7mm coil binds hold up to 35 sheets of paper
Spiral coil binding is a popular choice for binding documents, providing a professional finish and allowing pages to lay flat. The coils come in a variety of sizes, ranging from 6mm to 50mm in diameter, with the smallest size accommodating up to 30 pages and the largest holding up to 444 pages.
7mm coil binds, specifically, can hold up to 35 sheets of paper. These coils are designed for use with any 4:1 pitch spiral coil binding machine and are made from high-quality food-grade PVC plastic, offering a professional look for your documents. The 4:1 pitch is standard and compatible with binding machines that punch 4 holes per inch.
When choosing the correct coil size for your binding needs, it is recommended to measure the thickness of your stack of pages (including covers) in millimetres and select the closest size up. This ensures that your coil can accommodate all your pages and allow them to turn freely. Spiral coil binding also offers the benefit of customisability, as the coils can be cut to length with scissors according to your specific requirements.
In addition to their functionality, 7mm coil binds are available in a wide range of colours, including black, white, navy blue, royal blue, clear, green, maroon, and red. This variety allows for customisation and personalisation of your bound documents.
Overall, 7mm coil binds provide a professional and practical solution for binding documents, accommodating up to 35 sheets of paper and offering a range of colour options to suit your preferences.

Binding coils are 1 longer than the intended binding edge
Spiral coils are 1" longer than the intended binding edge length. This extra length allows for cutting and crimping at each end. The crimping process secures the coil in place, preventing it from unravelling and ensuring the stability of the bound document. Typically, a coil crimper has two components: a set of rollers and a crimper plier. The rollers help guide the coil into the desired position, and the crimper plier is used to crimp or deform the ends of the coil, effectively closing and securing the binding. This step is crucial for the overall integrity of the spiral-bound book, contributing to its professional appearance and durability.
The standard length of each coil is 12", which is intended for binding letter-size paper that is 11" long. This leaves 1/2" on each side of the page. Smaller extensions can be more difficult to handle. The most accurate way to determine the best coil size for your book is to lay all your pages on a desk (including covers and any inserts) and measure the thickness of the stack, then add 1/8" to that. Make sure you are not pressing your pages down when you measure them; just allow them to lay loose. If you press down, you may end up with a coil size that is too small to allow your pages to freely turn.
The 7mm spiral binding coils are designed for use in any 4:1 pitch spiral coil binding machine. The 4:1 pitch coil has four loops per inch of length, corresponding to four holes per inch on your paper. The coils are made from the highest quality food-grade PVC plastic and offer a quality, professional look while binding documents up to 3/16" thick. The smallest size (6mm diameter) can hold up to 30 pages, while the largest size (50mm diameter) can hold up to 444 pages.
Spiral binding is a popular document-binding method that utilizes a flexible plastic coil to bind sheets of paper together. The coil is pre-formed into a spiral shape and inserted through a series of closely spaced holes along the edge of the document. The coil is then crimped at both ends to secure the pages in place. This binding method allows for easy 360-degree page rotation and provides a professional and polished finish to documents. Spiral binding is commonly used for presentations, reports, notebooks, manuals, and other documents where the ability to lay flat and the option for full rotation are desired.

Coil binding is possible without a machine
The next step is to choose your coil bind size. You can measure the thickness of your document with a ruler and then choose the closest available coil bind size. The coil should always be longer than the pages you are binding. The standard length of each coil is 12 inches, but there are custom lengths available of up to 36 inches.
Once you have your coil, you will need to punch holes in your paper. If you are committed to binding by hand, you will need to find paper that has already been punched in the style of binding you have chosen. For a standard-size coil, you will need paper punched in a 4:1 pitch ratio, which is the most readily available option. Make sure that your hole pattern matches the coil you are using.
After you have your paper and coil ready, you can begin inserting the coil. Thread the coil into the first 4-6 holes by hand, then push the coil against the spinning inserter wheel. If you are inserting by hand, spin the coil in from either end of the sheets. You want to end up with a few loops of coil hanging out of both sides of your book.
Finally, you will need to cut or crimp the ends of the coil to keep your book securely bound. You can use coil crimpers or coil crimping pliers to do this. If you are using pliers, hold them so that the dot on the side is facing up.

While the standard coil length is 12", custom lengths of up to 36" are also available. These longer coils are intended for larger sheet sizes, as the maximum sheet size depends on the machine being used. When determining the coil size to use, it is recommended to measure the thickness of the stack of pages and covers and then select a coil size slightly larger to ensure ease of use.
