It is a known fact, that durability of cutting tools manufactured from the same material on identical know-how can differ essentially. This is possible to be explained with the difference in nuclear surface and near-surface patterns of composite materials, defined by vacancy defects. The quality and quantitative ratio established between mono vacancies, di-vacancies, and vacancy complexes influences greatly on the processes of friction and durability at tool exploitation. So, the level of vacancy defects and its distribution in a structure of a composite material determines the oxidation intensity, to a great extent, and consequently, and the resistance to adhesive interplay between conjugated surfaces. The received policy of processing of the obtained data essentially effects on the subsequent degree of correlation conjunction between life time and a cutting tool durability. At increase of short-lived component's life time the cutting tool durability of constructional steel 45 increases also. The minimum value of long-lived components corresponds to a maximum cutting tool durability established at cutting the chromium-nickel steel X18H10T. With electron-positron spectroscopy it is possible to find out a degree change of vacancy defects, and also the vacancy distributions according to the sizes and life time mutation of thermolised positrons,- and to control, in the total, manufacturing process of cutting tools.
