Bosch BOR Hex HARDCERAMIC 7X90MM

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 their benchmark drill bit for tiles.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.
