The Bosch EXPERT 5 Piece HEX-9 Multi Construction Drill Bit Set is a versatile multi-material drill bit set designed for professional tradespeople working across a wide range of substrates on site. Engineered to deliver up to 5x more precision than the Bosch CYL-3, this set is built around Bosch's advanced centering geometry, which ensures a slip-free start and stabilised action for accurate, clean holes every time. The specially designed centring tip prevents skidding even on hard, challenging surfaces such as granite, making it equally well-suited to concrete, brick, soft tile, wood, and metal. The fine-ground, high-performance carbide tip enables razor-sharp edges and complex cutting geometry, while the optimised dust extraction channel works in tandem with the fluting to clear material efficiently during drilling. The HEX-9 shank provides a secure, positive connection in both three-jaw chucks and ¼" internal hex tool holders, ensuring maximum torque transmission throughout. Ideal for contractors, builders, and multi-trade professionals who need a single reliable drill bit that performs consistently across substrates without switching bits mid-job.
