Description

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. Due to the TiN wear protective coating the surface hardness increases up to approx. 2.300 HV and the heat resistance up to 600 °C.
