Abstract
A rough grinding wheel for processing material surfaces includes a wheel-shaped base body having a central recess penetrated by an axis of rotation for direct or indirect connection to a drive shaft of a tool. The rough grinding wheel has a stabilizing core stabilizing the rough grinding wheel. The stabilizing core is associated with at least one abrasive layer circumferentially adjacent to the central recess. The stabilizing core has a higher strength than the at least one abrasive layer.
