Abstract
A punch tool includes a casing; a plurality of small-diameter punches vertically movable and circularly arranged in the casing; a plurality of large-diameter punches vertically movable and circularly arranged in the casing; a punch driver provided to be vertically movable and relatively rotatable on an upper portion of the casing; and a striker provided on the punch driver to be capable of striking the respective punches. Stripper springs corresponding to the respective small-diameter punches are provided. Since the respective large-diameter punches are arranged between the small-diameter punches, the stripper springs for the small-diameter punches on both sides of the large-diameter punch serve as stripper springs of the large-diameter punch.
