DURALIFE ACTIVE SULFUR CUTTING OILS are recommended for machining tough ferrous alloys as well as mild steel , cast iron and all steels including low and medium carbon as well as nickel and chrome alloy types in such operations as milling, drilling, turning, grinding, broaching, thread cutting and tapping.
S A 10 is highly active and has low viscosity for severe operations such as deep hole drilling where good chip flushing is needed.
S A 20 has low additive and medium viscosity for mild general machining operations.
S A 30 has medium additive and medium viscosity for medium-to low-machinability steel and titanium. It is also a good form- and thread-grinding oil for hard steels.
S A 40 is highly active and has high viscosity for use on steels with the most difficult machinability , e.g. all types of stainless and heat-resistant steels. It can also be used in severe machining operations, such as gear shaping and internal broaching. Excellent form- and thread-grinding oil for the soft ,tough, or stringy steel alloys.
S Since they contain a large amount of active sulfur , these oils are not recommended for machining cooper, brass or aluminum due to potential staining problems.
