How to cut ceramic tile angle grinder
How to avoid chips
To cut the tiles evenly and without deformations, you should adhere to the recommendations:
- Masking tape is glued on the site of the planned cut.
- It is recommended to work on the front side of the product, which is due to an increase in the number of chips at the exit of the cutting edge.
- It is possible to cut the tile with an angle grinder without chipping if you do not exert excessive pressure on the surface during the process.
- To protect the cut from chipping, it is recommended to work with a thinner diamond blade.
- The incision is made single.
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
Cutting tiles at 45 degrees
Using a handy tool, you can chamfer at an angle of 45 °. If an angle grinder is used, the tile is fixed in an upright position. The tool is positioned so that the angle of inclination of the cutting edge is 45 °. The fit is carried out by weight. If you use a homemade tile cutter from an angle grinder, in this case the diamond disc is fixed in one position, so you need to chamfer the tile edge in another way. holding it at an angle next to the disc. Then the surface of the cut is sanded with sandpaper.

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.
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.
Methods for cutting porcelain stoneware
This is a material of increased strength, which means that it is less prone to chipping. For this reason, often with the help of an angle grinder, not only straight mowing lines are made, but also bends, and also cut out circles. Working with porcelain stoneware follows the previously discussed scheme for tiles. However, unlike ceramic material, in this case it is allowed to make large holes and cut out small circles, while the likelihood of damage to the tiles is low.
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, working with these types of discs increases the risk of knocks and jerks, which can damage the instrument.
If you plan to use water cooling, it is best to use a smooth cutting edge. This reduces the likelihood of chipping. Also used are discs with notches on the side of the cutting edge. These protrusions also help cool the material. During the wet cutting process, 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.
Ceramic Cutting Discs Angle Grinder
To cut ceramic tiles, an angle grinder uses stone or diamond-coated steel discs (dry cutters). Dry cutters, in turn, are divided into solid and segmented. The more intense the diamond spraying on the dry cutter, the more efficient and durable the disc will be.
Discs come in stone or steel
Stone discs are several times cheaper than dry cutters, but they wear out during operation and must be replaced with new ones. In addition, they are thicker than dry cutters, so the thickness of the mowing line for cutting with a stone nozzle is wider and, accordingly, more dust is generated during operation.
In the process of cutting with a stone nozzle, it is necessary to control the condition of its cutting edge. if a chip or burr forms on the edge, the disc must be replaced immediately, since such damage is fraught with destruction of the nozzle and causing injury.
Safety instructions for working angle grinder
To avoid injury while working with the angle grinder, the following rules must be observed:
- when working, use personal protective equipment. gloves, overalls, safety shoes, glasses, respirator;
- you can work as a grinder only with a steel protective cover installed on the tool;
- the length of the grinder’s electric cable must be at least 2 m, which reduces the risk of damage by a rotating disc during operation;
- cut in the direction “away from you”, holding the tool with both hands;
- the direction of rotation of the disc must coincide with the direction of translation of the angle grinder;
- cut the material by immersing the grinder disc into the cutting line no more than one third of the radius;
- each material must be processed with the appropriate disc, that is, the ceramic tile must not be cut with a metal cutting attachment, and the cut-off stone disc is not intended for grinding ceramics (grinding with a steel “dry cutter” is possible);
- during operation of the angle grinder, both extremely low and maximum high speed values should be avoided;
- cutting with a grinder material immersed in water in order to reduce the amount of dust generated is prohibited due to the danger of electric shock;
Dust is explosive, so cut or grind material with an angle grinder in a well-ventilated area.
How To Cut Ceramic Angle Grinder
One of the tools used to cut ceramic tiles is a grinder. an angle grinder (angle grinder), commonly referred to as an angle grinder.
- Safety instructions for working angle grinder
- Ceramic Cutting Discs Angle Grinder
- Stone discs
- Dry cutters
- Segmented dry cutters
- Solid dry cutters
- Direct Cutting Ceramic Angle Grinder
- Angle Grinder Cutting Large Holes
- Cutting rectangular holes in tiles with a grinder
- Shaped tile cutting angle grinder
The price range of various grinder models makes it available not only to professionals, but also to home craftsmen, so when using an angle grinder, you need to know not only the capabilities of this power tool, but also the rules for handling it in order to avoid injury.
angle grinder is best used with adjustable speed
At home, a small grinder is used, designed to work with discs with a diameter of 100-125 mm and performing many operations. The tool can be equipped with a speed controller.
