- Always use SDS bits with a special SDS power drill.
- When drilling very thick holes, it is advised to start with thinner drill bits and to work your way up to the thick-sized hole you require.
- Frequently withdraw to remove the dust.
- The stop-start drilling action prevents the bit from overheating.
- When drilling multiple holes, make sure you lubricate the drill or give it a chance to cool down.
