HSS M2: The High-Speed Steel That Every Metalworker Needs

High-speed steel (HSS) is a popular material used in the manufacturing of cutting tools such as drills, taps, and end mills. It is known for its ability to withstand high temperatures and retain its hardness even at high speeds. Among the different types of HSS, M2 is one of the most commonly used due to its excellent combination of toughness, wear resistance, and machinability.

What is HSS M2?

HSS M2 is a type of high-speed steel that contains a combination of tungsten, molybdenum, and cobalt. It has a high carbon content (between 0.80% to 1.50%) and a chromium content of around 4%. This gives HSS M2 its excellent toughness, wear resistance, and heat resistance properties. It is also known for its ability to be easily processed and machined.

Why Use HSS M2?

HSS M2 is an excellent material for cutting tools due to its properties. Its toughness enables it to resist chipping and cracking, making it ideal for use in high-speed cutting applications. Its wear resistance allows it to maintain its hardness even when subjected to high temperatures and friction. Because it is easily machinable, it is ideal for manufacturing complex cutting tools.

Applications of HSS M2

HSS M2 finds its way into various applications due to its properties. It is commonly used in the manufacture of drills, taps, reamers, and end mills. These tools are used to cut and shape various materials such as steel, aluminum, and other metals. HSS M2 is also used in the manufacture of gear cutters, broaches, and slitting saws.

Advantages of HSS M2

One of the main advantages of HSS M2 is its toughness and wear resistance. It can withstand high temperatures and retain its hardness even under heavy use. It is also easily machinable, making the manufacturing process simpler and faster. Additionally, HSS M2 is less expensive than some other types of high-speed steel, making it a cost-effective choice for manufacturing cutting tools.


HSS M2 is an excellent choice for metalworkers who require a material that can withstand high temperatures, maintain its hardness and toughness, and is easily machinable. Its unique combination of tungsten, molybdenum, and cobalt, along with its high carbon and chromium content, make it an ideal material for manufacturing cutting tools. Metalworkers who use HSS M2 can expect superior performance and durability from their cutting tools, making it a worthwhile investment for any shop.
