Product Description

Lubricut 4250 G is a moderate duty, synthetic coolant formulated for general machining operations on ferrous alloys and powdered metals only. Lubricut 4250 G provides an optimum balance of cooling, detergency, corrosion protection and work-piece visibility in turbulent machining operations. Lubricut 4250 G exhibits low foaming properties in most machining operations. A balanced corrosion inhibitor blend offers excellent protection against corrosion and staining of gray iron, cast iron, and ferrous alloys Lubricut 4250 G dilutions are stable in both hard and soft water. Lubricut 4250 G does not leave a sticky or tacky residue on machined parts with a fluid-like residue that will not gum up ways or stick switches. Lubricut 4250 G readily rejects most tramp oils which can then be easily removed with an oil skimmer. Lubricut 4250 G can also be utilized as a light duty grinding fluid for ferrous alloys or as a leak detection or non-destructive test fluid for ferrous metals or ferrous alloy assemblies. For operations requiring moderate lubrication and balanced corrosion protection on ferrous alloys and powdered metals, Lubricut 4250 G is an ideal choice.
