I've never encountered a broken bolt stud that could be unscrewed that easily. Usually the studs break because they are stuck so tight that the force required to loosen them is greater than the strength of the bolt.
I think this bolt clearly snapped under use, and not while trying to disassemble it, if it was corroded stuck, this method wouldnt work. Unless he heated it up and broke the bond, and got enough corrosion solvent in there over time then this could work, but then it would be easier to just weld the bolt, as that adds both heat, and a way to turn the bolt again..
and one more thing, he used tap and blow pressured air on scrapped aluminum, not a good way of doing it in that situation, those scaps might have entered the engine even with the cloth there

In my forty plus years as a service engineer I would say I have removed maybe 50% of bolts like that but normally they are to tight to knock around, if you have a bolt that is snapped a good way down the hole a good trick is if you have a Lathe get a socket cap screw the same size and thread as the snapped one put it in the Lathe and drill a hole through the centre then put it in the hole were the snapped bolt is then using the same drill bit drill through the snapped bolt it allows you to get the dead centre you can then put penetrating oil down the hole and use an easy out. I always keep a selection of different size bolts ready to use works a treat.
Or you can skip all that nonsense with the lathe and just eyeball it and use a center punch to make an indent so the bit doesn't skip out and drill a hole for the easy out.

It depends on why it broke. If it broke due to shear stress then it is usually loose like this. If it was cross-threaded or over torqued then it usually has damaged the threads and has to be drilled out.

I normally use a center punch to: A. Shock the broken bolt, THEN: B. use a left hand drill bit and SLOWLY drill at the center punch mark INTO the broken bolt. MOST of the time, the bit will bind into the broken part and back it out for you. If not, then you can use an extractor in the hole made by left hand drill!. TIP: A bit of grease will catch the shavings and keep them out of the engine.
Bolts usually break because they're seized in. This bolt came out much too easily. The thread was even loose. This isn't going to be the case, most of the time.
@@johnsolenski140 The bolt in the video didn't even need a drill. All it required was a punch to extract it. Hardly much of a challenge. The first half of the video about fitting a helicoil, wasn't even mentioned in the video title.

Hello, Thank you for the video. It was very informative concerning one method of removing a broken bolt and in this case in an aluminum casting. Using a punch to screw a set of threads on out the way they were going. I used to be a machinist in a Ford road truck dealership and removing broken bolts was part of my purpose and I did remove hundreds of them. I just want to bring up a couple of points. Point 1: It is seldom you get a broken bolt that will come out like you have just shown in this video. Most of the time, the reason the bolts are broken is because the threads are stuck in the threads the bolt is put into. Removing any broken bolt, I used to always try to use the method you have demonstrated first as it is the easiest. When I have tried what you have shown and the threads are stuck where they will not screw out, I try taping strait down on the broken bolt to see if that will break the threads free. If not, I will put some heat on the broken bolt and going forward, there are more invasive ways to do that will come next. Point 2: In the video, you attempted to surround the place where you were working with a cloth to keep from getting savings down in the head which will ultimately get into the crank case. You did good putting the rag around where you were working. But, the next thing you did was take an air line to clear the trips away where you could see. Well when you used the forced air, you just blew all those shavings and chips right up under the rag. Not Good.
a 50 cc engine not the same as a 350 F150 eh get a drill and left turn cutting edge be done . as for tapping I use duct tape and a good rag . keep the chips out . seen the same thing there goes the crank bearings lol
Exactly what you said, my experience is the same as you described, and also to keep shawings under control I use grese besides rag precut shape to fit snugly around the place which needs attention. This is pretty much untipical. Also lefthand drill bit is of great help.
To install a helicoil you have to first oversize the hole , thread and then put in helicoil. for the second bolt only one in a thousand will come out this way. A left hand drill bit will remove some and in the other case a small drill and an easyout will remove the bolt. If not drill out the hole with a slightly larger bit and either tap to larger size or tap and install helicoil.