A dry cutter can cut ceramic tiles without water cooling, but the duration of one continuous cut should not exceed 1-1.5 minutes, after which the disk is allowed to cool while rotating idle. When buying a dry cutter, they prefer a tool with a solid diamond coating.
Dry cutters for cutting stone
If, during cutting, a solid glowing spark-strip appears on the cutting edge of the dry cutter. the phenomenon of “licking” the metal, then the temperature at the cutting point of the tile in such a situation rises sharply, which is fraught with damage to the material. In this case, with a rotating dry cutter, you can make several cuts on any abrasive surface (concrete, plaster), and the disc comes back into working condition.
Dry cutters are divided into 2 types:
Direct Cutting Ceramic Angle Grinder
On the front side of the ceramic tile, a cutting line is applied with an alcohol marker. the angle grinder is turned on and given a couple of seconds to set the set speed.
The disc on the grinder must be fixed correctly. using a special key and in accordance with the direction of rotation indicated on it.
The optimum rotational speed of a disc with a diameter of 100-125 mm when cutting ceramic tiles is 6-8 thousand rpm. The tile is placed on a flat wooden surface, secured with a clamp through a rubber sheet gasket, or you can simply press it against the board with the sole of your foot (shod in safety shoes!).
Cutting ceramic tiles can be straight and curly
Exactly along the intended mowing line, an incision is made with a depth of 1-5 mm, depending on the material and thickness of the tile. From the edge of the material, they begin to cut slowly, then the angle grinder is moved faster. this way the cut is smoother. After making a cut, the tile can be broken by placing a pair of nails under it opposite the beginning and end of the cut.
Shaped tile cutting angle grinder
If it is required to cut an oval shape from a ceramic tile, then short cuts are made with an angle grinder tangentially to the outer contour of the figure in order to cut off small fragments of ceramic to be removed. At the end of cutting, the surface of the cuts is refined with an abrasive tool until the lines are smooth and there are no chips.
When it is necessary to cut a figured hole in the tile, the angle grinder cuts the material exactly along the contour, gradually moving away from it inward and increasing the depth of the cut. After cutting through the tile, the edges of the hole are finished with coarse sandpaper.
How to cut ceramic tile angle grinder
When cutting ceramic tiles with any tool, there are disadvantages: chips, irregularities.
The tile cutter allows you to cut tiles of almost any size and thickness, the work is done quickly and almost silently. But with it, you can only make straight cuts. The tool is expensive, it is impractical to purchase it for a small amount of work. For drilling circular holes, crown cutters are used, which are also expensive. Therefore, most craftsmen use an angle grinder for these purposes, which almost every owner has. With its help, you can make cuts of any shape, including circular.
When cutting an angle grinder, there are disadvantages: a lot of dust and noise, chips and damage to the enamel form at the edges, the process takes longer than cutting with a tile cutter or drilling holes with core cutters.
Tips and tricks on how to cut tiles with an angle grinder
For cutting ceramics, some craftsmen use cutting discs for metal, but for high-quality and fast work, you should purchase a disc for cutting stone or ceramics, preferably with diamond dusting. The smaller the disc diameter and the weight of the angle grinder, the easier it is to work and the more accurate the cut will be. It is desirable that the angle grinder has a smooth start. Optimum disc diameter. 110-125 mm.
All types of work need to start from the front, eliminate defects and adjust from the back. In which direction to move the angle grinder during a straight cut. towards yourself or away from you. it does not matter.
If in hard-to-reach places it is problematic to accurately determine the mowing line of the cut, it is better to cut out a piece of cardboard, make sure that it fits exactly, and apply markings on it.
