ABSTRACT:
A method for forming diamond tools using CVD techniques. In one aspect, a mold is provided which has an interface surface configured to inversely match a configuration intended for the working surface of a diamond layer in a tool. An adynamic diamond mass or layer is then deposited upon the diamond interface surface of the mold, and a support layer is joined to the growth surface of the adynamic diamond layer. At least a portion of the mold is then removed to expose the working surface of the diamond which has received a shape which inversely corresponds to the configuration of the mold's diamond interface surface.
