PROBLEM TO BE SOLVED: To improve working efficiency by arranging plural dies in a die holder and selecting a desired die without rotating a turret table. SOLUTION: At least one of plural die holders arranged in a turret table 5 of a steel working machine is freely turnably arranged so that plural dies 13A-13C consisting of a punch P and a die D are in roughly parallel to the face of the turret table 5. A lower holder 53 provided with plural dies D is freely roatated on a holder base 50 fitted to the fitted table 5. An upper holder 63 arranged with plural punches corresponding to plural dies D is integrated with the lower holder 53. A desired die 13 among plural dies 13A-13C is freely positioned at a working position of the steel working machine. Without changing a position of the turret table 5, the desired die 13 is easily changed corresponding to a purpose.
