A hole punch is a hand-held device that punches holes in paper or other materials. It is commonly used for events, customer loyalty programs, and binding paper. Different types of punches are available for different materials and designs. Buyers should choose a punch designed for their specific application.

A hole punch is a hand-held device that looks like pliers, with an internal bit featuring a rounded steel nut or tooth on a head. This nut goes through a hole in a steel tab before making contact with the opposite head. By placing the paper between the nut and the tongue, then squeezing the handles together, a perfectly formed hole is punched through the paper.

Single hole punching is commonly used in events to punch tickets so they cannot be redeemed twice. Other uses include tracking customer loyalty by issuing a card, then punching a hole each time a subsequent purchase is made. When the card is full, the customer could earn a free item or a one-time discount.

Although the typical punch provides a 0.25 inch (0.635 cm) round hole, there are other types of punches. A special punch can strike the shape of a fish, a heart, a crescent moon, a maple leaf, or one of countless other designs. Some may even say a small word, like “yes.” Using a special hole punch for customer loyalty programs discourages fraud, as a round standard is commonly available.

A two-hole punch is available for two ring binders, such as those used for repair tickets or handwritten receipts. The most popular version is the three-hole model, however, which makes it easier to use standard printer paper in three-ring notebook binders.

Some punches are made for materials other than paper. Businesses and clubs often use a slot puncher to create clip-on slots in the top of plastic ID cards or membership cards. There are also punches for fabric and leather. At the far end of the scale, a hydraulic driller will drill screw holes in different grades of steel.

People looking for a simple hand punch should make sure they get one designed for the specific application. Paper hole punchers are rated by the number of sheets of paper they can punch at once. Someone who needs to punch plastic will want a hole punch made for that purpose. The fixture a buyer chooses should be rated above the maximum thickness required. Electronic templates are also available online and at office supply stores.
