1-3/8" Cobalt Stepped Drill Bit with 1/2" Reduced Shank GSCSD1-3/8

Stepped Point Cobalt Drill Bits start easier, drill faster, last longer, and run cooler than standard bits. They can enlarge existing holes or create new, smoother holes in a wide range of materials including acrylics, steel, metal, brass, and other hard metals. Each bit features a 135-degree split point tip and a 3-flat shank to prevent spinning. The reduced shank design increases the size capacity of portable drill chucks, and the common flute and overall length minimize adjustment during tool changes. Specifications: 3" flute length, 6" overall length, 1/2" shank.
