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. By reducing this friction heat generation is minimized. The results are cleaner, sharper threads, better fitting joints and longer tool life.
Dark Cutting Oil is formulated to work on high speed machines. For hand threading applications use Black Swan Light Cutting Oil.
Dark Cutting Oil is an anti-mist lubricant. Weather conditions will not affect the oil. The quality of the oil is guaranteed to be uniform at all times. The oil is also ideal for stripping, broaching , or milling applications.
CONTENTS
Dark Cutting Oil is formulated with 100% virgin petroleum oil, sulfur, chlorine and fat.
Sulfur and chlorine are utilized to minimize tool wear and improve part finish. In these oils, the sulfur and chlorine are attached to the same molecule to achieve a synergistic effect. Thus, these heavily fortified cutting oils are even more powerful than the sulfur and chlorine content would indicate. The presence of fat combines with the sulfur and chlorine to provide exceptional performance in high speed, light duty operations as well as low speed, heavy duty operations. The highly aggressive nature of these oils prevent their use on copper alloys unless black staining is acceptable.
