Parabolic jobber length drill bit has a long reach for deep drilling applications
High-speed steel (HSS) provides hardness for wear resistance
Uncoated (bright) finish has no additional surface treatment or coating
Self-centering 135-degree notched point penetrates material without a pilot hole more easily than a conventional point, and maintains a sharp cutting edge
Wide parabolic flutes increase coolant flow and chip evacuation, and are stronger and more rigid than standard parabolic flutes for deep drilling in difficult-to-machine materials
Made in the USA
