Abstract:
1. A method for manufacturing a cutting tool having a tool holder to which a cutter is separably attached, comprising: providing a metal base body having a configuration different than a final cutting tool configuration; forming successive layers of metal onto the metal base body, comprising: removing metal from the applied layers to finish the tool holder to the final cutting tool configuration; enclosing the side boundary with a solidified upper boundary by melting a portion of the metallic powder of a vet further one of the success applied layers onto the side boundary to create a closed boundary formed by the lower boundary, side boundary and upper boundary, the closed boundary permanently encapsulating within the closed boundary the non-solidified metallic powder portion applied with the further ones of the successive applied layers and surrounded by the side boundary such that the closed boundary is at least partly filled with the non-solidified metallic powder which remains non-solidified upon completion of the cutting tool to act as a dampener.
