Hougen® Step Drill, HSS TiN Coated, 1/8"-1/2" Dia. x 1/32" Increments

Parabolic flute disperses chips away from the cutting edges more rapidly and increasing coolant flow. Exceptional for deep-hole drilling. Manufactured from high-speed steel. Aerospace-style 135° split point is self-centering, reducing walking. Faster penetration rates than conventional HSS heavy duty jobber drills. TiN (Titanium Nitride) adds lubricity and hardness, enhancing chip flow, finished hole quality and drill life. For drilling in low carbon steel and soft alloy steel. Made In USA. Pack Of 6. 30 Day Warranty.
