An outer ring is provided for rough milling and includes a plurality of cutting inserts spaced about the periphery of the cutter body. Positioned radially inward of the outer ring is at least one inner finish ring. The finish ring comprises a coating of abrasive material. As a result, a workpiece can be both rough and finish milled by a single milling cutter with the rough cutting inserts and the abrasive material.