To get a circular hole for switches, sockets, plumbing equipment, you need to proceed in the following order. On the front side of the tile, a circle is drawn with a diameter of 1-2 mm larger than the diameter of the required hole. If a drill is available for drilling in glass or ceramics, a hole is made in the center to accurately determine the center of the circle and draw it on the back. With a disc, cuts are made on both sides of the tile perpendicular to the surface to the maximum depth so that they do not go beyond the circumference. Inside the circle, through its center, two or more through cuts are made to the circle. The resulting sectors of the circle must be broken out. If this fails, you need to use a disc to reduce the thickness of the tile inside the circle, moving it from the circle to the center.
The work is dusty, it must be done in a respirator or in the fresh air, wearing protective goggles, in good lighting.
Whatever tool the tiles are cut with, defects are inevitable. Therefore, clipped elements should be installed where they are less visible. It is not necessary to level the cutting line of the cut and remove chips using an angle grinder, they should be processed with sandpaper, a flat or round file, an electric drill with a special nozzle. Decorative overlays of various diameters are on sale to hide defects in circular cuts for plumbing pipes.
The simplest processing option that even beginners can handle is cutting tiles with an angle grinder along a straight mowing line. To begin with, the tool is fixed on a flat surface. It must be positioned so that the cutting edge hangs from the platform. The direction of the cut must remain within the tiler’s line of sight, with the tiles laid face up.
Hold the sander with the cutting direction away from you while moving along the intended mowing line. Ideally, the cut should be done in one pass, only then it will turn out smooth.
Is it possible to cut tiles with an angle grinder?
Another tool for processing tiles is a tile cutter. But not every owner has this device in the arsenal, but with an angle grinder everything is somewhat simpler. In addition, the tile cutter cannot handle complex curly cuts with exact observance of the given geometry and parameters.
Another advantage of the angle grinder is the ability to use a variety of discs. They can be selected in accordance with the type of tile, its thickness and coating characteristics.
Cutting at a 45 degree angle
An angle grinder is necessary to cut tiles when installing plastic or metal corners. This will help form a beautiful bevel edge when laying diagonally.
An even and fast cut can only be done with a diamond-coated nozzle. The tile is placed under the edge with the glazed side down. Positioning the angle grinder at an angle of 45 °, grind the back side. Once the corner is formed, the actions are repeated, moving in a circle along the edge of the cut.
Some craftsmen start with rectangular tile cutting. Then the nozzle is guided so as to remove the excess ceramic at a predetermined angle. Finish work by sanding the edge.
How to turn an angle grinder into a tile cutter?
The design of the angle grinder does not allow cutting with maximum emphasis. the device will have to be constantly suspended or an assistant is involved. The most rational solution is to slightly modify the angle grinder, turning it into a convenient and safer electric cutter.
To begin with, choose the most convenient and spacious place for the location of the machine. The basis for an angle grinder can be a sheet of metal with a groove to deepen the cutting edge. The gutter will be a kind of mark on which you can navigate when performing work.
Then proceed to fixing the grinder. In this matter, special clamps will help, which can firmly fix the tool body. Improve your improvised tile cutter by adding a water tank to cool the blade and a wet cutting attachment.
Steel is a complex alloy of iron with carbon and impurities in the form of silicon, sulfur, manganese and phosphorus. The carbon component, which does not exceed 2.14%, gives the steel high strength and hardness. This allows the metal to be used as a base material for the production of cutting discs for an angle grinder.
In some cases, the steel discs are diamond-coated, giving the cutting edge unprecedented strength.
Another option for coating steel nozzles is alumina. It is an abrasive made of crystalline alumina or synthetic corundum, which increases the sawing properties of the disc. Such nozzles are marked in blue and are used for cutting various metal elements. profiles, sheets, angles, fittings and pipes.
Combined disc models
Tile cutting discs angle grinder got a similar name due to its ability to work both dry and wet. This is an intermediate option between segmented wheels and dry cutters:
- cuts better than segment, but worse than solid;
- works continuously more solid, but less dry-cutting.
Most often, combined circles are used in the field of cutting brick and concrete, but their use is allowed when carrying out facing work. The disadvantage of combi models is the tendency to quickly clog with dust.
angle grinder cuts only large-diameter holes. small ones are made with a drill or perforator.
