About this deal

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. [3] X Expert Source Ryaan Tuttle

Stripped Screws with a Screw Extractor How to Remove Stripped Screws with a Screw Extractor

Double-sided extractors are some of the most convenient models as they feature the drill bit and extractor on a single reversible shank, eliminating the need to hunt for a compatible drill bit. Simply drill the hole with one side, then flip the shank to apply the extractor. Insert side 1 of the extractor bit into your damaged screw and use your drill to create a smooth hole. If none of the above techniques work then using a rotary tool is another option. Securely attach a thin cutting disk to your rotary tool and start to cut a thin slit in the stripped screw. Make sure it’s deep enough to fit a flathead screwdriver, but thin enough that the screwdriver has enough to grip. If your screwdriver doesn’t fit you may need to make the cut larger, but make only small cuts; if you cut off too much of the screw, a screwdriver will not catch and you will not be able to twist the screw. The rotary tool can scatter loose metal shavings around the device so make sure you wear your safety glasses.Always try to use the correct screw for the application, and make sure you use the correct screwdriver for the type and size of screw that you are using. I’m sure that we have all run into problems at some point trying to remove that pesky threaded screw that seems impossible to get out! But what are the best ways to do this? If some of the more DIY methods below don't work, professional contractors use screw extractor sets to remove stripped screws. Extractors are a special style of double-sided drill bit. First, use the squared-off end to out the damaged area of the screw. Then, use ridged conical end to remove the screw. Your drill should be in reverse for both steps in the process. Screw extractors are reusable, so keep one in your toolbox in case you run into another stripped screw. [11] X Expert Source Gino Colucci

If a different screwdriver doesn’t catch, then stop trying to use it so you don’t damage the screw even more. Make sure to use a drill bitdesigned for metal and be careful not to drill too far into the screw, or the head could come off. Apply a drop of thread cutting oil to the screw. Thread cutting oil is sold in big jugs at hardware stores, but you only need a drop. Tip the bottle over to splash a little bit onto the screw head. Cutting oil lubricates the metal, which means less time spent drilling and less wear and tear for your drill bit. Of course you'll have to make new threads if you drill out a screw. However, as a "weapon of last resort", the drill always works.Apply the WD-40 and wait for it to set. Then, firmly insert your screwdriver and twist. The WD-40 may just help you get enough leverage to loosen the screw. These handy devices consist of a drill bit that grinds a hole into the head of a screw and a threaded extractor that bites into this hole, gripping the screw so that the user can remove it with a drill or ratchet. There are many types and brands of screw extractors on the market, but few have the mettle to do the job properly. To use a screw extractor, begin by drilling a hole into the head of the damaged screw. Apply thread cutting oil to the drill bit prior to drilling. This will make it easier to drill through the metal by reducing friction. Having the right size extractor is crucial to successfully remove a stripped screw or bolt. With 35 pieces that include left-hand bits and extractor sizes ranging from 0.125 inches to 0.250 inches, one would be hard-pressed to find a screw, stud, or bolt this extractor set won’t fit. It consists of high-speed steel that can endure the heat created when metal drills against metal. This one may work if the screw isn’t too badly stripped. A larger screwdriver may fit into the stripped screw head, and you’ll be able to rotate it out with a little bit of fiddling.
