1. A coring tool for coring a coaxial cable having an axially extending cylindrical central conductor, a generally cylindrical dielectric core coaxially surrounding the central conductor, and a generally cylindrical tubular outer conductor coaxially surrounding the dielectric core, said coring tool comprising:
a tool holder; and
an axially elongated cutter bit mounted to and projecting axially outwardly from said tool holder;
wherein said cutter bit has a forward end and a coaxial cylindrical bore defined by a bore wall, with said bore opening through said forward end, said bore configured to receive an end portion of the central conductor therein, said bore having a diameter greater than the diameter of the central conductor, said cutter bit having a generally cylindrical coring portion proximate said forward end for rotatably drilling out and removing the generally cylindrical dielectric core surrounding the central conductor of the coaxial cable, said coring portion having an outside diameter approximately equal to an inside diameter of the outer conductor; and
wherein said coring portion of said cutter bit is constructed of at least first and second parts which are connected together, said first part being formed of an electrically conductive metal or alloy, and said second part being formed of a non-conductive material.
