What is the Difference Between the Akiles Coilmac Plus Machines and the Non Plus Versions?

Updated on Dec 26, 2025

Akiles Coilmac spiral binding machines are some of the highest quality pieces of coil binding equipment on the market today. However, one of the primary questions that we get here at MyBinding is concerning the difference between the regular models and the plus versions. This video will help you understand what the differences are so that you can decide for yourself whether it is worth spending a little bit more money for the plus version. However, in a nutshell the primary differences are that the plus versions offer oval hole punching, fully disengageable pins and 44 holes instead of 43. The oval holes make it easier to insert the coils onto your documents and the fully disengageable pins make it easier to punch custom sized sheets and special documents. These features are often worth the small premium that is charged between the models. Watch the video and decide for yourself whether it is worth it to upgrade.


Here is the audio transcript for this video:

Welcome to MyBinding video. This video is made to help you understand the difference between the regular and the plus models of the CoilMac line. Akiles makes four CoilMac machines, the M, ER, ECI, and EPI, and their corresponding Plus versions. Side by side, each model looks to be very similar. They have the same features but have two major differences.

The first, the shape of the punch. On the regular models, that is the M, ER, ECI, and EPI, the holes that are punched are round and they are 4mm in diameter, punching four holes for every one inch. On all four of the corresponding Plus models, the holes that are punched are oval-shaped, 4mm wide and 5mm tall, also with a 4:1 pitch. The oval holes are more popular because they tend to work better with thicker documents and lay out more naturally along an 11-inch length. Also with oval holes, the beginning threading that you must do by hand is much easier.

The second major difference is the disengaging punch dies. All Plus models have fully disengageable punch pins. This allows for a clean punch with virtually any document length and without fear of half holes punched. While all of the regular models have only five disengageable pins, which allows you to work with the most standard sized of documents.

Those are the two major differences. Now you're on your way to choosing the right machine. For more comparisons, demos, reviews, and how to's, check out MyBinding.com.
