Which of the following is not a type of punch?

• A. Center punch
• B. Prick punch
• C. Dot punch
• D. Cold

Answer: (D)

Punches are tools used to mark or set up holes in metal before drilling, and each type serves a different marking purpose. A center punch creates a precise dimple at the drill point, helping to keep the drill from wandering. A prick punch has a fine point to lay out tiny indentations that guide the drill and start holes accurately. A dot punch produces a small, visible dot for locating centers on flat workpieces, useful for alignment. The term described as cold is not a type of punch; it refers to a temperature or process, not a punch tool, so it isn’t one of the punch types.
