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

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

Answer: (A)

Making a hole with material removal is most commonly done with a drill, which is a multi-point cutting tool. A drill has several cutting edges around the tip that work together as it spins and advances into the workpiece, removing material to create a round hole. This is the standard holemaking operation that directly forms a hole from scratch. Other processes serve different roles: milling can create holes in some cases but uses a cutting tool designed for milling actions rather than dedicated holemaking; reaming uses a multi-edge tool to finish and precisely size an existing hole, not to form it initially; tapping creates internal threads inside a hole rather than creating the hole itself.
