M35 Tool Steel | Skh55 | Hs6-5-2-5 | 1.3243
M35 tool steel is a cobalt-alloyed high-speed steel (HSS) conforming to W6Mo5Cr4V2Co5, 1.3243 and Skh55 standards, supplied by Dongguan Otai Special Steel Co Ltd in round bars, flat bars, sheets, plates and blocks. This grade delivers exceptional red hardness and wear resistance, maintaining 63 to 65 HRC after 4 hours at 625°C, making it ideal for demanding cutting applications. The material’s composition includes 5% cobalt, which enhances hot hardness and resistance to abrasion at high temperatures.
The steel is produced to meet international standards such as DIN, ASTM, EN and JIS, ensuring compatibility with global industrial requirements. Typical applications include drills, taps, end mills, reamers and punches, where toughness and resistance to edge collapse are critical. M35 is often selected over lower-cost HSS grades like M2 when superior performance under thermal stress is required, particularly in aerospace, automotive and precision machining sectors.
Industrial distributors and precision tool manufacturers source M35 for its ability to withstand intense cutting conditions without premature failure. The material is supplied in various forms to accommodate different tool designs, with heat treatment processes tailored to achieve hardness levels between 67 and 70 HRC. Buyers in Europe, the Americas and Asia frequently specify this grade for high-performance tools, while confirming exact dimensions, tolerances and surface finishes with the supplier to meet project-specific needs.
