A turret punch press (1) includes an upper turret (5) for holding punches (P) and a lower turret (7) for holding dies (D). The diameter of the lower turret (7) is larger than that of the upper turret (5) so that a punch exchange position (61) and a die exchange position (61), which are opposite to a punching position (21), are separated away from each other. This arrangement enables the die to be exchanged from above the same, expands the freedom of designing of dies, improves workability, and realizes an automatic die exchange in an automatic index station.
