53C028 - Coolcut S-50 High Performance Soluble Cutting Oil 208L

High-Performance Machining Emulsion for Demanding Applications

The Walter Coolcut S-50 (53C028) is a premium-grade metal cutting lubricant supplied in a bulk 208-liter drum, designed to meet the rigorous demands of modern industrial machining. Engineered for automatic and semi-automatic operations, this water-miscible fluid excels in heavy-duty metal removal tasks where standard coolants fail. Its advanced formulation incorporates extreme pressure (EP) additives that significantly reduce friction and heat generation at the cutting edge, thereby extending tool life and improving surface finish quality. Unlike traditional soluble oils that may struggle under stress, Coolcut S-50 maintains a stable emulsion even under high-pressure conditions up to 1,100 psi (80 bars), making it an ideal choice for through-tool coolant systems and high-speed machining centers.

One of the standout features of Coolcut S-50 is its versatility across a wide range of materials. It is specifically formulated to handle hard-to-machine alloys such as stainless steel, titanium, and high-tensile steel, while remaining perfectly safe and effective for aluminum and other non-ferrous metals. This multi-metal compatibility allows machine shops to consolidate their coolant inventory, using a single high-performance fluid for diverse projects. The lubricant is non-chlorinated, which prevents stress corrosion cracking in sensitive alloys and aligns with environmentally responsible manufacturing practices. Furthermore, it includes extended corrosion inhibitors that protect both the workpiece and the machine tool components from rust and oxidation during and after the machining process.

Operator safety and fluid longevity are central to the design of Coolcut S-50. The formula is bactericide-free, reducing the risk of skin irritation and dermatitis often associated with harsh industrial coolants. Despite lacking bactericides, it is engineered to resist biological growth when maintained correctly, ensuring a long sump life and reducing disposal frequency. With a highly economical dilution ratio of 1:30, this 208-liter drum provides a massive volume of usable coolant, offering exceptional value for high-volume production environments. Whether you are drilling, milling, reaming, sawing, or turning, Walter Coolcut S-50 delivers the cooling and lubrication necessary to optimize cycle times and ensure precision results.
