A specially formulated, hand applied cutting lubricant designed to improve all day to day machining operations - whatever the metal being worked. RTD® Cleancut can be used on a wide range of non-ferrous and ferrous metals, including copper, brass and aluminium, without the risk of staining. Being oil-free, problems of excessive fuming often associated with oil-based products are overcome, so improving working conditions and preventing acid corrosion of the workpiece. The low viscosity of RTD® Cleancut means that it penetrates quickly, ensuring lubrication at the cutting edge to improve both tool life and surface finish.
