What tool is used for boring holes?
A hole may be drilled or bored; awls, gimlets, and augers also produce holes. An awl is the simplest hole maker, for, like a needle, it simply pushes material to one side without removing it. Drills, gimlets, and augers, however, have cutting edges that detach material to leave a hole.
