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. Tightly fasten the diamond core bit in the drill's chuck. 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. A notch will be made (this is normal). Gradually move the drill from 45° to 90° and continue drilling until finished. 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.
