5 Piece Cobalt Stepped Drill Bit Set with 1/2" Reduced Shank (9/16 - 1) GSCSDSET5

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. Sizes include 9/16", 5/8", 3/4", 7/8" and 1" in a wood case.
