True or False: Usually one turn is sufficient to properly deburr a hole.

Deburring a hole is an essential step in the machining process to ensure that any sharp edges or burrs are removed, which can affect the fit and function of parts in mechanical assemblies. The assertion that usually one turn is sufficient to properly deburr a hole is often correct because a single rotation with the appropriate deburring tool commonly removes the majority of burrs effectively.

When the deburring tool is properly matched to the size and type of the hole, one complete turn around the burr can effectively smooth the edge by cutting away the unwanted material. This simplifies and speeds up the deburring process, making it practical for technicians in an aerospace assembly setting, where precision and efficiency are critically important.

In other contexts, like larger holes or materials with specific properties, multiple turns might be needed, but the statement generally stands true for standard practices in deburring.
