Koolkut EP

Product Description

KoolKut EP is a multi-purpose EP Nitrite free emulsifiable metal working / cutting fluid containing a highly sophisticated system of extreme pressure additives, anti-foam, anti-rust and anti-bacterial agents which forms a stable milky white emulsion when added to water.

The anti-foam EP additive is a non-silicone, non-ionic, mineral hydrocarbon based foam control agent. Because of its chemical nature and resistance to “plating out”, the additive produces long term stability both in the concentrate and the resultant fluids. The absence of silicone eliminates the possibility of “fish eyeing” in subsequent processes such as painting, anodising and powder coating.

The EP additive is a chlorine based branched chain, near pure compound. The additive is not genotoxic, resulting in its acceptance by General Motors (International) for use in its plants.


Basically, water soluble emulsions are used in operations where the necessity for good cooling outweighs the need for lubrication.Other effects such as economy, corrosion inhibition, disposal of spent coolant, etc. must be considered and may have a decisive effect on the choice of cutting fluid.

An intrinsic characteristic of KoolKut EP is its inbuilt protection against bacteria. This is more effective and longer lasting than the proteos offered by added bactericides.

To produce an homogeneous emulsion, KoolKut EP should always be added to water (with agitation). DO NOT add water to the oil.


For general machining requirements a concentration of 1 part KoolKut EP added to 20 parts of water (5%) will give good results on free machining requirements. A concentration stronger than 1 part oil / 10 parts water (10%) is seldom necessary as performance is not significantly improved beyond this level, while detrimental effects such as foaming can be created.


When used as a grinding fluid, KoolKut EP should not be used at a weaker concentration than 1 part oil / 50 parts water (2%). Weaker concentrations can significantly reduce the protection against corrosion. Conversely, stronger concentrations may result in clogging of grinding wheels and glazing of the work piece.
