Abstract: A device for driving inserts into pieces of sheet metal includes a punch (1, 100) having a longitudinal axis of symmetry (5, 105), a thrust surface (9, 109) and a through hole extending along its longitudinal axis (5, 105) which constitutes a supply duct (6, 106) for the inserts. The through hole (6, 106), extends through the thrust surface (9, 109). A thrust rod (50, 150) applies a driving force to the inserts to move them into position in front of the thrust surface (9, 109) of the punch (1, 100). The thrust surface (9, 109) drives the head (42, 142) of the insert (40, 140) into a piece of sheet metal (30, 130) through a hole (31, 131) while plastically deforming the periphery of the hole (31, 131) which interfaces with the head (42, 142).
