Bosch 12 Piece Extra Hard Screwdriver Bit Set – 704304

The Bosch 12 Piece Extra Hard Screwdriver Bit Set is a versatile collection of 25mm bits designed for universal screw-driving with drill drivers and screwdrivers across a wide range of fastener types. Each bit is manufactured from S2 Modified Steel with an optimised heat treatment process, resulting in extra-hard performance that holds up under demanding conditions. This construction ensures the bits maintain their profile under repeated use, reducing the risk of cam-out and premature wear. The tapered torsion zone is a key design feature, absorbing torque peaks, force, and vibrations during screw-driving to protect both the bit and the fastener head. The ¼" external hex shank provides a secure, reliable connection in both three-jaw chucks and ¼" internal hex tool holders. With 12 bits covering Phillips, Pozidrive, Torx, slotted, and hex profiles, this set is well suited to general construction, joinery, furniture assembly, and electrical first-fix work where a variety of fixings are encountered.
