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

I’ve been using it for a few years now and it works like a charm. You can’t punch more than 20 pages at a time, so it really depends on how much you need to use it and how patient you are. For my needs, though, it’s perfect. The top mechanism makes binding easy, you don’t have to manually twist it yourself. There’s also an adjustable guide that helps you align the paper properly, so it always punches in the exact same spot. That way, even if I have more than 20 pages and need to punch them in batches, everything lines up perfectly when I bind it later.

What an amazing machine! Quality item, easy to ease, seems durable (I've only used it for 85 booklets, each with over 40 pages, thus far). The bonus is the electric coil threader... it is very quiet, works nearly every time, though sometimes a coil will go through but miss a couple pages... easy to unwind and correct. The whole experience in using this machine is excellent. Much cheaper than paying for this service... the machine has already paid for itself!

works great!

Set up was super easy and I was able to start making spiraled books within 10 minutes. This also was a nice compact size and I’m excited for the automatic coiler.

After writing my book and checking the prices to self publish it, I decided to make an investment in a laser printer and the tools to coil and head bind myself. This was the 2nd unit I tried, as the previous from another supplier arrived broken. Per the manual to set up, easy peasy. And the 20 page guideline per 20lb paper is pretty accurate, I was using 24lb matte coated paper and dropped down to 16 to 18 pages with no issues. The Auto Coiler onto is a bit tricky and I will say, my book is 413 pages and could not be run on the coiler, its just too thick. And that isn't the machine issue, its the book. I plan on making the Teaching Outline in a coil book format as well and I am sure the coiler will work for that size. Great gadget for the office, light weight, easy to clean out tray for the punched paper and handled the vinyl covers with ease.
