Popis:	The paper is focused on the analysis of principal stress fields induced in the system of drilling tool-rock during the drilling process in immediate surroundings of their mutual contact. Various load conditions were analyzed, representing torque, loading only by axial thrust force and combined loading by concurrent action of torque and thrust force on the drilled rock.
