Research of the interaction of rock-cutting tools with rock with various approaches is presented in the article. In contrast to analytical and experimental methods with their limited and costly applicability, it is proposed to use numerical modeling to better represent the mechanics of rock destruction, to visualize the stages of destruction in a short time and in a cheaper way. This article allows to get an idea that using the finite element method can get mathematical modeling of plastic deformation, assess the stress-strain state of the bit and optimize the structural elements and working conditions of the rock cutting tool, analyze the dynamics of fracture forces and others. The dynamic interaction of the drill bit with the rock in case of two cones with different arrangement of buttons on one crown is investigated. In the process of analysis, it was found that the interaction of paired buttons with rocks has a force action on the area of the rock as well as the cone of the industry bit, but in a more intensively fluctuating way, by also saving energy. Advantageously, the arrangement of the buttons in pairs has not only tensile stress in the longitudinal direction, but also in the transverse direction, contributing to a wide coverage of the fracture zone
