A new approach to the improvement of cutting tool life by multilayering structure of tool materials is proposed instead of traditional one which uses mainly homogenous tool materials. The simplest multilayered structure of tool material, which is consisting of thin rake layer of conventional sintered carbide of type K10 and base material supporting the rake layer, was developed by using the hot isostatic press method (HIP). The study was aimed at determining proper base material and proper rake layer thickness. As a result, it was found in case of stainless steel machining that low carbon steel was the most suitable material as base material supporting the rake layer of sintered carbide within the materials tested in this study.
