1. A generally cylindrical shaped abrasive fluid operated pipe cutting tool comprising:
a pump down ring, wherein an outermost diameter of said ring is larger than that of any other component of said tool when the tool is in dry state;
a swellable sleeve surrounding at least an outer portion of said tool, said sleeve being capable of expanding when exposed to a first oil or water-based fluid; and
a fluid flow path having, at a first upstream end of the tool, an entrance for pressurized abrasive fluid to flow into the tool, and multiple fluid ejection nozzles downstream of said swellable sleeve and of the pump down ring, said multiple fluid ejection nozzles for ejection of inflowing pressurized abrasive fluid from the first upstream end of the tool in the form of pressurized abrasive fluid jets, and one or more flow channels connecting a portion of the outer surface of the tool below the swellable sleeve and the pump down ring with the lower end of the tool.
