What should be avoided to prevent damage when removing fasteners with a screw extractor?

When removing fasteners with a screw extractor, applying excessive twisting force should be avoided as it can cause several issues. The screw extractor is designed to grip and remove broken or damaged screws by using a reverse thread to allow for easy extraction. However, if too much twisting force is applied, it can cause the extractor to break, potentially leading to further complications such as additional damage to the fastener, the tool itself, or the surrounding material. Excessive force may also lead to stripping the threads of the fastener, making it even harder to remove.

Proper techniques involve a moderate twisting force to ensure that the extractor can do its job without causing damage to either the extractor or the surrounding components. Additionally, using the right extraction tool, checking the drill bit, and operating at moderate RPMs contributes to a safer and more effective extraction process, reducing the chances of damaging the equipment or components involved.
