ABSTRACT:
A percussion tool includes a housing part having a frontal end provided with an opening; a tool bit guide supported in alignment with the opening; and a tool bit slidably supported in the tool bit guide and projecting from the housing part through the opening. The tool bit is arranged for a reciprocating motion parallel to the longitudinal tool bit axis and transverse excursions substantially perpendicular to the tool bit axis. A transverse guide is attached to the housing part and displaceably receives an outer seal composed of a transverse slide. The transverse slide has an aperture through which the tool bit passes. The transverse slide and the tool bit are arranged such that the transverse slide and the tool bit move as a unit during the transverse excursions of the tool bit. There is further provided an inner seal disposed in the housing part between the transverse slide and the tool bit guide externally thereof. The inner seal surrounds the tool bit and is in a resilient contacting relationship therewith.
