An improved device for making eyelets, essentially characterized in that the horizontal transmission shaft of the clutch, carries in its terminal an eccentric cam that makes work vertically a second axis acting on the pointer that perforates the material, and because said cam comprises an eccentric bushing that by means of a connecting rod, it regulates the advance of a concentric matrix external to said drilling shaft, which is confronted with another punching die, located at the base of the bench for the positioning of the eyelets.
