Using the AP2-Ultra you can punch an incredible volume of paper in no time at all. Each of the die sets listed below allows you to produce a different hole pattern using your AP2. The most popular die sets are probably coil, combs, wire and 3-hole. However, we carry all of the different die set options for this machine. Changing die sets on the AP2 isn't very difficult (it takes us a few minutes). In most applications die sets will last for years. However, eventually the dies become dull (and the punched holes look rough) in which case you will most likely need a replacement die. Check out the options below and if you need help choosing the right one for your application please feel free to contact us.