@@Mondeo217 not true. the bolt is steel the block is alluminum. the steel welding will not stick to the alluminum. ive built up when the broken bolt was 1/2 inch inside with mig welding. then weld a nut on and take it out. somtimes the nut breaks off 2 or 3 times but keep trying because heat is your friend and every time you try your putting more and more heat into it.
I generally go with the concept that if it is liquid it cannot be stuck. 🙂 Seriously, anybody who is working with steel bolts in aluminum castings should be applying an anti seize when assembling the parts. It will also help to prevent stripout when tightening the bolts.
Antiseize is a better lubricant than oil and it acts as a sacrificial material under corrosion conditions. Specified torque is based on a specified lubricant and the friction experienced when using it. Using antiseize instead of oil makes it EASIER to strip the threaded hole when tightening. Even if you understand that, it's not possible to know the CORRECTED torque to apply. If antiseize is used for protection, it should NOT be on the working threads, but those at the top of the hole where the bolt is exposed to moisture. (BTW, The correct torque applied to polished stainless helicoil wire threads is also less that applied to a base material with cut threads.)

@@paulkurilecz4209 Hey two questions since you have a lot of experience. Currently cleaning/fixing up a 1988 Yamaha Moto 4 350 ATV. Over the years working on random stuff I always searched for good ways to remove rust from fasteners but ended up always doing it by hand with a wire brush mostly. I picked up an ultrasonic cleaner last week and some Evaporust and it has worked great so far with cleaning up nuts and bolts and small parts. As far as protecting them afterwards since the zinc coating is gone what do you recommend? Searched around a lot and it seems there is nothign that really holds up good besides coating them again but I really don't wanna invest the money nor do I have the space to set up a meth lab like zinc plating operation lol. For now the bolts I've cleaned are in a ziplock bag coated in WD-40 until I need them but really wanna try something else. Second question. Last night I was working on it and tried to remove to M6 screws holding the exhaust heat shield on. It was one of those "I know I should let these soak a few different nights before attempting it" moments but I tried anyways and sure enough snapped them. The broken bolts are sticking out about a 16th of an inch. What is a good extractor set that won't break the bank? I don't have a welder so that option is out. I was gonna drill a hole with a reverse drill bit and if that doesn't catch the bolt then I can try the extractor. Just don't know which set to go with. Thanks
@@z1522 Also a good idea is to use stainless steel fasteners with aluminum. When using carbon steel fasteners, if there is any moisture present the aluminum will be anodic to the steel and be wasted away.
Китайские болты ломает при стягивании . их просто отрывает. Эта процедура работает. Конечно лучше просверлить левым сверлом небольшое отверстие и забить в него шестигранник
I'm assuming the bolt broke when tightening because no corrosion is present. Nice presentation on Heli-coil prep and installation. This person is well-experienced on proper tapping procedures of aluminum, backing to break chips and clearing chips before they score the new threads. Nice video!
Господи я на одном дыхании смотрел эту очень сложную операцию по извлечению сломанного болтика. Хотя мне показалось когда он дул воздухом тот болтик сам уже начал выкручиваться. Одним словом мастер своего дела
Many years ago I had a stud break just below the surface of an alloy engine block. The guy who saved my bacon took a short length of mild steel flat bar, drilled a hole near one end, slightly smaller than the stud diameter. He then TIG welded the bar to the broken stud through the hole. He then just unscrewed it, the heat of the weld also helped free up the corrosion which caused the breakage in the first place. My broke stud was held completely tight... the method shown here would never have worked.
Great trick that almost never works. Only when the screw is completely free of contamination and corrosion and is not deformed at all. A little galvanic corrosion or rust or oil sludge and it doesn't work. If the bolt is cross threaded it doesn't work. If it is bent it doesn't work. If it breaks in tension, the top few threads are usually deformed and it doesn't work. If the screw is stainless it doesn't work. If a steel screw is threaded into aluminum, it doesn't work. I could go on. If you have actually tried this trick, then you have probably resorted to drilling and using an ez-out or welding a stud, or drilling and re-threading to a larger size, or drilling and heli-coiling, which is what you see him doing on the first of the two holes. Probably because the simple trick didn't work and he resorted to using a drill and drill guide to remove the bulk of the bolt, then a dental pick to try to pick out the remaining pieces, then ran a tap into the hole, found out that the thread was shot anyway, then bored it over, tapped it, and put a heli-coil it. Note that you can see the stub of the broken screw in the first hole before he starts tapping, then there is a cut at 1:47, and turns the tap back out and the screw piece is gone. These UA-cam tricks and "Next level process" videos always make anyone who has actually worked in a machine shop or repair shop roll their eyes back in their head. When you see "life hack." "next level," or "simple trick" in a youtube video, it should set off your bullsh!t detector.
I have used the hammer & punch or chisel method many times. I was born before easy-outs were invented & I couldn't afford a welder. What I have is patience and tenacity.
@@savage22bolt32 Yeah, I’d agree. This is all you need a lot of the time, and is the most basic method so you need to learn it first! On teaching it to apprentices I’ve often heard “ah, would never have thought of that!”
RIGHT ! Jeremy Hicks is 100% right. When the trouble is a broken screw...OK, sometimes it works, provided you got enough room for the maneuver. If the hole is too deep it won't be possible. In that case you must use a carbide drill and make a hole right in the broken screw. But when you got a broken tap...which usually is stuck, matters become more complicated. You get the job done if you have a tap extractor. Not a cheap chinese stuff as it will brake easily. The Walton stuff may be the right option.
Thank you for sharing. “One size” for this problem doesn’t always fit, but l like it when people share what worked cause sometimes it works and other times it doesn’t (and, you try something else).
This solution is effective only in one case: when the bolt breaks off while being tightened, and when it does not rest against the bottom, after which, usually, the thread “unwinds” and changes pitch if the tightening was carried out without observing the torque. therefore, you first need to make sure that the thread has not “unraveled” on the broken edge. otherwise, when turned out, not only the pitch, but also the alignment will be destroyed on the upper remainder of the thread.
Thanks for the tip. I'm no longer a mechanic and I used to do the same for hummv cylinder heads. But it doesn't work most of the time. I would use left handed drill bits too.
Simplest way is not to break the bolt in the first place. If it feels tight, apply a little heat to the bolt head only. Cool with air line and repeat as many times as necessary. It usually works after the first couple of applications.

