Mobilcut 260

Aqueous Metal Working Fluid

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.

Mobilcut 260 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 especially for soft waters and is resistant to foaming, even in high pressure systems.

Although containing only very little amount of stabilizers, it is extremely tolerant against dirt and contamination and therefore offers extended coolant life relative to conventional soluble oils while easy to care and maintain. Mobilcut 260 is free of Boron and Boron compounds.

It offers an outstanding and sustainable corrosion protection and very good wetting and detergency properties. Its base oil selection together with EP additives and lubricity agents offers a high degree of machining performance. Mobilcut 260 complies with VDI 3035 which means good compatibility vs. machine parts, paints as well as seals and isolation materials.

Mobilcut 260 is proved to have no particular dermatological relevance.

Features and Benefits

Mobilcut 260 water miscible cutting fluid is designed to help increase the productivity of modern machine shops by providing high performance features.

FeaturesAdvantages and Potential Benefits
Extremely tolerant against dirt and contaminationsEase of use and maintenance, less risk for unpleasant odors
Very little amount of stabilizersBetter acceptance by operators
Suitable from very soft to hard waters (5°dH up to 60°dH)Low Foaming, high stability, problem solver 
High degree of corrosion protectionReduces machine maintenance and rework of materials
Wide range of machining applicationsPotential to consolidate products and reduce inventories
Suitable for a variety of materials including Copper Alloys 
 and Aluminium.
No stain on finished pieces



Mobilcut 260 is a high performance, semi-synthetic cutting fluid for virtually all machining operations on metallic materials. It especially enhances performance when machining aluminum and aluminum alloys and where low staining potential is important on sensitive components.

Mobilcut 260 is suitable for the machining of copper alloys. During the machining of copper alloys, the color of the emulsion might turn into green however there will be no staining on work pieces.

Minimum concentration should be 5%. On difficult applications or materials the concentration can be increased up to 10%. Water hardness should range from 5°dH up to 30°dH. Exceptionally water hardness up to 60°dH is possible. Mobilcut 260 is problem solver at extreme soft water (5°dH) and where an explicitly tolerant and resilient emulsion against dirt and contaminations is needed.
