ABSTRACT:
A combination between a grinding ring and a grinding wheel is disclosed, wherein the grinding ring has a centrally defined hole, a tubular extension extending from a periphery defining the hole, an annular extension extending from an outer periphery of the tubular extension, a skirt formed adjacent to the annular extension, teeth formed by pressing at a joint between the annular extension and the skirt and barbs each formed on a free end of the teeth. The grinding wheel is made of cloth so that the teeth together with the bars are able to extend into the grinding wheel when the skirt is pressed and engagement between the grinding ring and the grinding wheel is enhanced by applying an adhesive.
