How to remove a broken bolt in a deep hole | remove broken bolt in recessed hole
It can be difficult removing a broken bolt or stud that is recessed in a deep hole as there are not many techniques to remove the bolts. Before attempting to remove any bolt, it is a good idea to shock the bolt first, then apply some heat and finally some spray penetrant (once it is cool). Drilling out the bolt is one of the few options that will work in this scenario. In this video I show two techniques that could potentially work when a bolt is broken in a deep hole or a bolt is sheared in an aluminium component.

Thanks for the comment
Joel you have a part number on those?
Joel Seim is it possible to change that part of the engine that he's working on? n can u tell me what part of the engine is called , mines cracked where the bolt is supposed to go in so now every new bolt keeps breaking in that part n the belt comes off
Irwin makes them also....for a fraction of the cost of snap-off im sure.

Trust me. The total satisfaction when the end of a broken bolt is finally in your hand really is one of life's pleasures.
Absolutely. Thanks for the comment
The anger/ fear/ frustration that I experience the moment I realize I have broken a bolt off below the threads. Trust me, it really stinks.
@MAD GRUMPYMAN A lot of the time it is because some 300 lbs gorilla who over torqued the bolt to the point of failure. I know a LOT of manufacturers cheap out, namely Vehicle manufacturers on exhaust bolts. For $10 more they could use stainless bolts and then no mech would ever have a problem removing them. But the OEMs are more interested in selling you on the colour changing interior lights and jimmy jims and hoohas than building a decent vehicle.
I hope to reach this orgasmic experience
Indeed!!
Usually when I snap off a bolt, it's because it's hopelessly corroded (that's why it wouldn't come out). Step one, drill a hole in the bolt. Step two, snap your drill bit off in the hole. Step 3, swear....a lot.
Or snap off the extractor...
That's the method I use too! Must have gone to the same school or something.

Or just buy a new one , which is a piece of garbage 😂😂😂
Just tried this method-and it worked! I now have a hardened broken drill bit tip in the center of a frozen, broken bolt..
What I usually do is just pretend I never started working on it and go drink a beer.

Drilling a bolt and using this to guide a drill bit into the center of a sheared bolt just saved my company tons of money and machine down time on an industrial machine. Also, it made me look like a resourceful, smart engineer. Thank you!
I'm glad the video helped Thanks for the comment 👍
You would look like a smarter engineer if you bought a "vented screw" which already has a hole in the middle. That will save a lot more time and money from labor of trying to get it dead centered.
You are smart because you bothered to expand your knowledge and learn from others .
@@ahndeuxgotta love it when people elaborate on their answer and actually give the names
yeah it a superb idea!
Over 20 years pulling wrenches and I've never thought to drill out a bolt and use as a guide. Great tips. Totally worth watching.
Thanks for the comment 👍
Thanks for his tip. Very good idea if there are enough threads.
Me too! 🤔
I concur.
Such a great tip to make a “hole centering tool”!,
I love the centring jig. A broken bolt is enough to make you cry. You instantly get that sinking feeling when you know the bolt just broke, however the feeling of joy when you're holding the broken little bastard in your hand once you've removed it is priceless.
Knowing you’ve won is the best feeling
That hasn't happened not once in my lifetime. Just a huge mess and two cobalt drill bits broken in the bolt for eternity
Worded perfectly! Clapping sound
I broke a head stud in a bored and stroked 5.3l last week. 3.5" down in a hole. Crazy how tough it is seeing how easily it broke. 5 days later and I've only made it a quarter the way thru. Went thru probably 9 bits. Got the hole off centered some. They don't make left had bits that long. Studs don't even have torque to hold them in, you torque the opposite side. But the bastard won't spin. I got a extractor stuck in it, gotta weld a nut on to spin it. Praying that finally works. Needless to say I should've spent the $400 on ARP studs instead of $140 Speedmaster. Don't ever trust them or their torque specs. I'll seriously probably cry manly tears of joy if I can get it out. Otherwise the entire engine comes out and goes to the machine shop. Would be a good time to upgrade to 1/2" studs even tho that wouldn't be needed for 900hp

I've spent 40 some years having to remove broken bolts out of situations like these. The idea of drilling out a bolt to use as a guide is an excellent idea. The idea of a hinge sighting drill is new to me, also. Great ideas!!
Thanks Terry 👍

