High-speed tool steel contains 0.6% carbon, 3% chromium, and 14~18% tungsten. In addition, the emergence of these tool steels also played a role in promoting the development of modern industry.
Before the invention of high-speed tool steel, the efficiency of cutting tools and machine tools would be reduced by friction due to long-term use. However, with this tool, the tool and the cutting edge of the tool work at optimal rotational speed.
Common applications for high-speed tool steel include the production of chainsaw blades, milling cutters, milling cutters, gear milling cutters and drill bits. M2 high speed tool steel is the most common of this type.
