USER FRIENDLY - Two easy steps, first you just need a drill, select a bit smaller than the damaged screw and begin the extraction by using the drill bit/burnishing tip and drill down to create a clean hole (make sure to run the drill in reverse during the process). Next switch the drill bit to the extraction tip and using consistent, downward pressure (and a slow speed) allow the extraction tip to “bite” into the damaged screw, and then you can easily remove the screw.
1.) Use the drill side to drill into the top a bit to allow the extractor to get a grip. (Burnish) Your drill should be moving the bit clockwise during this process.
2.) Then flip the tool
3.)Use the extractor (Spiral) side to remove the screw-bolt. Your drill should be moving the bit counterclockwise during this process.
