Combine two of the most popular document binding solutions into one machine with the Akiles DuoMac 431. This binding machine punches two patterns to handle both plastic spiral coil binding and twin loop wire binding. The coil punch pattern is a standard 4:1 pitch with round holes (0.250), and the wire punch pattern is a 3:1 pitch with square holes. This means that you can punch for the full range of spiral binders up to 50mm (or about 440 sheets*) and with 3:1 wire-o binders up to 9/16" (or about 120 sheets*). With the DuoMac 431 there is no need to spend money on two machines that take up a bunch of your tablespace. Instead, you can punch and bind for low to medium volumes of books from one fairly compact machine.

Spend less time switching out dies while saving money on equipment investments when you choose the DuoMac 431 from Akiles and Binding101. This innovative machine is ideal for low to mid-volume users who want the ability to punch and bind for both wire-o and spiral coil, without the budget to pay for two separate machines or a heavy-duty interchangeable die machine. Instead, the DuoMac accomplishes the two most popular documentation binding styles from one fairly compact machine.

With two independent punch openings (punching throats), you can quickly create a wire book and then go straight to a coil book without any setting adjustments. Independent punching handles gives you complete control of your machine, and depth margin adjustments let you choose how deep you want the holes placed on your pages. The 14" edge has an open-end, which allows for up to 28" binding lengths if you flip your pages and punch a second time. Plus, disengageable punching [pins let you customize the top and bottom edge margin for perfectly centered holes on any size document. This wire and coil binding machine is a perfect fit for many kinds of offices or businesses.
