Hanging calendars, spiral notebooks, planners and binders all need neat, aligned holes. Punching sheet by sheet is slow and the holes often end up misaligned. A paper drilling machine drills the whole stack in one pass.

Jobs that need a drilling machine

  • Desk and wall calendars.
  • Notebooks, planners and modules with ring or spiral binding.
  • Documents for binders, often ordered by schools, universities and offices.

50L Paper Drilling Machine specifications

  • 50 mm drilling capacity, meaning a stack that thick can be drilled at once.
  • Paper size up to 460 × 290 mm.
  • Hole margin adjustable from 5 to 45 mm from the edge.
  • Drill bits from 3 to 10 mm, matched to the binding type.
  • 27 kg and 500 × 500 × 480 mm, fits on a workbench.

Tips for neat holes

  • Jog the stack even before drilling so every sheet lines up.
  • Do not exceed the 50 mm capacity in a single pass.
  • Choose the bit size to match the spiral wire or ring you will use.
  • If holes start to look fuzzy, check the condition of the drill bit.

How it differs from a perforating machine

A drilling machine makes round holes for ring or spiral binding, while a perforating machine makes tear lines. The comparison is in creasing, perforating and grooving.

General drilling steps

  • Set the hole margin (5–45 mm from the edge) to suit the design.
  • Fit a drill bit of the right size, between 3 and 10 mm.
  • Stack and jog the sheets, 50 mm at most.
  • Drill one stack, then check the hole position and cleanliness on the first and last sheets.

The exact sequence and operation follow the machine's instructions.

Frequently asked questions

Which drill bit size should I choose?

Choose within the 3–10 mm range that matches the spiral wire or ring you will use. Check the spiral size before drilling.

Can A3 paper be drilled?

The maximum paper size is 460 × 290 mm. A4 (210 × 297 mm) fits, while A3 (297 × 420 mm) slightly exceeds the 290 mm side.

How many sheets can be drilled at once?

Capacity is stated as stack thickness, which is 50 mm. The number of sheets depends on the paper weight.
