New high-performance rhenus EU 12-O oil grinder offers reliability and high efficiency process
Rhenus Lub introduces high-performance grinding and cutting oil rhenus EU 12-O, an economical lubricant proven in a practical test at a major automotive supplier.

Optimised for use in the automotive industry: new high-performance grinding and cutting oil rhenus EU 12-O
Universal alternatives to mineral oil-based lubricants
Rhenus EU 12-O is based on pioneering gas-to-liquid (GTL) technology. With a very narrow boiling range, the machining oil is not only free of aromatics and odourless but also impresses with its improved lubrication performance and optimised foaming behaviour. This universal, high-performance grinding and cutting oil is suitable for challenging tasks such as the grinding of carbide metals and gear components as well as the machining of special alloys. As such, it is an ideal alternative to the conventional mineral oil-based lubricants that are still commonly used – above all in the automotive industry.
Stable performance even in challenging grinding processes
In the test at a renowned automotive supplier, rhenus EU 12-O demonstrated its strengths for gear manufacturing in the following disciplines: superfinishing, gear honing, external circular grinding and hob grinding. Compared with other products, it achieved significantly better results in terms of cooling performance, foaming behaviour and lubricating effect as well as very low evaporation losses. Thanks to its excellent miscibility, the changeover from previously used products to rhenus EU 12-O went very smoothly. Moreover, the grinding oil impresses with its high process reliability, and its low consumption contributes not only to cost savings but also to greater sustainability.
Exemplary in terms of environmental protection and occupational safety
When it comes to environmental protection and occupational safety, rhenus EU 12-O also puts in an impressive performance, as it is free of chlorine and zinc and has the lowest water hazard class (class 1). Given its low evaporation levels, it produces less oil mist, and its relatively high flash point – in excess of 200°C – also leads to greater operating safety.
The advantages of rhenus EU 12-O at a glance:
- High process reliability thanks to performance reserves
- Excellent cooling and lubricating performance
- Reduction of process costs, including thanks to lower servicing, filter and energy costs as well as longer tool service life
- Exemplary in terms of environmental protection as well as occupational and operating safety.
