It is shown that by varying the composition structure in the coating layers and composition of layers in the coating can achieve a significant increase in health tool than a simple composition of the coating layers. This allows you to create (design) is the most efficient process of manufacture of cutting tools for the specific conditions of its operation. If operating conditions are significantly different, it is advisable to create an arsenal of technological processes of manufacturing tools, including a variety of technological methods of hardening of the tool material by the coating.
