Mobilcut Series

Aqueous Metal Working Fluids

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 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 210 is a high quality semi synthetic water miscible metalworking fluid designed to form a translucent emulsion over a wide water hardness range.  Having a relatively low oil content, the product has good detergent, coolant and cutting properties, making it suitable for a light to moderate duty cutting and grinding applications.  Mobilcut 210’s formulation makes it particularly recommended for  the machining and grinding of cast iron while helping to maintain machine cleanliness.

Mobilcut 230 is a high performance semi-synthetic fluid that readily emulsifies in water to form a stable micro-emulsion. The product is designed for a wide range of water qualities and is resistant to foaming, even in high pressure systems. Mobilcut 230 is suitable for a range of applications on both ferrous and non ferrous alloys making it an ideal choice when consolidating metal working fluids.  The product offers extended coolant life relative to conventional soluble oils when properly maintained while maintaining a high degree of machining performance.

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.
