These heavy-duty, impact-ready drill bits are designed for use with your impact driver. The hex-shank bits are ground from a single piece of solid steel for maximum durability. In fact, Dewalt impact-ready drill bits last up to five times longer than standard two-piece bits. The bits also feature a patented no-walk Pilot Point tip that starts quicker than a split-point bit, resulting in precise, splinter-free holes. And its patented web taper increases the bit?s rigidity to greatly decrease bit breakage.
