Rapesco PF25A001 Single Hole Punch Model 25, 10 Sheet Capacity, Silver

Product Information

Concerns have risen about the lifespan of the hole punch as most paper documents are now online, making the use of it irrelevant. As punched tape technology became obsolescent in the 1980s, the manual tape repair tools became rare. Single-hole punches can also be used for binding, with a single loose binding ring, although this is much less common than with ring binders. A related office tool is the eyelet punch. This is a single-hole punch which also crimps a metal fastening loop around the hole, similar to a rivet. It is used to permanently secure a few sheets of paper together.

The centers of the holes are 21mm, 70mm and 21mm apart, 10.5 ±0.5mm from the edge of the paper. The guides help keep the paper in a straight line. a b "PK-520 Punch Kit Installation Manual". Konica Minolta. p.E-4. A3ET-9550-01 . Retrieved 2021-12-22. The diameter of the holes varies between manufacturers, with typical values being 1⁄ 4 to 5⁄ 16 inch (6 to 8mm). The 5⁄ 16 value is most commonly used, as it allows for looser tolerances in both ring binder and paper punching. The distance to the paper edge also varies, with 1⁄ 2 inch (13mm) hole-center-to-edge being typical. Konica-Minolta specifies 9.5 ±1mm [6] for both two and three-hole variants in North America.

International Standard ISO838 specifies two holes, with centers 80 ±0.5mm apart, and located 12 ±1mm from the nearest edge of the paper, and with the pair of holes positioned symmetrically along that edge. Each hole is to have a diameter of 6 ±0.5mm. Any paper format that is at least 100mm high can be filed using this system (e.g., ISO A7 and larger). A printed document with a margin of 20–25mm will accommodate ISO838 filing holes.A four-hole extension to ISO838 is also in common use. Two holes are punched in accordance with the standard, plus two additional holes located 80mm to the outside of the standard holes. The two additional holes provide more stability in 4-ring binders, while still allowing 4-hole paper to fit 2-ring binders. This extension is sometimes referred to as the "888" system, because of the three 8-cm gaps between the holes. Some 2-hole punches have an "888" marking on their paper guide, to assist punching all four holes into A4 paper. [5]