@@ultimatehandyman Does anyone actually sell premade bolts with center holes already drilled?
@@NobleEndeavours123 Search 'vented screws'. They are not a common fastener, so may be difficult to source depending on your location.
Absolutely genius. I'm 42yo and never heard about or seen a hinge/ self centering drill bit. I've been fighting broken bolts for decades. This blows my mind and I'm ordering some now. I've got bolt extractors and left handed bits, but always have an issue drilling through the center of a broken bolt. Thanks for sharing.
You are welcome Thanks for the comment 👍
but who's got a hinge drill bit ive never heard of it but used to operate a big drill press machine, biggest drill bit was 54mm
@@351clevelandmodifiedmotor4 Also called a Vix bit. Traditionally used in woodworking to insure a drilled hole is centered in the hole already bored in a hinge. That way when the screw is fastened the hinge doesn't walk to one side or the other sending the door out of alignment. I would imagine thats why it's also known as a hinge drill, though I have never heard it called that. I have never considered a vix bit for this purpose and I have tons of them. Genius!

Thanks for the great educational video, and a huge thanks for not ruining it with crappy background music while you're talking. I don't know why some people are compelled to add annoying background music throughout the video. I usually click away.
Thanks for sharing. I never thought to drill a bolt as a starter. CLEVER!
People who can actually get easy outs to work are magicians.
It just takes practice. I use them all the time.
I never use them. Ive been removing broken bolts for many years by drilling the correct size drill & hammering in torx bits. Ive found paticularly on small bolts the tapered extractors can expand the bolt & make it even tighter.
@@heybird5660 That's a very good idea. I can see how the impacts from driving the torx bits into the broken bolts serve to help break the bolt free to turn easily.
Takes skill. To be honest, if I have a welder available. I'd rather weld to it and extract it.
The only problem I ever have with easy outs is centering the drill as breaks are never straight and it likes to walk
something that everyone seems to forget to mention about using left hand drill bits to extract a broken bolt is the importance of drilling in short burst with steady pressure, it's the constant stopping that allows the bit to dig in and begin spinning the broken bolt, also if the item is important enough the best easy out ever is a back ground tap, if easy outs have failed, as a last resort you take an appropriate size tap and put a reverse grind on the tip so it grabs spinning backwards, you may waste a tap but chances are you will save the part, this trick pulled me out of one of my most desperate situations ......
👍
Wondering will the extractor catch better on the threads of the drilled hole if you didn’t drill it in reverse ?
This is one of the best videos I have seen about removing broken bolts for DIY person. I "had" a broken bolts in my 2008 Chevy Cobalt automatic transmission pan. Thank you.
Wow, thanks!
Drilling out some bolts for different sized threads was a GREAT idea. I've drilled out wooden dowels to do the same basic thing, but your bolt idea is much more accurate and dependable! A quality set of bolt extractors adds to the enjoyment of having that lodged bolt finally land in your hand.
You are welcome Thanks for the comment 👍
I was taught by my old foreman and mentor, he said that “the harder the material is, the slower you go “ that covers drilling, tapping, lathe and milling work. Like the channel but love AEG tools more! Have a great 2020!
Machining is more of an art than a science.. Plus you have to have a fetish for bits... All kinds of bits.. Standard bits, end mills, taps/dies, ferrous oxide, cobalt steel, high carbon steel, etc.. Bits are your friends!! hehe
Great tips! I had never used a drilled out bolt to center the hole. I have done hundreds of snapped off bolts before. A tip back atcha! Use your wrench to turn the extractor in while tapping on it to get a better bite. It provides an impact driver like effect, and, I believe, in many of my extraction experiences, made the difference between a successful extraction, and snapping off the extractor.
A two handled tap wrench balances lateral forces to apply only torque to the extractor. This reduces risk of breakage of the extractor.
What bugs me is how fragile the extractors tend to be. I've snapped off enough of them to usually make this a nerve-wracking job. Drilling a bolt as drill guide is a great tip - thanks a lot for that one!
That's the problem - the screw extractors are so easy to break off inside the broken bolt. Then you have a huge problem.
You can always drill them out- kzhead.info/sun/aq58lqmFqXWgm5s/bejne.html&t
@@ultimatehandyman - thanks I watched that video on how to drill out a tap - very well done.
You are not the only one to suffer a "snap off". I avoid them now as usually causing more trouble then they are worth.
@@ultimatehandyman Cheers, mate!
I love seeing different techniques to help when you screw up so thanks for the upload.
So glad I found your socket head bolt jig technique. I had a broken recessed manifold bolt on my 5.7 hemi engine in a tight space that I was able to utilize your technique to extract it. Thank god because I couldn't find a local auto machine shop to do this job so I was at a real loss until I saw your video. I only had 5" of space to work with and there was no way I could get a hammer on a punch to mark center on this recessed bolt. The only real modification I had to do was to cut the drill bit shaft back about an inch so my right-angle drill attachment with the shortened drill bit could be inserted into the socket head jig. Thank you
You have no idea how good it is to read your comment. Often people give me grief, with comments such as- "try that in a engine bay" "it's easy on the bench" "try it when the bolts are rusty" etc. You have made my day by using the bolt guide and adapting your own drill bit to shorten it 😉 Thanks for the comment
@@ultimatehandyman All those haters just don't understand that these are just samples for techniques to try. Not every broken bolt can be extracted, using this method. Not everything is going to be perfect. People searching for a "one fix fix all" is living in a pipe dream. Thanks for showing off the techniques that you utilize to attempt bolt extractions.

