A hole punch is a handheld or desk-mounted tool used to create holes in paper, cardstock, or other materials. It consists of a metal or plastic frame with a rotating or spring-loaded plunger that pushes a sharp blade through the material. Hole punches come in a variety of sizes, from small ones that make one-hole punches to large ones that can make multiple holes at once. They are often used in offices and schools to punch holes in papers for filing or binding.
