Black Swan Dark Cutting Oil is a heavy-duty sulfurized-chlorinated base oil that helps cut clean, sharp threads on steel and brass pipe. It is formulated to reduce friction during the machining process, which minimizes heat generation. The result: cleaner, sharper threads, better fitting joints, and longer tool life.
