The CBN ground and spiral flutes guarantee quiet running and high cutting performance. Especially the chip flow is optimized, so even long, non breaking chipswill 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
