Abstract
A reciprocating abrading, polisher or buffing tool is disclosed in which a counterweight for a shoe adapted for the mounting of an abrading, polishing or buffing member is driven by the shoe for oppositely directed reciprocating movement. Pairs of guides for supporting the shoe and counterweight for reciprocating movement are mounted on a shroud having halves fixed to each other and to depend from a rim of a body of the sander or polisher, so as to permit selective rotational displacements of the shoe and counterweight relative to the body. In one form of the invention employing suction to withdraw dust from adjacent the shoe, the shroud is employed to positionally locate an L-shaped connecting duct relative to a dust discharge opening in the shoe and a dust collecting duct leading to an aspirator.
