Bosch 2608900593 EXPERT HEX-9 HardCeramic Drill Bit 10 x 90 mm

Lasts up to 10x longer than a Bosch CYL-9 Soft Ceramic Drill Bit - As wall tiles have become larger and harder, drilling holes in them has become very demanding on a tile drill bit
That’s why Bosch has developed the EXPERT Hard Ceramic Drill Bit, which is capable of dry-drilling hard ceramics and lasts far longer than our benchmark drill bit for tiles
This specialist hard ceramic bit uses Bosch’s Carbide Technology – the hardest of metals – and combines it with an advanced multi-faceted tip design that shares the workload over multiple asymmetric faces
This complex drill bit tip, achievable through fine grinding manufacturing technique, also enables a precise start without skidding and scratching
The Bosch EXPERT HEX-9 Hard Ceramic Drill Bit is designed for drilling ceramics and can drill holes in hard tiles without lubricant or cooling
Hex shank for a strong connection and maximum torque transmission in three-jaw chucks and ¼" internal hex tool holders
