Cemented carbides have the high mechanical properties, and they are used for not only cutting tools but also dies. The grinding is commonly used for finish machining. On the other hand, the cutting is sometimes used in the efficient processing. However, it is well known that the tool wear is very severe in cutting with the PCD tool. It is necessary to make clear the machinability in cutting the cemented carbides in detail. In this study, the turning of various kinds of cemented carbides was carried out with the PCD and the cBN tools. The influence of Co contents and tool materials was investigated.
