Abstract
A cutting tool that can be used to form a stepped cable end prior to the attachment of an electrical connector to a coaxial cable. The cutting tool has a blade assembly supported inside a housing on a pair of cams. A coaxial cable is inserted into the cutting tool and the housing is rotated about the cable to push the blade assembly along spiral tracks in the cams. According to one embodiment of the invention, the blade assembly has three blades, each blade sized and positioned to make a cut of the corresponding appropriate depth in the coaxial cable thereby forming the desired stepped cable end. Cutting tools of the invention may be adapted for preparation of large-diameter (e.g., over 1 inch) coaxial cables.

A tool designed to form a stepped cable end in a coaxial cable, comprising:
- a blade assembly supported in a housing by a first cam and a second cam, wherein:
- each cam is rotatably connected to the housing and has a spiral track;
- the blade assembly is adapted to move along the spiral tracks;
- and
- the motion of the blade assembly forms one or more cuts in the coaxial cable, said cuts corresponding to the stepped cable end.
