The Akiles CoilMac-M+ coil binding machine pairs efficiency with affordability, making it an excellent choice for any small office. The CoilMac-M+ has a heavy-duty, manual punching mechanism that is capable of punching up to 20 sheets at once (based on 20 lb. paper), with a 13" maximum punching length and open throat to accommodate longer sheet sizes. The CoilMac-M+ features user-friendly oval punching dies, which make inserting coils faster and easier than ever before. This model also has 54 fully-disengaging dies, an adjustable depth margin control, and a sliding side margin guide to help ensure that every binding project regardless of document size has a polished, professional look. The CoilMac-M+ makes manual coil inserting easy, with its unique "EZ Inserting Table" that can be detached from the punching mechanism to create a stand-alone binding workstation. This machine is built to last, featuring all-metal construction and a one-year manufacturer's warranty. The CoilMac-M+ works with all standard 4:1 pitch binding coils, including GBC Color Coils.
