NOV Downhole Bowen Milling Tools, hardfaced with Itcoloy, sintered tungsten carbide particles, are designed to mill away stuck fish that cannot be retrieved by conventional fishing methods. Their super penetration rates results in fewer round trips. They are highly resistant to impact loads and their selfsharpening feature results in maximum useful life.

Internal and external cutters provide ways of removing long sections of casing, tubing, or drill pipe from the well.