Today this video taught me: 1) Center-drilled bolt to serve as a drill guide; 2) Use of a door-hinge guide fitted with left-hand drill bit; 3) "Swarf" is the name for the chips of debris that result from drilling/machining/etc.

@@ultimatehandyman I learned some of this owning Hondas in the 1960s, w/ straight blade screws-- no phillips. thanx.
Happy Customer . Muy bueno, práctico...
I dunno. 99.9% of the broken bolts I ever encounter are right at the surface of the hole and you could never use one of those drilling fixtures. Of the 99.9% the majority are completely corroded or jammed in the threads and even if you make a nice hole in the center an easy- out still won’t turn it. I usually have to get a small hole as close as possible to center and then progress up in size till I’m right at the edge of the thread and then try to use a tap to clear out the remaining thread of the bolt without tearing up the base thread. You are very lucky, it looks like all yours came out with easy- out extractor
If not already done you should patent those and have them produced for sale. I'd buy them
I'm glad I stumbled over this video. In the process of my first engine swap project and I've been teaching myself everything. I noticed a few bolts snapped from the exhaust manifold and I've been quietly panicking over them. This video probably saved my knuckles, cash and headaches easily.
I already posted this, but as you may not see it ... _I worked a diesel turbocharger bench (Cats)(mid-1970s). Many frozen and subsequentialy busted bolts on the exhaust side._ _Center punch the bolt, drill it, use a 'pick' to pull the remains from the threads. If the threads were damaged, drill the hole to a proper size, tap it and insert a heli-coil ... good as new and didn't take very long._
Exhaust bolts can be extra tough because of they've been heated so many times
Always use a torch on tight nuts to prevent breaking a stud.
"Quietly panicking." Very well put.
The name of the game is slow and easy don't get frustrated walk away first get the drill centered don't allow it to walk multiple heat and spray cycles heat pulls in oil especially if you can drill all the way thru bolt so oil gets to the backside of the bolt. If you have some of the bolt sticking above surface before you tear it up with vise grips put a nut on it and weld together heat From welder will help. Once you get it to break loose take time and work it back and forth. As you are removing it and it starts to tighten up screw it back in a little movement is better than none once again take your time if it's loose keep spraying it oil will work it's way around when loose
Nicely done. I particularly like the patience you showed when having extraction issues. Thanks.

