BIT DRILL PVB COBALT SET 17PC

Made of M35 steel, 5 percent cobalt, with extra thick drill core for rigidity and strength. Used in applications such as stainless steel and space age alloys. All sizes 3/16" and larger have 3 flats on the shank for a better grip on the drill bit. The 135 degree split point eliminates the need for a center punch and keeps the drill from skating on hard materials. Includes (1) one each: 5/64, 3/32, 7/64, 9/64, 5/32, 11/64, 3/16, 13/64, 7/32, 15/64, 1/4, 5/16, 3/8" and (2) two each: 1/16", 1/8", plastic case with rubberized grip panels.
