Bosch 8 Piece Sx Extra Hard Screwdriver Bit Set

The Bosch 8 Piece Sx Extra Hard Screwdriver Bit Set is a set of screwdriver bits designed for universal screw-driving with screwdrivers and drill drivers. It covers six Phillips and Pozidriv sizes, making it a practical choice when you need to work across a range of common screw types. Each bit is made from S2 Modified Steel and undergoes an optimised heat treatment process, giving extra-hard quality for dependable performance across general tasks. The tapered torsion zone absorbs force and vibrations during screw-driving, helping the bit cope with torque peaks. The 1/4-inch external hex shank locates securely in three-jaw chucks and 1/4" internal hex tool holders, supporting strong torque transmission. The set includes two each of the PH2 and PZ2 bits, the sizes most often called upon in everyday fixing work.
