Bosch 13 Piece M Extra Hard Screwdriver Bit Set – 2607002564

The Bosch 13 Piece M Extra Hard Screwdriver Bit Set is a versatile collection of 25mm screwdriver bits designed for universal screw-driving with both screwdrivers and drill drivers. Manufactured from S2 Modified Steel with an optimised heat treatment process, these bits achieve an extra-hard quality that delivers reliable performance across a wide range of tasks. The 1/4-inch external hex shank ensures a strong, secure connection with maximum torque transmission in three-jaw chucks and 1/4" internal hex tool holders. Each bit features a tapered torsion zone that absorbs torque peaks, force, and vibration during screw-driving — helping to protect both the bit and the fastener under demanding working conditions. The set covers the most commonly used Phillips and Pozidrive sizes, making it a practical addition to any tradesperson's kit.
