Tools for high speed heavy cutting and other kinds of tools. Tools for cutting hard -to-machine materials and other kinds of tools. Tools for cutting ultra hard-to-machine materials and other kinds of tools. Mo type HSS General cutting tools from which toughness is particularly required, and other kinds of tools. Tools for cutting high hardness material from which comparatively high toughness is required and other kinds of tools. Tools for cutting ultra hard-to-machine materials and other kinds of tools. High speed cutting tools from which comparatively high toughness is required and other kinds of tools. Tools for cutting ultra hard-to-machine materials and other kinds of tools. General cutting tools from which toughness is particularly required, and other kinds of tools. High speed heavy cutting tools from which comparatively high toughness is required, and other kinds of tools. The standard of HSS material is speci ed in JIS. But there are many HSS materials which standard is not speci ed in JIS. Recently even the kind of HSS-P is getting wider and various. Besides, SKH10, SKH53, SKH57 and their equivalents, such Hi vanadium/hi cobalt material as contains 4-12% vanadium and 8-11% cobalt is now being manufactured. Material engineering will be developed rapidly in the future. Under such situation, there can be many cases where JIS symbols are not used, and the use of larger classi cation and their symbols is getting popular. Technical-112
