Hey, John. Have you ever used a left hand twist drill bit for screw extraction? I have about a 75 percent success rate with left hand bits for bolts that aren't to bad. The hard part is centering the bit.
i have a small around 6mm broken nut below the surface on my fuel tank near the pump... i dont think i wanna weld or do anything involving heat because its on top of the fuel tank... any ideas? i really need some help on this... i dont wanna change the whole tank because of this!
The main problem extracting a broken screw `stub' stuck in is to drill a hole exactly at its centre when it is having a broken uneven face. To make even worse someone would have used a CENTRE & hammered pits to`ring it out' and failed miserably leaving havoc! A centre drill or twist drill break inside makes the situation mad! It is always easy to blame saying `You didn't drill exactly at the centre & You damaged the threads'(eg: Dia1/4"or 5/16"broken screws).I feel something more to be invented!
show us how to do this with a broken head bolt that is hardend steel, not a soft exhaust bolt, that is broken off even with the engine block and repairs or being done with the engine in a peterbuilt tractor. also almost forgot ,this is being do with a hand drill. studs are 5/8'. good chance it will not go as well as your demo. for a little bitty job like the demo. set of left handed drill bits are the way to go. when done right they are productive .
@fyfanharrusett - See if you can find a copy fo Sunnen's Complete Cylinder Head and Engine Rebuilding Handbook, I wrote it in 1998 - try ebay, because they are out of print.
try to weld a little tower on a bolt an squeeze it with a pliers, hit it with a hammer and just turn it off using with a spray u use. this is the way i do. its faster.
Much better choice of sound for your title slides. If I had one suggestion, it would be to turn down the sound levels on the title slides to match the sound levels of the rest of the video. Thanks for showing the correct technique to remove a broken bolt. I have always wanted to know how to do that.
Torx bits make tolerable screw extractors if you don't have anything else.

@joby613 - I use them when ever I can. Just removed a bolt from a flywheel a couple of days ago using a left-hand drill bit.

@NEVERENDS90 - you may have to change the tank, or at least take it out to remove the broken fastener

@Rokiz2006 You can't really do that when the bolt is broken off at the substrate like the one in this video.
