What should be the state of a drill bit before use?

The drill bit should be clean and sharp before use to ensure optimal cutting performance and safety. A clean drill bit enables efficient penetration into materials without clogging, while a sharp bit reduces the amount of force needed to drill, which minimizes the risk of damaging both the tool and the workpiece. Additionally, a sharp drill promotes better accuracy and a cleaner hole, which is crucial in aerospace assembly, where precision is paramount.

Having a worn or damaged bit can lead to poor performance and inconsistencies, making it critical to ensure the bit is in good condition before beginning any drilling operations. This is particularly important in aerospace applications, where part integrity and accuracy can significantly affect safety and functionality.
