The more you can punch at onc

  •  An appropriate punching length and disengageable dies. An important consideration when choosing your device is punching length.

Unless you plan on working with larger documents, this length should be just fine. If you do want to create larger books (such as ones that are 8.5" x 14" - legal size), the device you choose needs to have either a longer punching length or an open throat. It also needs to be equipped with disengageable dies so you can punch the right number of holes.   A sufficient punching capacity. This refers to how much paper the machine can punch at one time.
