HP SYNTHKOOL 24121 is a premium low-mineral oil, water-miscible semi-synthetic cutting fluid designed to provide outstanding lubrication, cooling, and corrosion protection during machining operations. It is formulated from highly refined base stocks and advanced lubricity additives to ensure superior surface finish, longer tool life, and clean system performance. Free from chlorine, sulfur, and phosphorus compounds, this environmentally considerate cutting fluid is ideal for high-performance multipurpose metalworking applications across a wide range of materials, including ferrous and non-ferrous metals. When diluted in potable water at concentrations ranging from 4% to 10%, HP SYNTHKOOL 24121 forms a stable and clear emulsion that delivers excellent cooling efficiency and anti-rust protection even in demanding, high-speed machining environments. Its superior thermal, oxidative, and hydrolytic stability ensures that the fluid remains effective over long periods, reducing the need for frequent top-ups or replacements. The product exhibits excellent resistance to bacterial growth, preventing odor formation and maintaining fluid cleanliness in recirculating systems. Thanks to its balanced lubrication chemistry, HP SYNTHKOOL 24121 minimizes friction and heat generation between the cutting tool and workpiece, ensuring smoother operations and precision machining. It also prevents corrosion of cast iron and other metals, keeping machine parts clean and free of rust. The fluid’s enhanced wetting properties promote better chip removal, reduced tool wear, and improved component finish. With a kinematic viscosity of approximately 51 cSt at 40°C and a mineral oil content of 30%, this amber-colored fluid provides an optimal combination of cooling and lubricating characteristics. Its emulsion remains stable in both soft and hard water conditions, ensuring consistent performance under varying workshop environments. The product’s alkaline pH of around 9 further enhances its corrosion inhibition and emulsion stability. HP SYNTHKOOL 24121 is a versatile and high-performance coolant solution designed for modern machining systems that demand clean operation, long service life, and exceptional performance without compromising environmental responsibility.
