How to properly cut a tile at an angle of 45º

The process of laying ceramic tile includes many aspects that at first glance is not always and not everyone notice. But it is worth to start repairing, and we are immediately confronted with the peculiarities of this type of finishing. Tiling a wall or floor plane with tiles is not too difficult. It is more difficult to deal with outside corners. Window and door jambs, recess shelves, stairs, etc.д. There are three options:

A detailed description of how to cut tiles with an electric tile cutter has already been given in a previous article. Now it is worth noting that this device makes it possible to cut tiles at an angle. Let’s take a closer look:

The following tools will be required for the work:

We make a marking with a lead pencil on the masking tape glued to the tile (thin, clear lines on a light background are clearly visible).

Tilting the frame of the machine at 45º, make the cut.

Get the 45º angle. The cut is even, but not perfectly smooth.

Using an angle grinder and a “turtle” grind the cut (at low speed).

If you do this job right, you’ll get a smooth, even 45º cut at the end of the tile. If the two received fragments of tiles are connected. a right angle is formed.

After laying the tiles, the outer joints, as well as all others, are grouted with grout.

Tile cutter

We are talking about professionals who do this kind of work regularly. The most popular are two models of the company Feida:

Despite the fact that it is produced by Chinese companies, they have a high quality and precision cutting.

With their help absolutely any angle of tile that will be necessary for laying can be done. Most often it is 45 degrees and is popular.

Also among the firms, Einhell and Proton are reliable.

Many problems here arise when working with wavy tiles, when the tile cutter touches the glazed part. It becomes scraped and “torn”, which noticeably spoils the appearance. Work with tiles will usually be performed by professionals. After all, no one will buy expensive equipment for personal use. Such work is carried out very rarely:

When ordering a service from a construction firm, it is best to clarify its status and experience in this area beforehand. It’s not uncommon for large quantities of tile to be “destroyed”. Each nuance is worth to prescribe in the contract to be concluded in advance, so that later there will be no problems in the proceedings.

The quality of the cut at 45 degrees with a professional tile cutter will be immediately noticeable to everyone. In addition, the work is carried out in a short time, which allows you to start laying tiles almost immediately. Such design of tile corners will be appreciated by every owner of a room where tiles will be glued.

Using sandpaper

This material most often come to the rescue, to hide the inaccuracies of preliminary work, when the glaze is damaged or there are chips. In addition there is another option of using sandpaper.

Instead of professional tools and the need to save the layer of glaze, on the front part is made an incision with the help of glass cutters. After that, the back side of the angle grinder makes a notch in the form of the letter “V”, which must be made across the entire width of the tile. All that remains is to break the element, and the remaining work is completed with sandpaper.

Some craftsmen try to reduce the cost of the work, using only regular sandpaper. In this case, the corner of the corner tiles under 45 degrees is performed independently, watching the state of the clay and the glaze itself. If you overdo it, the damage will affect the tile, therefore, you will have to spend money to buy similar material. Significant importance will also play the coarseness of the sandpaper itself, which should vary.

For a precise alignment, two versions of the material to create a bevel of 45 degrees will do:

The first numbers will be used as a rough tile fitment, and the second to create a really flat and high-quality surface as best as possible. Only after that you can put a tile on the corner, without fear of criticism from the outside. If you follow the requirements and recommendations from the experts when making 45-degree cuts, there will be no questions about how to design the corners of the tiles. In the end, you can even say that the resulting tile without corners.

What tools are used for grinding tile ends at 45 degrees?

Cutting porcelain tile at 45 degrees can often be referred to as filing, sharpening, trimming, barking. In this case, the meaning in each case is put the same. The end of the tile is grinded so that it changed its right angle to an angle of 45 degrees.

A similar operation can be performed using different tools. But the best result and the highest quality of grinding the ends is achieved with the electric tile cutter, which is a special device for cutting and sharpening the ends of tiles. In extreme cases, you can use an angle grinder with a special wheel for cutting tiles. However, in this case, the master must have sufficient experience and skills to do the work qualitatively.

In any case, it is worth taking a closer look at each of the methods of cutting porcelain tiles and tiles at 45 degrees.

Tile cutting by angle grinder

Cutting tiles at 45 degrees with a grinder is a rather time-consuming and technically difficult process. Not every experienced craftsman will be able to accurately trim the face of the finishing material. True, with the proper skill and experience with it can still cope. In fact, the use of angle grinder. this is the most affordable way to trim tiles at home, as many homes have a similar tool, which cannot be said about electric devices for sharpening or cutting ceramic finishing materials.

Also: Hole in the tile for a socket: how to cut correctly?

Before you start using an angle grinder, you should make sure that you have a good diamond disc, suitable for cutting ceramic tile and porcelain tile.

The presence of diamond spraying on the edge is obligatory

The porcelain tile is placed on an edge, and then the other edge, which is in a perpendicular position, is gently sharpened with a diamond wheel to an angle of 45 degrees. In this case it is worth remembering that the back side of the tile should be trimmed, not the glossy side.

