High Speed Steel | 1.3247 | M-42

1.3247, also known as M-42, is a cobalt-alloyed high-speed steel (HSS) celebrated for its outstanding hardness, wear resistance, and ability to retain cutting edges under extreme conditions. With its high cobalt content, this material offers superior hot hardness, making it ideal for high-speed machining and cutting applications in industries such as aerospace, automotive, and precision manufacturing. Typical applications for 1.3247 include drills, taps, end mills, and saw blades that require exceptional durability and performance under high mechanical and thermal stresses. At Rosswag, we process 1.3247 using advanced open-die forging and precision machining techniques to produce components that meet stringent quality and performance standards. With its unparalleled strength and heat resistance, 1.3247 (M-42) is a preferred material for demanding tooling applications.
