- Built for maximum durability and long life with impact drivers
- Forged bit* (vs. milled) for superior fitment, which reduces stripping and increases life of bit 3X**
- Black oxide finish resists corrosion and increases life of bit
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 three times longer life** than traditional insert 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.
