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.
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:
| DIAMOND CORE BIT DIAMETER | SPINDLE SPEED |
| ø5.0mm | 800 rpm |
| ø6.0mm | 600 rpm |
| ø7.0mm | 500 rpm |
| ø8.0mm | 500 rpm |
| Ø10.0mm | 400 rpm |
| More than Ø10.0mm (>10.0mm) | less than 400 rpm |
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.
