Advanced Cool 4321

Advanced Cool 4321 is a high-performance, semi-synthetic coolant formulated for precision machining of ferrous alloys, aluminum, and yellow metals. Its optimized synthetic/oil blend delivers exceptional heat dissipation and boundary lubrication, enabling outstanding surface finishes and extended tool life in both light and heavy-duty operations. Advanced Cool 4321 features a robust bio-resistant package that resists degradation from bacterial and fungal contamination, supporting consistent sump life in challenging shop environments. The semi-synthetic formulation balances superior detergent action with low-foaming characteristics, keeping machines clean while maintaining fluid stability in varying water conditions. This low-odor, non-corrosive coolant is safe for sensitive machine seals and compatible with a wide range of alloys. With reduced residue formation and reliable tramp oil rejection, Advanced Cool 4321 helps maximize coolant service life, minimize downtime, and reduce overall operational costs.
