PROBLEM TO BE SOLVED: To minimize waste quantity of a rotary polishing tool after completion of use. SOLUTION: A rotary polishing tool is constituted of a base plate and a polishing member 7 provided on its surface, the base plate is constituted of a central member 5 and a polishing member holding member 6 of a disc shape to be engaged with it free to connect and disconnect, and the polishing member holding member 6 is constituted of a first holding member 6a on its center and a second holding member 6b on the outside. The second holding member 6b is engaged with the first holding member 6a free to connect and disconnect. The polishing member 7 is made contact with only the surface side of the first holding member 6a. It is possible to further continue polishing work by removing the second holding member 6b on the outside of the polishing member holding member 6 from the first holding member 6a at the time when the polishing member 7 is abrased and cannot be used. It is possible to minimize waste quantity by scrapping only the abrased polishing member and the first holding member when the polishing member is abrased and cannot finally be used, and the second holding member and the central member can be repeatedly used. |
