Mobilmet 443
Mobilmet 443 is part of the Mobilmet 440 Series, a range of high-performance, oil-based cutting fluids developed for moderate to heavy-duty machining applications. These fluids are formulated using high-quality base oils combined with chlorine-free additives to provide effective and reliable machining performance across a wide variety of operations. The formulation is non-corrosive and non-staining, making it suitable for use on both ferrous and non-ferrous metals while maintaining a clean and efficient working environment.
One of the key advantages of Mobilmet 443 is its excellent machining capability in demanding operations. The formulation helps improve tool life, reduce downtime and enable higher feed rates and machining speeds. This contributes to increased productivity and improved operational efficiency, particularly in more challenging machining processes.
Mobilmet 443 also delivers excellent surface finish and dimensional accuracy. Its lubricating properties help reduce friction and heat generation during machining, resulting in smoother finishes and fewer rejects. This can reduce the need for secondary finishing processes and improve overall product quality.
Another important benefit is its multi-service capability. Mobilmet 443 can be used not only as a cutting oil but also as a machine tool lubricant and, in certain applications, as a hydraulic fluid. This versatility helps reduce cross-contamination issues, simplify fluid management and lower overall inventory and maintenance costs.
Mobilmet 443 is formulated to minimise oil mist formation, contributing to a cleaner and safer working environment. It also provides resistance to corrosion and staining, ensuring high-quality finished components and reliable equipment protection during operation.
Mobilmet 443 is recommended for machining non-ferrous metals and their alloys, as well as normal to difficult-to-machine steels including carbon steels, cementation steels and high alloy steels. It is suitable for a wide range of moderate to heavy-duty machining operations where performance, precision and durability are critical.
Physical characteristics include ISO VG 15 viscosity grade with kinematic viscosity of approximately 15.3 mm²/s at 40°C and 3.8 mm²/s at 100°C. Mobilmet 443 has density of approximately 0.86 kg/L at 15°C, flash point of approximately 170°C and pour point of approximately −33°C. The oil delivers reliable machining performance, extended tool life and high-quality surface finishes in demanding applications.
