The Bosch EXPERT 5 Piece HEX-9 Multi Construction Drill Bit Set is a versatile multi-material drill bit set designed for tradespeople who need to work across a wide range of substrates on the same job. Built around Bosch's advanced centring geometry, each bit in this set delivers a slip-free start and stabilised drilling action — making it up to 5x more precise than a Bosch CYL-3 drill bit. The specially engineered centring tip ensures accurate hole placement first time, whether you're working in granite, concrete, brick, soft tile, wood, or metal. The high-performance carbide tips are produced using a fine grinding manufacturing technique, allowing razor-sharp cutting edges that maintain performance over hundreds of holes. The optimised fluting and dust extraction channel work together to clear chips efficiently, keeping the drilling process fast and clean. The ¼" HEX-9 hex shank provides a secure, positive connection in both three-jaw chucks and quick-release hex tool holders, making these bits compatible with a wide range of cordless drills. Ideal for contractors, electricians, and fixers who regularly switch between materials and need one reliable bit that handles them all.