If the first time the surface is not perfectly flat, it can be smoothed, once again passing the diamond wheel. Also for this purpose can be suitable belt sander. But not everyone has such a tool at home. Therefore, as an alternative, you can offer to use a wooden bar, wrapped with sandpaper.

It is also possible to use sanding discs with velcro. Such nozzles are simply screwed on the angle grinder, and then glued to the sandpaper. You can use diamond bits that have a longer life and better performance. True, they are much more expensive than ordinary sandpaper on velcro.

When finishing large areas it makes sense to spend money on diamond nozzles. If we are talking about finishing a small section of the wall, such as the apron in the kitchen, then we can be limited to the use of abrasive circles.

Important: When using diamond tips for the purpose of filing porcelain tiles under 45 degrees will require the use of angle grinder with the function of regulating the speed, while the speed must be set to a minimum.

Electric tile cutter

Can be installed without legs The tile cutter is a machine for cutting tiles at 45 degrees, as well as for its longitudinal and transverse cutting. Such a device has a water cooling system. In addition, water helps to remove almost all the dust that occurs during the cutting of ceramic tile or porcelain tile. The main advantage of the tile cutter is its accuracy. It cuts in a single, pre-set path. This eliminates the influence of such factors as shaking hands of the master. As a result, the cut is as even and accurate as possible.

Tile cutters can cut at virtually any angle. However, often masters cut tiles at an angle of 90 degrees or 45 degrees.

What to cut a tile at an angle of 45 degrees

Electric tile cutter

Electric tile cutter is an expensive, but necessary tool for a lot of tile cutting. Makes a straight cut and mitre cuts at a selected angle. Can be set from 0 to 45. In practice, most often the tiles are trimmed at 45 degrees. Quality models are equipped with a cooling system. Thanks to this, the tile and the tool are not at risk of overheating and the dustiness of the workplace is reduced. Water flow does not affect the quality of the cut.

Consider buying an electric tool if you have to trim hard and expensive material. porcelain tile. The following models are the most popular:

  • Zubr EP-200-1000S (Russia). stationary floor tile cutter. The machine is expensive (21-22 thousand), is designed for professionals and allows you to saw off tiles of any thickness.
  • Zubr EP-180-600H (Russia). compact table model. It is used for straight cutting and beading tiles at an angle from 0 to 45 degrees. Characterized by low noise level and absence of dust: water is supplied to the place of cutting. Reasonable price (4000 ) can be attractive for beginners.
  • Models Feida TC 200 and Feida TC 250 (China). help to accurately cut the high quality angle from 0 to 45 degrees.
  • Tile cutting machine Einhell TH-TC 618 (China). can saw and make beveling of different ceramics, provided that the depth of cut will not exceed 22 mm.

If you cut the tile a little less than 45 degrees, it will be easier to form a right angle.

angle grinder

It is not rational to buy an electric tile cutter for work in one apartment. Qualitatively cut ceramic tiles under 45 degrees, you can use an angle grinder (angle grinder). It is easier and faster to perform the work with a diamond disc. The edge will most likely be uneven. Such defects are ground with turtles. If the amount of work is one apartment, you can use a cheaper option instead: replaceable sanding discs with Velcro.

  • BIZON 0512003, thickness 1.8 mm;
  • Union 9020-04-150x22K, h = 2 mm;
  • Expert (180×25.4/22.2 mm) PRACTICE 034-793 (for porcelain tiles);
  • Professional KEOS DBP01.200 on porcelain tile (180×25.4/22.2).

The quality of work depends on the type of nozzle on the angle grinder for the final stage of cutting at 45 degrees. A good result provides a diamond wheel (flexible, grinding) AGSHK 100 0 “Turtle.

Working with a manual tile cutter

This option is very popular among professional and amateur tilers. Buy this tool is not difficult, the price depends on size, reliability and special accessories. If the tile cutter has a rotating base and a built-in ruler to make a 45-degree incision, then the price will be decent.

Try not even to look at the cheap model, you will spend money in vain, because they have a bad pressure and a weak foundation, so most of the time the tile breaks wrong.

Tips for working with the tile cutter

We insert the tile into the tile cutter, combine the marking on the tile and a special marking on the tool. Lower the handle and move it smoothly away from you. The speed should be the same, the pressure. even, then the glaze will cut with the same depth. One cut with the roller is enough. If the motion is repeated several times, you can get poor quality scrap.

The tool is equipped with special feet that, when lowered, break the tile into pieces of the desired size. The main thing is to press the lever sharply. All tile cutters, without exception, have a platform with a metal knoll and soft pads.

When you press the claws on the edge of the tile, the cut is under maximum pressure. With the correct alignment of the cutting line and the pad, the tile will split very evenly.

From words this process can be not quite clear, especially for beginners. It’s better to see and understand how to cut tiles with a tile cutter properly.

