Abstract: An abrasive tool includes in combination a tubular sleeve of exteriorly coated abrasive which has an axial length and an inside diameter. A drive arbor for the sleeve includes a mandrel adapted to be rotated by a power tool and the like. An elastomeric generally cylindrical arbor is mounted on one end of the mandrel and has an outer and inner axial end. The arbor includes a radially projecting stop flange at its inner end and has a tapered configuration between the stop flange and its outer end to receive the abrasive tubular section, but which creates an interference fit as the tubular section is telescoped on the arbor until one axial end of the tubular section engages the stop flange. The arbor body is provided with non-radial slots which make the body more pliable in a static condition, but which improve the grip of the arbor on the sleeve at speed. The slots also improve heat dissipation.
