TruBind 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.

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: Packaging One 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. Documentation Thank 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 Quality The 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. Features As 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 Use The 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 Thoughts Plastic 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.

For the past 25 or so years I have been using a comb-binding machine for creating my own music books, or for cutting music books apart and rebinding so they will actually stay open on the music stand (don't music publishers ever think their customers actually want to use the music books they buy?). Until now -- coil binding is so much better than comb-binding! When the teeth of a comb binding pull out (as they inevitably do) and get bent, they can be a real bother to put back and I often simply need to put a new comb on the book. Coil binding eliminates that problem and it is so much easier to pull a coil out of a book if something needs to be added or removed or changed. This TruBind TB-S20 machine is easy to use, takes up only a tiny bit larger space on the shelf or table, and best of all, it is affordable! The coils are a bit more expensive than combs, but with the large variety of sizes and colors, they can be used to great effect and they won't break or need replacing the way that combs do. The one thing that this machine lacks is any instruction on how to use the pliers to cut and crimp the ends of the coils once they are in place on the book. HOLD THE PLIERS SO THAT THE RED DOT IS ON TOP AND IS FACING TOWARD THE BOOK. INSERT THE COIL AND SQUEEZE THE PLIERS SHUT AND THE EXCESS COIL IS CUT OFF AND THE REMAINING END IS CRIMPED SO THAT AS THE COIL TURNS IT WON'T COME OUT OF THE BOOK. If you need to remove the coil simply use a small pair of needle-nose pliers to straighten the end of the coil and then twist it out of the book. There's no need to buy the more expensive coil-binding machines which have electric coil inserters. It is so easy to simply twist the coil through the book by hand and this machine can be used anywhere -- it doesn't need any electricity. It makes me wonder why I didn't buy one years ago!

Works very well for my small office needs.

Excelente maquina, de buena calidad. Puedo hacer mis engargolados y sin complicaciones, fácil de manejar y todo lo que necesito lo adquiero por Amazón y no ha habido problemas.

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.

I bought this as I had a lot of material to bind, and would usually use Staples or an outside print shop. WIth COVID, I wanted something I could use at home. This punch (with spiral coils you buy separately) really served the purpose. In fact, I think the cost of this machine (covers and coils) turned out to be cheaper than having it bound outside. The machine is very heavy duty and easy to use.

This is an amazing little machine! Perfect for anyone looking for a coil binding machine without the massive price tag. I do usually only punch one page at a time, as I use a very thick paper for my binding projects, but it can easily do more than that when punching standard paper. I love this machine and am very happy with my purchase.

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.
