Akiles DuoMac C-421 Wire and Coil Binding Machine

The Akiles DuoMac 421 can bind documents with both 4:1 pitch plastic coil and 2:1 pitch twin loop wire. The unique design of the 421 includes a the ability to punch both a 4:1 pitch hole pattern for spiral coil binding and a 2:1 pitch hole pattern for twin loop wire binding 5/8" up to 1 1/4". This gives you the ability to choose the look and feel of your bound books and presentations. Four to One pitch coil (4 holes per inch) is the standard pitch of spiral coil used for binding presentations, proposals and books. Normally, you would have to use two different binding machines to do the same tasks as the 2-in-1 DuoMac 421.