I've used the same trick myself. I used a masonry nail as a punch with it being very thin, sharp and very hard. Take your time and care don't mash the hole or the end of the broken off bolt up.
Good idea, but left handed bits aren't very common. They're kind of hard to find, and I imagine they cost more than their regular right hand counterparts. Too, I'm not sure I could get used to sharpening a lefty. It would take some getting used to, for sure.
I don't recall ever breaking a lefty bit. I suggest a quality bit (cobalt, carbide, titanium coated at the least. Gentle pressure, low rpm, DRY, Very slight off center angle of attack. You want the bit to Bite and reverse the fastener. Screw extractior comes next if need be Good Luck!
Now do one that is seized in there. That broke bolt could have been spun out with a left drive bit or a button magnet. What was the Heli-coil about???? This was easy peazy~!!
Over the years 55 + in engineering within a brewery. I have several times and it worked for me. Usually when the bolt had had a thick washer or spiring washer beneath the head. But cannot speak as when heavy handed fools employed a swing bar or a length of pipe over a spanner. Know your limits and have some idea to stretch and yield elasticity of a pin. But in the end experience says more than haste.
I see this video was just over eight minutes long. Good job tho . But if you have never tried left hand drill bits you will be greatly surprised by trying them. This would have took less time to do than it took to put the bit in the drill . But you did great your way also . Thanks
O truque, afinal, não é tão simples como parece, caso o parafuso esteja bem firme dentro da rosca. E geralmente parafusos quebram justamente por estarem presos na rosca. A melhor maneira é usar um punção e marcar o centro do parafuso e depois ir furando com um broca fina (de widea, melhor) e enfim usar um extrator se necessário, já que às vezes dando reverso na furadeira (bem devagar) a broca "engancha" no parafusos e este sai numa boa.

