DIAMOND CORE BIT 25MM FOR TILES

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.

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). Gradually move the drill from 45° to 90° and continue drilling until finished.
4. 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.

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.
