Popis:	The article substantiates the possibility of improving the efficiency of short-hole drilling by combining axial and moment pulses with a rotating drill cutter. The control of regime parameters of drilling, including parameters of axial and moment pulses, in order to establish rational ratios of parameters can be carried out by boring machines of the mechatronic class directly in the process of short-hole drilling. A methodology has been developed for conducting experimental studies in accordance with which experiments have been carried out and dependencies obtained that reflect the effect of the combined effect of axial and moment pulses on the penetration rate. The stress-strain state of the rock in the undercutter zone of the short-hole with the combined effect of axial and momentum pulses on the drilling tool is investigated using the method of finite element analysis.
