Which tool is commonly used to deburr holes in a pre-installed ground stud procedure?

The use of a flat file is particularly effective for deburring holes in a pre-installed ground stud procedure because it allows for precision and control. The flat surface of this tool can easily remove sharp edges and burrs from the hole's surface without altering the overall dimensions or shape of the hole. This is crucial in aerospace assembly, where the integrity of the installation is vital for safety and function.

A flat file's design facilitates working within confined spaces, which is often necessary in aircraft assembly. It encourages a smooth finish and reduces the risk of damaging surrounding materials. This controlled removal of burrs helps ensure that the ground stud can make a reliable electrical connection when installed, contributing to the overall effectiveness and safety of the aircraft's systems.

In contrast, other tools like standard files or chisels might not provide the same level of precision needed for deburring tasks, and a drill bit is typically used for enlarging or creating holes rather than smoothing them.
