Black Spiral Binding Coils

Buy black spiral binding coils online at Binding101 for the best pricing and fastest shipping. This popular colored binder spine is stocked in the full range of sizes 6mm to 50mm so you can bind documents from just a few pages to huge 440 sheet books. We stock a wide variety of pitch patterns, lengths, and sizes to choose from.

 

Coil Binding Pitch

The pitch of a coil binding spine varies depending on your machine; the most common is a 4:1 pitch with 4 holes for every inch of length. 5:1, 3:1, 2.5:1. and 2.231 mm are also available for more specialized applications. "pitch" actually means the holes per inch. So the most popular 4:1 (read aloud as "four to one") has four holes for every one inch of length.

 

Coil Binder Spine Length

The most common length of pre-cut coil binding spirals is 12 inches. This is the best size for a standard letter size 11-inch document. The extra inch of length leaves one half of an inch on each side of your book, which allows you the space needed to cut and crimp the edges of the coil. There are also 36-inch coils available, which led you to choose the length you want for your various or more unique book sheet sizes.

 

Coil Binding Capacity

All capacities listed are approximations calculated based on standard 20 lb. copy paper. They are based on sheets of paper, not pages (every sheet has a front and a back page).

  • 6mm (1/4") = 35 Sheets
  • 7mm (9/32") = 47 Sheets
  • 8mm (5/16") = 60 Sheets
  • 9mm (23/64") = 70 Sheets
  • 10mm (3/8") = 80 Sheets
  • 11mm (7/16") = 90 Sheets
  • 12mm (1/2") = 100 Sheets
  • 13mm (17/32") = 110 Sheets
  • 14mm (9/16") = 120 Sheets
  • 15mm (19/32") = 130 Sheets
  • 16mm (5/8") = 140 Sheets
  • 17mm (0.67") = 150 Sheets
  • 18mm (23/32") = 160 Sheets
  • 20mm (3/4") = 170 Sheets
  • 22mm (7/8") = 200 Sheets
  • 25mm (1") = 230 Sheets
  • 28mm (1-1/8") = 250 Sheets
  • 30mm (1-3/16") = 270 Sheets
  • 32mm (1-1/4") = 290 Sheets
  • 35mm (1-3/8") = 300 Sheets
  • 38mm (1-1/2") = 320 Sheets
  • 40mm (1-5/8") = 350 Sheets
  • 45mm (1-3/4") = 390 Sheets
  • 50mm (2") = 440 Sheets

 

One of the main advantages to plastic coil binding is that it allows document pages to open 360 degrees and lay completely flat. With plastic spiral binding coils, you can efficiently and expertly produce documents that are ready to mail and leave a lasting impression.

Video Transcript
Plastic coil binding, also called Spiral Binding, is an incredibly durable and flexible way to bind books, making it one of the most popular document binding solutions on the market today. A binding coil looks like a phone cord, with a continuous plastic spine that spins around into many loops. The coils are spun into several closely spaced holes that are either round or oval shaped, punched along the edge of a book.

Plastic coil binding, also called Spiral Binding, is an incredibly durable and flexible way to bind books, making it one of the most popular document binding solutions on the market today. A binding coil looks like a phone cord, with a continuous plastic spine that spins around into many loops. The coils are spun into several closely spaced holes that are either round or oval shaped, punched along the edge of a book.


They are made of a very flexible plastic material that can bend in all directions, and still retain its original shape. This makes them very durable, and able to withstand heavy handling. Binding coils come in a large variety of colors and sizes to bind books up to about 440 sheets, or a 1-3/4” thick stack.


To bind with spiral binding, you will need a coil binding machine, the coils themselves, and a pair of cutter crimper pliers. You can also use an electric coil inserter for higher volumes to drastically increase the inserting speed. Just punch your pages, roll the coil through the holes, and then crimp in the ends. Once bound, your books can lay completely flat and pages can turn a full 360°.
