Most double-ended screwdriving bits require a bit holderfor use with impact tools, but IRWIN Impact Performance Series double-endedpower bits feature DoubleLok technology so both ends of the bit lock securelyinto impact drivers and quick-change chucks. In fact, they're engineered formaximum durability and long life with impact tools. These bits combine two bittips in a durable one-piece design for added convenience and extended life, andeach end of the bit has a 1/4" quick-change shank that fits directly intoan impact driver - a feature only available with IRWIN bits. The bits aredesigned with precision tip geometry so they fit fasteners more precisely,which reduces stripping and cam-out. They're manufactured with heavy-duty,cold-forged, high-grade steel to withstand high torque output, and a blackoxide finish that resists corrosion and increases the life of the bit. Plus,they also have a unique Power Groove design for use with the exclusive IRWINMagnetic Collar Attachment, which prevents fasteners from slipping andwobbling.
