Bosch 19 Piece L Extra Hard Screwdriver Bit Set

The Bosch 19 Piece L Extra Hard Screwdriver Bit Set is a screwdriver bit set designed for universal screw-driving with screwdrivers and drill drivers. It covers PH, PZ and T drive sizes, so it suits a wide range of everyday fixing jobs. Each bit is made from S2 Modified Steel with 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. The 1/4-inch external hex shank gives a strong connection and maximum torque transmission in three-jaw chucks and ¼" internal hex tool holders. The set includes Phillips, Pozidriv and Torx bits, with multiples of the commonly used PH2 and PZ2 sizes.
