The article describes features of hole formation during rock breaking with acuminate cutter tooth at the high speed roller bit drilling system. The effect of the pressure pulse generated by multiple bit cutter teeth is considered. Shown the pressure variation dynamics created by bit cutter tooth in the rock matrix. The mechanism of the effect of wave processes on the rock breaking and describes the results of the wave generator application. To create the wave field in the hole with streaks, built of rocks with low strength to pressure variations, should be preferred spindle generators, which is substantially less than over-turbine generators, the pressure drop and correspondingly generated oscillations with lower pressure amplitudes.
