Irwin (928) IWAF31PH12 IMPACT 1IN PHILLIPS No.1 – 2 PACK

IRWIN Accessories. 1″ x No.1 SAE Black Oxide Phillips Insert Impact Bits (2 Pieces) (IWAF31PH12) by IRWIN. While most screwdriving bits are simply compatible with impact drills and drivers, IRWIN Impact Performance Series fastener drive bits are engineered for maximum durability and long life with impact drivers. These bits are forged rather than milled, so they fit fasteners more precisely, which reduces stripping and increases the life of the bit itself – IRWIN’s Impact Performance Series bits have 3 times longer life than traditional bits. Manufactured with heavy-duty, cold forged, high-grade steel, they’ll withstand extremely high torque output. Plus, a black oxide finish resists corrosion and increases the life of the bit.
