Hole punch

Common card · No. 444336

A hole punch, also known as a hole puncher or paper puncher, is an office tool used on stationery. Hole punchers are used to create holes in sheets of paper, often for the purpose of collecting the sheets in a binder or folder. They may be handheld, for single holes, larger or table-bound (for two to four holes), or mechanized full-sized machines. Holes are either punched (for single pages of paper to smaller stacks of paper) or bored (for very large stacks of paper, often done by an electrical machine at a professional stationer or printshop). Punched pages of paper (usually referring to pre-punched pages of paper) are called loose leaf. A hole punch can also refer to similar tools for other materials, such as leather, cloth, or sheets of plastic or metal.
