Bosch 5 Piece Extra Hard Torx Screwdriver Bit Set

The Bosch 5 Piece Extra Hard Torx Screwdriver Bit Set is a set of screwdriver bits designed for universal screw-driving with screwdrivers and drill drivers. It covers five Torx sizes (T10, T15, T20, T25 and T30), so one set suits a range of fixings. Each bit is made from S2 modified steel and goes through an optimised heat treatment process to give extra-hard quality. The tapered torsion zone absorbs force and vibrations 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. This makes the set a practical choice for tradespeople and competent DIYers who use Torx screws with both manual screwdrivers and drill drivers.
