Punching vs. Drilling — Holes And How We Make Them

There are in-line punching machines for punching in-line with saddle binders, folders or bookletmakers. These are not to be confused with the attachments that fit into three-knife trimmers, which can take a long time to set up and can only punch very thin booklets. In-line punches can roll up to any compatible machine, set up quickly and be fed with an on-demand basis. Some of these machines can punch booklets up to 1⁄4˝ thick.