- Through the center of the circle hole, two straight mowing lines are marked, located perpendicular to each other.
- While guiding the grinder at an angle, make a small indentation along the circumference, trying to adhere to its inner diameter.
- Move gradually in a circle, evenly filing the thickness of the tile.
- Once the depth is sufficient, cut straight perpendicular to the mowing line through the center of the circle.
- Carefully remove the first segment to avoid chipping, then remove or knock out the remaining three.
It is more difficult than the first option, it requires a certain skill. The tile is processed with short cuts along the tangent of the mowing line to the outer contour of the drawn figure (oval, circle). This will allow you to cut off small extra fragments, and then achieve the desired configuration.
They also plan small allowances for trimming, and at the end they refine the contour by grinding, achieving smooth lines and removing chips.
How and how to cut ceramic tiles. an overview of methods and devices
When planning the laying of tiles, you need to decide on what to cut ceramic tiles. Facing material is available in several versions, and for each type of tile there is a priority method for cutting it. You will learn more about how to cut various tiles, and what devices exist for this.
- 1 Varieties of facing material and features of its various types
- 2 Glass cutter. an inexpensive option for small volumes
- 3 Manual tile cutter. the best choice for domestic use
- 4 Water saw. fast, precise and dust-free
- 5 angle grinder. universal tool for cutting all types of tiles
The basis of most types of tiles produced now is fired clay. ceramics. On the front side, the tile is covered with a thin, but more durable waterproof coating, which at the same time carries an aesthetic load. The cladding material is divided into two types:
- wall-mounted (for finishing vertical surfaces);
- for floor cladding.
Floor tiles can be indoor and outdoor (for installation on thresholds, verandas, terraces). Floor cladding material intended for indoor use is usually made with a smooth front surface, outdoor tiles often have special anti-slip protrusions or a rough surface, which is taken into account when choosing a cutter.
Wall tiles are easier to cut than floor tiles because they are thinner
With wall cladding material, not everything is simple either. In addition to the most common tile, which has a smooth decorative surface, there is a tile with a relief finishing layer (including a frieze. dividing elements between the panel part of the wall and its “top”). Not all methods for cutting smooth tiles are suitable for corrugated surfaces.
When choosing ways of how to cut a tile, its thickness, strength, the area of the intended cladding and the complexity of the geometry of the pattern are taken into account. Wall tiles are thinner than floor tiles and less durable, so a regular glass cutter or manual mechanical tile cutter is suitable for cutting. Floor cladding material requires a more serious tool, especially if its surface is rough or has anti-slip protrusions. If a lot of complex patterns are expected (holes for sockets, bypassing pipe communications), you should take care of the availability of devices for curly patterns of tiles.
When deciding with which device to cut tiles at home, you should take into account the volume of the proposed finish. For small areas and simple patterns, a simple tool will do. If there is a lot of work, it makes sense to use more advanced devices so that the tile does not have to be cut off longer than it is laid.
Now ceramic tiles are cut using several devices that differ in structural complexity and functionality.
using a angle grinder to cut ceramic tiles
If you have to cut ceramic tiles at home, while the cladding area is small (for example, a kitchen panel), a regular glass cutter is suitable for work. These simple tools can be equipped with a cutting roller or diamond tip. Choose a glass cutter that has to work or whichever is more convenient. you can cut a tile with any type of tool.
If you need to cut a small amount of tiles, any glass cutter will do.
How to cut tiles with a glass cutter correctly? The essence of the process is identical to working with glass: you need to scratch a groove on the front surface, which will become a fracture line. To do this, first we remove the dimensions of the fragment necessary for laying, make the appropriate marks on the decorative side of the whole tile and draw a straight line corresponding to the intended cut with a marker. The tile is laid on a flat surface at a height convenient for work (table, workbench). The working part of the glass cutter with medium uniform pressure makes a movement from the far end of the tile towards itself.
In this case, a clear, shallow groove should be formed without areas of interruption. To make the cut as straight as possible, you can use a guide bar. But it is better to make the cut under visual control, aligning the cutter with the drawn line. It is not advisable to carry out twice with a glass cutter along one mowing line. it is very difficult to get into the same furrow a second time. As a result, the cut will not be of very high quality. You need to try to make a furrow in one motion.
