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

Product Information

A hole punch, also known as hole puncher, or paper puncher, is an office tool that is used to create holes in sheets of paper, often for the purpose of collecting the sheets in a binder or folder (such collected sheets are called loose leaves). A hole punch can also refer to similar tools for other materials, such as leather, cloth, or plastic or metal sheets. A single-hole punch makes a single hole per activation, usually at an arbitrary position (i.e., without alignment guides). The United States and a few other countries use non-ISO paper standards, defined in ANSI/ASME Y14.1 and other intra-nation standards. Unlike ISO838, there appears to be no well-established official specification for ANSI paper hole patterns, and instead they are de facto standards, established by custom and tradition. 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.

In Sweden, a four-hole national standard [7] is almost exclusively used. 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.

Made of metal, you can easily perforate up to 5 sheets of 80 gsm paper and this hole punch hasa confetti reservoir. The official name of this four-hole system is triohålning, since it was adapted to the "Trio binder" which was awarded Swedish patent in 1890. The binder's inventor, Andreas Tengwall, supposedly named it after a consortium consisting of himself and two companions, i.e. a trio. [ citation needed] The binder can be opened at any place while holding the papers in place, as the inner holes have guide pins from one side, the outer holes have pins from the other side.

A variety of hole patterns are in use for ring bindings. In much of the world, two-hole and four-hole punches consistent with ISO 838 are the norm. In the US, the three-hole punch is most common. See §Standards. Concerns have risen about the lifespan of the hole punch as most paper documents are now online, making the use of it irrelevant. A hole punch does not necessarily make round or square holes in a sheet of paper; instead, it may create certain shapes along the edge of the sheet. This is seen in discbound notebook systems, where loose leaves are bound together using plastic discs. For more information on loose leaf systems, see Loose leaf. There are hole punches which punch patterns of multiple holes at once, typically for binding multiple sheets together (see §Applications). Such punches generally feature two paper guides for alignment. One guide will be along the side of the paper to be punched, and sets the distance of the holes from the edge of the paper (the margin or gutter). The other guide will be on a perpendicular side, and aligns the holes between the top and bottom of the sheet. One or both guides may be adjustable. Another standard also occasionally used in the US is a "filebinder" system. Its two holes are positioned symmetrically, with the centers 2 + 3⁄ 4 inches (70mm) apart.Hole punches are available in standard two-hole models that are designed for ring binders and lever arch files, single hole punches to give you maximum flexibility, and 4 punch holes for unusual gauges of binder.

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] The most common use for multi-hole punched paper is with a ring binder. A book-like cover is fitted with retaining rings matching the pattern of the punched holes. The rings may be split open, paper sheets threaded onto them, and then the rings closed again.
