ABSTRACT:
There is now provided a tool for chipforming machining of metals and similar materials comprising a high speed steel core and a cover of more wear resistant material than the core. If the material in the core has a carbon content 0.05-0.25% lower than the conventional carbon content for the high speed steel in question, improved properties can be obtained.
