NISOTEC REZOL A is a new generation of carefully additive mineral oils with active sulfur intended for lubrication and cooling during metal cutting. Does not contain chlorinated paraffins. It is used for heavy machining operations, for cooling and lubrication during processing of steel, gray cast iron and their alloys. They are designed for heavy duty machining operations including broaching, serging, milling, deep drilling and gear grinding. The specific use is determined by their viscosity and strictly controlled composition depending on the type of processing, the difficulty of the operation and the desired fineness of processing.
