Mobilmet Omega

Oil Based Cutting Fluid

Mobilmet Omega is high performance mineral-oil-type active cutting oils incorporating synthesised additive technology. The balanced selection of additives in Mobilmet cutting oil maximises performance over the wide range of pressures and temperatures encountered when machining difficult metals under difficult conditions. This chemically-synthesised, active additive combination also controls buildup on the tool tip, resulting in a better surface finish.

Mobilmet Omega contains the active anti-weld properties that are required for cutting difficult-to-machine metals. It is transparent on the work piece, allowing good visual inspection of machined parts. These oils, however, can discolour the surface of copper alloys. Mobilmet Omega is designed for a wide variety of metal cutting operations, severities and metallurgies. It is also formulated for ease of use and operator convenience. These attributes have resulted in this fluid becoming the product of choice for many machine shops.
