What is the correct procedure after the countersink tool reaches the set depth?

When the countersink tool reaches the set depth, the correct procedure is to count and pause before stopping. This practice is important for ensuring that the countersink is complete and that the desired depth has been achieved consistently across all applications.

Pausing allows the operator to confirm the depth visually or through measurement, helping to prevent issues such as over-countersinking, which could weaken the material or lead to improper fitment of screws and other fasteners. This step ensures that the operation is done with precision and that quality control is maintained, ultimately leading to a higher standard of assembly in aerospace applications.

In contrast, simply retracting the tool or increasing the feed pressure may not allow for proper assessment of the countersink depth. Immediate progression to the next hole without pausing might lead to inconsistent results and could compromise the integrity of the assembly process. These errors can have significant implications in aerospace manufacturing, where safety and reliability are paramount.
