EDM Oil or electric discharge machining oil is high quality low mineral-based oil for use in spark erosion machining. The oil facilities the removal of waste material form work pieces using a series of sparks or controlled electric discharge. It contains base oil, extreme pressure additives that help in generating the needed spark between an electrode and the metal work piece. EDM Oil is highly suited for rough or precision machining. The quality of the oil is tested on certain parameters to ensure high product standards.
