Bosch Expert HEX-9 HardCeramic Tile Drill Bit 7 mm x 90 mm

The Bosch Expert HEX-9 HardCeramic tile drill bit delivers precise, clean holes in soft and hard tiles, ceramic, and porcelain. Its tungsten carbide tip and centering point ensure accurate starts without wandering, while the U-flute design efficiently removes dust for faster drilling and longer bit life. The hexagonal shank fits standard 1/4" quick-change chucks, making it ideal for cordless drills and impact drivers. Use dry or wet—wet drilling is recommended for hard materials to reduce heat and extend service life.

Advantages

Ground tungsten carbide tip provides exceptional wear resistance and durability, even in abrasive hard tiles. The centering tip prevents skidding on smooth glazed surfaces, ensuring the hole starts exactly where intended. The U-flute geometry rapidly evacuates debris, reducing clogging and heat buildup. The 1/4" hex shank allows fast bit changes and secure grip in impact drivers without slippage. Suitable for both dry and wet drilling, giving flexibility on the job site.

Recommendations

For best results on hard porcelain tiles, use water as a coolant and start at low speed with light pressure. Allow the bit to do the work; do not force it. For impact drivers, switch off hammer mode to avoid tile breakage. Replace the bit when cutting speed noticeably decreases.
