Abstract
A milling cutter comprises a cutter body having two concentric annular rings. An outer ring is provided for rough milling and includes a plurality of cutting inserts equally spaced about the periphery of a cutter body. An inner finish ring comprises a ring member having a coating of abrasive material. As a result, a workpiece can be milled by a single milling cutter with the rough cutting inserts and then the abrasive material.
