When laying tiles, the main difficulty is not trimming, but drilling holes, especially under the flush plates. For this, there are special diamond-coated bits. But even their presence does not guarantee getting the hole exactly in the right place, since they tend to slip to the side when starting drilling. In this regard, we will consider how to use a crown in order to drill exactly according to the markings, and how you can do without it with a conventional drill.
1. Drilling with a diamond core bit
If you use a core bit with a center drill, it deepens and prevents slipping. When working without it, you need to draw the outline of the hole on the tile, circling the crown. The easiest way to do this is by gluing masking tape, since a pencil or regular felt-tip pen does not write on the glaze.
Then we start the rotation of the crown, and put it to the edge of the hole at an angle. Its corner will make a notch that will prevent slipping.
Then the tool will smoothly align.
You need to drill the glaze, getting the shape of the hole. Then water is poured into it. It will cool the crown, which will extend its service life. In addition, there will be no dust in this case. Water is added and when a center bit is used.
2. Drilling with a thin drill in tiles
If you need to drill just a couple of holes, then buying a crown for their sake is impractical. In this case, you can get by with an inexpensive thin tile drill. Also draw the outline of the hole by gluing masking tape.
Then, in a circle, we make a perforation with a thin drill, trying to retreat between them as little as possible. At the same time, the drill is constantly dipped in water so that it does not overheat.
Then we drill the walls between the holes at an angle. After that, the tile inside the circle will fall off. Protruding notches can be broken off with pliers.
Grind the ragged edge of the hole. To do this, we wind sandpaper on the pipe, and level the contour with an impromptu file.
As a result, we get a qualitatively even hole for mounting a socket.
