How tall of stack of paper can it cut cleanly?

I would agree that about 1" is the most. I would also add that it requires a significant amount of pressure pressed down on the paper before making the cut in. Meaning, it's important to hold the paper steady (as if held by a clamp) while pressing down to cut, because if you don't, the paper can move and not get a full cut from top to bottom. This is especially true with thinner paper. If you are just starting out using this machine. I would recommend starting with 1/4" stacks of scrap paper and get a feel for it before attempting to cut important paper in full 1" stacks. Also, make sure the two adjustable guides are aligned properly, sometimes these need to be adjusted depending on the size of the cut blade you are using.

Can I punch and round more than one paper? like a whole book? thanks!

We use it for vehicle magnets and business cards. You could probably round around 100-150 sheets of paper. I doubt you could do a whole book, but again depends on book.

which are the cutting dies provided? In inches please, thanks

1/2 1/4 3/8 5/8 Not a bad machine but is hard to get setup for a good cut.
