Steamtempered (Black finish)more +
Steamtempered (Black finish) is a process where a layer of iron oxide is formed on the surface of the tool. This layer increases the abrasion resistance of the blade, increases corrosion resistance and improves lubrication of the tool. The most effective use is for drill bits and taps.
