What is the process called that creates a spiraling groove with a single-point tool?

The process that creates a spiraling groove with a single-point tool is known as threading. This operation is specifically designed to form threads on a workpiece, which can include external threads on a shaft or internal threads within a hole. Threading involves a precise movement as the tool follows a helical path, which results in the formation of a screw-like spiral pattern.

This technique is crucial in manufacturing components that need to be fastened together securely, such as bolts, screws, and nuts. Understanding the threading process is important for crafting parts that will meet specific functional requirements in a variety of applications, from machinery to consumer products.
