An electroerosion machining system for trepanning and drilling operations is disclosed. The electroerosion machining system includes an electrode assembly configured to machine a desired configuration in a workpiece, a power supply configured to energize the electrode assembly and the workpiece to opposite electrical polarities, an electrolyte supply configured to pass an electrolyte between the electrode assembly and the workpiece, a working apparatus configured to move the electrode assembly relative to the workpiece, and a control system to control the power supply and the working apparatus. The electrode assembly further includes an electrode body in the form of a tube-shaped body, the tube-shaped body defining a hollow interior and one or more replaceable inserts affixed to the electrode body at a working end thereof positioned adjacent the workpiece, the one or more replaceable inserts constructed so as to be selectively attachable and detachable from the working end of the electrode body.
