Midcut 4150 is an extreme pressure oil developed for use on steel and non ferrous alloy metals in a wide range of high pressure and performance machining applications. The product is designed for heavy duty general machining and grinding including deep hole boring, broaching and gear manufacturing of ferrous and non ferrous materials.

Midcut 4150 is based on high viscosity index base oils and advanced synthetic esters combined with high performance inactive sulphur EP and lubricity additives. The product also contains antioxidant additives to extend the life of this high performance neat cutting oil.

Midcut 4150 will give a number of benefits when machining particularly difficult materials e.g. stainless steel on sliding head machine tools, (Star, Citizen, Index). In addition to those described on this sheet the machine speeds and feeds can be increased which reduces the time taken to complete production runs – which frees machine time to increase machining capacity. Midcut 4150 can be used for all forms of grinding, is suitable for use as a lubricating oil where a viscosity grade of ISO 15 is acceptable.
