TD-1200 3:1 Wire Binder, 12-Sheet Punch, 120-Sheet Capacity | 3:1 pitch with 34 square holes for A4 sheets, adjustable 3, 5, and 7 mm margins, and a built-in wire closer.

I was searching for a device that would be able to punch several different sizes of paper and the hole size that would allow me to use many different types of clips or combs. This machine delivered. Very easy to use and very well built. Highly recommend.

I like it for the spiral binding, but haven't mastered how to use it for the double loop coils. Can't get them to bend in the middle without doing it manually (one by one by hand). Great for the punching of the holes and allowing for spiral binding though.

I really, really like this binder. Just was I needed for my small business!

As a homeschool mom who traditionally pieced together a lot of materials from a lot of sources, I quickly learned the value of being able to bind things nicely all by myself. It gets expensive to go do it professionally. I'm done homeschooling now, but I still love to be able to bind up my own planners, Bible studies, recipe books, or whatever. This binding machine is fantastic. It goes together pretty easily. There is perforated cardboard included that you are to use to punch things a few times to clear out any oil in the mechanism. There definitely was some. This works really smoothly. Very easy to punch. This includes three different styles of binders. I was a little confused in looking at the directions as to just how you were supposed to crimp the two crimping types of binders. Once I figured out that you set that in the top and pull down the punching handle again, it was pretty simple. Absolutely fantastic.

Super functional and easy to use binding machine. This is the perfect size and not taking up too much space. Excellent storage capacity and an Excellent value.
