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) and Torx (T) drive types in one set, making it a practical choice for general trade and DIY fastening work.

Each bit is made from S2 Modified Steel with an optimised heat treatment process, giving extra-hard quality for dependable performance across a wide range of screw-driving jobs. The tapered torsion zone absorbs force and vibrations, helping the bit cope with torque peaks during driving.

The 1/4-inch external hex shank gives a strong connection and effective torque transmission in three-jaw chucks and 1/4" internal hex tool holders. The set includes PH1 to PH3, PZ1 to PZ3 and T10 to T40 bits, plus a QC UH.
