What tool is recommended for deburring holes in the direct ground stud procedure?

Using a flat file for deburring holes in the direct ground stud procedure is recommended because it provides precise control and effectiveness in smoothing the edges of the hole. Deburring is an essential step to remove sharp edges or burrs that can form during drilling or machining processes, which could otherwise cause damage to wires, connectors, or other components during assembly or operation.

A flat file is ideal for this task as it can efficiently remove material without significantly altering the dimensions of the hole, ensuring a proper fit for the ground stud. Additionally, it can reach areas where other tools might not be suitable or effective, allowing for thorough cleaning of the work surface.

This careful method not only improves the aesthetics of the assembly but also enhances safety by eliminating potential hazards posed by sharp edges. Using other tools like a sander, drill bit, or rasp may not provide the same level of control and precision, and could lead to further issues in the assembly process.
