Claim:
A tool for processing plate-like workpieces, the tool comprising: a first tool part and a second tool part, which are movable towards one another in a direction of travel for processing a workpiece between the first and second tool parts, and are relatively rotatable with respect to one another about a positioning axis; the first tool part comprising a first cutting edge that is provided as a rectangular cutting edge of a rectangular punch; and the second tool part comprising a first counter cutting edge and a second counter cutting edge, the first counter cutting edge delimiting a first rectangular opening of the second tool part only on one side and the second counter cutting edge surrounding a second rectangular opening of the second tool part thus forming a rectangular counter cutting edge; wherein the first cutting edge and the first and the second counter cutting edges are positioned and configured such that, with the first and second tool parts in one relative rotational position, the first cutting edge and the first counter cutting edge are positioned to cooperate with one another to produce a straight cut in a plate-like workpiece therebetween, and such that, with the first and second tool parts in a second relative rotational position, the first cutting edge and the second counter cutting edge are positioned to cooperate with one another to punch a rectangular region out of a plate-like workpiece therebetween.
