Which is a common feature of a center punch?

• A. Creates a reference mark
• B. Drills holes
• C. Removes screws
• D. Aligns two pieces

Answer: (A)

A center punch is a tool specifically designed to create a reference mark on a workpiece. This mark serves as a guide for drilling, ensuring that the drill bit is positioned accurately and reduces the likelihood of slipping when starting the hole. By providing a precise indentation at the desired location, a center punch enhances both accuracy and safety in the drilling process, making it a fundamental tool in pipefitting and metalworking.

While drilling holes is an essential operation in metalworking, that task is performed by drill bits rather than a center punch. Similarly, removing screws involves tools like screwdrivers or pliers, which are tailored for that purpose, and aligning two pieces typically requires tools like clamps or jigs rather than a center punch. Thus, the primary role of a center punch is to effectively create reference marks, ensuring that subsequent operations can be performed with precision.
