Cutting tiles with a grinder with which disc

Stone discs

Discs made of stone have only one distinct advantage. affordable cost. But the disadvantages of this type of attachment are much more:

  • short service life;
  • rapid wear;
  • large cutting thickness.

Since it is impossible to make fine cutting of tiles with stone discs, a lot of dust is generated during the work. The accessory creates a number of restrictions in processing. it is used mainly for making simple straight cuts. But for thinner and curly sawing, such discs are not suitable.

Solid dry cutters

Unlike segmented circles, these circles have a flat surface, which makes them versatile. A grinder with a solid nozzle can not only perform cuts, but also process the edge of the tile with the side of the disc. The absence of slots makes the wheel incapable of continuous work. it can rotate for a maximum of 15 seconds, after which a break of half a minute is required. If there is a need to cut tiles for longer, it will be advisable to use water cooling.

There are three options for supplying water to the work area:

  • attract an assistant who will pour liquid from a plastic bottle;
  • attach a special nozzle to the body;
  • using clamps, screw the armored hose connected to the water supply to the casing.

But water must be used very carefully. if liquid gets under the body of the device, you can get an electric shock.

cutting, tiles, grinder, which, disc

Tile cutting disc

Experienced tilers claim that the most convenient and effective device for trimming tiles is an angle grinder, popularly called a grinder. The main functional load in the unit falls on a replaceable cutting element, which is a disc of a given diameter and modification. How to choose the right disc for cutting tiles, what determines the price of a part, and how to work correctly with a cutting tool.

Combined

Combination wheels combine dry and wet cutting capabilities. This nozzle is a cross between solid and segmented discs. In terms of cut quality, it is inferior to solid modifications, but outperforms segmented ones. As for the time of continuous operation, it requires breaks more often than segment, but less often than continuous.

Do not use water cooling on the combination disc. It does not withstand temperature extremes, it expands unevenly under the influence of liquid, which is fraught with rupture.

Fine work disc

For those tile elements where you need to achieve high accuracy and a certain cut configuration, it is recommended to choose a disc more carefully. It is better to use a circle of small thickness. about 1.5 mm. It will facilitate the manipulation of the grinder, will not make a wide cut and will not damage fragile tiles.

The result of the work largely depends on the cutting technique. To create oval shapes, the grinder makes short cuts tangentially to the outer contour, trying to cut off unnecessary areas.

Segmented dry cutters

In segmented dry cutters, functional slots are provided along the perimeter, directed from the cutting edge to the center hole. Radial cutouts allow free expansion of heated metal and more efficient heat dissipation by air cooling. This allows you to increase the time of continuous rotation. a grinder with a segmented disc can work for 1-1.5 minutes with a 20-second pause.

Steel rims

Blades made of steel form a large product group, which includes wheels for dry and wet cutting, as well as combined models. Steel discs are very tough and durable, and diamond-coated makes them suitable for the hardest materials.

Diamond grit is applied by the manufacturer in three methods:

  • silver solder. the cheapest products suitable for household use. Potential service life is low due to the loss of strength of the solder when heated;
  • laser soldering. heavy-duty wheels of a high price segment, used on an industrial scale. They perfectly cope with the processing of workpieces of any strength;
  • form-fitting. diamond chips are embedded in the surface during the heating of the disc edge with electricity. They belong to the middle price segment, they serve for a relatively long time, which makes it possible to recommend them for processing large volumes of tiles.

Cutting rectangular holes in tiles

In this case, you need to prepare a drill to make holes along the edge.

Work progress:

  • Mark the hole with a marker.
  • Fix the tiles on a flat surface.
  • Drill holes in the corners of the marked rectangle.
  • Using a grinder, walk along the contours of the outlined rectangle.
  • Remove the inside.
  • Finish the edges with an abrasive.

Segmented dry cutters

This type of rig is distinguished by the fact that its surface is divided into identical segments. And the cutting edge is diamond-coated.

