Witcol DL 81 is a highly chlorinated extreme pressure (EP) type oil with fatty oils and free sulphur, making it ideally suited for most severe driving conditions. At the drawing periphery, when the surface of the tube bar is in contact with the die, there is a chemical reaction on the metal surfaces whereby a nascent metallic chloride layer of molecular thickness is formed. This feature is important in the high speed drawing process of steel for extending the die life and improving the surface finish.
