DNR Sparking Oils SPO-A is a high quality, low viscosity dielectric fluid designed to perform flawlessly over a broad range of metal removal rates. The low viscosity of DNR Spark SPO-A provides uniform cooling of both electrode and workpiece while allowing rapid settling of the metal particles. It works as an insulator but deionizes quickly, at applied potentials, to conduct the spark discharge. DNR Spark SPO-A is a dielectric fluid for general purpose mold and die work where good flushing, close tolerances and optimum rates of metal removal are important. It widely out-performed the common EDM fluids more than tenfold in oxidation stability characteristics, sludge formation and service life.

It is a general purpose emulsifiable metal cutting oil which forms a milky blue emulsion when dissolved with water. It is specifically formulated for use in intensive operations on ferrous metals. It is manufactured from specially selected Lube base stocks and blended along with specifically formulated Emulsifier along with other additives, lubricity agents, Corrosion inhibitors and suitable biocides, which ensure its complete dispersion in water, forming a homogenous and stable emulsion in water upto medium hardness
