the Tamerica Duracoil is a pretty impressive machine

Color coils offer an aesthetically
pleasing way to bind your important documents. However, the actually
binding process can be tricky, which is why you need a machine to help
you out. One option is the Tamerica Duracoil CI Inserter. This device
makes it easy to bind your documents but it does have a couple of
things you should keep in mind before purchasing it. Here are all of
the details about this device so you can determine if you need it to
finish off your documents.

The details:

• The
  Duracoil is a spiral coil inserter only. It will not punch the pages of
  your document nor will it crimp the ends of your coils. It can be used
  on its own or in conjunction with other binding devices.
• This
  machine can handle coils that have diameters of 25 millimeters or less.
  A 25 mm spine can bind a document containing up to 220 pages. This
  isn't the best binding capacity because there are larger coils that can
  bind together as many as 440 sheets.
• If you're not sure what
  coil you should use for a particular document, the Duracoil has a spine
  selector guide that can help you out. When you use it, you'll not only
  be able to select the right spine, you'll save yourself some time
  because you won't have to re-bind the document at a later date.
• One
  of the best things about this device is that its motor was designed to
  handle continuous use. You'll be able to use the machine all day and be
  confident that it won't overheat.
• This device ensures a
  smooth binding experience because its roller is grooved, allowing for
  continuous coil insertion. This roller has been patented because it's
  so innovative.
• The Duracoil is a very well-built device
  that features all-metal construction. It would be ideal for heavy-duty
  use in copy shops, offices, schools, and other environments so long as
  the binding capacity is acceptable. Also, this device isn't that large,
  so you won't need to worry about it taking up too much space.
• Finally, the Duracoil is backed by a one-year warranty so you'll be covered in case you encounter any problems.

Conclusion:

Overall, the Tamerica Duracoil is a pretty impressive machine, its
binding capacity notwithstanding. It's incredibly well-constructed so
it can be used for years without needing to be replaced. That the motor
is unlikely to overheat is a great thing too. The roller system is
fantastic and really helps make the binding process easier and faster
so you can focus your attention on more pressing matters. You'll just
need to be sure that the binding capacity is something you can live
with. A 220-page capacity isn't bad, but considering color coils can be
used to bind up to 440 sheets, it's a bit of a disappointment.
Nonetheless, if the 220-page binding capacity is suitable for your
needs, the Duracoil would be a great choice, especially if you want an
incredibly durable device that can withstand a lot of use.
