High performance high-speed steel (HSS).

High-alloy steel used for the manufacture of cutting tools e.g. drills, milling cutters and chisels

Ordinary tool steel loses its hardness since around 200°C
High-speed steel retains its hardness up to around 600°C.

Why is this important?

• This material is designed for heavy-duty use and is employed where durability and performance are essential.
