High-Speed Steel (HSS) is a composition metal. High-Speed Steel is made with Iron (Fe) as the base metal and the small amount of adding carbon (C), tungsten (W), molybdenum (Mo), vanadium (V), and cobalt (Co) in different proportions. According to the proportion of HSS, chemical and physical properties is varied.<\/p>\n\n\n\n

High-speed steel is not flammable, not toxic and not acidic. Therefore HSS has a higher chemical resistance to the matters. Due to the composition of materials, HSS has a higher physical stability. Therefore HSS is harder and tougher metal. <\/p>\n\n\n\n

The composition percentage of HSS will be varied in these ranges such as Iron: 76-80% , Carbon: 0.6-1.2%, Tungsten: 12-20%, Molybdenum: 1-10%, Vanadium: 1-3%, and Cobalt: 0-8%. Due to this variation, HSS has mainly two types: Molebdium high-speed steel and Cobalt high-speed steel. Under this types, there are 7 grades of HSS is available. Those are T1, M1, M2, M7, M35, M42, and M50. These grades are used in different applications and usages. <\/p>\n\n\n\n

Mainly HSS is used as the drilling and cutting tools for the power tools. Extra harder metal should be used when you need to cut and drill the HSS. The most suitable and efficient tool for cutting HSS is a carbide tipped saw blade. You can a cobalt drill bit if you need to drill the HSS.<\/p>\n\n\n\n
