A drilling tool is the most important and highly loaded element of a drill rod which determines the efficiency of blast hole drilling. To improve the design of separable drilling tools (SDT), it is required to have complete information on the loads acting on bit elements. The stress-strain state of a separable cutting rotary bit (DRDF-244.5-2) was studied in ANSYS using finite-element modeling technology. Calculations were performed under maximum drilling machine and borehole bottom loads which were unevenly distributed. The article presents distribution results for fields of equivalent stresses occurring in the bit body, rotation axes and tooth-disk mills with double-row carbide cutting structures. The performance of bits under various operating conditions is analyzed.
