Two new metalworking fluids from Chemtool Inc. aim to improve machining, grinding and central systems operations. Nusol 21 MW is formulated with a preformed emulsion based on a high viscosity and high molecular weight base oil that enhances cooling and offers improved hard-water stability. The product provides corrosion protection to tools, parts and equipment and separates rapidly from tramp oil, and can be used to replace synthetic and semi-synthetic metalworking fluids in machining of cast iron and steel. Lubricut 4284 coolant delivers corrosion inhibition, heat transfer for longer tool life, resistance to water buildup that can cause bacterial growth, and improved detergency for clean finishes on aluminum and other ferrous and non-ferrous alloys.
