ABSTRACT:
A rotary milling cutter body includes a plurality of inserts positioned at a positive axial angle and a negative radial angle. Shims are disposed behind respective inserts. One of the shims is thinner than the other shims (e.g., by 20-150.mu.m) so that the insert associated with the thinner shim has a greater axial projection than the other inserts. If shims are not used, one of the inserts could be thinner than the other inserts to achieve the same effect.
