The paper considers the hydrodynamic limitations in the combined machining, caused by the non-rigidity of the tubular cathode-tool. It is shown that increasing the inertia moment of the cathode-tool cross section is possible only in decreasing the diameter of the hole for pumping the electrolyte. It should be noted that reducing the diameter of the hole increases the hydrodynamic losses of the electrolyte flow in the hydraulic path and, as a result, leads to a significant reduction in the range of the mode regimes. Thus, to implement the combined piercing of deep holes of small diameter, it is necessary to quantify the hydrodynamic limitations in using the tubular cathode-tool of significant length to establish the mode parameters.
