ABSTRACT:
A rotary tool for performing surface finishing operations such as sanding, grinding, buffing, polishing and others. The tool has a rotary spindle with a shank portion at one end of which is retained by a rotary chuck of a power source. A portion of the spindle at the opposite end has a flexible planar surface finishing member attached to it in such manner that the member lies in a common plane with the longitudinal axis of the spindle. The finishing member is preferably made of multiple flexible layers fastened together by a centrally located eyelet. The finishing member bends when rotated against a flat or curved surface to be finished and sweeps in a linear direction across the surface. This tool is especially useful for deburring holes and is self centering when inserted in a hole.