Thanks to the slots, the disc has the ability to partially cool during use. This increases the duration of continuous operation up to 1.5 minutes. After that, it is necessary to allow the tool to cool down, taking it to the side and keeping it idling for 30 seconds.

Segmented blades are for dry cutting only

Stone discs

The most budgetary option, but in terms of reliability it is inferior to all other types. When using it, the thickness of the cut will be much thicker, and a lot of dust will be generated during operation.

Cutting tiles with a diamond wheel and a MAKITA angle grinder

In the process of use, you need to monitor the condition of the stone circle. And as soon as chips appear on it, replace.

Is it possible to cut tiles with a grinder

The grinder can cut any kind of ceramic tile. The only problem is that this type of work is quite traumatic, and also requires a certain skill. over, this procedure will take longer.

Before making basic cuts, it is recommended to practice on the rough pieces.

How to cut tiles with a grinder at home

When laying ceramic tiles, it will not be possible to do without cuts. over, they can be straight and curved, in the form of a circle. For each type of work, a certain type of tool is required. At home, you can use a grinder or an angle grinder. But in order to make high-quality cuts, you need to know which disc for a ceramic tile grinder should be chosen. And also it is advisable to familiarize yourself with the features of the use of this tool.

The process of cutting tiles with a grinder requires certain skills.

Curly cut or curly cut

This type of work is the most difficult. Therefore, it requires a certain skill for high-quality performance.

Work rules:

  • Before you cut ceramic tiles with a grinder, you need to make a marking with a marker.
  • Lay the tiles on a flat surface, fix them.
  • Next, make small vertical serifs, cutting off excess material.
  • At the end, there will be irregularities that need to be processed with an abrasive wheel.

Cutting at an angle of 45 °

In order to do a good job in this case, you need to use a diamond-coated metal circle.

  • Mark a 45-degree cut line with a marker.
  • Secure material face down if possible.
  • Make the first cut with a grinder.
  • Repeat if necessary to improve the result.

Important! When cutting tiles at an angle of 45 degrees, it is necessary not to reach the glaze 1.5-2 mm, that is, only cut off the clay.

Steel rims

This is the most reliable and durable type of grinder tool. The steel discs are diamond-coated on the edge. And their service life depends on its intensity.

Using a steel disc on a tile for a grinder, you can make straight and curly cuts without much difficulty.

Burr

Most often, the grout is done at 45º for joining tiles at 90º corners. But there may also be other degrees (bay window design, flights of stairs, etc.).

For the operation, a grinder is recommended with the possibility of reducing the speed.

  • Preparation of the required element in size. Regular right-angle cutting of tiles in any way.
  • Neatly trims the desired angle. Removal of excess ceramic layer without touching the face layer. At the same time, try to leave a small layer of ceramic (up to 1 mm) in order to avoid damage to the surface coating. There is no preference for fixing the tiles. Most craftsmen hold tiles in their hands. It is more convenient to fix it in the workbench.
  • Manual grinding and finishing of the element to the required form.

Corner trimming followed by finishing by grinding.

Disk selection

Generally speaking, you can cut off in any circle. The question is different, how to cut with a given level of quality, with minimal difficulty and cost. The first disc that comes to hand can leave too many chips, break tiles or fail quickly. But in case of extreme need and without claims for quality, you can cut it like this.

Smaller diamond discs are used in machine tools. When used with hand tools, the likelihood of impacts and jerks increases, which leads to damage to the liner, destruction of the disc.

Diamond-coated discs are available in several types:

  • Segmented. The disc surface is divided into equal segments. Diamond plated on the cutting edge. In the process of work, thanks to the slots, the disc is partially cooled. Note! Such cooling only increases the continuous operation period (up to a maximum of 1.5 minutes). Then you need to take the tool back and let the disk cool down (20. 30 seconds at idle speed). Discs are designed for dry cutting;
  • Solid. Full circle with diamond grit applied to the edge. Designed to work with water cooling. It is convenient to use such a disc to process the edge of a cut tile; segmented tiles are not suitable for this. The cut after such a disc turns out to be more accurate. For cooling, you can periodically wet the tiles, use a spray bottle, or cool more often. The speed of work will be noticeably lower;
  • Combined. Universal blades for dry and wet cutting. They lose in terms of cooling segmented, in terms of the quality of the cut solid.

