2651-S2 9/16-1" 8 Pce 1/2" Reduced Shank Drill Set Reduced shank HSS twist drill set. 118° notched point with 30° helix. Notched point is a variation on the standard chisel point, providing faster starting and reduced drill wander. 118° point angles are ideal for use in materials such as mild steel and cast iron. The 118° point creates easily controlled chips which are wide and thin. Bordo reduced shank HSS 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.
