Tool steel is a type of steel specifically designed for making tools and dies. It is known for its hardness, resistance to abrasion, and ability to retain a sharp edge. These properties make it ideal for cutting, shaping, and forming materials like metal and wood. There are various grades of tool steel, each tailored for specific applications. Common types include high-speed steel, which is used for cutting tools, and cold-work steel, which is used for making dies and molds. The selection of the right type depends on the intended use and the required performance characteristics.
