ABSTRACT:
A socket wrench powered by an electric motor which has an enclosing housing (20) with a handle (22) and a motor (30) driving a gear cluster (34) and a mating driven gear train (46) reducing the rotational speed of the motor. A geared hub (58) interfaces with the gear train and rotates a removable socket (74) at right angles to the motor. The workpiece is positioned within the socket and is driven in either direction, as selected by the switch (88) and the speed of rotation is controlled manually by the variable resistance switch (86). The wrench allows a nut to be continuously driven along an extended shaft in controlled direction and speed.
