M42
High-speed steel M42 is another premium grade of high-speed steel known for its exceptional heat resistance, hardness, and wear resistance.
M42 high-speed steel is typically more expensive than other grades of high-speed steel due to its high cobalt content and superior performance characteristics. However, its exceptional properties justify the higher cost in applications where cutting tools are subjected to extreme conditions and require maximum performance. In summary, M42 high-speed steel offers exceptional hardness, heat resistance, and wear resistance, making it ideal for high-speed machining applications where cutting tools are subjected to intense heat and abrasion. Its superior performance justifies its use in critical cutting operations where precision and reliability are paramount.
