Easy to Use: All you need is a drill and an extractor smaller than the damaged screw. Drill a pilot hole, choose a suitable extractor, let it bite, and remove the screw. The slim and non-slip design allows you to easily remove the broken screw without damaging the original hole. Wide Application: This professional screw extractor kit can be used for almost all types of screw heads, such as cross, Phillips, Slot, Torx, square, and hex. The damaged screw extractor kit is also suitable for drilling into soft materials such as wood and plastic. The powerful magnets inside the extension rod and adapter ensure that the screw extractor holds firmly in place and effectively removes damaged screws.
