To provide a deburring polishing grinding wheel for a vibrational tool capable of uniformly and efficiently carrying out deburring of a parting line deep in a hole, etc., and deburring of a cross hole in metal working and capable of uniformaly and efficiently polishing and removing only a part left in a risen state at the time of deburring even when it is left in this state and a deburring polishing method.

The deburring polishing grinding wheel for the vibrational tool constituted as a rod body by hardening inorganic long fiber with thermosetting resin by paralleling it constitutes its characteristic feature of making a peripheral surface in the fiber length direction of the inorganic long fiber a deburring polishing surface.
