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.
IRWIN® Impact Performance Series™ socket adapters are engineered for maximum durability, performance, and long life with impact tools. They feature a ball-lock retention design for applications when quick-change is ideal. The body of the socket is forged for additional strength. They have a black oxide finish that resists corrosion and increases the life of the tool. Plus, with a 1/4" quick-change shank, they're designed to work with all types of impact and rotary drivers.
Products in IRWIN’s new Impact Performance Series line are available in multiple set configurations. Our Pro Sets, available as 6- to 47-piece sets, are in durable molded plastic cases that hold up to anything the jobsite can throw at them. Bits are held securely in place until ready for use, and can easily be removed or returned to the case with a simple two-step in/out process. Also available are 20-piece Pro-Paks™ and 16- and 34-piece automotive sets.
