KOOLRite 2290 Long Life Coolant – 5 Gallon Pail

KOOLRite 2290 is a premium semi-synthetic soluble oil coolant engineered for demanding machining operations. Designed for severe cutting applications and difficult-to-machine alloys, it delivers outstanding lubrication, cooling performance, and corrosion protection while helping extend coolant life and reduce maintenance.

Unlike traditional soluble oils, KOOLRite 2290 utilizes advanced BioArmor® Technology to naturally resist bacterial growth without relying on added biocides. The result is a cleaner machine, longer sump life, improved operator comfort, and lower overall operating costs.

Its tramp oil rejection properties help deliver cleaner coolant directly to the cutting zone, minimizing residue on machine surfaces and improving machining performance.
