Product Description

Tool steel
As its name implies, tool steel is intended for the production of tools for material processing
and machining, such as drills, milling cutters, files, threading dies, knives, hammers, plastic
injection moulds, etc. It is characterised by high hardness, high strength, and a very high quality.
It is characterised by high hardness, abrasion resistance and low deformability. Depending on
the working conditions, a distinction is made between cold work tool steel and hot work tool steel.
Further subgroups are carbon tool steel and HSS high-speed tool steel. The latter is mainly used
to make drills, saws or threading dies.
