Abstract:
In the auger cleaning device (8) according to the invention, in the closed configuration the tool-holder support forms a pass-through opening (82) arranged for allowing the passage of a helical drilling tool (6), the cleaning tool (170) engaging with the screw of the drilling tool (6) and, actuated by the actuation system (12, 12′,12″, 4), is arranged for rotating around the drilling tool (6) following at least one of its threads (60) so as to remove the debris lying on the drilling tool (6). In the open configuration the cleaning tool (170) is disengaged from the drilling tool (6) and preferably farther from it, with respect to when it is in the closed configuration.
