This High Speed Steel Heavy-Duty Jobber Length Drill features drills with right-hand direction of cut and was designed for drilling metal, wood and plastic. The drills were precision ground to tight tolerances with geometries that include a 135° split point to eliminate walking of the drills on the work-pieces and 3 flats on the shanks of drills above 11 in./64 in. for tighter chucking. This premium high speed steel drill set also has nitride black and gold treatment for increased hardness and tool longevity.
Used when drilling larger diameter holes
1/2 in. shank accommodates a larger diameter drill bit that still fits in a 1/2 in. drill chuck
118° split point eliminates walking and drills on contact along with requiring less force to push it also drills faster than a conventional pointed drill
Black and gold finish improves lubricity and allows the drill to run cooler and last longer
Right hand direction of cut
Precision ground to tight tolerances
For use in wood, carbon, alloy and cast iron steels
I purchased the CLE-LINE HSS Deming Drill Bit after attempting to use another HSS bit to drill through hardened steel. This bit was able to drill through material others could not. I would characterize this bit as a superior bit, drilling fast, within minimum tolerances, while maintaining it's sharpness, and the HD price was very competitive.