Then we do the following. If the cut-off part is more than 3-4 cm, place the tiles on a table (face up) or other hard surface so that the cut line coincides with the edge of the stand. We put the wider part on the table, the narrow section hangs down. Firmly holding the part of the tile that lies on the table, you need to sharply press on the hanging fragment, as a result of which it breaks off exactly along the drawn furrow. When the width of the cut fragment is small, another tactic is used. the excess part of the tile is gradually broken off with special nippers. If they are not at hand, you can use ordinary pliers for these purposes.
Cutting tiles with a glass cutter requires dexterity and hand firmness. These qualities are acquired quickly, so do not be upset if the desired result does not work out the first time. To quickly acquire the skill, you can sacrifice one tile, and make many different strips and rectangles from it, making cuts with a glass cutter, and then proceed to the pattern of the tiles necessary for laying.
Glass cutter is only suitable for working with smooth tiles
The glass cutter is suitable for working with smooth wall tiles. The corrugated surface of the tile cannot be cut off with this tool. It is very inconvenient and takes a long time to make circular patterns using a glass cutter. To do this, you will have to soak the tile for at least an hour (so that the ceramic base is soaked), make a circular cut, and then look for a suitable stand that best matches the geometry of the intended hole. The tile is placed on a stand and gradually, with gentle pressure, the cut area is forced to separate from the main fragment of the tile. It is problematic to cope with thick and durable floor tiles with a glass cutter, therefore, if it is necessary to cut this type of tile, it is advisable to use more advanced devices.
A manual tile cutter is essentially an improved glass cutter, and its cutting element is the same roller, only more massive and durable, designed for more force. Increases the pressing force in the device under consideration, a lever that forms a single mechanism with the cutting wheel and is fixed on a carriage moving along two parallel runners. The guides are fixed on a bed, equipped with a stand from below, on which the tiles to be cut are laid. A metal protrusion is built into the support, corresponding to the stroke of the cutting element, which serves as a stop when breaking tiles. A special device (press) is movably attached to the movable carriage next to the cutting roller, with the help of which pressure is transferred from the lever to both halves of the tile being cut.
There are many models of manual tile cutters, differing in the following characteristics that affect the performance of the fixture:
- maximum tile size that can be cut;
- the mechanism for sliding the carriage along the guide rails (dry running, lubrication, bearings);
- backlash of the cutting element;
- material for manufacturing the main parts of the device;
- equipping with an additional tool for cutting circular holes.
With a better performance of tile cutters, their cost increases accordingly, therefore, when choosing a cutting device, you should understand for what purposes it is needed. If a one-time job of laying tiles is expected in relatively small volumes, it is impractical to buy a model at a cost above average. an inexpensive product will do. When the plans include large areas for laying tiles, it makes sense to purchase a model at a higher price. High-quality manual tile cutters are widely used in their activities even by professional tilers.
To properly cut the tile with a tile cutter, follow the steps below:
- 1. Mark the notch line on the front side, after making the necessary measurements.
- 2. We lay the tiles on the bed so that the scribbled line coincides with the longitudinal ledge on the base.
- 3. Using the lever, carefully place the cutting wheel on the far edge of the tile (the cutter should coincide with the beginning of the approximate mowing line).
- 4. Slightly pressing the lever, pull it in a continuous movement towards you until the wheel comes off the tile.
- 5. Raise the lever and install a kind of double-sided press on the tile approximately in the middle of the cut mowing line.
- 6. Press the lever (not very hard and smoothly enough), as a result of which the tile breaks into two parts.
To acquire initial skills in using the device, it is advisable to make several trial attempts.
If the tile is large (the cut is longer than 30 cm), it is advisable to press on the cut tile several times, moving the press to different places. So the fault will be smooth and you will not have to modify it.
It is convenient to work with a manual tile cutter, but there are some limitations. This device, like the glass cutter, does not work on embossed tile surfaces and some types of floor tiles, especially outdoor ones, are also too tough for the tool. In addition, the tile cutter will not be able to cut strips less than 15-20 mm.
