Bosch 3 Piece Extra Hard Phillips Screwdriver Bit Set

The Bosch 3 Piece Extra Hard Phillips Screwdriver Bit Set includes PH1, PH2 and PH3 bits for universal screw-driving with screwdrivers and drill drivers. Each bit is made from S2 Modified Steel and undergoes an optimised heat treatment process, giving extra-hard quality for dependable performance across general screw-driving tasks. 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 1/4" internal hex tool holders. With all three common Phillips sizes in one set, it suits tradespeople and competent DIYers who need a practical choice of bits for everyday fastening work.
