The Bosch PRO 8 Piece Impact Control Phillips PH2 Screwdriver Bit Set delivers heavy-duty performance for tradespeople who demand reliability from their screwdriver bits. Rated up to 50x more robust than the Bosch Extra Hard bit, these PH2 bits are built to withstand the demands of professional installation work. Manufactured from heat-treated modified steel, the bits offer outstanding strength and resistance to high torque. An extended torsion zone absorbs torque stress at the tip, preventing breakage during high-demand screwdriving applications — making them well suited for use with impact drivers and drill drivers. Colour-coded rings make it easy to identify the head type at a glance, while laser markings allow for quick size identification on busy job sites. The 1/4" hex shank is impact rated, ensuring compatibility with standard impact drivers and drill drivers used across the trade.
