M35

Cobalt High Speed Steel M35

M35 is a cobalt-bearing high speed steel designed for higher hot hardness and wear resistance. It maintains cutting performance at elevated temperatures, especially in difficult-to-machine materials. The cobalt addition improves red hardness while retaining good toughness for reliable tool life. Its fine, uniform structure supports precision grinding and stable edge retention. M35 is commonly used for drills, taps, end mills, and broaches in demanding machining. It performs well on stainless steels, high-alloy steels, and heat-resistant materials. Built for productivity, M35 helps reduce tool change frequency in tough applications.