Some four (4) years after you posted your video, serendipity guided me to it. Thanks a bunch. It was invaluable. Just think of how much money automobile dealerships make by forcing customers to buy new parts by claiming that an old rusted bolt has been broken (during routine repair I might add) and can't be removed! A plague on all their houses!!
I'm glad you found the video (good for me- bad for you) 😂 Thanks for the comment
Very, very well made "how to". the patience and clarity in your presentation demonstrates the patience and thinking needed to perform the tasks. My comment on the use of heat would be to use an electric heat gun and non contact thermometer, something I picked up in a BMW motorcycle manual. You only need to get to 110-130 degrees centigrade and this works for bearing istallatioan and removal as well as removing stuck bolts. Works best for alloy housings with steel bolts as the alloy expands more than the steel. Works while the alloy is still hot.
Wow, really well done. Using the hinge bit is genius, and the centering bolts another really smart idea. Thank you.
Thanks for the comment 👍
@@ultimatehandyman What if the bolt is very narrow (small diameter)? How do you get it out?
I need a hinge bit holder
I have removed hundreds of broken bolts, but I have never seen your idea of drilling a hole in a bolt for a guide. I guess your never too old to learn a new trick. Thanks for your time.
You are welcome Thanks for the comment 👍
Perfect tip for the dril bit guide! Also the left hand dril bit! Thanks! In my days I also 'welded' broken bolt or thread ends out. You can only not do it with very deep broken bolts. Lay done a similar size nut and weld it from inside out the broken bolt to the inside nut. Due to the heat, the broken bolt wil expand and crush any rust . Let it cool down totally and slowly turn it out. Most of the time it worked for me! Also a penetrant oil, q20,w40 works great but spray it days before and repeat it every day so it can do its work. In combination with tapping on it works also mostly. Good luck with your work and program!
This video helped me to successfully remove six broken bolts on a John Deer Lawn Tractor Spindle. I always use the anti-sieze compound when replacing Spindles, and this saves a whole lot of manual labor. Thank you for this very informative and detailed video.
Brilliant! I’m glad you found the video useful Thanks for the comment 👍
Some great ideas there. Have to say as a professional automotive mechanic I haven't seen to many deep broken bolts or studs. Most all are flush with surface or smidge below.
One site, most are flush or just proud of the surface, but on a couple of machines we get them recessed in the hole, which made me think of ways of getting them out. Thanks for the comment 👍
**TOO.
There is a differance between a professional mechanic and a handy man. Salute. Thank you for your service sir. The number of your likes speaks volumes.
As a Industrial maintenance mechanic w/over 20 yrs. experience can say I am found of left hand drill bits, and the use of guides like shown in this video is a must, as they never shear off cleanly it seems, and often when you get them drilled a bit, they will loosen and you can take a pin punch, or even a screwdriver jammed somewhat into the hole and back them out. The 'hinge-guide-driller' was a great idea..must admit hadn't thought about that one..but the bolts with holes made in a lathe, is something we used for years.
Thanks for the comment
once you drill right through the bolt it comes out easier, I think it reduces the strength and it cant apply the same gripping force. Plenty of penetrating oil and one turn out quarter back as if you are tapping a thread helps prevent breaking it in the first place.Oh and really impressive video
on broken bolts that arent flat I always start the drill 90 degres from the spot I want the drill to start in. what I mean is that someone will inevitably run over and check to make sure I know what I am doing, cause it looks like I am drilling sideways into the part. when the drill gets its start, move(while the drill is turning) to your correct angle and drill into the center of the bolt. you make a start where you want it to be, then adjust angle and it should be right in the middle. got this trick from an old machinist school book. originaly it was a way to get a hole started in precisely the right place and prevent 'walking' that also involved making punch marks just so to nudge the bit over to where you want it and I modified that. old books are better than the internet, you dont need electricity to use them.... also there was this thing called "proof reading" back in the day when printing presses were set type...
niceguy217 I have used a small awl and just tapped it out
Hollow bolts. Yep, definitely Industrial Maintenance Mechanic tools. Not what a "handyman" would usually be able to fabricate. Not unless his steam punk grandpa handed him down his old lathe.
As an old retired mechanic I have used a torx head bit drove into the drilled hole instead of the screw extractor. It works very well.
I've got to remove some broken exhaust manifold bolts today, and plan on using this method. Any tips or tricks to keep in mind?
Much appreciated. One more minor addition is to use a vacuum cleaner after drilling to ensure unwanted swarf is removed, further reducing the chance of thread damage.

Thank you! Cheers!
Thank you very much for this video. Many years ago, I was THE machinist in a Ford truck dealership and I did many things there including removing bolts that had been broken off in deep holes. The thing I am most impressed about in your methods is the way you made guides to center the drill bit on the broken bolts. The thing I want to say is that I did experiments on aluminum getting broken bolts out. It is a misconception that a cutting torch can damage aluminum castings. I made a fixture for a machine that one could bolt a valve body on to the fixture and the machine would exercise the valve body just like it was in a real transmission. To make these fixtures, we had to cut up an old worn out transmission case where the hoses from the machine could be married to the valve body via the fixture we made. I sawed the first case with a metal saw and that was slow. We tested cutting the case with a cutter we put on our milling machine still not real good. I spoke to a welder about the problem we had cutting the case up. He said bring me one of the cases and I will cut it for you in no time. He turned up his welder to very hot and used a carbon rod. He cut the case in no time using that method. I asked him if we could use a cutting torch to do the job and he said no. I called nonsense on him for what he said and he allowed me to try. I did and I was not able to cut anything on that aluminum case with the torch. The reason for it is that aluminum is a good conductor of heat and will dissipate the heat faster than the torch can heat it. Also, the larger the hunk of aluminum, the better. May not work on a small piece. I know the method works as I have depended it for years. I showed my son and he has used it being a mechanic who had broken off bolts before...etc. I urge you to try this method a few times on something that is no good to build your confidence and skill before using it on something important.

