Just compare each bit to the screw and choose the best size.Īs you can probably tell, we find double-ended screw extractor sets easier to use. The nice thing is that the double-ended bit already matches up with the proper extractor size, so there’s no guesswork. If you’re using a burnishing/extractor double-ended bit, you’ll need to kick your drill into reverse to use it properly. EXTRACTOR BIT DRIVERYou also want to use a drill for this process as the mechsnism on an impact driver doesn’t deliver a smooth action. Don’t ruin the whole thing by rushing the process. If you’re stopping to remove a screw, then there’s some value in protecting your workpiece. Depending on the size of the screw extractor you plan to use, you probably only need to drill down about 1/8″ to 1/4″. Keeping your drill bit straight, drill down slowly into the screw. To make your life easier, add a little bit of thread cutting oil to the head of the screw. Next, find a drill bit that has a smaller diameter than the screw you need to remove. EXTRACTOR BIT PROPro Tip: If you’re working a bolt or plug out of an engine, mind those metal shards – you don’t want them falling into the engine block! Step 4: Drilling a Guide Hole If that’s the set you have, skip the punching and drilling step. Some screw extractors have a burnishing end that you can use to drill out the screw head directly. This will create an indentation in the very center of the screw that will help guide the drill bit. To do this, you align a punch to the center of the screw and hammer it down lightly. With a basic screw extractor, you may need to provide some space in the screw head for it to work. That means drilling or expanding a hole in that old screw. You may also want a pair of gloves if you’re concerned about metal shavings cutting you. You always want to protect your eyeballs from debris.
