What is the process of using a drill bit to remove a circular area of material usually for fasteners called?

• A. Drilling
• B. Turning
• C. Milling
• D. Grinding

Answer: (A)

Drilling. This operation uses a rotating drill bit to cut away material and form a cylindrical hole, typically to accept fasteners like bolts or screws. The cutting edges on the tip and the flutes carry away the chips as the bit advances into the workpiece, creating the circular cross-section hole. This is different from turning, where the workpiece spins and a stationary tool shapes it; milling, where a rotating cutter removes material to create pockets or profiles on a surface; and grinding, which uses an abrasive wheel to wear away material and finish surfaces.
