It will punch a hole through paper, plastic or leather and the Scraparatus does all the work for you.
I used it to set the grommet It can even cut the hole (but I put one in already). I used it all the time. It even has die sets that will cut out letters and small shapes. I have a few but don’t use them much except for holes. But the most impressive thing, in my opinion is setting grommets of any size.
