How To Cut A 45 Degree Angle

How to cut a tile at 45 degrees? It is quite difficult to wash the tiles at 45 degrees on your own, but you can. How to cut tiles at an angle with your own hands? How do I cut tiles myself at 45 degrees?

Manual tile cutter

The manual tile cutter is popular not only among professional tilers, but also among hobbyists. Many models of such tile cutters are equipped with a special rotary base and a built-in ruler, which allow you to make a high-quality cut of tiles at 45 degrees. After inserting the tile into the tile cutter at a certain degree, it is necessary to align the mark on the tile and on the construction tool. Having lowered the handle down, you need to move it in a direction away from you with slow movements at the same speed and even pressing.

How To Cut A 45 Degree Angle

Slicing without special tools

It is not necessary to grind the tile using special devices. At home, you can easily hand-wash the tiles at 45 degrees. To do this, proceed as follows:

  • On the outer part of the tile (glaze), a line is drawn with a glass cutter;
  • With the help of a grinder, a small groove in the form of an English letter V is formed on the back of the tile, which is positioned along the width of the entire tile;
  • Then you need to gently break the bend of the cut and sand it with sandpaper.


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.


Despite the fact that such a building device is present in almost every home, it is very difficult to cut tiles independently at a 45 degree angle with a grinder.

For a quick and even cut of the tile, it is necessary to install a diamond wheel on the device. In this case, the tile should be placed under the rib with the outside to the bottom. Now the grinder needs to grind off the back of the ceramic tile at an angle of 45 degrees.

From the first time, it will not work to make an even and clean cut. Therefore, after the angle has been formed, it is necessary to repeat the process and walk with the diamond wheel of the grinder along the cut edge. Only in this way will the angle become even.

To form a corner on a tile, it is necessary to choose the right grinder, since not all models can perform the necessary functions. In this case, it is worth purchasing a construction tool from which you can adjust the speed.

Fundamental rules

When grouting tiles, remember that only clay can be cut, not reaching the glaze of 0.5-1 mm. In this case, the corner of the tile will turn out to be nice and smooth, without damage or chipping.

Modern capabilities and the skill of specialists allow you to cut tiles at 45 degrees not only from the edge, but also in the middle of the product. To do this, the tiles must be measured and cut in accordance with the required size, and then cut at 45 degrees. To get a high-quality result, you should seal the cut edge with sandpaper.

How to form an acute angle correctly?

The next step after the process of cutting the tiles to a degree of a certain angle is its worthy use, as well as the organization of a right angle. To do this, the following points must be observed:

  • Using a special building level, you must evenly glue the first part of the tile. Its trimmed edge should slightly protrude beyond the base of the right angle;
  • The second tile should be glued opposite in the same way, the fixing period of the glue at the same time allows you to move and adjust the touching tiles in order to achieve a tight contact.

Before you start facing the corner, you should check the vertical consistency of the wall. Even with the lowest elevation differences, the angle at the top may not converge and turn out to be even. It will be impossible to camouflage or patch up this flaw in the future.

The scope of use of a sawn-off tile at an angle of forty-five degrees has certain limitations. As a result of the cut off clay on the back side, the narrowed edges of the tile become thin and brittle, so they can easily break off.

How to veneer and shape a right angle?

First you need to glue the first tile and set it in level. The trimmed edge will fly out of the plane of the wall.

Then immediately you need to glue the second (reciprocal) tile on the other side of the corner. While the glue is fresh and amenable to adjustment, you need to form a beautiful right angle.

And so we gradually move up, row by row.

An important point!

Before tiling the corner, make sure your walls are vertical.

Because if the walls are at least a little overwhelmed outward, then without steps the corner will no longer converge. And this is not very beautiful, believe me! And you will not cover it up with anything or make up.

Where can’t a chiseled 45 angle be used?

An angle of this type becomes quite fragile due to the thinned (narrowed) edge of the tile, so it is undesirable to use it when facing steps. In the place of the greatest traffic, the tiles will surely beat off, the corner will be chipped, it’s only a matter of time.

The steps are laid with an overlap of the top tile on the end tile (on the riser) or using aluminum corners / profiles.

And in general, before making such corners, think carefully about everything. If there is a big threat of hitting and knocking down this corner, then most likely this is not your option. In this case, you can try using an aluminum corner (but not a plastic one).

How and how to cut tiles at 45 degrees. Tile burr

In order to beautifully revet any right outer corner with ceramic tiles (porcelain stoneware, mosaic), the end of the tile is cut at an angle of 45 and a neat right angle is formed from the two tiles.

A plastic corner is no longer fashionable, not interesting and not beautiful.

Over, it will not be beautiful if you just attach one tile to the end of the other. But this is also very common.

How to trim (sharpen) tiles at a 45 degree angle?

Everyone calls this action differently: washed down, sharpening, trimming, gouging, the Kremlin corner has the same meaning.

