servocut S forms a milky emulsion with water and contains rust inhibitor to impart anti-rust, anti-corrosion properties and a biocide to prevent bacterial growth in the emulsion. This oil has superior cooling and lubricating properties which impart excellent surface finish and minimises tool wear. It is used in concentration of 5% and for grinding, more dilute emulsions are recommended. For stable emulsion oil should be added to water. It meets BIS: 1115 1986 specification and is recommended for a variety of cutting operations on ferrous and non-ferrous metals.
