What is the function of the following tools in a workshop Punches, center punch, calliper and spanners?

1. Punches: Punches are used to create holes in materials such as metal or wood. They come in various shapes and sizes, and are typically used with a hammer to drive them through the material.

2. Center punch: A center punch is used to create a small indentation in a material, typically metal, to mark the center of a hole before drilling. This helps to ensure that the drill bit stays in place and starts drilling in the correct location.