For high-quality trimming of the end of the tile at 45 degrees, you will need an electric tile cutter (tile cutting machine) or, in extreme cases, a grinder (grinder) with a disc on the tile.

How to properly trim tiles at 45 degrees?

To make the corner of two tiles look beautiful, when trimming tiles, you need a little do not reach the glaze (0.5-1mm). That is, only clay is cut. If you walk over the glaze (the front of the tile), then it will be torn and chipped. It will immediately catch your eye, it is not beautiful.

We are faced with such a problem about cutting corrugated tiles. But more on that later.

Surely many of you have seen such art, but more often than not everyone thinks that it should be so. And the tile-maker with twenty years of experience assures that it cannot be otherwise.

Even if there is a need to cut the corner of the tile not from the factory edge and you have to cut the glaze, there is still a way to do it beautifully.

First, to do this, you must first cut the tiles exactly (to the desired size), and then, again, before reaching the glaze, cut it to 45. This cut will be much cleaner and more beautiful.

You can also sand the edge of the glaze with fine sandpaper, which will make it even smoother.

Secondly, you can still cut off the corner from the beautiful edge (factory end), and sand the trimmed opposite edge with sandpaper and hide it in the other direction. It will be less conspicuous.

So, for example, we once did when facing a toilet installation. Because the beautiful corner is more important than the bottom seam. Over, it turned out to be very neat too, and if you do not know that it is cropped, you will never pay attention to it.

The easiest way to grinder

It is more difficult to achieve a quality result with a grinder, but, in principle, it is also possible. This is the easiest way to sharpen a 45-degree tile corner with your own hands at home.

The process of grinding and grinding porcelain stoneware is below.

First of all, you must have a good diamond disc for your tiles.

Place the tile on the edge (perpendicular to the one to be cut) and grind the back part (clay) at an angle of 45 degrees.

If it turns out a little uneven, then large coarse irregularities can be passed again with a disc, and in order to get a cleaner and smoother edge, you can use such a (below) grinding attachment with sandpaper or diamond turtles.

Emery discs with Velcro, removed, removed and attached a new one. The very base with Velcro is screwed onto the thread of the grinder. Diamond tips have a much longer resource, but they also cost many times more. If you are constantly laying tiles, then it makes sense to take exactly diamond turtles. If you are doing the first and last repairs in your life, then it is quite possible to get by with emery wheels.

When working with such a thing, you need a grinder with adjustable revolutions (revolutions to a minimum!), Otherwise the edge of the tile will melt and burn, and not be sanded.

You can buy great turtles here!

A miter box will help you to cut the skirting board at an angle of 45 degrees. By the way, do you know how to use the miter box? The specialists of our portal have prepared a step by step for you.

How to cut at a 45 degree angle

Often during repairs, you can face a situation when it is necessary to saw off a piece from a part, at an angle of strictly 45 degrees. Usually, this is needed to connect two parts at right angles, 90 degrees, such as: door trim, plinth, pieces of furniture and much more. An experienced craftsman, professionally engaged in repair work, can often do without special devices, and practically by eye is able to cut the necessary part smoothly and clearly. But if you are a novice repairman, and you have a desire to do the work as efficiently as possible, without damaging expensive parts, then you just need to purchase a miter box a special device that allows you to saw off the material at a given angle without any special tweaks.

To work, you need to have: a miter box, a hacksaw, a protractor with a pencil, a workpiece made of wood, a screwdriver with screws or a clamp.

Self-made miter box

  1. 1. First, you need to assemble the box of the future tool. To do this, it is necessary to drill holes in its side walls, for future fastening with screws and, having smeared the ends of the parts with glue, connect them in such a way that both walls are strictly perpendicular to the bottom and parallel to each other, after which we fix them with screws.
  2. 2. Using a protractor, mark an angle of 45 degrees with a pencil, if necessary, add additional mowing lines for the grooves. The most important part is the cuts, it is best to make them with the same hacksaw blade as you will be cutting products. It is necessary to cut by holding the blade, avoiding strong pressure on the tool, first we cut one side, then the other.
  3. 3. We start processing the material. With a clamp or screws, we fix the miter box on the working surface. At the place of the future cut on the plinth or board, we make a mark. How to cut at an angle of 45 degrees becomes clear if you press it tightly against the side wall and align the mark with the slot on the template. We insert the hacksaw into the groove and cut the workpiece, while the work of the blade is limited to cuts, which allows you to make the cut as smoothly and accurately as possible.
  4. 4. Before sawing the skirting board, make sure that the corner of the room is really straight and, if it is not, you need to adjust the cutting angle of the workpiece. To do this, measure the inner corner of the wall joint, and divide the result by two. If you do not have a professional rotary miter box that can change the cutting angle by the required amount, then to achieve the result, you need to saw additional grooves at the desired angle in a homemade miter box. This way you can cut the skirting board for the most accurate alignment.

Now you know how to cut a workpiece at a 45 degree angle. Perhaps the time has come to move from theory to practical action. The team of the portal is sure that you will definitely succeed. Stay with us!
