Bosch 8 Piece Sx Extra Hard Screwdriver Bit Set

The Bosch 8 Piece Sx Extra Hard Screwdriver Bit Set is a versatile collection of Phillips and Pozi bits designed for everyday screw-driving tasks across a wide range of applications. Manufactured from S2 Modified Steel with an optimised heat treatment process, each bit delivers extra-hard performance that holds up well under sustained use. This makes the set a reliable choice for contractors, joiners, and general tradespeople who need consistent results from their screwdriver bits. The tapered torsion zone is a key design feature, absorbing torque peaks and vibrations during screw-driving to reduce the risk of tip damage and cam-out. Combined with a ¼" hex shank, the bits offer a secure fit and maximum torque transmission in both three-jaw chucks and ¼" internal hex tool holders — compatible with most cordless drill drivers and screwdrivers. The set covers the most commonly used Phillips and Pozi sizes, including duplicates of the most frequently reached-for PH2 and PZ2 bits, making it a practical everyday set for the toolbox or site bag.
