The apparatus comprises a body configured to be attached to downhole conveyance equipment and at least two cutter bases connected to the body and movable between a first position in which they are substantially retracted to the body and a second position in which they are extended outwardly from the body. An operating mechanism for moving the at least two cutter bases between the first position and the second position is provided. The set of one or more blades is arranged on the at least two cutter bases and is configured for milling in an uphole direction and a downhole direction without reconfiguring the at least one set of one or more blades. In an aspect and embodiment, each of the one more blades is configured for milling in an uphole direction and a downhole direction.[French]
