PROBLEM TO BE SOLVED: To provide a grinding tool which can reduce load of maintenance and cost. SOLUTION: A base section 40 on which several grinding stones 419 are arranged and a nozzle 422 for supplying grinding liquid is formed is composed of a first section 41 where the grinding stones 419 are arranged and a second section 42 which is separable from the first section 41 and the nozzle 422 is formed. Only the first section 41 where expendable grinding stones 419 are arranged is handled as an expendable item, and the second section 42 where the nozzle 422 is formed can be used without being replaced.
