Abstract
An apparatus (400) for facilitating the removal of a tube stub from a drum includes an arbor (401) configured to extend within the tube stub to be removed, and a circular, rotating cutter (402) protruding from the arbor (401). The cutter (402) is configured to score an internal surface of the tube stub along an axial direction of the tube stub. A controller (403) associated with the apparatus (400) controls the axial and rotational movement of the arbor (401) to create one or more cuts in the tube stub to facilitate removal of the tube stub from the drum.
