ABSTRACT:
The present invention relates to a system for installing a length of cable through a wall. Thus, the system of the present invention can be used to route a television, telephone or computer cable through an existing wall. The system employs an electric drill and associated drill bit. Over the drill bit a routing tool is adapted to be fitted into and secured to the drill chuck of the drill. In use, both the drill bit and tool are secured to the drill. In the preferred embodiment, the drill bit is long enough to extend beyond the end of the tool. Next, the drill is used to cut a hole into a wall. Once through the wall the drill bit can be removed from the tool and the tool can be left within the wall. Any type of cable can now be positioned through the tool within the wall. Lastly, the routing tool can be removed from the other side of the wall and used again elsewhere.
