<p>The present invention relates to a multi-layer tool containing PCD and PCBN and to a method for manufacturing same. More particularly, the multi-layer tool containing PCD and PCBN according to the present invention comprises: a PcBN layer; and a PCD layer in which an interface is formed between the PCD layer and the PcBN layer. A dispersing agent that lowers the sintering temperature and the sintering pressure of the PCD layer is dispersed from the interface between the PCD layer and the PcBN layer so as to form a concentration gradient. With the multi-layer tool material according to the present invention, bonding between multi-materials is possible even without a substrate and instead of the conventional use of using two tool materials, one tool material is needed to enable cutting while satisfying product standards such as those for wear resistance. Also, the process of bonding products of various materials can be facilitated and processing time can be saved.</p> |
