These high-speed steel drills are precision ground from solid stock, and tempered to a hardness of HRC 62–64 for precise results and lasting performance.

The drill size is the same as the shank size, with diameter tolerances of +0/-0.015mm. Use these drills with adjustable chuck handpieces or in a drill press.

To further prolong tool life and for even smoother cutting, we recommend using these drills with a lubricant.
