Coil Binding Machine with Electric Coil Inserter and Adjustable Side Margin | 20 Sheet Punch Capacity | Bind up to 440 Sheets | 46 Fully Disengageable Dies | 4:1 Pitch | 2-Year Warranty

This is an amazing machine. I wanted to have one for a long time and now I wonder why I waited!Essentially this machine punches holes into papers so that you can thread a spiral binding through the holes.This comes with a little clipper so you can clip the spiral rings and crimp them. You will need to buy your own spiral binders.Some things to think about:What kind of binding do you want? Comb binding is big and plastic. This one is a spiral binder. I wanted this type of binding because it seems like it would last longer than the plastic comb binding and it is easier to use when you want to flip pages back and forth.The number of holes per inch you want in your papers. It is my understanding that a 4 to 1 ratio is traditional and that is what this machine does.The number of pages you can punch with the machine you buy. This one says about 15 sheets if you are using typical typing paper/printing paper. I would say that is fairly accurate. I didn't count the number of papers, I just simply grabbed a small pile and punched. When I got too many papers I found I had to stand up and apply some pressure to get the puncher to complete the job.Do you want a special threader? This one does not have it. This machine is also a little bit cheaper than ones that have a special threader. Once i watched a few videos I felt comfortable buying this machine and saving myself some money. Essentially you punch holes in your paper, clip them together with a binder clip or two, then you twist the spiral into the little holes. Once you get it through the first hole, it twists right on. I was able to put together 5 books with over 200 pages in less than an hour while watching tv. It was that easy.i have put together my own daily journal and I plan on doing my own cookbook wiht all my saved recipes that I have stashed here and there. I have put together several spiral books for others and there are many other ideas.

I just purchased the TruBind TB-S20A, I originally was going to buy straight from the manufacture for $10 less but after shipping cost the better deal was through Amazon.I had recently bought a different brand Coil Binding Machine and it had a handle on the right side of the machine which was hard to pull and I could only punch up to 5 pages at a time. The other difference was you could not pull the pins. I returned it when i received this one.I have already bound over 5 Books of 150 double sided printed pages. It is a great machine. Easily I could punch up to 15 pages it says 20 pages. This Coil Binding Machine is well built and easy to use. The punch tray is in the back of the machine. I emptied it each time I punched as the manufacture suggested.COIL ROLLER - Works well, with the bigger books my coils did not line up or the plastic coil was not thick enough to grab hold. So I rolled them by hand. I'm hopefully going to get to use the roller at some point. I'm sure there is a learning curve as well.BINDING CRIMPER - I am a lefty. The instructions say to make sure the red dot is on top when crimping. For a Right handed person that may work. I went to You Tube and watched "How To Properly Crimp A Coil Bound Book" a great tutorial I must say. In the Tutorial it said to turn the crimper over where the red dot is on the BOTTOM if you are left handed, that worked well for me. It is still a learning curve to get it to crimp right but I got better by time I hit the third book.

This is a great binding machine for the cost. I have been using a GBC binder for decades. The wire binding is much nicer and the TruBind TB-S20A Coil Binding Machine is easy to use. The puncher works well though it would be nice if it punched more pages, though not an issue. The coil spinning wheel does go fast but it only took a minute to figure out how to easily use it. Some manual guidance for the coil is necessary, but that is to be expected. It does get the job done. I highly recommend this binding machine for those who make a few booklets or manuals daily. It might be hard to use and time consuming for mass production.
