HSS or high-speed steel bits are made from carbon steel with the addition of other elements such as chrome and vanadium. This allows them to be used at high drilling speeds. HSS bits can be used to drill iron, steel and other metals such as brass, copper and aluminum alloy. They can also be used to drill plastic.
