Next, switch the drill to the extraction point and with a steady downward pressure (and slow speed), allow the extraction point to bite into the damaged screw which you can then easily remove.

Use the side of the drill bit to pierce slightly at the top to allow the extractor to grip. (Polishing) Your drill bit should move clockwise during this process. 2.) Then turn the tool over. 3.) Remove the bolt screws using the extractor (spiral) side. Your drill should move the bit counter-clockwise during this process. Package contains. 4 piece screw extractor set Caution.
