Hold the drill bits up to the screw or fastener you need to remove. The right one will be slightly less wide than the screw head. When you find the right one, attach it to your drill. You can buy individual drill bits from hardware stores at a small cost or buy a whole set with varying sizes. Place the drill bit in the divot you created earlier. Move slowly as you begin to drill. Too much force will damage the screw. Focus on holding the drill bit steady so it drills straight down into the screw head. You will need to drill somewhere between 1⁄8 inch (3.2 mm) and 1⁄4 inch (6.4 mm) into the screw head. The depth depends on the screw extractor you have. Hold up the extractor to compare it to the hole you drilled. If the extractor doesn’t fit, keep drilling to widen the hole. Make sure the drill bit only drills inside the screw or else you could damage the threads.
