The diamond core cuts faster, smoother and lasts longer than any other core
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
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
Please have a look at the video in the tabs above
showing how to use the diamond core bit.
An indication of the correct spindle speed:

More than Ø40.0mm (>10.0mm)
less than 400 rpm
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.