Example of diamond cutting discs: segmented, solid, combined.

To reduce chips, it is desirable that the height of the diamond spraying is greater than the thickness of the material that is being cut.

When working, it is important to monitor the condition of the disk. At the slightest damage, the disc changes. Otherwise, working with a defective disc will lead to chips, destruction of tiles, or traumatic destruction of the disc itself. (As a variant of minor defects. the appearance of sparking during cutting. Sparking should not be, sparks mean that the metal base is touched, which means that either diamond dusting is emitted or a metal burr or shavings have formed. You can try to grind the defect on stone, plaster, concrete. If sparking continues. it is recommended to change the disk).

There are quite a lot of disks of different quality and different purposes being produced. In addition to the types, thickness and height of deposition, the density of the deposition and the size of the deposited diamond particles are important. For cutting tiles with a grinder, such details may not greatly affect, but when cutting thick floor tiles, dense ceramics, especially porcelain stoneware, the choice of a disc can become critical. In these cases, it is recommended to try several discs on pieces of material and choose the best option.

Shaped cut (round holes)

It is usually the cutting of round holes that is distinguished. But the technique of cutting round holes and any curly cuts with a grinder is no different. The use of a grinder is justified for cutting large holes (over 50. 100 mm). Smaller holes are drilled. A medium-sized grinder (discs under 125 mm) is unlikely to be able to cut a hole less than 100 mm.

Shape cutting technology:

    A cut line is marked on both sides of the tile. It is recommended to cut leaving a line (up to 2. 3 mm), unless, of course, an even cut without chips is required.

We mark the tiles on both sides.

Which angle grinder blade / disk for concrete, plastic, tiles and metal

It is cut along the entire contour on both sides of the tile. Segments are cut through. And extra elements break off.

Finishing trim and sanding.

For a curved cut, you will need a tool with a decrease in rotation speed.

Tile cutting

Before any operations, careful measurements are taken and lines are drawn on the material along which you want to cut off the excess. It is recommended to use markers of a color other than the tile, as a simple pencil does not leave marks on the surface very well. It is even better to carefully scratch the line (for example, with a glass cutter), since a lot of dust is formed and when shaking off, you can simply erase the drawn line.

How to cut tiles with a grinder without chips, with which disc

An angle grinder or “grinder” is one of the few universal tools with which you can do different things. In particular, tile cutting with a grinder. Except when the tile is already glued, there is a tool with which to cut the tile or make a certain cut, the hole is easier and faster than the grinder. Consideration of the reasons for using a grinder and recommendations for using one or another cutting method are beyond the scope of the article. Only the methods of cutting with a grinder are considered here.

It is more convenient to divide cutting methods into several groups:

  • straight cut;
  • curly cut (circles, as a variant of curly cut);
  • burr (cutting edge not 90º).

Different types of cuts: straight, curly, burr.

Straight cut

This is the simplest cut. It can be produced by a grinder of any kind, regardless of the material: porcelain stoneware, ceramics, tiles. At the same time, it is difficult to make a perfectly straight cut with a hand-held electric tool. So they resort to little tricks.

If the quality of the cut does not really matter (it will be covered with plinths, for example), then you can cut it by stepping on the tile or laying it on a rough surface (the tile’s own weight is quite enough so that it does not move during the operation). In any other case, a reliable fixation is required. For this, it is most convenient to use any clamps. With a clamp, a tile or fragment is attached to the surface (table, piece of plywood, chipboard, etc.). For small cuts, you can use a workbench; for cutting along the entire length, the workbench is not very convenient.

