HSS-G Tri-Angle Shank Step Drill for Drilling Metal

The CBN ground and spiral flutes guarantee quiet running and high cutting performance.

Especially the chip flow is optimized, so even long, non-breaking chips will be removed easily.

The optimized chip flow protects the cutting edges and reduces built-up edges and cold weld

marks. The chamfer on the base of the cone makes withdrawal of the tool from the material

simple when through hole drilling.
