Rubi - Centering Head and Drill Bit Set (7 Pack)

The tungsten carbide drill bit kit is the easiest and most economical option for drilling holes in tiles. The tungsten carbide drill bit kit includes a spindle and center drill, seven tungsten carbide drill bits measuring 27, 35, 45, 55, 65, 70, and 85 mm, and a convenient plastic case. With the tungsten carbide drill bit kit and a non-percussion electric drill, the professional installer can drill the most common and necessary holes in any tile covering without the need for visible cuts. Tungsten carbide drill bits always work on the unglazed side of the tile, and thanks to the spindle's center drill, 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 material residue. The maximum speed for using tungsten carbide drill bits is 800 rpm. To ensure longer drill bit life, it is important to maintain the correct rpm and apply moderate pressure during drilling. For the best finish, it is recommended not to drill completely through the tile and to break the witness from the glazed area. RUBI is committed to quality.
