Drilling a slippery surface

Drilling on slippery surfaces such as ceramic, tile or marble, can become a fairly complicated task

Drilling a slippery surface

An teas to try drilling a slippery surface and make hole in all places less where did you decide to do so in principle, you will learn certain tricks that we can take into account to make this task simpler.

A good strategy is to mark the place where you want to make the hole with an awl or nail, so put the bit in that place you have the brand and does not move.

Another option is to place insulating tape fabric in the shape of cross on the place where you want to drill, supporting the bit about tape not will run, since the surface is more porous.

In both cases, you always have to start drilling at low rpm, and not do too much pressure with the drill to avoid splitting.

How do I drill tiles?

With all its advantages, tile has a rather significant drawback – this material is very hard and at the same time fragile, so the processing, which can not be avoided in the process of repair, is quite difficult and requires skills.

Sometimes the need to make a hole in the tile to fix the wall decor or plumbing turns into a real test, and if the drilling rules are not followed, only cracking and damage to the material can be achieved.

How do I drill floor tiles?

Floor tiles are easiest to drill, as they are thick and the effort is directed exclusively in one direction, which increases the accuracy of drilling and minimizes risks. A successful result depends on:

selection of cutting and drive tools;
holding the drill bit in one place;
compliance with drilling techniques.
For drilling tiles, special diamond-coated drills are used, but if, except for the installation of a floor toilet, nothing else is expected, then for the sake of two holes it is not worth spending money on an expensive part.

This can be done with an ordinary drill for a stone with a winning solder.

The main difficulty is to fix the drill on the slippery surface of the glaze, for which you can seal the intended drilling site with a plaster. Drilling should be started at low speeds of the spindle and after passing the glaze smoothly go to high speeds.

In no case should you use the perforator mode while the tile body is being drilled, otherwise it will crack. It is switched to after reaching the concrete surface to drill a recess for the dowel.

All this time, the drill should be strictly at right angles, so as not to touch the edge of the hole with its cutting surface.

How to drill floor tiles?

For drilling, you definitely should not use a mechanical drill, although you can find such tips, even one hole will require a lot of force, while it is quite difficult to observe the straightness of the drill.

You can use both a household electric drill and a professional one, but you should not use Soviet-made drills, on such models there is no possibility of a smooth start of the engine.

The greatest difficulty is drilling a layer of glaze, the drill cannot be fixed in the right place. To do this, you need to screw the passage site, using a hardened screw, slightly hitting it with a hammer several times, this is quite enough to destroy the glaze.

You can also stick a medical patch, which will easily hold the drill in place. Drilling begins with low revolutions, but only in the drill mode, after passing a layer of glaze, you can reach the maximum speed.

After the drill comes out of the tile on the concrete, if drilling needs to continue, the tool is transferred to the perforator mode. If you need to make a large number of holes, then the drill after each pass must be cooled in water.

Cutting tool for large holes

When it is necessary to drill a hole to output electrical wires or secure equipment, drills can be used. Well, what to do if you need to remove a water pipe through a tile or make a hole for an electrical outlet?

As a more expensive option, diamond crowns are used – they have a fixed size, so it is advisable to purchase such a tool in a set, which includes crowns with different diameters.

Basically, it will be needed by those who are professionally engaged in repair work. In order for the crown to last a long time, drilling is performed at the lowest speeds, while it must be cooled often. The crown is used for both laid and not yet fixed tiles.

Ballerina – has a lower cost, so it is advisable to purchase it even for a home set of tools. Unlike crowns, it can be used to drill different diameters of holes, but only on tiles that have not yet been laid.
