Abstract: In this article some results of mathematic modelling of an effluence of drilling fluid from hydraulic holes of PDC bit are presented. Distribution of velocity and pressure in borehole bottom are received, and ero- sion of interior surface of hydraulic channel of PDC bit is researched.

Keywords: PDC bit, flushing-out of well, submerged jet, modelling.
