When should the air line be attached to the drill motor in relation to setting the drill stop?

Attaching the air line to the drill motor after setting the drill stop is essential for ensuring accurate depth control during drilling operations. When the drill stop is adjusted, it determines how deep the drill bit will penetrate into the material. By connecting the air line afterward, you can prevent any potential misalignments that might occur if the motor is activated before the stop is set.

If the air line were attached before setting the drill stop, the motor could be inadvertently activated, leading to accidents or an incorrect depth setting. This practice not only enhances safety but also ensures that the adjustment process is performed accurately, thereby leading to better quality work and adherence to specifications.
