Abstract

The cutter has a basic member (12) with central fixing hole (13) and cutter blades (14) adjoining the basic member radially relative to the fixing hole. The cutter blades are made from an intimately bonded compound layer of hard metal and soft metal (19). The basic member and blades can be made in one piece. The softer metal facing the ground wears faster than the harder layer to produce a wear pattern corresponding to a resharpening of the cutting edge. The two longitudinal edges of the cutter blade form the cutting edges adjoining one another at the free end (18) of the blade. The free end is preferably the shape of an isosceles triangle in plan view.
