Abstract (en)

[origin: WO2015110907A1] The invention relates to a drilling device (6) comprising a cylinder (61) consisting of a body (611) and a rod (612) extending along a longitudinal axis (A-A'), and a drilling component (62) connected to the rod (611), said drilling device being used to form a hole in a crust of alumina and solidified bath of an electrolytic cell by means of a back-and-forth movement of the drilling component (62) along a translation axis (T), characterised in that the longitudinal axis (A-A') is parallel to, and separate from, the translation axis (T).
