Abstract: In a plug an abandon environment with casing and a tubular string running through the casing a tool is placed at a desired location for a severing of the inner tubular. A first set of blades is extended from a housing to cut radially until the inner tubular is severed. A second set of blades are then extended for axial milling with a reach limit of the outside wall of the severed tubular at a location between upsets. As the axial milling reaches an upset, the second set of blades is allowed to retract and a third set with a longer reach is extended to axially mill the upset. Thereafter the third set of blades is allowed to retract and the second set is extended to continue axial milling. The second and third sets of blades can be reversed so that initial axial milling can be at the upset rather than between the upsets followed by milling between the upsets with the shorter reach blades.
