High speed steel (HSS) is a type of high-alloy steel that keeps its mechanical properties even at high temperatures around 500°C. The wear resistance of the steel is due to the presence of hard carbides and the martensitic structure.

 

PM tool steels are steels prepared by powder metallurgy, similar to hard metals. They are produced by sintering a powder of a given composition. PM steels offer many advantages over conventional HSS steels and are successfully used especially in milling.

 

Removing coatings from steels is not a major problem. Almost all commonly applied PVD coatings are removable without damaging the underlying HSS/PM substrate.

- Coating removal without disturbing the steel structure.

- Possibility of decoating an already sharpened tool

- Appearance after decoating is indistinguishable from a new tool
