Product Description

Mobilcut is the trademark for Mobil Industrial lubricants line of high performance water miscible metal removal fluids. Formulated with leading edge base oils, additives, and emulsifiers, the Mobilcut series of non-chlorinated products provides dependable performance in a wide array of metal removal processes. The products are designed to work in a variety of hard and soft water qualities and offer low foam potential and long-term corrosion protection for machine and components. Low maintenance and inherently stable, Mobilcut products are designed for the modern machine shop where long service life, excellent machining performance, health and environmental concerns are important factors for increased productivity. These products are supplied in concentrated form and require mixing with water at the point of use. All Mobilcut products are free of formaldehyde release agents (FAD).

Mobilcut 250-New is an amine and boron free high quality micro emulsion water miscible metalworking fluid designed to form a translucent emulsion which is suitable for hard and soft water in a range of 15 – 25°dH and stable in use up to 60°dH. Fluid is designed to minimize skin irritation and provide long operation life at the same time. Particularly suitable for aluminium machining.
