CASTROL HYSOL T 15

Why Choose Castrol?

Castrol Hysol T 15 is a high-performance, chlorine-free, semi-synthetic, water-soluble cutting fluid engineered for general machining and grinding operations. It is part of Castrol’s renowned Hysol range, which is formulated to meet the diverse demands of modern machine shops while maintaining fluid stability and tool protection.

With a blend of mineral oil and advanced emulsifiers, Hysol T 15 is designed for cutting cast iron and low-medium alloyed steel, and delivers excellent lubricity and cooling performance in these applications. It reduces friction and heat build-up during cutting, which can extend tool life and improve surface finish. Its low foaming characteristics make it suitable for high-pressure coolant systems and modern CNC equipment, especially in soft to medium-hard water conditions.

Hysol T 15 is also designed for long sump life and good microbial resistance, reducing maintenance frequency and minimising downtime. This supports cleaner working environments and helps to prevent unpleasant odours. With extended fluid life, you can minimise maintenance and reapplication requirements, while enjoying reliable corrosion protection and emulsion stability under typical workshop conditions over the long term.
