M-910 Is a Concentrated Water-Soluble Cutting Coolant, Non-Staining Metal Working Fluid that is recommended for use in grinding and other high speed light to heavy duty machining operations on both ferrous and non-ferrous metals. It does not contain any sulfur, chlorine, nitrites, phenols, or heavy metals. It is formulated to provide maximum lubricity to ferrous and non- errous materials without the use of additives that can cause staining to copper, brass, bronze, aluminum, and other non- ferrous metals.

M-910 Possesses Excellent Cooling, Extreme Pressure, and lubricity properties that are needed for high speed machining operations. It contains surface-active ingredients in the form of polyalkene glycol synthetic base fluids, which enables the fluid to wet the metal surfaces of the tool and the work piece in order to provide a protective film for lubricating the tool and the work piece interface through a unique physical characteristic called Inverse Solubility. The Inverse Solubility characteristic works as follows.

At ambient temperatures, typically of those found in a machine sump, M-910 is completely soluble in water forming a clear transparent solution. As the Synkool M /water solution is brought into contact with the tool-workpiece interface, the heat being generated at the interface by the tool causes the polyalkene glycol portion of the Synkool M to come out of solution and form small, oil like drops. Synkool M’s lubricity and anti-weld additives that function as extreme pressure agents that reduce the coefficient of friction between the tool and the workpiece interface migrate and collect at the interface between the small oil-like droplets and the water phase. The polyalkene glycol droplets wet the surfaces of the workpiece and the tool. This results in the formation of a thin
layer of concentrated polyalkene glycol and lubricity/ anti-weld additives. The spent chips and excess Synkool M /water solution falls back into the relatively cool machine sump, where the polyalkene glycol and the lubricity/anti-weld additives go back into solution. Unlike soluble cutting fluids, the chips generated during use are not coated with a significant amount of oil that does not
re-emulsify. As a result, less of the Synkool M is lost due to dragout.

This combination of cooling and Inverse Solubility properties effectively transfers heat away from the cutting zone, thus reducing friction between the cutting tool and the workpiece. This in turn results in greater dimensional accuracy, higher turning speeds and feeds, prevention of the chips from welding to the cutting tools, improved surface finish and extended tool life.

Synkool M contains an effective emulsifier system that allows the Synkool M to be mixed with water at varying concentrations. This emulsifier system allows the oil portion of the Synkool M to be evenly and uniformly dispersed throughout the coolant mixture. This even and uniform dispersion results in a transparent emulsion that allows the operator the ability to see the workpiece being machined. Further, by being evenly and uniformly dispersed, the smoking and misting characteristics that are associated with the use of soluble cutting fluids is virtually eliminated.

This emulsifier system also provides a detergent action that allows the Synkool M the ability to break up and dislodge dirt and grit in order to keep the machine and tools clean. This detergent action also assists in flushing of the chips and fines away from the cutting area.This emulsifier system also provides a detergent action that allows the Synkool M the ability to break up and dislodge dirt and grit in order to keep the machine and tools clean.

Synkool M contains an effective broad-spectrum anti-microbial agent that allows the Synkool M to resist bacterial and fungal growth during use. This broad-spectrum anti-microbial agent unlike conventional biocides found in conventional soluble cutting fluids is not readily used up during usage. In addition, Synkool M does not contain any oils, chlorine, or other components that are
considered good food sources for bacterial growth. This means that Synkool M is less likely to sour and produce odors resulting in longer sump life and less worker complaints. Synkool M will effectively reject any tramp oil contamination allowing for easy skimming and removal of the tramp oils from the sumps and reservoirs. This results the elimination of a potential food source for the growth of bacterial and fungus in the sump and greater bio resistance to the growth of bacteria and fungus in the coolant sump.

Excessive foaming of a cutting fluid during use can result in an insufficient amount of the cutting fluid being available at the tool-workpiece interface and in maintenance problems due to metalworking fluid overflow in sumps. Synkool M contains a highly effective antifoam additive system that allows the product to exhibit low foaming characteristics. This results in a sufficient amount of the cutting fluid being available to the tool-workpiece interface, greater visibility of the workpiece and a vast reduction in maintenance problems due to coolant overflow.


M-910 is a water waste treatable product that can be safely discharged into the normal flow of the wastewater from the plant. The only time Synkool M cannot be discharged into a waste water system is if the wastewater treatment facility is not a primary wastewater treatment facility. Before being discharged into the wastewater system, all tramp oils and metal fines should be removed from the Synkool M. In some areas, it is necessary to remove all traces of alkalinity before dumping watery wastes. For these areas it is suggested the following procedure be followed:
Skim all tramp oils and remove all metal fines. To the remaining clarified water, neutralize to a pH of 7.0 by the use of muriatic acid. Approximately 2 quarts of muriatic acid should be enough to neutralize 100 gallons of a used 20:1 mixture of Synkool M. Add a small amount of acid at a time and check the progress using a pH indicator paper or a pH meter. When a pH of 7 is reached, the
spent Synkool M is ready to be discharged into the plant waste effluent.