Some techniques to improve cut quality:

  • To obtain an accurate cut, a steel tape or steel angle is attached along the line. You can fix it on the tile with the same clamps. Then it is cut right along the corner. The disc is led at a slight angle (10. 15º) to the steel mount.

To obtain a straight cut, the tile is cut along the fixed metal corner.

If there are no peculiarities (something interferes, the line is not visible, etc.), then they always cut from themselves. If you do not have a lot of experience with a grinder, then it is recommended to cut in several passes: the first shallow notch (1. 5 mm) and subsequent ones with approximately the same immersion.

Recommendations for choosing a grinder

It is preferable to use a small grinder with adjustable speed. Low weight will allow more accurate operations. No high cutting power required. For any operations with tiles, a power of up to 1 kW is sufficient.

But the rotation speed during some operations, it is desirable to be able to reduce. Reducing the rotation speed will reduce the likelihood of chips, cracking of the tile.

When choosing a grinder, it is recommended to pay attention to the possibility of speed regulation. The figure shows an example of a speed regulator close-up.

According to the seat, the grinder is optimal for 125 mm discs. In general, you can cut off in a circle with any diameter. Reducing the rotational speed is critical in certain situations, which will be discussed below. The smaller the cutting wheel, the more jewelry operations can be carried out, on the other hand, a small cutting wheel is ineffective to use for a large amount of work. the wheel will quickly grind off. From a powerful, heavy instrument, muscle tension quickly develops and, as a result, accuracy and accuracy are reduced.

In summary, a medium-sized, variable speed tool is best for tiling purposes.

Safety engineering

The angle grinder is a tool with increased risk of injury! In combination with work on tiles, a large amount of dust and debris is added, flying from under the tool disc.

Mandatory use of special equipment:

  • Protective mask (as a last resort, glasses);
  • Protective suit that completely covers arms and legs;
  • Protective gloves or gloves.

It is not allowed to work with a faulty tool (backlash, violation of the case, electrical wires, etc.). It is strongly not recommended to use a grinder without a protective cover (only in very extreme cases, taking additional measures to protect against possible destruction of the cutting wheel).

Perform operations with cutting discs only after physically disconnecting the electrical cord from the mains! And vice versa, connect the instrument to the electrical network only after making sure that the disc is installed, securely fixed, the key is removed.

Do not use defective discs. Before each use, you must make sure that there are no defects on the disc and only then start working.

Round hole: you have to tinker

  • First, you need to apply a marker, with which you will draw the outlines of the required hole on the glossy surface of the tile.
  • Next, straight lines are drawn crosswise to find out where the center of the circle is approximately.
  • Begin to carefully file the grinder in a circle from the inside until you go deep enough.
  • Rotate the tool so that it gradually fits into the circle you have outlined.
  • When the cut turns out to be quite deep, you will also need to cut it crosswise, along the lines drawn in advance, and then carefully get out the four sectors of the circle.

How to make a 45 ° cut

The required size is marked on the tile with a marker and cut in the usual way, that is, at a right angle. After that, the working edge of the disc is sharpened by 45 ° and smoothed with sandpaper.

Steel rims

Steel cutting discs. thinner and more durable. The most expensive varieties are diamond-coated. These discs cut the most durable type of tile. porcelain stoneware.

Three methods of applying diamond chips are used:

  • Soldering with silver solder. These diamond discs have the lowest cost, usually used in everyday life. Disadvantage: when heated, the silver solder loses its strength and diamond spraying wears out quickly. Therefore, the service life is relatively short.
  • Geometric snapping. The edge of the disk is strongly heated by electricity and diamond powder is embedded in it. With this method of spraying, the service life is significantly increased. The price of the disc, in comparison with the previous version, is higher, but for everyday use it is quite acceptable.
  • Soldering with a laser. Expensive heavy-duty wheels that can cut materials of any hardness for a long time. Cost. from 9 to 25 thousand rubles. Used in industry.

