Centering drill bit Bosch 2 608 900 590 diameter 6 mm

Bosch EXPERT HEX-9 HardCeramic drill bit (Bosch 2 608 900 590) is a 6 mm centering drill designed for precise hole placement in ceramic wall tiles. Engineered for dry drilling, it copes with larger, harder tiles and offers extended life compared with standard tile bits. The bit’s geometry and hard-ceramic tip provide stability and accuracy when starting and guiding holes in demanding tile materials.

Advantages

The EXPERT HEX-9 HardCeramic bit is built for long life when drilling hard ceramics and tiles without lubricant or cooling. Its centering design ensures accurate hole placement and reduces walking at the start. The robust construction improves wear resistance and maintains cutting performance over many holes.

Suitable for

• Drilling precise holes in hard wall tiles and ceramics
• Dry drilling where coolant or water is not used
• Professional tile installation and DIY tiling tasks requiring accurate centering

How to use

Mark the drilling point on the tile and position the centering drill bit perpendicular to the surface. Start drilling at low speed to ensure the centering tip locates accurately, then increase speed as appropriate for the tile material while maintaining steady pressure. Avoid using water or coolant; the bit is designed for dry drilling. Replace the bit when cutting performance noticeably declines.

Usage recommendations

Use personal protective equipment (safety glasses and dust mask) and clamp or support tiles to prevent cracking. For best results, drill at controlled speeds and allow the bit to cool between long runs to extend service life.
