Ruko Step Drills HSS Spiral Fluted with Split Point No. 3 101053

Ruko Step Drills HSS Spiral Fluted with Split Point No. 3

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 cone makes it easier to withdraw the tool from the material.
