Abstract:

Six grades of cutting tools, five of Rockwell C 70 high speed steel and one of super grade high speed steel, were evaluated for the turning of Class H 11, chromium molybdenum-V hot work tool steel heat treated to Rockwell C 50. Performance of four grades exceeded that of the other two by a significant margin. Selection from the four grades will depend on the particular application. Consideration will have to be given to grinding cost, conditions for minimum machining costs and requirements for maximum production. Author
