Bosch 3 Piece 89mm Long Phillips Screwdriver Bit Set

The Bosch 3 Piece 89mm Long Phillips Screwdriver Bit Set is a universal-use screwdriver bit set with PH1, PH2 and PH3 sizes. It suits general screw-driving with screwdrivers and drill drivers. Each extra hard Phillips screwdriver bit is made from S2 Modified Steel and goes through an optimised heat treatment process. The tapered torsion zone absorbs force and vibration during screw-driving, 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. At 89mm long, the bits suit a range of everyday fixing tasks.