Grinder discs

Recommendations for choosing a cutting steel disc for ceramic tiles:

  • thickness. no more than 2 mm: then the cut will turn out to be even;
  • the width of the cutting edge (diamond spraying) is greater than the thickness of the tile;
  • The recommended rotational speed indicated on the disc corresponds to the rotational speed of the grinder.

Steel discs are divided into three types: dry cutters, solid (for wet cutting) and combined.

Stone discs

This variety has the lowest cost, but it has two drawbacks: the discs wear out quickly and have a significant thickness, as a result of which the cut is wide.

For this reason, stone discs are relatively rarely used.

Used attachments

To cut ceramics, you need special discs that are designed specifically for this. Most often, there is an inscription on the circle itself indicating the direction of the turn. The quality always depends on the price. There are the following types of discs:

Stone is rarely used due to its quick ability to grind and spread dust. During the cutting process, you need to control the cutting base. If irregularities are formed on the edge, then the disc should be replaced to avoid damage.

  • Metal diamond circles. In turn, they are divided into solid and divided into compartments. For ceramics, the first type is better. You cannot work with such a nozzle for more than one minute. Take short breaks to cool the instrument. Segment discs are suitable for porcelain stoneware, concrete or stone. This type of attachment has correctly positioned slots that are designed to increase service life.
  • Dedicated wet-cutting discs allow dust-free sawing of tiles by introducing water to the nozzle.

If you need to cut a brick of paving slabs, then only a diamond wheel will help in this situation.

Here are some things to remember:

  • use not only safety glasses, but also headphones due to the increased noise level;
  • the grinder must have a lot of power to cope with the material;
  • avoid dust ingress on the already tiled surface.

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 almost impossible with conventional cutters and saws, and the cut will most likely be uneven and unattractive. An ordinary grinder is best suited, the cutting wheel of which allows you to neatly cut the 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. This task can be handled by an ordinary homeowner who has not dealt with such work and can even cut off a “hog” without the help of a tile cutter.

You can cut tiles using the following tools:

  • special tile cutter;
  • diamond tools;
  • Bulgarian.

The main thing that you need to pay attention to when choosing is the quality of the disc

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 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.

When cutting with a grinder, be sure to take care of protective measures

Be sure to carry the following attributes with you:

  • glasses;
  • mask;
  • thick gloves.

Please note that the selected grinder or grinder must have a speed regulator, since many modern inexpensive tools are devoid of this function. Such models operate at the highest speed, which is why it is impossible to cut tiles with their help.

Segmented dry cutters

Segmented discs received the common name “dry cutters” for their ability to cut material dry, that is, without water cooling. The circle is divided into segments by radial cutouts, which provide efficient heat dissipation and free expansion of the metal when heated. Due to this, the time of continuous operation reaches 1 minute, after which they pause for 20. 30 seconds. The grinder is not turned off for this time. the disk rotates at idle for the purpose of cooling.

The disadvantage is low cut quality, a large number of chips. If the trimmed edge of the tile will remain visible, the cutting is carried out with a margin of 3. 5 mm and then the edge is trimmed with a grinding wheel.

A variety of cutting discs

Today there are many different cutting discs that are available for a specific material. Cutting tiles with a grinder should be done with a stone or steel disc (dry cutter) with diamond chips on the working edges. Dry cutters are divided into several types:

Stone circles are much cheaper than metal discs, but they deteriorate faster and leave a wide cut on the tile. While working with them, it is necessary to constantly monitor the integrity of the working edge, otherwise the disc can prick the material, and then completely scatter and cause serious injury to the user

Therefore, you need to carefully cut ceramic tiles with such a nozzle.
Metal dry cutters allow you to work without water cooling, but no longer than two minutes, after which it is necessary to cool the grinder by idling. It is more rational to purchase a disc with a continuous diamond coating on the working edge.

If, when cutting ceramics, a glowing trail of sparks appears, then it is necessary to fix the protective metal casing, it happens that it skews and touches the disk. If the problem persists, then it means that the steel is licking and you need to clean it on concrete or plaster. Otherwise, the dry cutter will become unusable from overheating.

