Well-made product, sturdy construction; absolutely no instructions of any kind included. I had to get online and find a video to watch to show me how to use it. These are large enough, that I sometimes had a hard time crimping my 1/4" coils. Once I figured out exactly where to place everything, it did fine most of the time. I would say, with anything larger than the 1/4" coil, you won't have any trouble at all. They really do seem to be a nice, quality product.

When I first got these I kept doing it wrong and cutting off the coil instead of bending it over. I had to watch the video a couple of times but now they work really well. Turns out I was using them upside down.

I ordered a spiral binder, spirals, and a crimper from MyBinding. It was one of the most affordable deals I could find, and there were no issues with the shipping or tracking of the order. I also called the customer service line and they were very polite and accomodating.

The Coil Hand Crimpers/Crimping Pliers which I purchased are easy to use to finish the ends of coils on the many books that I bind. A professional looking finish is easily attained by cutting the coil and finishing the ends with a neat crimp. The crimp is longer than with some instruments preventing the coil from unwinding.

These crimping pliers work OK...You do have to put a little muscle into it and there seems to be a bit of a technique to getting them to crimp the end well (I usually get a decent crimp but my 12 year old has some trouble.)
Spiral Coil Hand Crimpers Product Review
Spiral coil crimping pliers are used to finish binding documents with spiral coil. They cut off the excess coil and bend the ends over in a single motion, helping to ensure that the spirals don’t spin back off the book. Usually, spiral coils are purchased longer than the edge of the document you are binding. Most spiral coils are purchased in lengths that are approximately 1″ longer than your finished binding edge, allowing for the crimping process. Special crimping pliers makes the finishing process much easier, preventing you from having cut off the coil and then manually bend the end over so that it will stay secure.
These pliers are marked with a red dot on one side, helping you align the pliers during the crimping process. It is also important to note that the red dot should always face the ceiling, and keep the spine of the book facing toward you when you are crimping coil.
Spiral Coil And Crimpers also offer a standard throw length, or length of the piece of coil that is bent over, which is ideal for 4:1 pitch and 5:1 pitch coil – the two most common sizes. In addition, the plastic coated handles of these pliers make them easy to hold and easy to use.
Although the throw length of the pliers is ideal for standard 4:1 pitch and 5:1 pitch binding., trying to bind documents with 4:1 pitch oversize oval holes, 3:1 pitch holes or 2.5:1 pitch holes will be difficult. With larger holes the throw length may not be long enough. This could allow the spiral coil to spin off the book. For these applications, premium oversize oval hole crimping pliers are suggested.
The pliers must be squeezed hard enough to bend the end of the coil over but not so hard that you cut the end off. This can take a bit of finesse, and those who work with high volumes sometimes find the coil crimping process tedious and labor intensive. In this case, there are several automated crimping tools available on the market, but they can range in price from a few thousand to tens of thousands of dollars and often require significant amounts of setup time.
Some new coil binding machines now include a small crimping tool on the machine itself and are easy to use, but are also very expensive. They may be a good alternative, however, for those who dislike crimping documents with these pliers.
Anyone who uses a coil binder should have a pair of coil crimping pliers, so if your machine doesn’t’ come with a pair, it is highly-recommended that you include one in your order. Although high-volume users may consider other crimping options, it is best to consult with a document finishing specialist before deciding which option will work best for your application. And don’t forget – customers who use non standard pitches or oversize oval hole pattern should consider a pair of pliers with a longer throw for the best effect.
