Method and apparatus for installing a plurality of cables

A method of installing coaxial cable and at least one wire through materials comprising the steps of:

• attaching a proximal end of a substantially cylindrical drill bit to a connector on a drilling tool, the drill bit having a hollow tip at the proximal end, the hollow tip having an attachment mechanism for receiving a coaxial cable and for securing the proximal end of the drill bit to an end of the coaxial cable, the drill bit having a shaft and a distal end for cutting through materials, rotating the drill bit forming an aperture in the materials, disengaging the proximal end of the drill bit from the connector on the drilling tool, attaching the end of the coaxial cable to the attachment mechanism on the hollow tip of the proximal end of the drill bit by inserting conducting wire of the coaxial cable in an aperture in the hollow tip of the drill bit and rotating a connector assembly with threads on an inside circumference to threads on an outside circumference of an outside wall of the hollow tip of the drill bit, attaching at least one additional wire to a first aperture located in a proximal region of the cylindrical drill bit, inserting the drill bit connected to the cable and the at least one wire through the aperture in the materials, and, removing the cable from the attachment mechanism after the proximal end and attached cable and the at least one wire pass through the aperture of the materials.
