Abstract
An apparatus for cutting and/or milling of tubulars in a wellbore, especially using coiled tubing. An elongated main body has a longitudinal bore, with a piston slidably positioned in the bore. The piston is connected to one or more operating arms which are rotatably connected to the main body. The connection between the piston and the operating arms may be a pinned connection or a geared connection, both of which provide for a positive connection between the piston and the operating arms. Cutter bases are connected to the cutter arms, with a number of cutters mounted to the cutter bases. Fluid flow down the coiled tubing and through the main body bore pushes the piston downwardly, opening the operating arms and cutter bases and permitting the apparatus to be pulled up into the lower end of a tubular string for cutting and/or milling.
