...-purpose high-speed tool steels (such as grades Ml, M2, M7, and M10) also are used. However, better results are generally obtained with more highly alloyed tool steel grades, such as T5, T15, M33, and the M40 series. Cutting tool performance is influenced by many factors. Setup, processing methods...
