Multiple cutting tool
This cutting tool will cut a number of well strings within a well bore regardless of the down-hole alignment of the well strings. The cutting tool may be used in different size well strings by use of a stabilizer assembly which centers the cutting tool within the innermost well string. The structure of the cutting tool provides a governing action to restrict its outward movement by cutting progressively inwardly on the cutting surface so that the cutting surface is always in contact with the innermost well string being cut. The cutter blade assembly of the tool is pivoted into cutting position by a piston which reciprocates within the body of the tool due to a pressure differential created by a restriction in a fluid passageway which extends through the body of the tool.
