A milling cutter is characterized as a rotary tool featuring multiple teeth, which is essential for its operation. The multiple teeth allow the cutter to engage with the workpiece in a way that can efficiently remove material through rotary motion. This design enhances the cutter's ability to produce various profiles and shapes on the material, which is a fundamental aspect of milling operations.

The rotary nature of the milling cutter enables it to machine in multiple directions, allowing for complex machining tasks, unlike stationary tools that can only perform straight cuts without movement. Additionally, the variety of tooth designs and arrangements on milling cutters means they can be precisely tailored for different materials and types of machining needs.

In doing so, milling cutters can create surfaces that are flat, contoured, or even angled, providing the versatility needed in manufacturing and fabrication. Other options suggest limitations in capabilities or incorrect applications for milling operations, which does not align with the true characteristics of a milling cutter.
