58A508 - Walter Coolcut 400 U Semi-Synthetic Coolant 200L Drum

Technical Overview of Walter Coolcut 400 U

The Walter Coolcut 400 U (SKU: 58A508) is a high-performance, semi-synthetic coolant supplied in a bulk 200-liter drum, designed to meet the rigorous demands of modern industrial machining. Engineered for versatility, this fluid is compatible with a broad spectrum of materials, including cast iron, various grades of steel, stainless steel, aluminum, and yellow metals. Its formulation is distinctively bactericide-free, addressing common industry concerns regarding operator health and fluid stability without compromising on biological resistance. The coolant relies on advanced chemistry to maintain a stable emulsion over extended periods, preventing the separation often seen in lower-grade fluids.

Technically, Coolcut 400 U excels in both medium and severe cutting applications. It provides the lubricity required for heavy-duty turning and milling while maintaining the cooling properties necessary for high-speed grinding. The fluid's low-foaming characteristics and exceptional filterability make it an ideal candidate for high-pressure centralized systems as well as individual machine sumps. By promoting efficient washing, it aids in the rapid evacuation of chips from the cutting zone, reducing heat buildup and preventing chip re-cutting, which is critical for maintaining surface finish tolerances.

The absence of bactericides does not hinder its longevity; rather, the unique formulation inhibits biological growth naturally, ensuring a long sump life and reducing the frequency of fluid change-outs. This stability translates to reduced maintenance downtime and lower disposal costs. For facility managers and manufacturing engineers, Coolcut 400 U represents a consolidated solution that simplifies fluid management across diverse machining cells.
