<p>The self-drilling component includes a body with a cylindrical side wall, a self-drilling head at a first end of the body and a shank opening out at a second end. The self-drilling component includes a deformable area between the self-drilling head and the second end designed to form a flange when crimping is performed. The self-drilling head further includes a tip defined by three concurrent edges at least two of which are internal cutting edges, the tip enabling engagement of the self-drilling component, at least one external cutting edge placed at the end of the cylindrical side wall configured to cut the fibres of the composite material part, and a first surface parallel to and different from the axial plane containing the axis of rotation of the body, the first surface defining a first empty space in the self-drilling head to facilitate removal of the shavings when drilling is performed.</p> |
