ABSTRACT:
A cutting tip for a drilling tool includes a cemented carbide cutting base11, a diamond element12supported by the cutting base11, and a bonding layer formed between the cutting base11and the diamond element12in order to bond them. The bonding layer13includes diffusion layers S1and S2in which one or two or more metals selected from a group consisting of Fe, Ni, Co, Ti, Zr, W, V, Nb, Ta, Cr, Mo, and Hf diffuses into at least one of the cemented carbide or the diamond.
