The article presents finite-element simulation results of the PDC drill bit’s operational stress-strain state in order to determine the most stressed and deformed areas in drill bit’s operation. Operational stress-strain state of drill bit definition is important because external diameter of the drill bit is the main operation parameter; and drill bit external diameter decreasing is a cause of drill bit failure. There were simulated operations of PDC drill bit with welded blades and a solid drill bit. The authors used the Ansys Workbench (academic license version) to specify the biggest deformation areas. They are the welding joint areas and thread area. The authors considered the dependence of stresses and strains in these areas on the thickness of a welding joint. We can conclude that bits with welded blades are more prone to external diameter deformation; they have worse performance. This fact stipulates requirements for technology improvement of manufacturing these types of bits.
