Abstract:
A wellbore cleaning tool for removing irregularities along the inner surface of a wellbore tubular may include a top sub, a cutting assembly, and a bottom sub. The tool is operable to remove irregularities, such as debris, burrs, and jagged edges, along the inside of the wellbore tubular, and thereby provide a clean, inner surface finish. The tool may be actuated into a retracted position, an extended position, and/or a deactivated position.
