ABSTRACT:
A portable abrading or polishing tool including a body containing a cylinder chamber, a piston reciprocable within the cylinder chamber, a shoe which is reciprocated relative to the body by the piston but oppositely from the piston, and at least one counterweight which is located laterally adjacent the piston and is reciprocated oppositely from the piston to reduce vibration of the tool. There may be two at opposite sides of the piston; and a third counter weight such counterweight which is located near the shoe and reciprocated oppositely from the shoe. The tool may include bearing elements interposed between the body of the tool and the shoe and containing openings communicating with passages formed in a pad carried by the shoe to conduct a flow of air or another fluid to or from those passages.
