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-degree 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.

These should be in the store. (But, I was/am glad that I was able to find them through your site and get them from the store’s pick-up counter with No Shipping charge.)Great drill bits!

I had to drill about 30 holes on a 1/8″ hardened steel plate, and I thought I might need to use a few of them. It turns out that 1 is enough for the entire project. Highly recommanded
