Three different international-standard two-hole punches. 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).
To bind a document, the user first punches holes in the paper with a specialized hole punch. Pages must be punched a few at a time with most of these machines. If hard covers are desired, they must be punched as well. In bulk applications, a paper drilling machine may be used. Then the user chooses a spine size that will match the document.
Die and punch shapes affect the force during the punching process. The punch force increases during the process as the entire thickness of the material is sheared at once. A beveled punch helps in the shearing of thicker materials by reducing the force at the beginning of the stroke. However, beveling a punch will distort the shape because of ...
Paper drill bits are available for different hole sizes and in different coating qualities. Unlike hole punching, where only one or a few sheets may be processed, a large number of sheets can be processed with a paper-drilling machine. Depending on the type of paper drill, either the paper drill bits are lowered into the pile or the table is ...
The tape punch, rather than punching out the usual round holes, would instead punch little U-shaped cuts in the paper, so that no chad would be produced; the "hole" was still filled with a little paper trap-door. By not fully punching out the hole, the printing on the paper remained intact and legible.
The distance from the punched holes to the nearest edge of the paper is less critical, since small differences do not affect the compatibility of paper and binder. Typical distance from the paper edge to the center of the hole is 0.5 inches (13 mm), and typical diameter of the hole ranges from 0.25 inches (6.4 mm) to 0.31 inches (7.9 mm) in ...
