Punching vs. Drilling — Holes And How We Make Them

Some machines can only punch near the spine; some can punch anywhere on the sheet. This comes in handy when punching windows, slots, wraparound covers, etc. There is more to punching than double-loop wire and plastic coil patterns. Make sure that your machine has jam-up detectors or that it can reverse if you have a horriffic jam-up to save time and stock.