One of the best ways to remove a broken stud is with a left hand drill bit. More often than not the drill bit grabs the stud and backs it right out. I have to do this almost every day taking stainless screws/bolts out of either aluminum or stainless holes and sometimes cast iron.
Exactly. Plus this video seems unreal. Left over broken bolts are rarely this loose in the thread. I saw an awesome method to center the bore exactly in such case: use a door hinge centering drill 'bit' to start the whole. Then you can use the left hand drill and easy out if necessary.
I've been working as a mechanic fifty years and breaking a bolt by over tightening often leaves the broken piece loose enough to work out this way. The hardest to remove are almost exclusively broken because of corrosion locking the threads to the aluminum. I would agree, using every possible advantage is the best way to least impact the strength of the aluminum threads.
В бытность работы мотористом частенько отламывал болты (особенно у зил-120?) на головке блока , но ни разу при отломе, отверстия там не было, чтобы нарезать резьбу. И приходилось сверлить, потом забивать что-то твёрдое и выкручивать Ну или же иметь сверло, может метчик левосторонние.

What caused that steel bolt to break in an aluminum head? Too much tension (tightening) should have stripped the aluminum threads, like in the first hole. It didn't break by hitting the hole bottom before the seating of its head, and it didn't break because the threads were seized. These look like valve-cover bolts, only. If you broke the bolt and you know why ard how you broke it, you might avoid the same mistake and not have to resort to removal techniques. The "trick" shown here is a good one to keep in your mental "tool box" for many situations, however as the comments show, the video otherwise mostly shows many mechanic's flaws. It sure got a lot of views and comments though! Perhaps the best illustrated "trick" is how to write an alluring U-tube title. It addressed a VERY common problem mechanics face, often from their own clumsiness, and promises a "simple" solution. The next great U-tube "Gotcha" title: "How to lose weight by eating all you want while only sitting and watching U-tubes!"
The best way is to take out the whole piece and drill the broken bits with smaller drill bit on a perfectly horizontal surface. The way it is done here, there may be problems later when fasterning back the machine as the screw trade has been damaged. The method show here not in line with precision engineering.
Some people add a little bit of bearing grease in the shred collecting portion of the re-threading tool. This way it lubricates the cut and collects the material keeping it in that gap rather than it slipping between or rubbing into the threads.
You could use a drill bit that runs counterclockwise to drill a center hole in the broken bolt. If the bolt is loose enought the drill would back out the bolt.

I normally use a center punch to: A. Shock the broken bolt, THEN: B. use a left hand drill bit and SLOWLY drill at the center punch mark INTO the broken bolt. MOST of the time, the bit will bind into the broken part and back it out for you. If not, then you can use an extractor in the hole made by left hand drill!. TIP: A bit of grease will catch the shavings and keep them out of the engine.
That is the best and surest way to have the job done.
Bolts usually break because they're seized in. This bolt came out much too easily. The thread was even loose. This isn't going to be the case, most of the time.
Agree best fix for the bolt shown in video. I would add to leave the drill bit loosely chucked as to not break the drill off in the broken bolt.

Эффективная замануха - наше ВСЁ!!!
Hello,
Thank you for the video. It was very informative concerning one method of removing a broken bolt and in this case in an aluminum casting. Using a punch to screw a set of threads on out the way they were going. I used to be a machinist in a Ford road truck dealership and removing broken bolts was part of my purpose and I did remove hundreds of them. I just want to bring up a couple of points.
Point 1: It is seldom you get a broken bolt that will come out like you have just shown in this video. Most of the time, the reason the bolts are broken is because the threads are stuck in the threads the bolt is put into. Removing any broken bolt, I used to always try to use the method you have demonstrated first as it is the easiest. When I have tried what you have shown and the threads are stuck where they will not screw out, I try taping strait down on the broken bolt to see if that will break the threads free. If not, I will put some heat on the broken bolt and going forward, there are more invasive ways to do that will come next.
Point 2: In the video, you attempted to surround the place where you were working with a cloth to keep from getting savings down in the head which will ultimately get into the crank case. You did good putting the rag around where you were working. But, the next thing you did was take an air line to clear the trips away where you could see. Well when you used the forced air, you just blew all those shavings and chips right up under the rag. Not Good.
a 50 cc engine not the same as a 350 F150 eh get a drill and left turn cutting edge be done . as for tapping I use duct tape and a good rag . keep the chips out . seen the same thing there goes the crank bearings lol
Exactly what you said, my experience is the same as you described, and also to keep shawings under control I use grese besides rag precut shape to fit snugly around the place which needs attention. This is pretty much untipical. Also lefthand drill bit is of great help.
exactly,
the rags purpose was useless when he used the forced air
Eu, inainte de a posta o filmare de acest gen, în primul rând cred că mi-aș tăia unghiile 😀
Man, stop trying to convince him. In India anything is possible. It's full of UA-cam with such engineers
To install a helicoil you have to first oversize the hole , thread and then put in helicoil. for the second bolt only one in a thousand will come out this way. A left hand drill bit will remove some and in the other case a small drill and an easyout will remove the bolt. If not drill out the hole with a slightly larger bit and either tap to larger size or tap and install helicoil.
Болтающийся остаток болта можно было выкрутить выверткой левой и не долбить полчаса. А с такими когтями можно было прям ими как отвёрткой крутить 😂

