Product Description
QFluids C-5300 Full Synthetic Coolant, 5 Gallon is a high-lubricity, full synthetic cutting fluid engineered for today’s most challenging machining environments. This advanced coolant uses a proprietary blend of high-viscosity index polymer lubricants that activate under the heat of machining or grinding, enhancing tool/chip lubrication precisely when needed. The result is exceptional performance with minimal residue, low carry-off, and outstanding surface finish.
C-5300 mimics the lubricity of semi-synthetics while maintaining the low-foam cleanliness and fluid life of synthetics. Safe on ferrous and non-ferrous metals, including brass, bronze, and aluminum, it prevents bimetallic corrosion and leaves a soft, protective film that won’t interfere with welding or heat treating. Ideal for CNC milling, grinding, tapping, and turning operations requiring maximum precision and reliability from their machining fluid.
