Abstract: A tool for finishing an outside diameter surface of a cylindrical workpiece. The tool includes a rotatable substantially cylindrical member having an inner work-engaging surface adapted for finishing the O.D. surface of the cylindrical workpiece. The inner work-engaging surface includes abrasive particles thereon and defines a bore to receive the workpiece. The substantially cylindrical member includes at least one longitudinal split permitting radial expansion and contraction of at least part of the cylindrical portion for workpiece O.D. finish adjustment. The tool includes a rotable shaft, a plurality of spring loaded work-engaging elements adapted for finishing the O.D. surface of the workpiece. The work engaging elements have abrasive inserts. The plateaued O.D. surface has peaks that are 3-10 times smaller than the valleys.