@@Mondeo217 not true. the bolt is steel the block is alluminum. the steel welding will not stick to the alluminum. ive built up when the broken bolt was 1/2 inch inside with mig welding. then weld a nut on and take it out. somtimes the nut breaks off 2 or 3 times but keep trying because heat is your friend and every time you try your putting more and more heat into it.
I generally go with the concept that if it is liquid it cannot be stuck. 🙂 Seriously, anybody who is working with steel bolts in aluminum castings should be applying an anti seize when assembling the parts. It will also help to prevent stripout when tightening the bolts.
Antiseize is a better lubricant than oil and it acts as a sacrificial material under corrosion conditions. Specified torque is based on a specified lubricant and the friction experienced when using it. Using antiseize instead of oil makes it EASIER to strip the threaded hole when tightening. Even if you understand that, it's not possible to know the CORRECTED torque to apply. If antiseize is used for protection, it should NOT be on the working threads, but those at the top of the hole where the bolt is exposed to moisture. (BTW, The correct torque applied to polished stainless helicoil wire threads is also less that applied to a base material with cut threads.)
@@psdaengr911 Please don't lecture to a licensed engineer who has spent a lifetime with threaded fasteners in life critical applications and the interactions between dissimilar metals.
@@paulkurilecz4209 Hey two questions since you have a lot of experience. Currently cleaning/fixing up a 1988 Yamaha Moto 4 350 ATV. Over the years working on random stuff I always searched for good ways to remove rust from fasteners but ended up always doing it by hand with a wire brush mostly. I picked up an ultrasonic cleaner last week and some Evaporust and it has worked great so far with cleaning up nuts and bolts and small parts. As far as protecting them afterwards since the zinc coating is gone what do you recommend? Searched around a lot and it seems there is nothign that really holds up good besides coating them again but I really don't wanna invest the money nor do I have the space to set up a meth lab like zinc plating operation lol. For now the bolts I've cleaned are in a ziplock bag coated in WD-40 until I need them but really wanna try something else.
Second question. Last night I was working on it and tried to remove to M6 screws holding the exhaust heat shield on. It was one of those "I know I should let these soak a few different nights before attempting it" moments but I tried anyways and sure enough snapped them. The broken bolts are sticking out about a 16th of an inch. What is a good extractor set that won't break the bank? I don't have a welder so that option is out. I was gonna drill a hole with a reverse drill bit and if that doesn't catch the bolt then I can try the extractor. Just don't know which set to go with. Thanks
@@paulkurilecz4209 Good on you. Using both antiseize, and proper torquing methods, ie
@@z1522 Also a good idea is to use stainless steel fasteners with aluminum. When using carbon steel fasteners, if there is any moisture present the aluminum will be anodic to the steel and be wasted away.

