Definition: A "center punch" is a special tool that has a pointed end. It is mostly used in metalworking to make small indentations or marks on metal surfaces. These marks are helpful because they show where to drill holes.
In advanced contexts, you might hear "center punch" used in discussions about precision engineering or metal fabrication. For example, "The machinist used a center punch to ensure the accuracy of the drilling process."
While "center punch" primarily refers to the tool used in metalworking, in some contexts, "punch" can also refer to a tool used in paper crafting or a drink made with fruit juice and other ingredients. However, "center punch" specifically relates to the indenting tool.
There are no specific idioms or phrasal verbs directly related to "center punch." However, you may hear phrases like "hit the nail on the head," which means to be exactly right about something—important in precision work, though it does not relate directly to the tool itself.
