BOROL-5 is an universal biostable mineral oil-based emulsion coolant and lubricant. It has excellent lubrication properties. Contains EP additives and prevents metal welding on the tool blade.
BOROL-5 is used for medium and heavy mechanical processing of all types of steel, cast iron, light and heavy metals such as: scraping, drilling, milling, thread cutting, grinding, broaching and polishing. It is especially recommended for machining centers (NC and CNC machines). Application concentrations are 4-6% mixed with water.
