Bosch 13 Piece M Extra Hard Screwdriver Bit Set

Description

The Bosch 13 Piece M Extra Hard Screwdriver Bit Set is a versatile collection of 25mm screwdriver bits designed for universal use across a wide range of screw-driving applications. Each bit in the set is manufactured from S2 Modified Steel and subjected to an optimised heat treatment process, resulting in extra-hard construction that delivers reliable performance across all common tasks. This combination of material quality and precision engineering ensures consistent results whether used in a screwdriver or drill driver. A tapered torsion zone is built into every bit to manage torque peaks effectively, absorbing force and vibrations during screw-driving to reduce the risk of bit damage or cam-out. The 1/4-inch external hex shank provides a secure, stable connection with maximum torque transmission in both three-jaw chucks and 1/4″ internal hex tool holders. The set covers an impressive range of drive types, making it suitable for carpenters, electricians, plumbers, and general contractors working across mixed screw types on site or in the workshop.
