Abstract: The stress-strain state (SSS) of a demountable drilling bit with toothed disk mills and two rows of hard-alloy cutting structure (DRDF-244.5-2) was studied using finite element simulation technique in the Ansys software with a statistical application of the workload complex. Strength calculations of SSS are made for the condition of maximum loads acting on the bit from the drilling rig and the downhole, and their uneven distribution through the bit elements. The study presents the distribution of fields of equivalent stresses appearing in the bit body, axes of rotation and toothed disk mills with two-row hard alloy cutting structure.

Key words: axial force drilling of blast holes drilling tools stress-strain state applied loads calculation model fields of equivalent stresses
