ABSTRACT:
A cutting tool is provided for cutting the shell only of wire-filled corrugated flexible plastic electrical conduit of the type known to the trade as `ENTX`. The tool features a blade so spaced relative to an indexing device as to cut through the shell of the conduit proximal its maximum outside radius while the indexing device engages the conduit at an axial location proximal its minimum outside radius, said indexing device may also act as a stop to prevent the penetration of the blade beyond a predetermined radius in fixed relationship to said minimum outside radius.
