Cutting tiles with an angle grinder: how to make a cut without chipping?

When installing ceramic tiles, it is often necessary to cut it in a certain way. To solve this problem is a special equipment, which includes all the well-known angle grinder (angle grinder).

Cutting tiles with an angle grinder is the most popular way to perform this type of work. In order to cut a tile in a certain way, use a tile cutter. The tool is represented by two types: manual and mechanical. But its price is quite high. Buy it, mainly professional finishers for constant use. For ordinary citizens, such a tool as an angle grinder is more popular. It is regarded as a multi-tool and helps with many household tasks. It can be found in almost every home. If the owner of the room himself is engaged in tile installation, it is advisable to use this tool. Unlike any tile cutter, the angle grinder allows you to make even holes of round shape, in the absence of a special attachment for a drill bit (crown).

Briefly about the types of tiles

To cover the walls and floor are used mosaic tiles, glazed or porcelain tiles. In the case of the first, as a rule, it is enough to have a construction knife or scissors at hand to cut the grid of the fabric formed at the factory. For cutting larger samples requires an electric tool or a handheld tile cutter. Let’s consider what you need to know about the facing material before sawing tiles with an angle grinder.

Ceramic products are characterized by high hardness and durability. This can be a solid or two-layer design (with a decorative coating). The main disadvantage of materials is their brittleness. From a point mechanical load, the cloth can break, and the edges can chip during cutting. It is important to consider these points when choosing a tool.

One of the main components of success in cutting porcelain tile with an angle grinder without chipping is the quality of the disc. Since this type of tile is considered to be a very strong material, which is harder than even natural granite, it is necessary to use diamond blades to cut it.

Recommendations for choosing a diamond blade:

  • Choose a disk specifically for the material you are going to cut (on the disk may be written hard granite, hard ceramic, porcelain);
  • blades must have a smooth cutting edge;
  • The thinner the disc, the lower the probability of chipping while cutting;
  • The higher the height of the diamond segment, the longer the disc will be in service;
  • to buy it is necessary to know the parameters of the angle grinder, namely: what size (outside diameter) of the disc is suitable for the machine, the diameter of the planting hole, non-compliance with these parameters is unacceptable;
  • it is necessary to pay attention to the recommended RPM during work, compare these data with the grinder’s capabilities.

Due to the appearance of new varieties of porcelain tile on the market, it is becoming more difficult for manufacturers to develop a disc that will fit all types equally well, so it often happens that to achieve optimal results, the craftsman has to try several options.

When working with a grinder, safety precautions must be observed, so protective equipment must be purchased in the first place:

  • safety glasses;
  • Respirator. during work a lot of dust is formed, which, when inhaled, settles in the lungs;
  • Wear protective clothing, headwear;
  • headphones, earplugs.

Do not neglect protection even if you need to cut a single tile into pieces.

Many people ask whether it is possible to cut porcelain tiles with an angle grinder without chipping? Unfortunately, chips will always be there, but their number and size can be reduced to a minimum, following some recommendations.

Technology and rules for cutting porcelain stoneware:

  • To put the tile on a flat surface, under it (to prevent damage to the surface) to put a foam plastic, foam plastic or other material;
  • Pre-apply the line for the trimmer, on which the cut will be made.
  • To decrease the possibility of chips it is recommended to put a masking tape on the place of cut and run a fishing line for a trimmer on it.
  • To reduce dust in the workplace, it makes sense to use a vacuum cleaner, which will immediately absorb it.
  • Cutting porcelain stoneware is carried out from the front side, as the output of the disk gives the greatest number of chips.
  • For accurate cutting of thick porcelain tiles you can use a metal corner, which is fixed along the cutting line clamps, along it is carried out cutting angle grinder.
  • The cut should not be made exactly along the pre-plotted line, but a little to the right, so that the line for the trimmer remains visible, possible irregularities then grind to the marked line, thereby obtaining the desired tile size.
  • The grinder should be moved in the “away from you” direction.
  • If there is no need to make a perfectly even cut, or it is a thin tile, you can not saw it to the end, and make a cut, then break along the line of notch.
  • To reduce chipping it is important to make the cut in one pass.
  • After cutting, the chipped ends can be grinded.

How to cut porcelain stoneware with an angle grinder

In the process of tiling is not always possible to cut porcelain tiles with a mechanical tile cutter. In such a situation, an angle grinder comes to the rescue, and the quality of the cut depends on the quality of the wheels for the angle grinder. Sometimes porcelain tile breaks when cutting, and sometimes there is red-hot metal at the tip of the cutting disc. That’s why it’s best not to skimp on good wheels. In addition, be sure to consider the following points.

It is preferable to cut tiles from the front side. That way, fewer splinters will be produced. Cutting from the other side, on the other hand, will not only result in considerable splintering, but also a different cutting line.

