Tatmo-V is an M7 grade high speed steel with superior abrasion resistance because of its high carbon and vanadium content. It is an excellent choice for premium grade tools which require an outstanding balance of red hardness, edge toughness, and wear resistance. Increased tool life of Tatmo-V is noted in the machining of semi-hard, heat treated steel parts. Information Provided by Timken Latrobe Steel. Timken sold Latrobe in December 2006.