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 cutting 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 grinder towards himself, only lightly resting his hand on the stand.

Option for cutting with a grinder in pull mode

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 smooth, it seems that the cutting was carried out not with a grinder, but with a tile cutter.

Cutting Bathroom Tiles with an Angle Grinder (Quick Tips) — by Home Repair Tutor

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.

What disc to cut porcelain stoneware with a grinder

Sawing of porcelain stoneware tiles can be done in two ways, it all depends on the thickness of the material and on how complex the seam is to be cut. Since porcelain stoneware is still not granite, but just an artificial imitation of it, two types of discs can be used for cutting:

  • Vulcanite discs based on synthetic superhard ceramics. With such a circle, you can cut thin grooves, corners, trim the edges. In order to cut the expanded clay with a grinder over a length of more than 10 cm, they are not suitable, but they are quite suitable for small jobs;
  • Diamond cutting wheels. With this tool, you can cut seams of unlimited length. The only drawback of diamond is the rapid rubbing of the cutting edge, which will need to be restored and cleaned periodically.

The optimum circle diameter for a grinder is 115 mm, in this case it is easier to control the tool by holding the body with both hands. For a larger diameter blade, you will need to use a more powerful tool, such as a circular saw.

Diamond cutting wheels in themselves are quite an expensive and capricious tool, therefore they try to do most of the work with vulcanite discs, only the most delicate operations, such as trimming and adjusting the plane, are performed with diamond powder.

In addition, discs for cutting porcelain stoneware with a grinder must have a solid edge without a notch or turtle profile. Such a tool cuts well natural granite, rubble stone, but at the slightest attempt to cut porcelain stoneware tiles along the cutting line, a huge number of enamel chips appear on the front surface.

If there is no specific preference for a well-known brand of cutting disc manufacturer, then it is best to buy discs from leading hand tool manufacturers. Simply put. bought a grinder made by Makita, buy cutting discs with attachments manufactured by the same company.

How to cut porcelain stoneware with a grinder without chips

There are two ways to cut porcelain stoneware tiles. The first is to apply a 1-2 mm deep risk along the marking line, and then split the porcelain stoneware into two halves, as 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 a 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 a metal ruler, all the irregularities will immediately become visible. An example of cutting porcelain stoneware with a grinder without chips is given on

Is it possible to cut porcelain stoneware with a 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 porcelain stoneware with a grinder so as to achieve a perfectly straight cutting line.

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

  • A grinder is a hand tool, and often it is necessary to cut the material, as they say, by weight, as a result, the disc 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 lack of cooling of the cutting line. The desire to cut faster leads to excessive pressure on the tool, as a result the circle and the tile itself breaks, not to mention the fact that the entire cutting line 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 with a grinder by weight, then chips must appear

Cutting with a 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 cut correctly with a high-raised 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 grinder has to 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 of the grinder, it is easier to control the cutting line, on the other hand, the tool is in an unstable position relative to the marking, which negatively affects the quality of the straightness of the seam.

Useful Tips

There are all sorts of models of attachments for the grinder on sale, some of them provide connection of the vacuum cleaner nozzle to the protective casing 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 grinder body with both hands, while the left hand should rest on the stand or guide rail, and the right hand is directly moving 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.

How to get rid of dust when cutting porcelain stoneware with a 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 line of movement of the grinder at a distance of 10-15 cm. It turns out not very convenient, since the pipe has to be rearranged, but the dust is removed quite effectively. Immediately after the end of the work, you need to blow out the grinder and collect some of the dust remaining on the surface of the porcelain stoneware.

Cutting porcelain stoneware with a 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 to learn how to cut porcelain stoneware with a grinder without chips. At the same time, control the process at any stage, otherwise the expensive material will go to scrap.

It is best to cut porcelain stoneware using a guide bar as a support for the grinder body
