Have you ever seen a hole punch? It's a tool that people use to make holes in paper. It's like a little machine that you can put a piece of paper in. Then you push down on a handle and it makes a hole in the paper.
The hole punch has a sharp, metal part that is shaped like a circle, which is called the punch. When you push down on the handle, it pushes the punch through the paper and makes a hole.
Sometimes people use hole punches to put paper in a binder or folder. Other times, they use hole punches to make confetti or decorations for a party.
Hole punches come in different shapes and sizes too. Some can make little stars or hearts, and others can make bigger circles.
So, in short, a hole punch is a helpful tool that makes small holes in paper with a push of a handle.
