- According to the diameter radially-adjusted CBN ground relief.
  Result: The cutting edge is always the highest point of the diameter

- Each diameter receives its own relief angle.
  Result: The cutting edge is also always the highest point.
CBN deep-ground flutes leads (unlike miled grooves) to significantly smoother and sharper cutting edges. This result is: Higher cutting performance and tool life.

- Axial relief produces by CBN grinding leads to a smooth and low-heat cut.
