THIS SET HAS 4 DOUBLE ENDED BITS AND 1 BIT HOLDER 2 - PH1, 4 - PH2, AND 2 - PH3 ENDS (SIZES) 3 PHILLIPS SIZES

Most double-ended screwdriving bits require a bit holder for use with impact tools, but IRWIN Impact Performance Series double-ended power bits feature DoubleLok technology so both ends of the bit lock securely into impact drivers and quick-change chucks. In fact, they're engineered for maximum durability and long life with impact tools. These bits combine two bit tips in a durable one-piece design for added convenience and extended life, and each end of the bit has a 1/4" quick-change shank that fits directly into an impact driver - a feature only available with IRWIN bits. The bits are designed 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 black oxide 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 IRWIN Magnetic Collar Attachment, which prevents fasteners from slipping and wobbling.

The Irwin Impact bits are compatible with air drills and regular drills, making them a versatile addition to your tool collection. With its model name and brand, you can trust the quality of these bits. Whether you're a professional or a DIY enthusiast, this set is perfect for drilling through tough materials.
