What does a center punch do?

What does a center punch do?

• A. Marks the location for starting holes in metal.
• B. Measures thickness between two points.
• C. Displays cylinder pressure on a regulator.
• D. Separates technical orders by punctuation.

Answer: (A)

A center punch creates a precise starting point on a metal surface so you can drill accurately. The small indentation acts as a guide for the drill bit, preventing it from wandering as you begin cutting the hole. You strike the punch with a hammer, keeping it perpendicular to the workpiece for a clean, centered mark. This is a basic shop tool use in metalworking and maintenance to ensure holes go exactly where planned. It isn’t used for measuring thickness, displaying pressure, or organizing documents, which is why those options don’t fit.
