Why Choose Castrol?
Based on Castrol’s technical literature, Variocut C 334 uses refined mineral oil combined with a balanced additive system to create stable cutting conditions. The fluid provides good wetting behaviour during machining, which helps maintain tool contact efficiency. Its low viscosity profile contributes to heat removal during higher-speed applications, supporting surface finish quality on components. The absence of chlorine additives means the product fits well with plants aiming to reduce halogen-based waste while still maintaining a reliable level of lubricity.
Variocut C 334 is commonly used in turning, drilling, milling and grinding operations on a range of metals. It offers strong compatibility with yellow metals, making it suitable for mixed-metal environments. Users working with materials such as aluminium and copper alloys benefit from its clean machining behaviour and reduced staining tendency. Its stability during extended circulation helps maintain a predictable performance curve in production environments.
The product's chlorine and heavy metal-free formulation also means that Castrol Variocut C 334 is more environmentally friendly than equivalent products, and minimises disposal costs. Besides its strong environmental profile, its low viscosity and excellent wetting characteristics mean that you can use less Variocut C 334 than other products for the same effects. Increased cutting speeds leads to further savings and delivers one of the best heavy metal-free neat cutting oils on the market.
