The Roto-Split is a highly-specialized tool invented by Lucien C Ducret, the founder of Seatek Co. Inc. He was rewiring a room in his house and learned that there were no tools to cut BX cable except a hacksaw. Lucien made and tested a prototype in his basement workshop in Norwalk, CT. The result was the first successful tool to cut BX cable, the Roto-Split. This tool is used in removing the armored casing from metallic-clad electrical power cable (MC cable).

Roto-Split RS-101

The tool includes a guide or channel to hold the cable secure and uses a plier-type action to apply consistent force on a hand-cranked grinding wheel, which cuts across the spiralled aluminum, steel casing of a multi-wire cable. Once this cut is made, the sections of spiral jacket on either side of the cut may be separated by a sharp twisting action in opposite directions.

Alternatives to the use of this tool include a metal saw, mounted in a hacksaw or other saw handle, or in a reciprocating saw.
