Question

what tool should be used before drilling metal? * a) hammer b) center punch c) file d) hacksaw

Explanation:

A center punch is used to create a small indentation on metal before drilling. This helps the drill bit start at the correct spot and prevents it from slipping. A hammer is for striking, a file for smoothing, and a hacksaw for cutting—none are for marking the drill start point.

Answer:

B) Center punch