I'm assuming the bolt broke when tightening because no corrosion is present. Nice presentation on Heli-coil prep and installation. This person is well-experienced on proper tapping procedures of aluminum, backing to break chips and clearing chips before they score the new threads. Nice video!
He is just letting all the swarf fall into the engine.
He could have used his finger nails instead of the 2nd hand ground down pliers.
🤣
I clicked to comment the same exact thing! Lmao
He could have also used a vacuum cleaner instead of blowing with air the metal shavings into the engine!!
Could be a woman, fingers way too long as well.
I’d say a drill and Easyout would still have been quicker with less chance of damaging the upper threads with that homemade centre punch
Господи я на одном дыхании смотрел эту очень сложную операцию по извлечению сломанного болтика. Хотя мне показалось когда он дул воздухом тот болтик сам уже начал выкручиваться. Одним словом мастер своего дела
Many years ago I had a stud break just below the surface of an alloy engine block. The guy who saved my bacon took a short length of mild steel flat bar, drilled a hole near one end, slightly smaller than the stud diameter. He then TIG welded the bar to the broken stud through the hole. He then just unscrewed it, the heat of the weld also helped free up the corrosion which caused the breakage in the first place.
My broke stud was held completely tight... the method shown here would never have worked.
Great trick that almost never works. Only when the screw is completely free of contamination and corrosion and is not deformed at all. A little galvanic corrosion or rust or oil sludge and it doesn't work. If the bolt is cross threaded it doesn't work. If it is bent it doesn't work. If it breaks in tension, the top few threads are usually deformed and it doesn't work. If the screw is stainless it doesn't work. If a steel screw is threaded into aluminum, it doesn't work. I could go on. If you have actually tried this trick, then you have probably resorted to drilling and using an ez-out or welding a stud, or drilling and re-threading to a larger size, or drilling and heli-coiling, which is what you see him doing on the first of the two holes. Probably because the simple trick didn't work and he resorted to using a drill and drill guide to remove the bulk of the bolt, then a dental pick to try to pick out the remaining pieces, then ran a tap into the hole, found out that the thread was shot anyway, then bored it over, tapped it, and put a heli-coil it. Note that you can see the stub of the broken screw in the first hole before he starts tapping, then there is a cut at 1:47, and turns the tap back out and the screw piece is gone. These UA-cam tricks and "Next level process" videos always make anyone who has actually worked in a machine shop or repair shop roll their eyes back in their head. When you see "life hack." "next level," or "simple trick" in a youtube video, it should set off your bullsh!t detector.
These people are only aprendists, not qualyfyed techition.
I have used the hammer & punch or chisel method many times.
I was born before easy-outs were invented & I couldn't afford a welder.
What I have is patience and tenacity.
@@savage22bolt32 Yeah, I’d agree. This is all you need a lot of the time, and is the most basic method so you need to learn it first! On teaching it to apprentices I’ve often heard “ah, would never have thought of that!”
RIGHT ! Jeremy Hicks is 100% right. When the trouble is a broken screw...OK, sometimes it works, provided you got enough room for the maneuver. If the hole is too deep it won't be possible. In that case you must use a carbide drill and make a hole right in the broken screw. But when you got a broken tap...which usually is stuck, matters become more complicated. You get the job done if you have a tap extractor. Not a cheap chinese stuff as it will brake easily. The Walton stuff may be the right option.
You took the words out of my mouth!

This solution is effective only in one case: when the bolt breaks off while being tightened, and when it does not rest against the bottom, after which, usually, the thread “unwinds” and changes pitch if the tightening was carried out without observing the torque. therefore, you first need to make sure that the thread has not “unraveled” on the broken edge. otherwise, when turned out, not only the pitch, but also the alignment will be destroyed on the upper remainder of the thread.
Thanks for the tip. I'm no longer a mechanic and I used to do the same for hummv cylinder heads. But it doesn't work most of the time. I would use left handed drill bits too.
Simplest way is not to break the bolt in the first place. If it feels tight, apply a little heat to the bolt head only. Cool with air line and repeat as many times as necessary. It usually works after the first couple of applications.
cool, but you tell that to a bolt that just snaps from having been torqued up and heat cycled and just lost the will to live while installed

Left-handed drill bits work real good
Left handed drill bit is always my first option. Has worked more times than I would have expected.
Yes !
the best thing is to use a small metal tube in which to pass the left handed drill bit
so as not to damage the thread
Good idea, but left handed bits aren't very common. They're kind of hard to find, and I imagine they cost more than their regular right hand counterparts. Too, I'm not sure I could get used to sharpening a lefty. It would take some getting used to, for sure.
Does the bit ever break?
I don't recall ever breaking a lefty bit. I suggest a quality bit (cobalt, carbide, titanium coated at the least. Gentle pressure, low rpm, DRY, Very slight off center angle of attack. You want the bit to Bite and reverse the fastener. Screw extractior comes next if need be Good Luck!

