M35
High-speed steel M35 is another grade of high-speed steel, often regarded as an upgrade over M2 due to its improved properties, particularly in terms of heat resistance and toughness.
M35 high-speed steel is generally more expensive than M2 due to the addition of cobalt, which enhances its performance characteristics. However, the improved properties justify the higher cost in applications where superior cutting performance is essential. In summary, M35 high-speed steel offers enhanced properties compared to M2, particularly in terms of heat resistance and toughness, making it suitable for high-speed machining applications where tools are subjected to extreme cutting conditions and elevated temperatures.
