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 Ø40.0mm (>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.
