Processing instructions:
Always use tile drill bits in combination with a centering device. This guarantees precise positioning and prevents slipping on the workpiece. In addition, the risk of cracked tiles can be minimized by using the centering device. It must always be cooled with water when drilling. Water cooling increases the lifespan of the crowns many times over. The best solution for controlled water supply is the water flush head. When working with water cooling, only use cordless screwdrivers. Immediately after piercing z. B. Continue drilling tiles or fine stoneware depending on the surface with a normal hammer or stone drill. If the drill bit is stuck on the water rinsing head, it can be loosened using 2 open-end wrenches (drill bit SW 22, water rinsing head SW 10).
Speeds: 1,500 - 3,000 1/min depending on the drilling diameter. The larger the drilling diameter, the lower the speed you should choose

Characteristics:
High-quality, full-surface diamond segment. Long service life. Insensitive to heat development, excessive contact pressure and excessive speeds
Optimal protection against segment loss thanks to a special sintering process
No chipped edges and absolutely clean and precise holes
