58A509 - Walter Coolcut 400 U Semisynthetic Coolant - 1000L Bulk Tote

High-Performance Semisynthetic Coolant for Industrial Machining

The Walter Coolcut 400 U (58A509) is a premium semisynthetic coolant supplied in a large-scale 1000L tote, specifically engineered for industrial facilities requiring consistent, high-volume metalworking fluid performance. Designed to bridge the gap between the cooling properties of synthetics and the lubricity of soluble oils, Coolcut 400 U offers a versatile solution for a broad spectrum of machining operations. Its unique formulation is characterized by exceptional emulsion stability, which ensures that the fluid maintains its integrity over long periods, even under the stress of continuous operation in centralized systems or individual CNC sumps.

One of the standout technical features of this coolant is its bactericide-free composition. By eliminating traditional bactericides, Walter Surface Technologies has created a fluid that is significantly safer for operators, reducing the risk of dermatitis and skin irritation often associated with harsh chemical additives. Despite the absence of bactericides, the fluid is engineered to resist biological growth naturally through its stable chemical architecture, preventing the foul odors and degradation that commonly plague standard coolants. This results in a cleaner, more pleasant working environment and reduces the frequency of sump change-outs.

Technically, Coolcut 400 U excels in both cutting and grinding applications ranging from medium to severe duty. It provides excellent lubricity to extend tool life and improve surface finish, while its superior washing action ensures that chips and swarf are effectively flushed away from the cutting zone. This prevents chip recutting and keeps machine tools cleaner. The product's impressive filterability makes it an ideal choice for facilities utilizing fine filtration systems, as it does not clog filters or separate prematurely. Compatible with cast iron, steels, stainless steel, aluminum, and yellow metals, it serves as a true universal fluid for diverse manufacturing environments.
