The ways of improving the physical and mechanical properties of the components of a hydromonitor drill head with an integrated generator of hydrodynamic oscillations are reviewed. On the basis of the results of this consideration, an improvement of the working body of the HDD technique is proposed. On the example of 60S2A and 65G steels, the influence of different modes of heat treatment of the improved drilling head on the ultimate strength, relative lengthening, and surface hardness of the detail petal, which is the basic loaded element of the generator of hydrodynamic vibrations, is examined. The analysis of physical and mechanical properties has shown a significant increase of parameters influencing the increase of rigidity properties of the investigated hydrodynamic oscillator part, which allows us to make a conclusion about the effectiveness of its application for the increase of drill bit operational life. An experimental and analytical method was carried out to describe the increase of physical-mechanical properties of the part - petal, which is the main loaded element of the generator of hydrodynamic oscillations. Increase of durability of rock destruction tool for pilot hole laying by increasing of physical-mechanical properties of used material for individual parts of hydrodynamic oscillator.
