The state considered the issues of increasing the durability of cutting material of drilling equipment with the help of chemical-physical treatment of the cutting part of the drill bit. A mathematical model is presented for the impregnation of metals by applied accumulations and precipitates, as well as changes in the strength characteristics of the material during the exclusion of materials, due to the formation of defects of various breeds. An experimental study of samples of a rock cutting tool in a pool-type gamma-installation with sources of Co60 γ-quanta is presented. The effect of radiation irradiation with small doses of gamma rays in the imperfect region of the phases of hard alloy components, which leads to a change in the level of point defects of the Schottky-Frenkel type, is studied. As a result of this process, the density of defects decreases, the perfect area of microcrystals increases, which leads to the removal of superposition stress fields inside and along the grain boundary, and leads to an improvement in the intragranular and intergranular bonds of the emitted material. After processing the bit, an analysis of the performance of the processed bit under operating conditions was carried out, as well as a comparison of the performance of the bit. The use of radiation from the cutting part of the drill bit increases the efficiency and reduces the cost of drilling a well.
