Coring tool for coaxial cable

A coring tool is provided for preparing the end of a coaxial cable having an inner conductor, a precoat layer adhered to the inner conductor, a dielectric material adhered to the precoat layer, and a surrounding tubular metallic outer conductor. The coring tool comprises a housing having an open end adapted for receiving the coaxial cable and a cutting tool mounted to the housing and extending coaxially toward said opening. The cutting tool includes a cylindrical coring portion having an outside diameter sized to be received within the outer conductor of the coaxial cable, an axially extending bore for receiving the inner conductor, and at least one cutting edge at the end of the coring portion which is configured for creating a tearing component on the dielectric material and precoat layer, rather than slicing the dielectric material and precoat.
