Tungsten carbide drill bits are the easiest and most economical option for drilling holes in tiles. With the tungsten carbide drill bits, the spindle and centering drill bit (ref. 04992), and a non-percussion electric drill, the professional installer can make the most common and necessary holes in any tile covering without the need to make visible cuts.
Tungsten carbide drill bits always work on the unglazed side of the tile, and thanks to the spindle's centering drill bit, the use of a guide is not necessary. The drill bits are dry-cutting, but it is recommended to lightly moisten the tile to reduce dust generation during drilling. The average life of tungsten carbide drill bits is 100 holes and ALWAYS depends on the tile type, its thickness, as well as its proper cooling and use. The drilling depth of tungsten carbide drill bits is 18 mm.
Before drilling again, ensure that the drill bit is clean and free of any obstructions or residual material. The maximum speed for using tungsten carbide drill bits is 800 rpm. To ensure a longer drill bit life, it is important to maintain the correct rotation speed and apply moderate pressure during drilling. To achieve the best finish, it is recommended not to drill completely through the tile and to break the sample from the glazed area.
