While most screwdriving bits are simply compatible with impact drills and drivers, IRWIN® Impact Performance Series™ fastener drive bits are engineered for impact tools. These forged bits fit fasteners precisely, so they won't strip, and they're manufactured with heavy-duty, cold-forged, high-grade steel, so they'll withstand extremely high torque output. Plus, a black oxide finish resists corrosion. With three times longer life than traditional screwdriving bits, IRWIN's Impact Performance Series screwdriving bits will stand up to the most rigorous use and unforgiving jobsite conditions imaginable. When you need tools that work as hard as you do, IRWIN delivers.
