What type of drill motor is commonly used to drill pilot holes in assembly row JD2?

The commonly used drill motor for drilling pilot holes in assembly row JD2 is a 90-degree drill. This type of drill allows for better maneuverability and access to tight spaces, which is often important in aerospace assembly environments where components are closely fitted together. The 90-degree angle allows the user to position the drill in a variety of orientations, making it easier to achieve the correct angle for drilling without obstructing other components or tools in the vicinity.

In contrast, while other drill types like standard drills, right angle drills, and 45-degree drills have their specific uses, they may not provide the same level of versatility and accessibility required for the particular tasks associated with assembly row JD2. For example, standard drills are generally used in situations where there is ample space, and right angle drills might not offer the same compact design as a 90-degree drill tailored for specific assembly needs.
