Mobilcut 210

Aqueous Metal Working Fluids

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 and 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.


Mobilcut 100 is a conventional milky soluble oil that readily mixes with different waters to form stable emulsions.  Its versatile performance makes it suitable for a wide range of metal cutting and grinding operations for both ferrous and non ferrous materials where economical performance is the main consideration.  It offers excellent emulsion stability and long-term corrosion protection for both components and machine tool.


Enhanced with lubricity agents, Mobilcut 140 is a long life water soluble fluid making it an ideal choice for moderate to heavy duty machining applications in the modern machine shop.  It is formulated to provide long service life and good emulsion stability and durability while helping to increase tool life and surface finish, even in difficult machining operations.  Mobilcut 140 is an ideal choice where excellent machining performance is required for a wide variety of materials and applications while being easy to monitor and maintain.


Mobilcut 250 is a high performance semi-synthetic fluid formulated to enhance performance when machining aluminum and aluminum alloys and where low staining potential is important on sensitive components.  Containing high levels of lubricity agents, it provides high machining performance of carbon and alloy steels and yellow metals.


Mobilcut 320 is an inherently stable, synthetic (mineral oil-free) metalworking fluid.  It is designed for general grinding operations where a high quality surface finish, outstanding cooling and low foaming potential are the primary requirements.  It will help maintain free and open grinding wheels for maximum performance and shows a marked stability for long service life.
