The Akiles CoilMac-EPI+ coil binding machine is a heavy-duty, all-electric binding machine capable of handling commercial-volume workloads. The CoilMac-EPI+ is equipped with a powerful electric punch that is capable of up to 25 sheets at once (based on 20 lb. paper) that uses Akiles' exclusive "Precision Guiding System" to ensure a clean, precise punch every time. The CoilMac-EPI+ also features innovative 4mm x 5mm oval punching dies, which make inserting coils and turning pages faster, easier, and more smooth than with traditional round dies. This model has 54 fully-disengaging dies as well as an open punching throat and continuous punching guide, which give it the ability to punch a wide variety of document sizes. The CoilMac-EPI+ has a full-length electric coil inserter that is designed for heavy-duty use, with an industrial-grade roller motor and foot pedal operation. The double-roller inserter is capable of inserting coils up to 7/8" in diameter (coils up to 2" in diameter can be inserted manually). The CoilMac-EPI+ is backed by a one-year manufacturer's warranty, and its durable, all-metal construction will provide you with years of trouble-free use. Free premium coil crimping tool is included. The CoilMac-EPI+ is compatible with all standard 4:1 pitch binding coils, including GBC Color Coils.
