DeWalt has the first industrial drill bit specially designed to maximize the performance of your drill. DeWalt's Pilot Point drill bits are designed to solve the common problems professionals encounter when drilling with portable drills into metal and wood: walking, spinning and breaking. The patented Pilot Point tip, (sizes 1/8-inch and over), prevents the bit from walking across the workpiece, while providing a clean, round hole. The No Spin shank, (sizes 3/16-inch and over), overcomes the professional's frustration with keyless chucks, bits spinning in the chucks. And, with the patented tapered web, breaking is a thing of the past.
