What is a critical step to avoid during the drilling phase when using a screw extractor?

The most critical steps to avoid during the drilling phase when using a screw extractor include allowing the drill bit to overheat and using excessive RPMs.

Overheating occurs when the drill bit is subjected to too much friction without adequate cooling or lubrication, which can lead to damage or degradation of the bit's cutting edges. This can happen if the drilling is not done at the appropriate speed and the material is hard or dense, making it difficult for the drill bit to function effectively.

Using excessive RPMs can have a similar detrimental effect. High speeds can contribute to rapid wear and overheating of the drill bit, reducing its lifespan and effectiveness. Instead, optimal RPM settings are crucial for maintaining the integrity of both the bit and the workpiece, preserving the quality of the drilled hole.

Choosing to apply even pressure, on the other hand, is essential and should be maintained during the drilling process, as it helps ensure a smooth cut and prolongs the tool's life. Therefore, avoiding overheating and excessive RPMs is fundamental to the successful operation of a screw extractor during the drilling phase.
