A portable abrading tool including a body which is adapted to be held by a user and which carries a motor, a head adapted to carry a sheet of sandpaper or other element for abrading a work surface, a drive connection for transmitting power from the motor to the head to power actuate the head relative to the body, preferably orbitally, and a flexible boot or other structure extending essentially about the drive connection and enclosing a space at the back of the head. The tool preferably contains suction passages which direct a vacuum induced flow of air and particles abraded from the work surface from a location near the work surface to a dust collection bag or discharge location without flow of the abraded particles through the mentioned enclosed space at the back of the head. The passages also direct a vacuum induced flow of air free of abraded particles from that enclosed space. The tubular flexible structure which extends about the enclosed space carries projections adapted to interfit with the coacting portions of the tool body and head to locate these elements in predetermined relative positions upon assembly of the tool.
