135° Split point is self-centering for reduced thrust and easier penetration. Manufactured from high-speed steel substrate with heavy duty geometry. Black and gold (Barber pole) oxide finish for less galling. Three flats on shank for sizes above 11/64" for tighter chucking and less slippage. For superior rigidity in maintenance applications in low to medium carbon steel, alloy steel and cast iron.

Heavy-duty construction for drilling in tougher materials. Manufactured from premium high-speed steel. 135° P3 split point is self-centering for reduced thrust and easier penetration. Sizes smaller than .0625" do not have split point. Black oxide surface finish increases wear resistance and adds lubricity, improving chip flow. For drilling in stainless steel, tool steel, alloy steel and cast iron.
