The coil bookbinding or spiral binding is a popular type of book or leaf binding, which is particularly popular for presentations. With a metal wire, a kind of double spiral is formed, which runs through the previously perforated paper leaves. Sometimes a kind of plastic comb is used. It is a cost-effective and stable combination. It is used a lot in notebooks and manuals of intense but brief use. The most common way to make holes is with a punching machine, which performs all the holes that will go on the same page, all at once. These drills have standard measures for spacing holes, making them circular, others making them square or rectangular, and each type of hole has a different spiral. Depending on book or calendar thickness, different spiral diameters are used. One differentiates between plastic spirals (made of hard PVC) and wire spirals (coated with a thin nylon coat). These are largely used in offices, colleges, and workplaces. Because of the large usage, these coil book bindings are extensively available in the market in different thickness and sizes.
