Cutting Oil Additive is Soluble Cutting Oil Additive. It is a brown color, napthenic or paraffinic oil soluble, a premium, cutting oil additive. It is a true synthetic metalworking coolant capable of easily handling most grinding, sawing, turning, boring, milling and drilling operations. Cutting Oil Additive forms a stable translucent solution over a wide range of water hardnesses and temperatures. This clarity greatly enhances workpiece visibility. This unique formula is non-corrosive to steel, cast iron, brass, copper, aluminum and carbide tooling. It leaves a light, oily, film that provides short-term indoor rust protection and, unlike other synthetic coolants, lessens the problem of sticking on machine ways and slides. It contains lubricity, defoaming and corrosion preventive additives. The latest and most effective bacterial protection is provided to prevent rancidity. Its emulsifier mixes readily with water to form stable emulsions and has best rust-preventative properties. It is inhibited against foaming. This product is suitable for a wide range of metal cutting and grinding operations. It will effectively remove heat from the work piece and can be applied as a stream, or in mist form.
