Black Oxide: A black finish is achieved by steam tempering - a thermal process which imparts a non-metallic surface to the tool. This surface is porous and by absorbing lubricant, helps prevent rusting, reduces friction and cold welding, resulting in increased tool life. Steam tempered products can successfully be used at slightly increased machining rates or on more difficult to machine materials.
