53C007 - Coolcut S-30 Soluble Oil Cutting Fluid 20L Pail

High-Performance Water Miscible Cutting Lubricant

The Walter Coolcut S-30™ (SKU: 53C007) is a premium-grade, water-miscible cutting lubricant engineered to meet the rigorous demands of modern industrial machining. Supplied in a substantial 20-liter pail, this formulation is designed for automatic and semi-automatic metal removal operations where thermal stability and lubricity are paramount. Unlike generic coolants, Coolcut S-30™ utilizes a sophisticated blend of Extreme Pressure (EP) additives that activate under high loads to protect tooling from premature wear, ensuring precision tolerances are maintained even during heavy material removal rates.

One of the standout technical characteristics of Coolcut S-30™ is its versatility across material types. It is specifically formulated to perform exceptionally well on both ferrous and non-ferrous metals, including difficult-to-machine alloys like stainless steel and soft, gummy metals like aluminum. The formulation is chlorine-free, which eliminates the risk of stress-corrosion cracking in sensitive alloys and simplifies waste disposal compliance. Furthermore, despite being free from traditional bactericides—which can be harsh on operators' skin—it incorporates advanced ingredients to control bacterial growth, preventing the foul odors and emulsion breakdown often associated with soluble oils in sump systems.

The high oil content of this emulsion provides a robust lubricating film that enhances surface finish quality while simultaneously offering excellent corrosion protection for both the workpiece and the machine tool components. Its low-foaming nature ensures consistent flow and heat dissipation, even in high-pressure coolant systems. With a dilution ratio capability of up to 1:30, Coolcut S-30™ offers an economical solution for workshops looking to optimize their coolant usage without sacrificing performance. It represents a convergence of safety, efficiency, and technical excellence in metalworking fluids.
