PROBLEM TO BE SOLVED: To provide an inner diameter grinding tool which is simple in the structure of a diameter expanding mechanism and continuously connectable with one another in a plurality of pieces. SOLUTION: The inner diameter grinding tool includes a holder 1 rotated by a spindle, an annular grinder 2 integrally rotating with the holder and capable of radially enlarging and contracting, and an expander 3 axially moving thereby radially enlarging and contracting the annular grinder. The annular grinder 2 and the holder 1 are engaged with each other to be retained. The annular grinder 2 and the expander 3 are fixed by a stopper member such as a screw 14 coupled with the expander via a part of a slit 8 formed at the annular grinder.
