Irwin 1840314 Impact Drive Guide Set, 14-Piece, Steel, Black Oxide

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 3X 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.
