Abstract: This invention relates to a tool device. In the first embodiment, the device comprises a body defining a grip-like, handle, a tool holder joined to the body, a piston and valve assembly disposed in the body adjacent one end thereof, a conduit extending from the valve, a piston slideably disposed on the conduit, as well as means for supplying the device with a fluid under pressure. By the use of the first embodiment of the present invention, the piston is caused to reciprocate in the body thereby producing a hammer-like action. In the second embodiment of the invention, a similar tool handle is used in combination with a tool holder and motor assembly. The assembly includes means for selectively joining a tool to the assembly, and a rotary motor means having a plurality of radially disposed movable vane members, as well as means for introducing and removing a fluid from the motor.
