A handheld power tool for making wire ties about elongate members of the type encountered in reinforced concrete construction. The tool is comprised of a body which encompasses the machinery, above electrical logic circuitry to control the component moters, switches, and other components. Midway in the housing the device feeds wire through feed rollers and through a wire guide at the bottom of the housing which directs the wire about the members that are to be tied together. The wire continues to be fed through a circular turet to which are mounted two side-by-side clamping jaws-one which will clamp the "dead" end of the wire while the feed wheels reverse their direction to take slack out of the wire and initially tighten it about the bars. The feed wheel assembly then transiates to a position that aligns the "live" end of the wire being fed between the second (side-by-side) jaw where it is clamped and cut. The turret and attached jaws then rotate (after the feed wheel assembly is moved out of the way), which accomplishes the desired task of making a wire tie about the concrete reinforcing bars. The components then return to their beginning positions and another cycle of operation is ready to begin.
