Prepare the electric drill for use, please do NOT used for the hammer drill or screwdriver.
STEP1-Select a drill bit slightly smaller than the screw. 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.
STEP2-Line the drill bit up with the center of the screw. 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.
STEP3-Drill a hole for the extractor. 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.
STEP4-Insert the extractor into the drilled hole.Twist the extractor with a wrench or drill. Grip the top of the extractor with a wrench. Continue to twist it counterclockwise until the screw pops free.
