A portable abrading or polishing tool including a body structure containing an air motor which drives a head carrying an abrading or polishing element to abrade or polish a work surface. The motor has a housing containing a chamber within which a rotor turns, with an essentially vertical shaft of the motor projecting downwardly through a bottom wall of the housing and operatively connected to the head to drive it. A wear plate is located vertically between the rotor and the bottom wall of the housing and is formed of a material harder than the rotor or housing, and contains an opening through which the shaft projects downwardly in closely fitting but non-contacting relation to minimize downward escape of air from the chamber along the shaft and protect a bearing carried by the bottom wall of the housing against loss of lubricant by the pressure of escaping air.
