Bordo 3/4" x 1/2” Reduced Shank Drill Bit - Carded

118° notched point 30° helix
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 edge
