Core diameter: Ø3mm
Main use: Tiles
The diamond core bit is used to drill holes in:
The diamond core cuts faster, smoother and lasts longer than any other core drills.
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.
Water can be applied by
DIAMOND CORE BIT DIAMETER | SPINDLE SPEED |
Ø5,0mm | 800rpm |
Ø6,0mm | 600rpm |
Ø7,0mm | 500rpm |
Ø8,0mm | 500rpm |
Ø10,0mm | 400rpm |
More than Ø10,0mm (>10,0mm) | less than 400rpm |
IMPORTANT: The tool life will mostly depend on the proper usage and the hardness of the items drilled into. It is normal for a diamond core bit to last up to 10 or more drilled holes in hard tiles. Please remember to always use water when drilling with diamond core bits.
