Review: Wonderful !!! (but actually 4 1/2 starts would be more accurate.) - This is a GREAT item that is absolutely built like a TANK! This thing must weigh at least 15 lbs!!! And I have no doubt that it should easily last me the rest of my life (Which I hope is more than 25 years from now). The only small gripe that I have, is the one that has already been mentioned... the biggest corner rounder bit is still just a little bit too small for my liking. Having said that, I suppose that I would also have to say that while I wish it was bigger, it's actually still quite adequate for my use (trimming 8.5" x 11" paper for a 1 inch binder.)
Review: Great Corner Rounder! - EXCELLENT Corner Rounder! One of the best I've seen and the price is spot-on! You can cut a large quantity of paper with this thing and it will cut plastic, magnetic sign material, banner material, and thin metal (aluminum). The only thing I wish it had was a 1/2" die and it would have been perfect!

## Questions & Answers

**Q: How tall of stack of paper can it cut cleanly?**
A: 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.

**Q: Can I punch and round more than one paper? like a whole book? thanks!**
A: 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.

**Q: which are the cutting dies provided? In inches please, thanks**
A: 1/2    1/4   3/8   5/8 Not a bad machine but is hard to get setup for a good cut.

### ⭐⭐⭐⭐⭐ Great Corner Rounder!

EXCELLENT Corner Rounder! One of the best I've seen and the price is spot-on! You can cut a large quantity of paper with this thing and it will cut plastic, magnetic sign material, banner material, and thin metal (aluminum).

### ⭐ Poorly manufactured
*by E***T on February 4, 2014*

Not a single flat surface on the whole machine. Cutting surface not even/ground by hand. Enamel in photo replaced with thin coat of black paint. Steel on steel bearing surfaces on slide/no bushings or bearings.
