ABSTRACT:
A diamond coated cutting tool that has a treated substrate and a diamond coating thereon. In the process of making the substrate, the sintered substrate is re-sintered to form a re-sintered substrate and the re-sintered substrate is chemically treated to remove cobalt on the surface of the re-sintered substrate as to form a treated substrate.
