Bosch Hex Extra Hard Screwdriver Bit

This Bosch Hex Extra Hard Screwdriver Bit is sized at Hex 3mm and measures 25mm in length, supplied in a pack of 3. The 3mm hex size is a highly versatile profile suitable for a wide array of everyday fastening tasks, while the 25mm length is the go-to choice for standard-depth applications and general-purpose screw-driving. Built from S2 Modified Steel with an optimised heat treatment process, the bit reaches an extra-hard quality that resists wear even under sustained use. The tapered torsion zone works to absorb force and vibrations during driving, coping comfortably with torque peaks to protect the bit and the screw head. The 1/4" external hex shank locks securely into three-jaw chucks and ¼" internal hex tool holders, ensuring broad compatibility with screwdrivers and drill drivers.
