30mm Diamond Core Bit

Core diameter: 30mm
Main use: Tiles

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.

  1. Tightly fasten the diamond core bit in the drill's chuck
  2. 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
  3. A notch will be made (this is normal)
  4. Gradually move the drill from 45° to 90° and continue drilling until finished
  5. 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)

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.
