1. A stock of punching tool sets, comprising:
a plurality of punches having different, respective cross-sections; and a die having a height measured in a punch entry direction with respect to the die, the die defining an orifice having a smooth wall that extends in the punch entry direction at an acute relief angle and having a cutting edge that forms a cutting edge cross-section, wherein a first punch of the plurality of punches having a first cross-section and the die in a predecessor state form a first tool set, the first cross-section of the first punch being smaller than the cutting edge cross-section of the die in the predecessor state, and wherein a second punch of the plurality of punches having a second cross-section and the die in a reprocessed state form a second tool set, the second cross-section of the second punch being smaller than a reprocessed cutting edge cross-section of the die in the reprocessed state, and wherein the die, in the reprocessed state, has a reprocessed height that is less than the height of the die in the predecessor state, and the reprocessed cutting edge cross-section of the die in the reprocessed state is larger than the cutting edge cross-section of the die in the predecessor state according to the acute relief angle, such that the second cross-section of the second punch is different from the first cross-section of the first punch. |
