High-speed steel (HSS) is a versatile material used for cutting tools and other applications in the metalworking industry. It is a type of tool steel that has been developed for modern machining applications by combining high levels of wear resistance with the ability to maintain a sharp cutting edge.

High-speed steel is made up of an alloy of iron, carbon, and several other elements such as tungsten and molybdenum. The presence of these elements creates an alloy that is harder than regular carbon steel and maintains its hardness even at higher temperatures. This makes high-speed steels the obvious choice for machining applications that involve high-speed tooling, as they can withstand the high temperatures generated by the process.

High-speed steels are often used in cutting tools such as drill bits and taps, as well as reamers, end mills, and countersinks. The strength and wear resistance of high-speed steels also makes them suitable for cold forming tools, such as punches and dies, as well as for creating stamping and forming tools.

High-speed steels are also commonly used in creating punches for high-speed stamping of thin steel sheets. They are also used in some plastic injection molds, and are antimony, cobalt, and nickel based alloys.

Because of their ability to withstand higher temperatures, high-speed steels are also often used for cutting tools in high-temperature processing applications, such as machining titanium or stainless steel. They are also used in the production of components such as turbine blades and roller bearings that must perform under high-speed and high-temperature conditions.

High-speed steels are generally available in two different forms: M2 and M4. M2 is a high-carbon, high-chromium steel that is highly shock-resistant and provides superior wear resistance. M4 is a high-carbon, high-chromium steel with a higher level of wear resistance than M2, but lower shock resistance.

High-speed steels are a versatile material that can be used for a variety of machining and manufacturing applications. Their ability to maintain a sharp cutting edge and superior wear resistance makes them ideal for high-speed tooling and other machining applications.
