* 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.
