Abstract
A pneumatically driven impact type set of tools including a plurality of interchangeable components having, in addition to a manually gripped housing, a common pneumatically driven reciprocating piston actuator assembly, an interchangeable set of tool heads having respectively different types of work tools associated therewith, a removable hand actuated pneumatic valve and one or more extension members which may be selectively coupled between the housing and pneumatic valve. One form of the pneumatic valve includes a safety feature in the handle sub-assembly for preventing inadvertent actuation of the valve upon release of the handle.
