High Speed Steels are mainly used as tools for machining metals and are characterised by their high hardness and wear resistance.

Common tools are drills, mills, hobs and broaches.

To achieve the required advantages in comparison to unalloyed steel, Molybdenum, Tungsten, Vanadium, Chromium and Cobalt are used as alloying additives.
