A milling cutter tool, comprising:

• a body rotatable about an axis and having circumferentially spaced recesses in its outer periphery, each recess including leading and trailing surfaces with reference to a direction of rotation of said body, said leading and trailing surfaces converging in a radially inward direction, and said trailing surface being serrated;
• cartridges mounted in respective ones of said recesses, each cartridge including a seat adapted to support a replaceable cutting insert, and having leading and trailing surfaces, said trailing surface of said cartridge being serrated and engaging said serrated trailing surface of said recess;
• wedges disposed in respective recesses for clamping said cartridges therein, each wedge including a leading surface engaging said leading surface of said recess, and a trailing surface engaging said leading surface of said cartridge, said leading and trailing surfaces of said wedge being convergent in a radially outward direction;
