ABSTRACT:
A portable disintegrator to disintegrate a hole in a metal workpiece is disclosed. Disintegrator current and coolant are supplied to the working end of an electrode which is vibrated in advance and retract axial movements. Guide means either actually engages the workpiece immediately surrounding the hole to be formed or engages a part of the workpiece closely adjacent where the hole is to be formed in the workpiece. The main frame of the metal disintegrator may be counterbalanced for weight but is guided by hand with freedom of limited movement in two dimensions during operation of the disintegrator.
