High Speed Steel
High speed steel (HSS) is a form of tool steel; high speed steel bits are hard, and much more resistant to heat than high carbon steel. They can be used to drill metal, hardwood, and most other materials at greater cutting speeds than carbon steel bits, and have largely replaced carbon steels.
