When drilling a small number of holes, checking the drill bit for damage "as needed or per work instructions" is the most effective approach. This method aligns with industry best practices, which emphasize the importance of ensuring that tools are in proper working condition without necessarily requiring checks after every single hole.

Regularly inspecting the drill bit during use allows the mechanic to assess its condition and functionality while keeping efficiency in mind. If there are specific guidelines or work instructions that indicate when to check the bit—based on operational experience or tool maintenance protocols—following those recommendations is critical to maintaining safety and quality in the drilling process.

For small quantities of holes, the frequency of checks can be more flexible, allowing the mechanic to focus on other aspects of the task while still being mindful of tool performance. This strategy avoids unnecessary interruptions while ensuring that a drill bit does not compromise the integrity of the work due to unnoticed wear or damage.
