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

If you are thinking about getting this for high-volume commercial use, it may not be the best choice. For home use or low to moderate volume commercial use, I don't think you can go wrong for the money. There are specific aspects of this machine that probably deserve separate attention:PackagingOne reviewer pointed out that the electric coil inserter and the silver drum underneath came damaged. While I’m sure that Amazon will make good on this, I was a little bit concerned since I have on occasion purchased marginal quality devices online without realizing it. One of the key markers of this type of inferior quality is its frequency of arriving broken. The outside box that my machine came in was pretty beat up. I think this may have been because our 4 fairly large dogs met the deliveryman in the driveway and I have a feeling he just tossed it out of the truck. Nevertheless, I found that Amazon, as usual, had done an excellent job of packing. The outer box contained cushioning material which surrounded an inner box. The machine itself was very securely packed with foam inserts. I found absolutely no damage or malfunction to the device whatsoever.DocumentationThank goodness for YouTube. The documentation with this device was practically nonexistent. It came with an 8.5 x 11 sheet of card stock which was folded in half as its full user manual. Something like what you normally would see for a “quick start guide”. All it really said was basically you put the sheets in, you punch holes and then you put the coil in. There is a small tab sticking out of the left side of the machine with no indication whatsoever as to its purpose. It actually turns out to be an adjustable guide so that you can switch from a 4 ½ mm border to a 6 ½ mm border if you want the holes a little bit further away from the edge of your sheet. There is a fuse holder in the back of the machine which is also ignored in the instructions but if your electric coil inserter seems like it’s “dead”, this is where to check the fuse. Right below the fuse is a removable tray where the little circles go that are punched out of the paper. It pulls out towards the back. This is also something that was ignored in the instructions and is not immediately obvious.Construction QualityThe housing and work bed are plastic. This is okay though because the working parts of the machine are quite heavy and appear to be quite sturdy in construction. Some of the individual punches appeared to stick slightly on retracting but I’m sure this will improve as it “wears in”. By the way, the punches are lubricated and will stain the first few sheets that you punch. If it is an important presentation, you definitely want to cycle the machine a dozen or so times with scrap paper before you use it on important work. It is rated at 20 sheets punch capacity with 20 # stock. I think this may be a bit of a stretch. I did do 20 sheets of 18 # stock successfully but I would not want to do it on a repetitive basis both for the amount of effort involved and the strain on the machine. 15 sheets at a time is probably more reasonable. I really like the full handle design on this device. Many of the machines out there have a single crank type handle on one side. I can’t imagine punching holes in 15 sheets of paper with one of those devices without having it twist from the torque.FeaturesAs mentioned above, you can adjust how far away the holes are from the edge of the paper. Any of the punches can be disengaged so that you do not have any holes overhanging the edge of your sheet. It is not necessary to disengage all of the ones you’re not using, just the last one at the edge. (The last job I had “professionally” bound at Staples completely ignored this and all of the books had holes hanging off the edges of the sheets. Did not look very professional at all.) There is a gauge printed on the front bed of the machine that you can lay your sheet on to see exactly where the holes are going to fall and which, if any, punches you need to disengage. There is also a printed guide that tells you what size coil to use depending on the number of pages you are going to bind. This is handy but it would be nice to have a feature like I saw on another machine where you simply slide the document that you want to bind into one of several slots to see how thick it is and what size coil to use. You’ll notice that the tabs which are used to disengage the punches are not straight across, they arch upward. This is because the punches do not engage simultaneously but rather the edges engage first and then work their way to the center. This is an excellent design feature. It eliminates having to exert a huge amount of force to punch all of the holes simultaneously.Ease of UseThe hole punching part is pretty straightforward. You line your pages up with the adjustable guide on the left-hand side, check to see if you need to disengage any of the punches using the circles printed on the bed and if you do, you simply pull out the silver knob of the punches that you want to disengage. Slide the pages all the way to the back, press down on both sides of the handle and you’re done. I have seen a lot of comments with regard to the electric coil inserter. Yes it does run fast. Yes it probably would be easier to use and just as effective if it was half the speed and yes it does take a little bit of practice. Unfortunately, here once again the instructions give you practically no guidance. The most important part is to manually insert the coil through the first 3 or 4 holes. Then gently press the coil against the rotating rubber drum engaging the loops of the coil in the grooves of the drum. Rest the coil on the silver roller for support. It is important that you press gently and evenly on the rubber roller. You may have to put a little bit more pressure on the left side of your document. If not, the tip of the coil has a tendency to slide under the last few pages on the top of your document instead of coming out the hole and going around again. Obviously it is also important to keep the pages of your document lined up as evenly as possible so the holes line up evenly and don’t snag the coil as it’s going through. I generally put a binder clip on each side of the document to keep the pages lined up while I am inserting the coil. If you follow these tips, you shouldn’t have any trouble after you get a little bit of experience. The machine comes with a crimping pliers that simultaneously cuts the excess coil off and crimps the end so that it doesn’t come out of the book. It is extremely easy to use, just make sure you have it oriented in the proper direction otherwise you will crimp the part that you cut off instead of the part that stays on the book.Final ThoughtsPlastic coil binding is a very cost-effective and functional way to bind loose papers semi-permanently. The cost of the coils ranges from $.13-$.25 apiece when purchased in quantity and depending on the size of the coil. It is possible to reuse them, so long as you don’t cut them too short when you put them in. If you are getting ready to throw the book away, simply snip off both crimped ends and place it against the spinning drum and it will spin the coil off in a couple of seconds. (It is actually faster and easier to remove them than to put them in) Coil binding is more functional than comb binding because it allows you to fold the book over on itself and lay it flat. It is as cheap or cheaper than using plastic report covers and the pages are much easier to read. I definitely recommend this machine for the intermittent user.

