Bosch 13 Piece M Extra Hard Screwdriver Bit Set

The Bosch 13 Piece M Extra Hard Screwdriver Bit Set is a screwdriver bit set designed for universal screw-driving with screwdrivers and drill drivers. It covers Phillips (PH), Pozidriv (PZ), Torx (T) and slotted (S) sizes, so one set suits a wide range of fixings.

Each bit is made from S2 Modified Steel and undergoes an optimised heat treatment process, giving extra-hard quality for reliable everyday performance. The tapered torsion zone absorbs force and vibrations during driving, helping the bit cope with torque peaks.

The 1/4-inch external hex shank provides a strong connection and maximum torque transmission in three-jaw chucks and ¼" internal hex tool holders. This makes the set a practical choice for tradespeople and competent DIYers who need a versatile bit set for general screw-driving.
