Which tool is specifically used to machine round holes into workpieces?

The drill bit is specifically designed for machining round holes into workpieces. Its geometry features a pointed tip and fluted body that allow it to efficiently remove material as it rotates, creating a cylindrical hole. Drill bits come in various sizes and types suited for different materials and hole depths, ensuring versatility in machining operations.

In contrast, while a lathe can also create round features by rotating the workpiece, it typically works on the outside or inside surfaces rather than being used solely for creating holes. Face mills and end mills are primarily used for surface machining and generating complex shapes, but they do not specialize in producing round holes like a drill bit does.
