ABSTRACT:
A milling cutter has a cutter body including one or more steps extending along the outer peripheral edge of the cutter body. Cartridges are detachably mounted on the step, each of the cartridges having a plurality of equally spaced cutting edges. Preferably, the cutter body has a radially outer step and a radially inner step close thereto, and the cartridges with roughly cutting edges are mounted on the radially outer step. Roughly cutting edges and finishing cutting edges may be attached to the outer and inner surfaces of a single cartridge. When the cartridges are mounted on the step, the cutting edges are equally spaced fully around the cutter body for successive milling operation on a workpiece.
