Mobilmet 400 Series
Premium Non-Corrosive to Copper, Moderate Duty Straight Cutting Oils
Product Description
Mobilmet 400 Series products are high-performancemulti-purpose cutting oils. They are chlorine-free, non-staining
and non-corrosive. They are designed for light to moderate duty cutting operations and they are also suitable
as machine tool lubricants and for use in light duty hydraulic systems. They are formulated from high quality
base oils and select additives to provide effective machining performance in a wide variety of operations of both
ferrous and non-ferrous metals. The oils are light-colored and transparent so that the work area can be clearly
seen at all times. The higher viscosity Mobilmet 420’s are formulated to prevent the formation of oil mist in the
vacinity of the machine tool.
Mobilmet 400 Series fluids are resistant to foaming, even with excess splashing so that superior performance
is provided in the machine tool lubrication system. With relatively low pour points and high viscosity indexes,
they are not difficult to dispense in cold conditions and provide adequate film strength in hot-running machine
tool bearings under load.
Features and Benefits
In addition to their machining performance characteristics, the MobilMet 400 Series fluids are multi-purpose in
nature which helps reduce the problems associated with cross-contamination, thus improving production and
reducing rejects. They are formulated using chlorine-free additives reducing the environmental impact of disposal
and spillage. The Mobilmet 400 Series fluids control built-up edge and protect the tool tip from wear. They provide
improved surface finish that may eliminate the need for finish turning or forming before grinding.
Features and potential benefits of Mobilmet 400 products include:
Features Advantages and Potential Benefits

1 of 2
Mobilmet 400 Series fluids are recommended for a wide range of machining operations on all types of metals.
They can be used as multi-purpose oils when a common fluid is required for machine tool lubrication and as a
hydraulic fluid assuming proper viscosity selection.
• Mobilmet 411 is recommended for machining aluminum, magnesium and copper, brasses and bronzes.
It is particularly suited for deep hole drilling and similar high-speed operations. It can also be used for
high-speed, light feedmachining of screw stock steels and as a lubricant for high-speed spindles
• Mobilmet 423 and Mobilmet 424 may be used with all of the metals covered by Mobilmet 411 and, in
addition, they are recommended for steels and cast irons having a Brinnel hardness up to 200. They can
be used for severe cutting operations of difficult-to-machine non-ferrous alloys such as silicon-copper,
silicon-bronze and copper-nickel. They are very effective lubricants for the machine tool lubrication system
under a wide range of temperature conditions
• Mobilmet 426 and Mobilmet 427 are recommended for critical machining of non-ferrous metals and
automatic operations on materials having a Brinnel hardness up to about 300
