Bosch 13 Piece M Extra Hard Screwdriver Bit Set

The Bosch 13 Piece M Extra Hard Screwdriver Bit Set is a PH and PZ screwdriver bit set designed for universal screw-driving with screwdrivers and drill drivers.

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

The 1/4-inch external hex shank gives a strong connection and good torque transmission in three-jaw chucks and ¼" internal hex tool holders. The set covers Phillips (PH1, PH2, PH3) and Pozidriv (PZ1, PZ2, PZ3) sizes, so it suits general fixing work for tradespeople and competent DIYers alike.
