What exactly does HSS mean?

HSS is an abbreviation of 'High Speed ​​Steel'. It is a high-quality steel alloy that is used, among other things, for the manufacture of tools. High-speed steel is significantly more resistant to wear than tool steel (WS). On the packaging of many tools you will find the mention HSS; it means that those tools are made of a high-quality steel. The price of HSS tools is considerably higher than that of WS products, but this ratio is proportional to the qualitative properties.