Over the years 55 + in engineering within a brewery. I have several times and it worked for me. Usually when the bolt had had a thick washer or spiring washer beneath the head.
But cannot speak as when heavy handed fools employed a swing bar or a length of pipe over a spanner.

I see this video was just over eight minutes long. Good job tho . But if you have never tried left hand drill bits you will be greatly surprised by trying them. This would have took less time to do than it took to put the bit in the drill . But you did great your way also . Thanks
O truque, afinal, não é tão simples como parece, caso o parafuso esteja bem firme dentro da rosca. E geralmente parafusos quebram justamente por estarem presos na rosca. A melhor maneira é usar um punção e marcar o centro do parafuso e depois ir furando com um broca fina (de widea, melhor) e enfim usar um extrator se necessário, já que às vezes dando reverso na furadeira (bem devagar) a broca "engancha" no parafusos e este sai numa boa.
I use a left-twist bit.

One of the best ways to remove a broken stud is with a left hand drill bit. More often than not the drill bit grabs the stud and backs it right out. I have to do this almost every day taking stainless screws/bolts out of either aluminum or stainless holes and sometimes cast iron.
I have done this also .. if the bolt is broken off seldom easy to back out!!!!
Exactly. Plus this video seems unreal. Left over broken bolts are rarely this loose in the thread. I saw an awesome method to center the bore exactly in such case: use a door hinge centering drill 'bit' to start the whole. Then you can use the left hand drill and easy out if necessary.
Agreed, and or a left hand tap.
I get mine in HSS from the local bolt supplier
I've been working as a mechanic fifty years and breaking a bolt by over tightening often leaves the broken piece loose enough to work out this way. The hardest to remove are almost exclusively broken because of corrosion locking the threads to the aluminum. I would agree, using every possible advantage is the best way to least impact the strength of the aluminum threads.
I have used this method many times.
When you don't have a left hand twist drill.

What caused that steel bolt to break in an aluminum head? Too much tension (tightening) should have stripped the aluminum threads, like in the first hole. It didn't break by hitting the hole bottom before the seating of its head, and it didn't break because the threads were seized. These look like valve-cover bolts, only.
If you broke the bolt and you know why ard how you broke it, you might avoid the same mistake and not have to resort to removal techniques.
The "trick" shown here is a good one to keep in your mental "tool box" for many situations, however as the comments show, the video otherwise mostly shows many mechanic's flaws. It sure got a lot of views and comments though!

The best way is to take out the whole piece and drill the broken bits with smaller drill bit on a perfectly horizontal surface. The way it is done here, there may be problems later when fasterning back the machine as the screw trade has been damaged. The method show here not in line with precision engineering.
Some people add a little bit of bearing grease in the shred collecting portion of the re-threading tool. This way it lubricates the cut and collects the material keeping it in that gap rather than it slipping between or rubbing into the threads.
Right ! Grease is better.......
It's a simple trick all right, for a broken bolt that is LOOSE in its hole. ANYBODY can get those out!

Dokładnie tak było , naprawdę urwane śruby nie idą tak łatwo a często bywa tak że narzędzia do wykręcania urwanych śrub umieją się złamać , a wtedy to jest już dupa bo urwane narzędzie w śrubie jest z tak twardej stali że nie idzie tego ponownie nawiercić. Sprężyny do naprawy gwintów też są gówno warte , jeśli ktoś by chciał tak naprawić urwany gwint świecy to jest to strata czasu , chyba że naprawa była by wykonana na zasadzie : "gwarancja do bramy i się nie znamy".

0 out of 10 for good engineering practice. Nicely blowing all filings everywhere so that they can find their way into oil galleries etc. Brilliantly done.
