ABSTRACT:
A wall fitting for penetrating interior walls of a residential/commercial building which provides a through passage for running lengths of wiring such as for stereo, television, computer and other communication systems. The wall fitting includes a rigid, elongate tubular shaft having a head end and a tip end with a through passage extending the length of the shaft. The tip end is specifically adapted for penetrating sheetrock wall board. The shaft tip end is specially adapted for cutting through the wall board and has a plurality of transverse grooves located inwardly at the tip end for breakoff. A bezel fits over the stub end of the shaft to provide a finished appearance. A first alternative embodiment uses a handle specifically adapted to drive the wall fitting tubular shaft through the wall and with an easily removable and changeable penetrating tip end. A second alternative and preferred embodiment is similar, but has a metal inner shaft removable from the tubular shaft. The inner shaft provides rigidity for driving the tool through a wall.
