Bosch 5 Piece Extra Hard Torx Screwdriver Bit Set

The Bosch 5 Piece Extra Hard Torx Screwdriver Bit Set is a versatile set of 25mm Torx bits, manufactured from S2 Modified Steel and designed for everyday screw-driving with drill drivers and screwdrivers. The Extra Hard designation comes from an optimised heat treatment process applied to the S2 Modified Steel, resulting in a hardened bit capable of consistent performance across a wide range of fastening tasks. This makes the set a reliable choice for contractors, carpenters, and general tradespeople who regularly work with Torx fixings. Each bit features a tapered torsion zone that flexes under load, absorbing torque peaks, force, and vibration during screw-driving. This reduces the risk of bit breakage and helps maintain a clean drive in the fastener head. The ¼" external hex shank ensures a secure, positive connection in both three-jaw chucks and standard ¼" internal hex tool holders.
