The device comprises a long body (9), grip components (2) for supporting the body against the elongated object parallel with the longitudinal axis of the latter, and an edge carriage (11) movable in the longitudinal direction of the elongated object. In the carriage is a milling edge (16) extending against the elongated object and a drive arrangement (15) with associated components (26, 27) move the milling edge in the transversal direction of the elongated object. A component is provided for rotating the milling edge around a rotary axis parallel with the longitudinal axis of the elongated object. |
