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

Keep Your Shop Running Cool and Efficient

For fabricators and machinists who demand reliability from their equipment, the Walter Coolcut S-30™ Cutting Lubricant (20L Pail) is the ultimate solution for keeping your saws, drills, and mills running smoothly. Heat is the enemy of any cutting tool; it dulls blades, ruins drill bits, and warps materials. Coolcut S-30™ fights back with a powerful water-miscible formula that mixes easily to create a stable, milky emulsion. This coolant doesn't just wash away chips; it actively lubricates the cutting zone with high-quality oils and Extreme Pressure additives, ensuring your expensive tooling lasts longer and cuts cleaner.

Whether you are working on a custom aluminum fabrication, a stainless steel production run, or general mild steel repairs, this single coolant handles it all. You don't need to swap out fluids for different jobs. It is designed to prevent the "built-up edge" that often ruins surface finishes on aluminum, while providing the heavy-duty lubricity needed for tough steels. Plus, Walter has formulated this product with the operator in mind. It is completely chlorine-free and free from harsh bactericides, making it safer to handle and much more pleasant to work around than traditional, foul-smelling sulfur-heavy oils.

The 20-liter pail is the perfect size for refilling machine sumps or mixing into smaller dispensers for manual application. It dilutes up to 1:30 with water, meaning this single pail produces a massive amount of usable coolant, offering incredible value for your shop. The formula also includes rust inhibitors, so you don't have to worry about your machine tables or finished parts flashing over with rust after the job is done. Upgrade your metalworking game with a coolant that works as hard as you do.
