Bosch EXPERT 5 Piece HEX-9 Multi Construction Drill Bit Set

The Bosch EXPERT 5 Piece HEX-9 Multi Construction Drill Bit Set is a premium multi-material drill bit set designed for contractors and tradespeople who need reliable, accurate drilling across a wide range of substrates on the modern construction site.

Engineered for versatility, this set handles concrete, brick, granite, soft tile, wood, and metal — making it an essential addition to any professional toolkit. The advanced Bosch Centering Geometry ensures a slip-free start and stabilised action, delivering up to 5x more precise results than a Bosch CYL-3 drill bit. This makes it particularly well suited for drilling into hard or unpredictable materials like granite, where skidding is a common issue.

Each bit features a high-performance carbide tip manufactured using a fine grinding technique, allowing for razor-sharp edges that support complex, highly efficient cutting geometries. The optimised dust extraction channel works in tandem with the fluting to remove chips efficiently, keeping the drilling process clean and fast. The hex shank design provides a secure, high-torque connection in both three-jaw chucks and ¼" internal hex tool holders.
