How to use

Mark the drilling point and secure the tile or workpiece. Fit the Bosch EXPERT HEX-9 HardCeramic 5 mm centering drill into a compatible chuck or HEX-9 holder. Start drilling at low speed to establish a centered hole, then increase speed as needed while applying steady, moderate pressure. No lubricant or cooling is required for hard ceramic tiles; pause occasionally to clear debris and check progress.

Recommendations

Use appropriate eye protection and dust extraction when dry drilling. For particularly brittle tiles, perform a test drill on a spare piece and adjust speed and pressure to avoid chipping. Replace the bit when cutting performance or hole quality deteriorates.
