Circle Ring
A ring is a circular pocket with a circular island in the center. A ring is
determined by its center point, outside radius (radius of the pocket)
and inside radius (radius of the island).
The direction of the cut on the inside radius will determine whether
you are climb cutting or conventional cutting. MILLPWR
G2 will reverse
the tool direction on the outside radius so that the cutting direction
stays the same.
