Abstract:
A milling cutter (10) comprises a cutter body (12) having at least two operational annular rings (13, 14). An outer ring (13) 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 (13) is at least one ring (14) comprises a coating of abrasive material. As a result, a workpiece can be both tough and finish milled by a single milling cutter (10) with the rough cutting inserts (18) and the abrasive material.
