This punch is certainly not the best thing that you can imagine, but you would just spend 3 times. But: Contrary to other opinions we must not always punch holes 6, the punching units can also be expanded (screw out, rotate 90 degrees, press punch, punch unit can be inferred). If you want to punch eg A5 Ringbucheinlagen, can be a punching unit simply turn it 90 degrees and positioned at the appropriate place as a stop. Thus the discussion about the lack of stop rail is eliminated.
