Which tool is commonly referenced to assist with precise drilling in aerospace assembly?

The tool commonly referenced for assisting with precise drilling in aerospace assembly is the drill guide. This device is designed to ensure that holes are drilled at the correct angle and location, which is critical in aerospace applications where precision is paramount. A drill guide typically has a defined path for the drill bit, allowing the mechanic to maintain control and accuracy, which helps in achieving the necessary specifications for components that must maintain structural integrity under demanding conditions.

Drill guides are especially useful when working with materials that require exact placement for structural reinforcements or attachments, making it easier to align holes on both sides of an assembly. In the aerospace industry, where tolerances can be extremely tight, using a drill guide minimizes the chances of error that could compromise safety and performance.

Other tools, while essential for the drilling process, do not specifically enhance the precision of the drilling operation in the way a drill guide does. A drill bit is simply the cutting tool for creating holes, while a rivet shaver is used for finishing rivet heads after installation. A completion tool is not specifically designed for drilling but is more related to final assembly tasks.
