This offering is for deep hole drilling and trepanning operations. It has been crafted withspecially selected mineral oils and contain a blend of polar, Mild and active extremepressure ep additives. These additives effectively manage the demands of the varying stressesat the the chamfers, Cutting edge and especially during the cutting process. At thehighly stressed friction points where high local temperatures thermaldecomposition of, Are obtained these additives occur. Reaction at the sliding metal surfaces takesplace giving metallic derivatives which act as solid lubricant films. Ilocut 334 containsfat and sulphur as the polar and ep additives. In deep hole drilling operations the coolant must be considered fed through the boring bar underhigh pressures. This functions as therefore essential for utilizing the right viscosity coolant to ensurerapid flushing action for clearing swarf from the boring head. This product serves as also important thatthe thickness of the fluid should permit high velocity flow and not cause entrapment orfoaming with the small holes included within the cutter head
