What type of punch is used to create a very small indentation?

A prick punch is specifically designed to create small indentations in a workpiece, which serve as guide marks for drilling or other machining processes. The slender, pointed tip of a prick punch allows for precise placement of the indentation without causing significant damage to the material, making it ideal for tasks that require accuracy. It is often used in metalworking and woodworking to ensure that subsequent operations start exactly where intended. This is particularly useful in scenarios where alignment is critical.

Other types of punches serve different purposes; for example, a flat punch is used for general punching operations and creates a larger hole. A center punch, while also used to make indentations, produces a deeper and broader mark that is typically meant for alignment before drilling. An indent punch may refer to punches that create various types of indentations but isn't as focused as the prick punch for precision in small marking. Therefore, the prick punch stands out as the most suitable tool for achieving very small indentations.