Works great. Simple to operate. Love the auto bind feature.

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!

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.

Missing items, but customer service made it right. Working with the team to address my issues. The product is great and works as expected.

I love this thing. It turns our office into an ultra low volume print shop (ultra low volume as in, like one book). We bought this for binding various documents we produce, in addition to some technical documentation that comes to us in PDF format, but have found a ton of uses for this. I've created summer writing journals for the kids, which look spectacular with clear poly cover and plastic backing. Search for presentation covers and you'll find them. I'll probably use this to make a calendar for the grandparents at the end of the year.I didn't have the oil issue some people mentioned after the first couple of cuts. Even so, what I saw was not enough to throw away the document. If you're that picky, then cut some scrap paper before starting your cuts for the document you're binding. You do need to periodically lubricate this.Things I like:- I like the fact that I can line up the holes perfectly and I can pull the little metal thingies on the front where I don't want a hole, which is useful at the edge of a book.- The hole cuts are clean- The coil inserter is cool; it does take a little practice and if you mess up, you can just flip the book over and the coil will spin right back out. It saves time.- Over the long haul it is much cheaper than sending our for printing/binding, which we used to do.- Crimpers are includedThings I didn't like:The only complaint is that the crimper is tricky to use and I can't seem to get a hang of the crimp. There are no instructions for crimping, so you just have to figure it out. There is a useful Youtube video that shows how to use the crimping tool. The coil isn't held when crimping and just pops out. I might just keep an extra pair of el cheapo pliers to do the bend/crimp if I can't figure it out. Your mileage may vary.I recommend you get a variety of sizes of coils. We started with 1/4" and 3/8", but have some 1/2" on our shopping list. The pitch is 4:1, in case you need to know. Also, if you want durable covers, you can get clear poly covers for the fronts and poly covers for the back (we use black, because black goes with everything).

Does a very decent job. Take some time and practice before you do anything that can't be reprinted. Line up the edges, try the feeder until you get the hang of it. It requires a little patience and practice. I would NOT buy the one without the auto feeder just because you don't get the disengaging dies (the holes), so you won't have the ability to adjust the holes to the length of what you punch, and may have holes falling off the edges - no biggie, but it's much cleaner if you can control that. Even if you don't like the auto feeder, it's pretty easy to self-feed the coils. I would definitely buy again, and probably won't be without one for years to come.I do a lot of printing and have a lot of instructions I want bound for quilting/machine embroidery, so this has been awesome to have on hand. I had been going to the office supply store to have them bind my things. It will probably be a while to break even on the cost, but it's really worth something to not have to go into the store (which always includes an extra trip here and there to have them fix something they did wrong). Once I received it and started using it, things were popping up that I could use it for. I bind my preschool/PreK daughters papers by year (the ones I want to keep), newsletters I want to have hand,etc.

The machine itself seems to do the job. The case is plastic but seems substantial. The problem we had is that the power supply that came with it to power the coil inserter died after plugging it into the wall. Before I had a chance to plug it into the machine, the power supply gave two loud pops and the light went out. Since our only option was to return the entire package, I found a 12V supply to use with the machine. What puzzles me is that every power supply like this one that I have ever seen has come with a label with FCC approval UL approval and country of origin with input and output values. The supply that came with the TruBind unit had no label whatsoever, not even a voltage rating. Pretty poor. The machine came with very limited instructions. Glad I found a video on youtube showing use of the coil inserter.

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.

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.

Terrific value for money. We are a reference book publishing company. This unit was purchased to bind those reference titles and research guides that we print on a demand basis. Our $5000.00 Renz binding machine is good when binding runs of hundreds of books at a time because of motorized punching. However this unit does a great job with easy hand punching, and the motorized roller for spinning the coils into the books is far better than the one on our Renz.
