These hand coil crimpers, also known as coil crimping pliers, cut and crimp the coil once it's been inserted into your document to prevent the coil from spinning out of the book. Simply insert the pliers into the section of coil needing to be crimped with the red dot facing up, close them shut on either side of the book and your coil document is bound. This is an excellent product for companies looking to save some money in their coil binding production, doing the same job as an electric crimper with relatively little effort. Call us toll free at 855-880-7500 with any questions on how to use the coil crimping pliers.Ā
