The grinding wheel has grinding plates that form a triangle with an outer corner (2), an inner corner and a rear corner (4) in a basic form. The grinding plates are arranged in uniform angular distances on an edge region of a supporting disc under formation of a grinding plates-packet (13) such that the outer corner limits a part of an outer edge (14) of the packet, and the rear corner runs leadingly from an inner edge (19) to the outer edge of the packet with respect to a rotary direction (16), where the grinding plates-material is concentrated in a radial outer region of the packet. |
