What is the typical use of a drill?

• A. To create round holes in material.
• B. To cut threads.
• C. To deburr edges.
• D. To countersink.

Answer: (A)

Creating round holes in material is the typical use of a drill. A drill works by rotating a cutting bit that shears away material to form a cylindrical opening, with the hole size determined by the bit diameter. While other tasks like threading (done with taps), deburring (with a deburring tool), or countersinking (with a countersink bit) are important machining operations, they rely on different tools or specialized bits. Some drills can perform those tasks if you use the appropriate bit, but the standard, everyday function of a drill is to make round holes.
