1 . CBN ground flute
CBN deep-ground flutes have better and sharper cutting edges - without burrs - unlike conventional milled flutes.This guarantees a superior cutting edge and considerably longer tool life. The CBN ground countersinkers ensure an excellent chip flow,chatter free working, scratch-free surface and have ideal centring features.
2 . Radially adjusted relief produced by CBN grinding
Because the radially-adjusted relief produced by CBN grinding relates directly to its diameter, the cutting edge is always the highest point of the diameter.
3 . Axial relief produced by CBN grinding
The axial relief produced by CBN grinding guarantees a smooth low-heat cut.
4 . CBN ground relief angle
Each diameter has its own relief angle. Consequently the cutting edge is always the highest point, too.
