straight, but as soon as the cut plates are turned over and applied to the factory edge or metal ruler, all the irregularities will immediately become visible. An example of cutting porcelain stoneware with an angle grinder without chips is shown on
