Milwaukee? SHOCKWAVE Impact Duty? driver bit sets are engineered for extreme durability and up to 10X life. Made from proprietary steel and heat-treated to control hardness, the SHOCKWAVE Impact Duty? insert and driver bits feature an innovatively designed geometric shock absorption zone to extend life. The forged tip allows for a secure grip and maximum contact eliminating stripping or slipping.
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.
