ABSTRACT:
A tool for abrading a workpiece to smooth the surface thereof. The tool has a shank portion and a working portion. The working portion has a smooth and non-abrading surface, with one or more depressions formed therein. Each depression includes an abrading mechanism. The abrading mechanism does not protrude above the smooth surface of the working portion of the tool. During operation, once the workpiece has been smoothed by removal of the raised areas by the abrading mechanism, the smooth surface of the tool engages the workpiece and further abrasion of the workpiece is prevented.
