Description
118° notched point 30° helix reduced shank drill. BRIGHT/BLACK FINISH These drills are ground and then a black finish is achieved by steam tempering, a thermal process resulting in a porous tool coating. This surface aids chip flow and heat dissipation. The drill is then ground a second time to achieve a bright finish on the shank and cutting edges. 2651-9/16: 9/16" 1/2" Reduced Shank Drill 2651-5/8: 5/8" 1/2" Reduced Shank Drill 2651-11/16: 11/16" 1/2" Reduced Shank Drill 2651-3/4: 3/4" 1/2" Reduced Shank Drill 2651-13/16: 13/16" 1/2" Reduced Shank Drill 2651-7/8: 7/8" 1/2" Reduced Shank Drill 2651-15/16: 15/16" 1/2" Reduced Shank Drill 2651-1: 1" 1/2" Reduced Shank Drill
