Jobber Length Drill Bit: 13/64", 135° Split Point, TiN-Coated HSS, Parabolic Flute

These chip-clearing, high-speed steel extended-length drill bits have parabolic flutes that have wide, deep flutes that improve chip flow and heat dissipation, which means feed rates do not need to be reduced as the drills move deeper into the workpiece. High Speed Steel drill bits absorb more shock and vibration than cobalt and carbide, making them suitable for use in manual drilling machines and handheld power tools. TiN coating is a general purpose coating that protects against wear and has a ceramic coating that is hard and heat resistant. It resists impact better than TiAlN and AlTiN coatings. It has a coating oxidation temperature of 550° C and a coating hardness of 2300 HV.
