A set for installing an intracardiac lead equipped with a screw in a wall of the endocardium, particularly a stimulation or defibrillation lead. This set comprises a removable stylet (50), able to be introduced inside the sheath (12) of the lead-body and mobile in translation and rotation therein. The stylet has at its distal extremity a mechanism (56) for coupling in rotation to allow the rotation (28) of the lead-head (10). The stylet (50) includes: a central core (52, 71) carrying at its distal extremity the aforementioned coupling mechanism, and at its proximal extremity a handling body (32) for handling by the physician and a hollow tube (54) axially placed around the core. The length of the hollow tube is less than the length of the core, so that the latter emerges from the hollow tube at the proximal and distal extremities of the tube, so as to allow the rotation of the core and correlatively of the coupling mechanism, by action on the handling body, primarily without setting in rotation of the hollow tube.
