The Bosch EXPERT 3 Piece HEX-9 Multi Construction Drill Bit Set is a professional multi-material drilling solution designed for tradespeople who work across a variety of substrates on the modern construction site. This versatile set includes three drill bits sized 5mm, 6mm, and 8mm, each engineered to tackle a wide range of materials including concrete, brick, granite, soft tile, wood, and metal — all from a single bit. Up to 5x more precise than the Bosch CYL-3, the EXPERT Multi Construction Drill Bit eliminates the need to stop and change bits between tasks, saving time and improving on-site efficiency. Each bit features Bosch's specialised centring geometry, which provides a slip-free start and stabilised drilling action for accurate, clean holes every time. The optimised dust extraction channel works in conjunction with the fluting to remove chips efficiently, maintaining drilling speed and reducing material build-up. The high-performance carbide tip is manufactured using a fine grinding process, enabling razor-sharp edges capable of penetrating even the hardest materials with precision. The HEX-9 hex shank design ensures a secure, rattle-free connection with maximum torque transmission, compatible with both three-jaw chucks and ¼" internal hex tool holders — making this set ideal for contractors, electricians, plumbers, and carpenters who need one reliable bit for multiple materials.
