A rotary abrading tool has a dust removal accessory that accommodates for wearing of the abrading member. The tool has a portable housing having a handgrip portion and a rotatably driven shaft extending from the housing. A backing plate is mounted to an end of the shaft for rotation therewith, An abrading member mounted to the backing plate. A shroud base is stationarily mounted to the housing around the backing plate. A plurality of concentric rings of successively smaller diameters are carried by the base, each of the rings having an outer diameter that frictionally engages an inner diameter of another one of the rings. The rings are movable relative to the base from a contracted position to an extended position, defining a generally conical enclosure that surrounds the abrading member. An exhaust tube extending from the base for creating a suction within the base and the conical enclosure to collect dust particles.
