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.

Dependent claims

A system for installing a length of cable through a wall, the system comprising in combination:

an electric drill having a drill chuck at the forward extent of the drill and a handle at the rearward extent of the drill, the drill adapted to drive the chuck in either a clockwise or anti-clockwise sense;
a tubular routing tool having a diameter, a first end, a second end and an intermediate extent therebetween, the routing tool being formed from steel and having an overall length of 10.5 inches, a series of three tangs formed about the first end of the tool, each of the tangs having a length of 0.5 inch, the series of tangs removably secured within the drill chuck of the drill, a series of eight cut teeth at the second end of the tool, each of the cut teeth having a lower base end, an upper pointed end, and a length of 0.25 inches, thus the length of the cut teeth being half the length of the tangs, the cut teeth functioning to cut a hole equal to the diameter of the tool, the tool having an inside diameter of at least 0.375 inches;
a drill bit having a length greater than the length of the tool and adapted to be secured to the drill bit along with the tool such that the drill bit extents within the inside diameter of the tool.

Dependencies are inferred from the claim text.
