ABSTRACT:
A grinding wheel is made by locating a grindstone element in a molding tool and injection-molding a supporting part so that a portion of the grindstone element is embedded in the supporting part and securely bonded thereto by the molding operation. Recesses in the embedded portion of the grindstone element ensure good torque transmission between the molded supporting part and the grindstone element.
