Castrol Hysol™ 6519 (previously called Clearedge™ 6519) is a high performance semi-synthetic metalworking fluid which is chlorine and formaldehyde releasing agent free. It is ideally suited for job shops that want a single fluid to machine a variety of metals.

Hysol 6519 is a clean product that provides dependable rancidity control when used in machine tools with individual sumps. However, the durable, longlasting qualities of this versatile cutting fluid also make it an excellent choice for extended use in central systems. Hysol 6519 is suitable for large central systems and single sump machines.
