HSS-G Spiral Flute Step Drill for Drilling Metal

HSS-G Step Drill Bit Rotary Step Drill Bit Hex Shank Brass Steel Rail Stainless Steel

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.
