BLUE-DUR coating for a further substantial increase in service life also when machining dry (no/less cooling). The CBN ground and spiral flutes guarantee smooth running and high cutting performance. The chip flow is optimised and removed easily as with a twist drill. Ideal for thicker sheets from 2 mm.
