NOTE: Solid Carbide Drills from WIDIA in short and regular lengths conform to DIN 6537.

High-performance solid carbide drills with tolerances of m7 create holes with
tolerances of H9. H8 can be achieved in very good conditions. The drill should
be used for holes in H8, and in favourable conditions, H7 can be achieved.
Solid carbide drills with H7 create holes in K9–K11. Other drilling tolerances
require special solid carbide drill versions.
