摘要
A cutting tip for a drilling tool includes a cemented carbide cutting base, a diamond element supported by the cutting base, and a bonding layer formed between the cutting base and the diamond element in order to bond them. The bonding layer includes diffusion layers and in 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 diamond or the cement carbide.
