A peeling plate having - an upper side and a lower side, - lateral faces that extend between the upper side and the lower side, - primary cutting edges and secondary cutting edges that are configured at the transition from the lateral faces to the upper side, wherein the peeling plate in a plan view of the upper side has the shape of a substantially regular n -gon of n-fold symmetry with respect to a symmetry axis, and n lateral edges lying between the n lateral faces, wherein a primary cutting edge and a secondary cutting edge are configured at the transition from at least one lateral face to the surface, characterized in that n is five or six, and in that active primary cutting edges and active secondary cutting edges are spaced apart from a lateral edge, said lateral edge at the transition to the upper side forming an active cutting corner to the respective active primary cutting edge and active secondary cutting edge, wherein at least one first part-face which conjointly with the upper side forms a secondary cutting edge is configured on at least one lateral face, and at least one further part-face which conjointly with the upper side forms at least part of a primary cutting edge is configured on the at least one lateral face, and wherein the first part-face conjointly with the further part-face encloses an external angle (α1) of greater than 180° and smaller than 220°, and wherein a third part-face is configured on at least one lateral face, which third part-face in relation to the further part-face is inclined by an angle (α2), wherein the further part-face and the third part-face conjointly with the upper side form the primary cutting edge. - an upper side and a lower side, - lateral faces that extend between the upper side and the lower side, - primary cutting edges and secondary cutting edges that are configured at the transition from the lateral faces to the upper side, wherein the peeling plate in a plan view of the upper side has the shape of a substantially regular n -gon of n-fold symmetry with respect to a symmetry axis, and n lateral edges lying between the n lateral faces, wherein a primary cutting edge and a secondary cutting edge are configured at the transition from at least one lateral face to the surface, characterized in that n is five or six, and in that active primary cutting edges and active secondary cutting edges are spaced apart from a lateral edge, said lateral edge at the transition to the upper side forming an active cutting corner to the respective active primary cutting edge and active secondary cutting edge, wherein at least one first part-face which conjointly with the upper side forms a secondary cutting edge is configured on at least one lateral face, and at least one further part-face which conjointly with the upper side forms at least part of a primary cutting edge is configured on the at least one lateral face, and wherein the first part-face conjointly with the further part-face encloses an external angle (α1) of greater than 180° and smaller than 220°, and wherein a third part-face is configured on at least one lateral face, which third part-face in relation to the further part-face is inclined by an angle (α2), wherein the further part-face and the third part-face conjointly with the upper side form the primary cutting edge.
