Place the diamond crown or holesaw into the correct size hole of the drill plate and press the drill bit up against the porcelain ceramic tile or other hard material lik granite or marble.

If you have slightly wet the drill bit first by dipping it into water then this helps to cool it.

Slowly drill for between five and ten seconds but no more. You do not want to build heat into the holesaw.
