Tork Craft Diamond Core Bit 32mm for Tiles

Application: The diamond core bit is used to drill holes in: • Ceramic tiles • Marble • Grade 5 porcelain (hardest) • Granite • Glass • Slate The diamond core cuts faster, smoother and lasts longer than any other core drills. How to use the diamond core bit: The diamond core drill bit must be used with water at all times when drilling. The water serves as a coolant to prevent the diamonds from overheating. The maximum allowable temperature for a diamond core bit is 500°C. There is no pilot drill with the diamond core bit. A low rpm rotary drill with a planetary gearbox is required to be used with a diamond core bit. It is possible to use a cordless drill, but in the lowest gear setting. No hammer action is used. 1. Tightly fasten the diamond core bit in the drill's chuck. 2. Keep the bit steady at a 45° angle with the starting point on the edge of the assigned area to be drilled whilst the bit is rotating. 3. A notch will be made (this is normal). Gradually move the drill from 45° to 90° and continue drilling until finished. 4. Allow the diamond core bit to cool down completely before proceeding to drill another hole. Water can be applied by: • spraying water on the surface, • using a wet sponge, • attaching a water feed device. This is necessary when drilling into a wall tile.
