Abstract
A drilling head (1) with an axial oscillation generator, includes a mounting (2) for coupling the head to a motor for rotating the mounting about an axis, the mounting (2) having a longitudinal axis (5) coinciding with the axis of rotation of the motor, a tool holder (3), an elastically deformable element (6) for retaining the tool holder (3) in the mounting (2) and an element (7) for guiding the tool holder (3) in the mounting (2) along the longitudinal axis (5) of the mounting, wherein the mounting of the drilling head includes a controlled generator (8) of reciprocating movements in the direction of the aforementioned axis (5) positioned between the mounting (2) and the tool holder, the tool holder and the generator being connected by a longitudinal coupling member (9) suitable for damping the impacts withstood by the tool holder while enabling the transmission of the reciprocating movements.