Power angle grinder is not the main indicator for cutting porcelain tiles. Revolutions are much more important: the more they are, the more accurately the cut is made. Particular attention must be paid to the rotating shaft and the quality of its bearings. If the alignment is not correct, you can’t avoid vibrations and splinters as a consequence. If the turns are large, bearing failure is inevitable.

To avoid splinters, the roller of the tile cutter first draws a line for the trimmer, on which the cutting will take place. Thus the wheel cuts through the upper layer of the tile, which allows you to do without chipping. However, a narrow band will not break the tile cutter completely, so without an angle grinder can not do. The main thing is. Be careful not to hit the trimmer line marked on the cutting wheel. Next, the separated part is finalized with a bar, which is previously wrapped with a light sandpaper. In any case do not need to use coarse sandpaper: it will leave chipping on the enamel. The grit of the paper determines the cleanliness and evenness of such work.

Don’t forget safety precautions! Cutting with an angle grinder requires the mandatory use of safety glasses. Flying splinters at high speed can get into the eye and stuck, and to get it out by your own efforts is very difficult. when cutting, use the lower third of the wheel, do not go below the half. Otherwise the turbine threatens to pop out, which can lead to the most unpredictable consequences.

In addition to increased injury, one of the main disadvantages of cutting porcelain tiles with an angle grinder is the formation of large amounts of dust. This makes it impossible to use this method during finishing work. wallpapering, painting, etc.ะด.


If an angle grinder is used for cutting, before the procedure it is recommended to check the tool for damage and performance. You need to insert a disc to work on cement or metal. There is certainly a difference between the two, but it is insignificant.

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

And we shouldn’t forget the personal protective equipment. This means that you should also wear a hat on your head, protective gloves on your hands, clothes on your body and goggles to protect your eyes. The latter is probably the most important. After all, dust, small splinters at a very fast rotation of the disc angle grinder can get into the eyes. And this can turn out to be a dangerous injury. Therefore, you should think about your own safety in the first place.

Tile cutters

For the shape cut, you need pliers. They don’t actually cut the tile, but break off small pieces from it. Because of this, the line for the trimmer turns out uneven and requires additional sanding.

The tile trimmers are designed to make material for mosaics. For ordinary repairs, they began to use them later. Pliers are generally similar to ordinary pliers, but they have a diamond roller on the bottom and so-called “jaws” on the top.

To obtain a circular notch, a marking is made, and then small pieces are selected. If you need to make a straight cut, then first a roller cut is made on the glaze. Then the roller is put under the bottom, and the jaws on top. When you press the handles, the tile breaks along the line.

Also pliers are very useful if you need to cut from the tile trimmer line less than 5 mm. Other tools can’t handle this kind of work. It is better to use a construction level, so that the masonry does not go obliquely on the wall.

The best cutting wheel for cutting ceramic tiles in 2013.

“The “best” not in the price-quality comparison. And just the “best” in quality and cutting speed. At one time, this place was taken by Bosch. But, nowadays, their price is almost twice as high as similar products of the corporation “Di-Star” and the quality of the cut is worse. Maybe their quality is still the same, but there were just more high-quality products.

Products of Di-Star appeared on Ukrainian market long time ago (1998).). these were cutting circles affiliated company “Ukr-Diamant. Such a circle could work for more than a year. But were high and more popular were other manufacturers. Currently, the cutting wheel for cutting with an angle grinder 125 mm in diameter costs about 20, and cuts ceramic tiles with almost no chips.

How to turn an angle grinder into a tile cutter

It is not always convenient to keep the angle grinder on weight and do all the work entirely by hand. In order to improve the quality of the cut, you will need a helper. However, it will be much more rational to turn a regular grinder in the analogue of the electric tile cutter.

We found out how to properly cut ceramic tiles with an angle grinder. The same principles of work remain the same for the tile cutter, but you have both hands free. Let’s look at what you need to do to improve this tool.

First choose a suitable location for the machine. The base of the future tile cutter can be made of sheet metal, in which a groove will be cut for deepening the blade. All work will be carried out on this line, besides, by such a mark will be much easier to navigate.

The most important step. fixing the angle grinder. In order to fix the tool in the right position it is necessary to use special clamps. Their counterpart can also be made by yourself, but there is a risk that the fixing bolts will tear during the work.

For frequent use and convenience angle grinder can be fixed by turning it into a tile cutter

This version of a homemade electric tile cutter can be improved by adding a reservoir of water and a wet cutting nozzle. This will help to avoid dust and cool the tool.

After fixation of the angle grinder a test sawing can be performed. The principle of operation is as follows: the tile is laid on the marks, the angle grinder is turned on and the disc is slowly lowered. The tile will be sawed on the front side, and it is necessary to feed it from yourself.

If the work is done correctly, you will get a ceramic tile cut in two with neat edges, without chips, cracks and nicks. The final look of the tile can be given with fine sandpaper.
