High Performance TiN Coated Screw Machine Length Drill Set

Style 159HPT

High performance, HSS screw machine drills with titanium nitride (TiN) coating to allow up to 20% increase in cutting speed to maximize high speed drilling efficiency. HP flute geometry, with large flute area and high helix angle, accelerates chip ejection and increases coolant flow to workpiece. Self-centering, 130° helical point reduces drilling time, increases cutting efficiency and improves hole accuracy.
