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 In. and over), prevents the bit form walking across the workpiece, while providing a clean, round hole. The no spin shank, (Sizes 3/16 In. and over), overcomes the professionals #1 frustration with keyless chucks, bits spinning in the chucks. And, with the patented tapered web, breaking is a thing of the past. DEWALT pilot point, flat out better. | DEWALT 7/16" Gold Ferrous Oxide Pilot Point Twist Drill Bit DW1928
