Castrol Syntilo 9931 BF
Castrol Syntilo 9931 BF is a mineral oil free synthetic coolant especially developed for use as general purpose grinding and light to medium duty machining fluid for ferrous metals. Castrol Syntilo 9931 BF exhibits good anti-corrosion properties coupled with a long system life. It can be used in both single sump machines as well as central systems.
Effective foam control helps maintain consistent fluid behaviour during operation, supporting reliable performance even where severe agitation is present.
The chlorine- and heavy-metal-free formulation reflects a modern approach to industrial fluid design, supporting an improved environmental profile and reduced waste disposal costs.
Castrol Syntilo 9931 BF is developed for surface, cylindrical, double disk and centerless grinding. It is also recommended for milling, turning, boring and light drilling operation on cast iron and low carbon steel. suggested core application possible application, please consult Castrol representative prior to use High alloyed – Low-medium Aluminium Titanium Tungsten Cast Iron stainless alloyed steel alloy alloy Carbide steel Grinding Milling, Turning (general machining) Drilling Reaming, Tapping Broaching.
