What tool is typically used to deburr when installing a ground stud?

The use of a flat file in the deburring process is crucial when installing a ground stud because it effectively smooths any sharp edges or burrs that may have resulted from drilling or machining the surface. This is particularly important in aerospace applications, where any irregularities can compromise electrical connections and potentially introduce points of failure. By using a flat file, the mechanic can ensure that the surface is clean and free from imperfections, allowing for a proper fit and secure installation of the ground stud.

Tools such as wrenches, drills, and chisels can serve different purposes in assembly and maintenance tasks. A wrench is primarily used for turning fasteners, while a drill is utilized for creating holes. A chisel is used to cut or carve materials rather than for smoothing surfaces. Therefore, these tools do not provide the specific capability needed for deburring, making the flat file the most suitable choice for this task.
