A center punch is a type of punch used to mark the center of a spot on a material, such as metal, wood, or plastic, to guide drilling or other operations. It has a sharp, pointed tip that is struck with a hammer or pressed to create a small indentation. This indentation helps ensure that the drill bit or tool stays in place and does not slip when beginning the process. Center punches are often used in metalworking, woodworking, and construction to provide an accurate starting point for further work. They are typically made of hardened steel to withstand repeated use.
