When drilling a hole in a piece of metal, the technician uses a center punch to

• A. Mark the surface for measurement
• B. Make drilling easier
• C. Remove burrs
• D. Cool the workpiece

Answer: (B)

The starting indentation created by a center punch gives the drill a definite point to bite, preventing the bit from wandering on smooth metal. That guidance makes drilling easier and more accurate because the drill stays aligned with the intended spot as you begin the cut. It’s not about removing burrs or cooling the workpiece, and while it marks the surface, the primary purpose is to guide the drill rather than measure or deburr.
