Mobilmet S-122

Water-Soluble Cutting Oil

Product Description

Mobilmet S-122 is a water-soluble, general-purpose cutting oil designed for moderate-duty cutting and metalworking operations. Mobilmet S-122 fluid is formulated with select base oils and fortified with soaps, sulfonates and coupling agents. It also contains stabilizers to control odor and provide long service life.

Features and Benefits

Mobilmet S-122 offers improved cooling with less smoke and reduced staining of ferrous and non-ferrous metals. It helps to create better finish and closer tolerances, with fewer rejects. With proper use, tool life is increased between required regrinds resulting in lower maintenance costs and improved equipment uptime.


Mobilmet S-122 is recommended for a wide range of machining operations on  both ferrous and non-ferrous metals.

  • Cutting and grinding operations requiring water-soluble fluids
  • Applications where enhanced cooling is desired
  • Machining and grinding operations on both ferrous and non-ferrous metals
