58A507 - Walter Coolcut 400 U Semisynthetic Coolant 20L

Maximize Machining Precision with Coolcut 400 U

Machinists and fabricators understand that tool life and part quality are directly influenced by thermal management. The Walter Coolcut 400 U (20L) is a high-performance, water-miscible coolant designed to optimize metal removal processes. Whether you are running a standalone lathe or a centralized grinding system, this semisynthetic fluid provides the lubricity and cooling power necessary to tackle tough jobs. Its advanced formulation bridges the gap between the cooling properties of synthetics and the lubricating benefits of soluble oils.

When working with difficult materials like stainless steel or aluminum, chip welding and built-up edges can ruin a part. Coolcut 400 U is engineered to prevent these issues by providing a robust lubricating film that reduces friction at the tool-chip interface. This results in smoother cuts, tighter tolerances, and significantly extended tool life. For grinding operations—including surface, centerless, and profile grinding—the fluid's low-foaming nature and rapid heat removal prevent thermal damage to the workpiece, ensuring structural integrity is maintained.

Operational efficiency is further improved by the coolant's cleaning properties. A clean machine is a precise machine. Coolcut 400 U offers excellent detergency, keeping grinding wheels open and preventing fines from settling in the machine bed. This "washing action" ensures that the cutting zone remains visible and free of debris. Additionally, because it is free of bactericides, it is gentler on the skin and less likely to cause dermatitis, a common complaint among machinists exposed to fluids daily.

This 20-liter supply is perfect for filling individual sumps or topping up smaller central systems. It mixes easily with water to form a stable, long-lasting emulsion that resists separation even under high-pressure delivery. By choosing Walter Coolcut 400 U, you are investing in a fluid that protects your expensive machinery from corrosion, safeguards your operators, and ensures your finished parts meet the highest standards of quality.
