  • Performance enhancing sulfur and chlorine provide anti-weld properties and extreme pressure resistance for
    improved performance and superior finishes.
  • Extremely high concentration of metalworking additives provides maximum cutting ability and value.
  • May be used either straight for difficult machining applications or as an additive to improve straight cutting oils.
  • Replenishes additives in cutting oils where dilution by lubricating and hydraulics oils occur.
