Abstract

A rotary polishing tool comprises a disk-shaped polishing portion corresponding to a workpiece and a disk-shaped substrate which is positioned on the rotary center of the polishing portion for supporting the polishing portion.
The substrate is provided with a mounting hole through which a driving shaft is passed on the rotary center. The substrate is made of metal and is provided with a lot of holes, and there is provided a rubber layer which is interposed between the polishing portion and the substrate and vulcanized and bonded to the polishing portion and the substrate to fix the polishing portion and the substrate to each other.
