How to use

Mark the desired drill position and use the Bosch centering drill bit with a suitable rotary drill or drill stand.

Start at low speed to establish the centre and then increase speed as appropriate for the tile and drill. Withdraw periodically to clear dust and check progress.

Usage recommendations

Use appropriate eye and hand protection, secure tiles before drilling, and test on a scrap piece if necessary to confirm speed settings and technique for your specific tile type.
