DeWalt’s new Cobalt drill bits feature a patent pending web taper design and an optimized 135-degree split point that allows them to start on contact and penetrate tough materials quickly. For faster drilling and chip ejection, the Cobalt Drill Bits also feature a unique, heavy-duty flute design, which produces faster chip ejection.
The company’s new heat treatment process also helps extend bit life and performance. The line also includes jobber and screw machine lengths.
