A & W Office Supplies 3-Hole Paper Punch-Black

Product Information

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. Konica-Minolta specifies that the holes should be 11 ±1mm from the edge of the paper [6] for European 4-hole arrangements, contrary to ISO838. The principles of the hole punch have hardly changed since the original invention, and this piece of equipment is still widely used in offices and schools today. Hole Punch Sizes 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).

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.

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. hole system exists. It is still in use today, but is not as common as the 3-hole standard. The four holes are positioned symmetrically with centers 3 + 1⁄ 2 inches (89mm) apart. The four binding positions provide more support for the longer 14-inch side of legal paper.

Single-hole punches are often used to punch holes through old playing cards at casinos, marking them as "used" or "canceled". This helps cut down on cheating by eliminating any cards that may have been tainted by players. Rexel P240 Punch 2-Hole Heavy-duty with Nameplate Capacity 40x 80gsm Silver and Blue 2100749 800287...

Black Heavy Duty Metal Hole Punch 40 Sheet

This is a different measurement of 4 hole punch which is designed to be used with legal-sized paper. It is much less common in the US than the 3 hole punch, though it is still in use. This size of hole punch is set by the International Organization for Standardization and is therefore accepted as the standard size of hole punch across the world. When using this hole punch on paper, those papers will be compatible to be bound by a two-ring holder.

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. 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. We have a huge range that includes standard 2-hole punches, single hole punches, 4-hole punches and high capacity heavy duty punches. The most common style is a 2-hole metal with plastic base. These start with a punch capacity of 10 sheets of 80gsm paper and go up to around 30 sheets. Our four hole punches are designed for punching papers to go in a 4 ring binder.

This is a hole punch that is widely used in the US for letter-sized paper and is compatible with standard 3 ring binders designed to hold letter-sized paper. Most people are familiar with a hole punch, which also goes by the names of the hole puncher, and paper puncher. This is a piece of office or stationary equipment which is used to punch holes in paper, typically for the means of binding them together in a folder. In this article, we’ll discover the standard hole punch sizes.

Anniversary of the Hole Puncher, Drawing by Gerben Steenks, 14 November 2017, archived from the original on 2021-08-20 , retrieved 14 November 2017 {{ citation}}: CS1 maint: others ( link) 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.Single-hole punches are widely used in the British Civil Service where papers are punched with a single hole in the upper left, and secured using a treasury tag. 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. 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.
