HSS-High Speed Steel
HSS is often used in power-saw blades and drill bits. it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high-speed steel. HSS grades generally display high hardness (above Rockwell hardness 60) and abrasion resistance compared with common carbon and tool steels.
