Bosch 35 Piece Drill and Screwdriver Bit Set for Masonry

The Bosch 35 Piece Drill and Screwdriver Bit Set for Masonry is a combined drill bit and screwdriver bit set for universal drilling and screw-driving. It includes CYL-3 masonry drill bits for abrasive materials such as concrete and natural stone, in sizes from 3.0 mm to 8.0 mm. The cylindrical shanks suit both corded and cordless impact drills. The screwdriver bits are made from S2 Modified Steel with an optimised heat treatment process for an extra-hard finish. A tapered torsion zone absorbs force and vibration, so the bits cope with torque peaks when driving screws. The set covers PH, PZ, slotted, hex and TH profiles, plus 8, 10 and 13 mm nutsetters and double-blade bits. All screwdriver bits are colour-coded, so you can pick out the right type at a glance. The bits have a 1/4-inch external hex shank for use with screwdrivers and drill drivers. A magnetic universal holder and a universal holder with quick-change function are included. Everything is supplied in a robust storage box that shows the contents clearly and keeps the set organised for storage and transport.
