An improved power operated tool holder and actuator unit (10) is provided which permits use of conventional, manually operable pivoted dual-leg tools (e.g., pliers, nippers or crimpers) and eliminates the need for specialized tools of this character. The unit (10) includes a tool holder (20) operably coupled with an actuator (18) which can be controlled by a foot switch (14). The holder (20) has upper and lower tool leg clamps (78, 82) which respectively hold the ends (178, 180) of a dual-leg tool (172). The lower leg clamp (82) is coupled via an operator (80) to a pneumatic piston and cylinder assembly (30) controlled by switch (14). In use, a charge of pressurized air delivered to the assembly (30) effects movement of a piston rod (40) which in turn moves leg clamp (82) so as to close the work performing ends (182, 184) of the tool (172).