Cutting a tile with an “L

The tile cutter is designed only to make a straight cut, so if you need to make an L-shaped cut, you will have to work a little harder. The easiest thing would be to cut the tile into two pieces, and then one of them again and when laying them folded into an L.

And as a result, you get an extra seam that is not needed, which catches the eye.

You can go another way. the short side is cut with an angle grinder, long. tile cutter.

This method is also suitable for cutting outer corners, the main thing is to correctly mark and take away about 5 mm of the grouting seam a slight indentation from the wall.

There is one more way: the cut on the glaze surface is made with the help of any available cutting and piercing object, and then the excess is broken off with the help of pliers. To process irregularities we use sandpaper. In this way you can make rounded cuts, which are put near the risers.

Cutting porcelain tile

Everyone knows that porcelain tiles are one of the hardest materials used for producing floor tiles. The method of cutting it is the same as for standard tiles.

Floor tiles are often less amenable to cutting than porcelain tiles. This is especially true for tempered tiles, where it is almost impossible to see the notch on the surface of the glaze. Often, even with a diamond disc, it is not possible to make an even cut. In this situation, take an angle grinder, saw a groove of 2 to 3 mm on the back side, which will be the place of the break.


To make a high-quality and even cut without chips and cracks is possible only with the help of special devices, each of which has its own advantages.

Electric tile cutter

The main advantage of this tile cutter is a clear and high-quality cut on tiles, which is carried out in two directions: an ordinary straight cut and a special cut at an angle of 45 degrees. By turning the cutting wheel at an angle to the part of the tile to be cut, it is easy to make a cut from 0 to 45 degrees. The electric machine may have a water feed function, due to which there is less dust emission, or it may have a conventional design. However, both versions of the devices provide the same quality of work and guarantee the cutting of a large volume of tiles in a short period of time.

In the case of concave tile cutting, the electric tile cutter does not repeat the concave deflection of the product. Therefore, you can cut only the back side, so as not to hurt the enamel on the front. This is especially true for porcelain tile.

  • a special painting tape;
  • a simple pencil;
  • a small ruler;
  • tile cutter;
  • Angle grinder with adjustable speed revolutions.

On the part of the tile, where the cut will take place, it is necessary to glue a masking tape. Use a pencil and ruler to make the necessary marks. Then place the tile on a specific section of the appliance at a 45-degree angle. On the principle of a circular saw, the tiles are cut with a diamond band. In some models, during the cut, water is applied, which protects the tile from melting and washes away the dust.

If the glaze on the outside of the tile is damaged, the cut will be unsightly with cracks and scored edges, which will have a sloppy appearance when laid side by side. Therefore, when working with an electric tile cutter, it is necessary to carefully remove only the clay layer.

Professional secrets of experienced tilers:

  • With a tile cutter it is necessary to achieve an even cut;
  • then form the necessary angle on the back side of the product;
  • The glaze, which was caught in the working process, is grinded with sandpaper.

Manual tile cutter

Handheld tile cutter is popular not only with professional tilers, but also with hobbyists. Many models of such tile cutters are equipped with a special rotating base and a built-in ruler, which allow you to make a quality tile cut at 45 degrees. Inserting the tile into the tile cutter at a certain degree, it is necessary to combine the mark on the tile and on the construction tool. Putting the handle down, you need to move it slowly with equal speed and even pressure in the direction from yourself.

angle grinder

Despite the fact that such a construction device is present in almost every home, it is very difficult to make a cut of tile under a 45-degree angle with an angle grinder yourself.

For fast and smooth tile sawing, it’s necessary to install a diamond wheel on the device. The tile should be placed under the edge, with the outer side facing down. Now it is necessary to grind at an angle of 45 degrees the back side of a ceramic tile with the angular grinder.

It is not possible to make a clean cut the first time. Therefore, after the corner is formed, it is necessary to repeat the process and pass the diamond wheel angle grinder on the cut edge. That is the only way to make the angle even.

To form a corner on the tile it is necessary to choose the right angle grinder, because not all models can perform the necessary functions. In this case it is worth buying a construction tool, which can regulate the speed.

At the beginning of the work, you should set the minimum speed at which the edges of the tile will be ground, not burned.

The disadvantages of an angle on a tile sharpened at 45 degrees :

The corner becomes more vulnerable to impact. Especially if it is on a passageway. It is enough to hook the slope with an empty metal bucket, so that a piece of the drained corner on the tile, flew off. The work becomes more time-consuming, and thus more expensive.

To snag such a corner can be anything, even a harmless belt buckle of a trouser belt:

Opinion of craftsmen about the cut of tiles on the angle at 45 degrees.

You can also prepare a 45 angle on the tile with an angle grinder. Lots of dust. The wrong quality. But really. The main thing is cheap and always possible.

It is particularly important to indicate the correct angle when laying decorative stones. Often the corner elements for such products are not provided or are not available. Cutting a stone at an angle under 45 degrees is the only way out of such a situation.
