The diamond core bit is used to drill holes in ceramic tiles, marble, grade 5 porcelain (hardest), granite, glass, and slate. The bit must be used with water at all times to prevent the diamonds from overheating, and the maximum allowable temperature is 500°C. There is no pilot drill with the diamond core bit, and a low rpm rotary drill with a planetary gearbox is required.
It is possible to use a cordless drill, but in the lowest gear setting. No hammer action is used. The diamond core bit will last up to 10 or more drilled holes in hard tiles.
