Abstract
Abstract Apparatus and method for preparing end of coaxial cable having foamed TFE primary insulation comprises steps of engaging first blades to make a first cut completely through the outer insulation and braid, then withdrawing the blades before making a second cut which penetrates only the outer insulation, then pulling the cable against the second blades to remove slugs of outer insulation and braid as an unit. Braid is subsequently flared by rotating a tool against the exposed braid, and primary insulation is axially compressed to expose the signal conductor.
