Abstract (en)

[origin: EP3680040A1] Multioperation friction drilling tool allowing three different final operations to be performed in the same drilling: drilling, calibration and threading. The friction drilling tool of the present disclosure has a friction self-piercing segment, a calibration segment, a thread-opening segment and a stop segment. The calibration segment allows calibrated holes to be obtained, if that is the final objective, or preparing the hole for a thread-opening operation in the material drained on the walls of the already-calibrated hole, depending on the user's choice. An embodiment of the friction drilling multioperation tool sequentially comprises a plurality of distinct axial segments: a support segment, a thread-opening segment, a calibration segment of predetermined diameter and a friction self-piercing segment, which may comprise a cylindrical stop-spacer segment.
