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 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. 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. Specialized hand-operated tape punches were used to perform small edits and repairs on punched paper tapes used for data entry into teletypes or early computers. Torn or damaged tapes were sometimes aligned with specialized jigs, spliced with special adhesive tape, and the holes encoding data were manually restored using such punches. The ASCII character code included a special DELETE or DEL character defined as all holes punched out (code 7F), allowing an erroneous character to be canceled by punching extra holes.Whether you’re looking for a single hole punch or device which will work for several sheets simultaneously, we have a wide selection of hole punch equipment and accessories.

There are other binding techniques which use hole punching. Coil binding uses a spring-like coil, threaded into the punched holes. Comb binding uses a plastic strip with "fingers" that clip into the punched holes. Both use their own types of specialized hole punches. Comb binding typically punches 19 or 23 rectangular holes (for letter and A4 paper sizes, respectively). Convenient and uncomplicated online shopping in no time at all! Our wide range offers you a huge selection of great brand products at unbeatable prices. 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. As punched tape technology became obsolescent in the 1980s, the manual tape repair tools became rare.

Alternatively, sort sheets and thread together for use as a working document, all with the help of a paper punch.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. 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.

Concerns have risen about the lifespan of the hole punch as most paper documents are now online, making the use of it irrelevant.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. 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] Appleton Standard Layout" (PDF). Archived from the original (PDF) on 2013-11-26 .

The essential parts of a hole punch are the handle, the punch head, and the die. The punch head is typically a cylinder, with a flat end called the face. The die is a flat plate, with a hole matching the head. The head can move, while the die is fixed in place. Both head and die are usually made of a hard metal, with precise tolerances. One or more sheets of paper are inserted between the head and the die, with the flat face of the head parallel to the surface of the sheets. Moving the handle pushes the head straight through the sheets of paper. The hard edge of the punch vs the die cuts a hole in the paper, pushing the cut piece out the bottom of the die. The cut-out bit of paper scrap is called a chad. 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. 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.

For the US letter paper size ( 8 + 1⁄ 2 by 11 inches, 220 by 280mm), a three-hole standard is widely used. The holes are positioned symmetrically, with the centers 4 + 1⁄ 4 inches (108mm) apart. It requires paper formats that are at least 9 + 1⁄ 2 inches (241mm) high. This article needs additional citations for verification.
