Bosch Professional HardCeramic HEX-9 Drill Bit Set 5pc 4-10mm for Tiles

Lasts up to 10x longer than standard tile 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 HardCeramic 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 HardCeramic Drill Bit drill bit is designed for drilling ceramics and can drill holes in hard tiles without lubricant or cooling. Hex shank for maximum power transfer in standard three-jaw drills and hexagonal screwdriver chucks.
