What component must you slide the drill stop forward until it touches?

In the context of using a drill guide in assembly and machining tasks, sliding the drill stop forward until it touches the drill guide ensures that you have accurate control over the depth of the hole being drilled. The drill guide serves as a reference point that helps maintain proper alignment and positioning of the drill bit throughout the drilling process. By setting the drill stop against the drill guide, you can establish a consistent depth, which is crucial for achieving uniformity and precision in your work. This practice minimizes the risk of drilling too deeply or not reaching the desired depth, both of which could compromise the structural integrity of the parts being assembled. Proper use of a drill stop in conjunction with a drill guide is an essential aspect of safe and effective drilling operations in aerospace assembly.
