Disclosed herein is a power device. The power device has a power source; timing circuitry powered by the power source for producing a current pulse output having a pulse width; a switch for triggering the current pulse output produced by the timing circuitry; an armature motor powered by the power source and in electrical communication with the timing circuitry for receiving the current pulse therefrom, the armature motor comprising: an electro-magnetic core; a first winding for carrying electric current to energize a magnetic field associated with the electro-magnetic core; a second winding for carrying current to reset the magnetic field associated with the electro-magnetic core, the first and second windings wound about the electro-magnetic core; and a swinging armature for providing movement in response to the energizing of the magnetic field about electro-magnetic core. The first winding and the second winding are bifilar wound together about the electro-magnetic core. When the switch triggers the current pulse from the timing circuitry, the armature operates at the current pulse output pulse width. The invention permits higher frequency operation and more output pressure/output to be generated with devices with variable speed motors.

A fish tape reel assembly includes a housing having a peripheral wall defining an outer wall of a cavity having a center. A housing handle is attached to the peripheral wall, and a fish tape cassette is rotatably mounted in the cavity. The cassette rotates in the cavity to wind and unwind fish tape thereon to retract or extend the tape to and from the housing in a feed direction which is perpendicular to the housing handle. A handle on the cassette pivots to lock the cassette into a locked position which prevents the cassette from rotating. A fish tape end piece is wedge shaped to create a path between surfaces requiring separation.
