A downhole cutting tool includes a tool body and a plurality of cutter knife sets, each of the plurality of cutter knife sets configured to extend outwardly to separately perform a pipe cutting operation. A first cutter knife set has a diameter in an extended position larger than a diameter in an extended position of a second cutter knife set. A method includes running the downhole cutting tool into a wellbore, deploying the first set of expandable cutting arms to an extended position and engaging the extended expandable cutting arms with a first work piece, rotating the downhole cutting tool and cutting the first work piece, deploying the second set of expandable cutting arms during a single trip into the wellbore to an extended position and engaging the extended expandable cutting arms with a second work piece, and rotating the downhole cutting tool and cutting the second work piece.

Multi-cycle pipe cutter and related methods

A downhole pipe cutting tool includes a tool body having a piston assembly disposed in a central bore thereof, wherein the piston assembly is configured to translate longitudinally along the central axis of the tool body, and a plurality of cutter knife sets. Each of the plurality of cutter knife sets includes at least two individual cutter knives circumferentially spaced about a central axis of the tool body and is configured to selectively engage with the piston assembly to extend outward to perform pipe cutting operation.
