The ground CBN helical flutes ensure quiet machining and high cutting performance. Chip flow is optimized, ensuring even long, continuous chips are easily removed. This optimized chip flow protects the cutting edges and reduces the formation of built-up edges and cold weld marks. The taper facilitates tool removal from the material.
