Bosch Hex Extra Hard Screwdriver Bit

This Bosch Hex Extra Hard Screwdriver Bit is sized at Hex 4mm and measures 25mm in length, supplied in a pack of 3. The 4mm hex size handles a broad range of medium fastening tasks with confidence, and the 25mm length is ideal for standard screw-driving work where a compact, manageable bit is preferred.

Crafted from S2 Modified Steel and treated through an optimised heat treatment process, the bit delivers extra-hard quality that holds its edge over time. The tapered torsion zone absorbs the force and vibrations generated during screw-driving, managing torque peaks effectively to reduce bit wear and protect fastener heads.

The 1/4" external hex shank provides a dependable connection in three-jaw chucks and ¼" internal hex tool holders, making it a versatile fit for screwdrivers and drill drivers.
