Which holemaking operation uses a multi-point tool to machine a new hole into a workpiece?

• A. Reaming
• B. Tapping
• C. Drilling
• D. Boring

Answer: (C)

Drilling creates a hole from scratch using a multi-point tool. A drill has multiple cutting edges arranged around its tip, which together remove material as the bit penetrates the workpiece to form a new hole. The other operations have different roles: reaming smooths and precisely sizes an existing hole with a finish-cutting tool, boring enlarges or true an existing hole with a single-point cutter, and tapping cuts threads inside a hole rather than making the initial bore. Thus, drilling is the operation that uses a multi-point tool to machine a new hole.
