A hand-held powered wrench includes a primary handle and a secondary handle. A motor is mounted on a primary handle. The secondary handle provides a second hand grip position which is significantly displaced from the primary handle axis, and includes a motor control for starting and stopping the motor. By having the significant displacement of the motor controlling second hand grip position, the operator naturally chooses a better stance and naturally dissociates the motor control hand from the torque sustaining hand in operation of the power wrench. The hand-held powered wrench can be used such as for safely exercising fire hydrant valves.

1. A hand-held powered wrench, comprising: a motor for providing rotational torque about an axis of rotation to a coupling head;a primary handle supporting the motor in a stationary position relative to the primary handle, the primary handle extending to a primary hand grip position at least 18 inch
1. A hand-held powered wrench, comprising: a motor for providing rotational torque about an axis of rotation to a coupling head;a primary handle supporting the motor in a stationary position relative to the primary handle, the primary handle extending to a primary hand grip position at least 18 inches from the axis of rotation to withstand peak torque delivered by the motor, the primary hand grip position defining a primary handle axis which substantially intersects the axis of rotation at a right angle;a secondary handle mounted off the primary handle and providing a second hand grip position, the second hand grip position being significantly displaced from the primary handle axis in one or both of angle and position; anda motor control supported on the secondary handle so as to be accessible by a hand in the second hand grip position. 2. The hand-held powered wrench of claim 1, wherein the coupling head is a socket head sized for turning a fire hydrant valve. 3. The hand-held powered wrench of claim 1, wherein the second hand grip position defines a second hand axis which is at an angle of at least 30° relative to the primary handle axis, and wherein the second hand grip position is at least 4 inches from the axis of rotation. 4. The hand-held powered wrench of claim 3, wherein the second hand grip position defines a second hand axis which is substantially orthogonal relative to the primary handle axis. 5. The hand-held powered wrench of claim 4, wherein, when the axis of rotation extends substantially vertically, the primary handle axis and the second hand axis both extend substantially horizontally. 6. The hand-held powered wrench of claim 1, wherein the entirety of the second hand grip position is at least four inches away from the primary handle axis. 7. The hand-held powered wrench of claim 1, wherein, with a vertically oriented axis of rotation, the motor is mounted vertically over the primary handle. 8. The hand-held powered wrench of claim 1, wherein the motor is a variable speed motor, wherein the second hand grip position defines a second hand axis, and wherein the motor control is a grip rotatable about the second hand axis. 9. The hand-held powered wrench of claim 1, wherein the primary handle is a solid aluminum bar. 10. The hand-held powered wrench of claim 1, further comprising a gear reduction unit between the motor and the coupling head, and such that motor and the gear reduction unit of the hand-held powered wrench can deliver at least 50 ft-lbs of torque. 11. The hand-held powered wrench of claim 1, wherein the motor is positioned relative to the primary hand grip position and the second hand grip position such that, with hand-held powered wrench being held at the primary hand grip position and the second hand grip position with the axis of rotation extending vertically, the weight of the motor is substantially displaced from both the primary hand grip position and the second hand grip position and bourn by the coupling head. 12. The hand-held powered wrench of claim 11, wherein the motor is a hand-held drill disposed substantially parallel to and over the primary handle, with the output of the hand-held drill being coupled through a right angle drive so the axis of rotation extends vertically. 13. A handle arrangement for a hand-held powered wrench, comprising: a primary handle having a detachable connection adapted to support a motor in a stationary position relative to the primary handle, the primary handle extending to a primary hand grip position, the primary hand grip position defining a primary handle axis;a gear reduction unit supported by the primary unit for connection with the detachable motor, an output drive shaft of the gear reduction unit defining an axis of rotation substantially intersecting the primary handle axis at a right angle, with the axis of rotation positioned at least 18 inches from the primary hand grip position;a secondary handle mounted off the primary handle and providing a second hand grip position, the second hand grip position being significantly displaced from the primary handle axis in one or both of angle and position; anda motor control supported on the secondary handle so as to be accessible by a hand in the second hand grip position. 14. The handle arrangement of claim 13, wherein the detachable connection is a pillar having a male threaded end to be received in a female threaded hole on the detachable motor.
