For this, special drills are made for tiles, which are of different types.

Today you can purchase the following types of drills for tile:

With their help you can simply make holes for dowels, which serve as a fastener for the installation of various items. Drills can be used to work with porcelain stoneware, but they wear out quickly. Since their cost is quite low, they are well suited for small jobs.

Characteristic features of such drills:

• high efficiency;
• resistance to wear;
• hole depth - up to 12 mm;
• affordable cost.

Such products are used for working with simple tiles and porcelain stoneware. The main difference is 1-sided sharpening with an acute angle. This allows you to work quite quickly and efficiently.

They are also called "ballerinas", because during operation they spin and are like the movements of a ballerina. They are used to work with different types of tiles, while the diameter of the holes can be 30-90 mm. The product consists of a main and additional drill, a cutting insert. Work with him at a small speed without much pressure. So it will last much longer.

Sometimes you need to carefully drill a large opening for the pipe, outlet or other purposes on the tile. In this case, use ballerinas or crowns.

The ballerina consists of several components, the main one is a cutting drill. When the center part is fixed to the drill, the cutting part is driven in a circular motion and breaks the working surface. This product is best used when you do not need non-standard openings or grooves. The drill must be used only without impact function and with a slow speed, to avoid damage to the tile. Also, when the device is operated at high speed, the ballerina can be damaged. The disadvantage of the product is that with its help it is impossible to obtain an opening with a flat edge.

But with the help of crowns you can get a surface with almost perfectly flat edges. The device may consist of a centering part or without it. If this is available, then drill a hole is fairly easy, as it sticks to the surface being treated and does not allow the crown to move over the surface. Crowns can be drilled as a simple tile, and granite, stone, marble.

Today, you can purchase the following types of crowns for drilling large holes:

1. With diamond spraying. They allow to make grooves in the sizes of 10-70 mm, but there are products and the big sizes. Work with them necessary in the machine with water cooling and purchase with the centering part. Drilling them can be different tiles and stone, but when working with a second material, the product quickly wears out, since it is quite hard. Drilling speeds should be within 200-500.
2. Carbide-tungsten. They are great for working with tiles, porcelain stoneware, brick and stone. As a result, excellent grooves come out, which can be used to attach various shelves, sockets. In the kit there are 4 different crowns.

There are also universal drills used to create any holes in various materials, natural or artificial. Such products have a deep spiral along the sides, through which dust and other materials are removed from the hole. They are made of special steel. The special sharpening technique makes such drills as durable and effective for working with materials of any density and hardness. You can sharpen a drill bit by yourself.

Since any tile is a fairly fragile product, it is necessary to approach it thoroughly. First you need to choose a working tool. If one or two small holes are required, it is preferable to use a hand drill that does not vibrate during operation. But not everyone suits this option. Then a manual drill without impact function is used.

The choice of drill is decided depending on the upcoming work. Spearheads are best used when necessary to make small holes. When making a purchase, you need to pay attention to the fact that the drill bit should be harder than the working surface. Experts advise choosing products with diamond coating. And although it is somewhat more expensive than other types of drills, high quality makes it possible to use it when performing a large amount of work. And that once a year to make a couple of holes, you can buy an inexpensive drill with a winning tip.

Improper drilling technology can damage tiles or other materials.

When drilling deep holes, surface heating is possible. It is therefore necessary to stop work for short periods of time, wet the drill and tile with water. The instrument is then disconnected from the mains.

Since the tile has a slippery surface, it is not always possible to make a hole the first time where necessary. For this, there are the following tips:

1. At the marked point, you can make a small groove with a hot tap or file.
2. You can paste paint tape on the tile.
3. Correction pencil for the office puts a special mark, which will have a slight roughness.

It's easier to perform drilling on an unfinished tile. For this, it is soaked for about 30 minutes in water to avoid splitting. The drilling itself is done on the reverse side, where there is no glazed spraying.

Porcelain tiles are much stronger and harder than plain tiles. The general technology of drilling it is the same, but with some nuances. So, to work with it, diamond drilled drills or crowns are used, manufactured by the diffusive-vacuum method. Such products are extremely durable and resistant to wear. Drilling is a simple drill or perforator without the function of impact.
