Explanation:
The tool that uses the impact of a hammer to indent metal before drilling a hole, driving pins, or aligning holes in two parts is called a punch or center punch. A punch is a hard metal tool with a pointed end. It is used to make an indentation in the metal surface by striking it with a hammer. Once the indentation is made, it serves as a guide for drilling holes or aligning parts. For example, if you want to drill a hole in a metal sheet, you can first use a punch to create a small indentation at the desired location. This prevents the drill bit from slipping and helps to ensure accurate drilling.
