A milling tool includes insert seats in which respective cutting inserts are disposed. Positioned in each seat is a wedge plate which is adjustable relative to the tool body in a direction of wedge adjustment. A cutting insert is supported on the wedge plate and secured directly to the tool body. The wedge plate is wedge shaped such that when the wedge plate is adjusted relative to both the tool body and the cutting insert, the cutting insert is displaced in a direction perpendicular to the direction of wedge adjustment.

Milling tool having an adjustable insert seat

An improved slot-drilling cutter has a tool body with plate seats at the end, which are arranged symmetrically in respect to each other. Cutting plates are arranged on the seats, whose cutting edges, as well as possibly cutting edges are set identically, i.e. which cover each other completely in the circumferential direction. Because of this, respectively two cutting edges are active for the drilling operation, as well as for the milling operation, which increases the metal cutting yield and allows the same advancement when drilling, as well as when milling. The slot-drilling cutter is free of lateral forces because of the symmetrical design, which permits a high degree of working precision in spite of large advancement moves.

Metal cutting tool with direct cutting plate arrangement

A milling tool (1) has at least one insert seat (14) which is adjustable in the axial direction. Provided for this purpose as an insert seat is a cartridge (47) which is received in a groove (41) but does not have a supporting face for the bottom face of the insert (25). The insert (25) consequently rests on a side wall (42) of the groove (41). As a result, the insert seat (14) is formed by a combination of the plane face of the tool body (2) and bearing faces (51, 52) of the cartridge (47). This achieves a particularly small installation space (close tooth spacing) and rigid mounting of the insert (25).

Milling tool with axial adjustment

A cutting bit formed as a round plate for a material removal tool has a base body, which is defined by a bottom face, a top opposite it and spaced apart from it, and a side face between them. The side face, with a chip face located on the top, defines a circular cutting edge. For securing the bit, a central opening which can receive a securing screw, for instance, is provided. To secure the cutting bit in a tool body in a manner fixed against relative rotation, a plurality of depressions, for instance, are provided on the top of the cutting bit and can be engaged by a clamping claw supported on the tool body. Circumferential forces engaging the cutting bit are diverted by way of these depressions, thus preventing torsion or twisting of the cutting bit.
