Patent ID: 8579553

Claim:
A method of installing coaxial cable 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 for securing the proximal end of the drill bit to the 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 coaxial cable to the attachment mechanism on the hollow tip of the proximal end of the drill bit by inserting supported conducting wire of the coaxial cable in an aperture in the hollow tip of the drill bit and rotating connector assembly with threads on its inside circumference to threads on the outside circumference of the outside wall of the hollow tip of the drill bit, inserting the drill bit connected to the coaxial cable through the aperture, and, removing the coaxial cable from the attachment mechanism after the proximal end and attached coaxial cable pass through the aperture.
