Which of the following describes a machining tool that has two or more cutting edges?

A machining tool with two or more cutting edges is accurately defined as a multi-point cutting tool. This type of tool is designed to engage multiple points of contact with the material being cut, which allows for more efficient removal of material and can lead to quicker machining cycles.

Multi-point cutting tools are typically used in processes like milling, drilling, and certain types of grinding. Their design helps distribute the cutting action across several edges, which reduces wear on any single edge and can enhance tool life. They are particularly effective for operations that require a more significant amount of material to be removed in a single pass.

In contrast, a single-point cutting tool only has one cutting edge, which limits its application to specific operations like turning, where only one edge interacts with the material at any time. Other options listed, such as a turning tool and a grinding wheel, may have multi-point characteristics, but they describe specific applications or types of tools rather than the general characteristic of having multiple edges. Thus, defining a machining tool as a multi-point cutting tool captures the essence of having two or more cutting edges effectively.
