The Bosch 35 Piece Drill and Screwdriver Bit Set for Masonry is a comprehensive accessory kit designed for professional drilling and screw-driving applications across a wide range of materials and fastener types. The screwdriver bits are manufactured from S2 Modified Steel with an optimised heat treatment process, delivering extra-hard quality suited to demanding trade use. A tapered torsion zone absorbs torque peaks and vibrations during screw-driving, helping to protect both the bit and the fastener head. All bits are colour-coded for fast identification, keeping work efficient on site. The set also includes CYL-3 masonry drill bits engineered for lasting performance on abrasive materials such as concrete and natural stone. The screwdriver bits feature a 1/4-inch external hex shank, compatible with standard screwdrivers and drill drivers, while the masonry drill bits use a cylindrical shank system suitable for corded or cordless rotary drills. The entire set is housed in a robust storage case with a clear layout for easy access, safe transport, and organised storage on site.
