WebHigh-speed steel ( HSS or HS) is a subset of tool steels, commonly used as cutting tool material . It is often used in power-saw blades and drill bits. It is superior to the older high- carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness). WebHigh-speed steels, abbreviated as HSS, are a specialized class of tool steels that were named primarily for their ability to machine and cut materials at high speeds (high hot hardness). It is often used in power-saw blades and drill bits.
