A black finish achieved by a steam tempering, a thermal process resulting in a porous tool coating. this surface helps to keep lubricant on the tool, particularly important on the cutting edges, thus reducing friction and cold welding. The result is increased tool life. Black
finish tools are generally recommended for ferrous applications where the oxide layer aids chip flow and heat dissipation.
