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.

A portable tool comprising in combination: a housing to be held and manipulated by a user; a motor carried by said housing; a motor driven drive member supported for rotation about a first axis relative to said housing; a shoe for mounting an abrading means, said shoe being carried adjacent said housing and supported for reciprocating movement relative thereto; first coupling means for connecting said drive member to said shoe for effecting reciprocating movement of said shoe relative to said housing in response to rotary movement of said drive member; a counterweight carried intermediate said housing and said shoe for reciprocating movement relative to said housing parallel to and in alignment with said shoe; and second coupling means separate from said first coupling means for connecting said shoe to said counterweight for effecting reciprocating movement of said counterweight relative to said housing in response to reciprocating movement of and oppositely directed relative to said shoe.
