A milling cutter (10), in particular a side milling cutter, is described, having a tool body (12), to which at least one cutting insert (14) is removably secured, said cutting insert being clamped by means of a movable clamping element (16) in the tool body (12) and comprising a cutting edge (18) pointing in the direction of rotation (R). The clamping element (16) clamps the cutting insert (14) from behind and is arranged on the rear side of the cutting insert (14) in the direction of rotation (R) of the milling cutter (10).

A modular rotor blade assembly includes a pair of cover plates; a base plate disposed between the pair of cover plates; a wedge disposed within a slot formed in a perimeter of the base plate; and a rotor blade attached to the wedge. One or more cover plates and/or the rotor blade with corresponding wedge are capable of being replaced without the need to replace the base plate, thereby reducing the cost or replacing the entire rotor blade assembly.

A rotatable milling cutter body has a plurality of insert seats, each communicating with a respective, rearwardly located fastener receptacle. An insert wedge occupying the insert seat and a fastener occupying the fastener receptacle are arranged along a common central fastener axis (S). The fastener has a threaded bore extending along a fastening axis (F) which is coincident with the central fastener axis (S). The fastening axis (F) defines a radial fastening direction (Rf) perpendicular thereto. Formed in a peripheral surface of the fastener is a key recess. The fastener is configured to rotate and threadingly engage a rearwardly directed threaded pin of the insert wedge, upon insertion of a key into the key recess in a direction parallel to the radial fastening direction (Rf), followed by movement of the key in a predetermined circumferential fastening direction about the corresponding central fastener axis (S).