A water saw is sometimes called an electric tile cutter, which resembles a circular in design and belongs to professional tools with the corresponding capabilities and cost. The device is equipped with a work table, in the longitudinal hole of which a diamond-coated cutting disc rotates. The peculiarity of the electric tile cutter is that the tiles are cut in the presence of water, which wets the disc abundantly. It enters the place of the cut through a special nozzle (in more expensive models) or the disc is wetted, being partially submerged in a pan with water.
Water saw. professional tool suitable for cutting any tile
How To Cut Porcelain Tiles by Hand with Grinder without Chipping. Testing Diamond Blades 4 Tiling
A wet cut at high blade speeds allows you to form an ideal cutting edge that does not differ from the factory one (a chamfer is formed at an angle of 45%). Due to constant wetting, no dust is generated during cutting, as well as chips on the cut-off tile edge. It is possible not only straight, but also figured cutting, the formation of holes of various configurations and sizes. The quality and type of tiles affects only the cutting speed, and even then only slightly. The water saw will cut a strip of any width from any tile. wall, floor, and even porcelain stoneware. An electric tile cutter is the best option for cutting indoor and outdoor floor tiles as well as textured tiles. At the same time, you do not need to use plastic corners when laying the facing material, covering the cut edge. it is enough to fill the corner joint with tile grout.
If there is no such equipment at hand (which is not surprising), but at the same time you need to cut different types of tiles, cutting out holes of various shapes and sizes, you can use a universal power tool, one of the models of which will certainly be found in the arsenal of any home craftsman.
Angle grinders (angle grinder) or angle grinder are versatile power tools with a wide range of applications in everyday life and in small industries. An angle grinder is also used for cutting tiles of various types, equipping with special “tile” discs or ordinary circles on concrete (there is no big difference between the result of the work of these attachments when cutting ceramic tiles).
The angle grinder can also cut any tile, however the cut edge will not be ideal
If a tile cutter or other specialized tool is not available, the tile can be cut with an angle grinder. an angle grinder can cut any tile. wall, floor, porcelain stoneware. In this case, the surface relief, strength and thickness of the tile do not play a role. The cut edge is not as smooth and problem-free as when an electric tile cutter is working, but taking into account the use of tile grout or plastic corners when laying tiles, small flaws are acceptable.
To cut high quality tiles without a tile cutter using an angle grinder, it is advisable to use a small angle grinder designed for a disc diameter of up to 125 mm. They are more convenient to work, especially when shaped cutting and forming holes in tiles. But it should be borne in mind that an angle grinder with a small diameter of discs usually has high speed (3600 rpm and higher), at which the tile at the cutting site overheats, it can crack and numerous chips, therefore it is advisable to use an angle grinder with an adjustable number of revolutions.
An angle grinder is convenient to cut tiles, but it reveals several disadvantages of this process:
- a lot of dust is formed. it is impossible to work in a closed small room;
- when cutting, many small pieces of ceramics fly off, so the process requires compliance with safety rules and the use of personal protective equipment (glasses. required, respirator. desirable);
- there is a possibility of electric shock, and in general, an angle grinder is a dangerous tool.
To cut a fragment of a tile in a straight line with an angle grinder, the necessary measurements are made and the desired area is marked with a reference line, after which the tile is laid on a flat surface, but not very hard (a piece of board, plywood, OSB boards). It is necessary to cut through the tiles to the full thickness only in cases of cutting off narrow strips, in other situations only the decorative layer is notched, after which the tile breaks, as described above. Cutting holes with an angle grinder (circular or rectangular) is done from the back side. this way less chips and other damage to the front side of the tile are formed.
When using an angle grinder to cut tiles, use only new, undamaged discs. Old worn-out working wheels will make a cutting edge with a large number of defects, while there is a danger of their destruction during work, which threatens with serious injuries.
The described tools for cutting tiles are rarely used in isolation. it is much more expedient to combine the use of different methods. For example, when laying wall tiles to cut straight fragments, it is good to use an inexpensive manual tile cutter or even a glass cutter (quickly, you can not leave the room), for curly patterns and cutting thin strips, you can sometimes choose an angle grinder when working in an open space.
