The rough grinding wheel has a stabilizing core (12) for stabilizing the rough grinding wheel, said stabilizing core (12) being associated with the at least one abrasive layer (8a, 8b) and being circumferentially adjacent to the central recess (2) and having higher strength than the at least one abrasive layer (8).