Those guides are an excellent idea. I've never seen those before. I'm off to get some bolts and make some. I'll have to use a drill press though. 👍
It should be easy enough on the drill press. I was going to do that, but it was much easier on the lathe. Thanks for the comment

Same. Living where I do broken bolts are all too common. These are all the techniques I would use. I hadn't seen the hinge tool before though. Wouldn't actually be that hard to drill some through holes in various bolts, which I think you were suggesting Big Ben, and use those as guides too.
Oh... And I unpause the video and that's exactly what he did, hahaha!

Solid video mate. In my time in an Aero engine workshop I learned a few techniques to remove broken studs and bolts and I've never seen the cap head bolt guides used. Nice work.

Nothing beats that feeling of removing a broken bolt cleanly.

Great video@@ultimatehandyman
You are very skilled at your trade. My only comment is to always blow ALL debris out of the hole before using the extractor. Grains of sand or bolt particles in the aluminum threads can destroy the threads during extraction.
BeerBBQMan your right
Or at worst your shavings get pushed into the threads and muck up the extraction process
I tried to tell him.....
Nah tipp them out cause you blow them they can get in your eyes and other places
That's really clever, thanks for sharing! Over my 40 yrs. or so of working on mechanical things I've always dreaded broken off bolts. Badly corroded ones are the worse and if you don't have your own machine shop equipment it's really challenging.
I had a guy with a Cummins in a Dodge with broken exhaust manifold bolts. I gave him a quote on exhaust manifold R&R then told him that the bolts will be T&M. Almost all of the broken bolts came out easily. Like put the left hand drill bit in there and turn it right out easy. One of them I actually had to tap in an easy-out, but it took next to nothing to break it loose. That was a good day.
The drilled out bolt trick is so brilliant it's amazing that they aren't generally available as an off the shelf item.

one of the MOST frustrating things in any workshop is a broken bolt. One of the MOST satisfying feelings is when you feel the broken bolt start to turn and you perform successful removal.

Any time! Thanks for the reply. :)
802 Garage--The hinge tool (spring-loaded drill bit within a metal body that fits into the hole) is generically known as a "Vix-Bit". They are made by the S.E. Vick Tool Co., Inc., Lakeville, MN 55044 and others; Bosch also makes them and there are some Asian imports as well. They've been around for years and are available through Amazon and many industrial suppliers like Grainger and MSC. I have to agree the drilled bolt guides are also invaluable. Perhaps another viewer knows of a company that offers them for those of us without access to a drill press or lathe.
He to the fucking point in stop talking bro
Use an endmill instead of a drill on broken bolts. Endmills don't walk.
I like the drill guides. You can even use hydraulic fittings they already have the centres bored out.

I wish I had seen this years ago removing steel bolts from aluminum cross members on Snowmobile rails. It was almost guaranteed the bolts would snap off trying to remove them. I usually went to the snowmobile bone yard and picked up another Aluminum cross shaft. The ones that held a bearing or bushing and an idler wheel would certainly break because you couldn't heat it with a torch. Usually the threads would strip out if the bolt did come out so it was an impossible job. I used tons of antiseize when reassembling the frame rails.Good video. I no longer do snowmobile repair.
Your samples came out so easily with easy-outs. It reminds me of my most amazing case of a broken water pump bolt on a Toyota. The broken bit was a the bottom of an inch+ of clearance hole down to threads deep in the cast iron engine block. Drilling a hole in the broken bolt with a long bit was easy enough - this was back when Japanese bolts were notoriously soft. To this day I still am totally amazed that I got away with a brazed extension (old valve stem) on an easy-out to get the bite deep enough. The broken part came out as easily as the samples in the video . Wow, did that really work?! I do like your tip with the alignment hole through a bolt. Too bad my cases are always near flush so no threads to engage. I tend to end up with grinding the end flat, if possible, and very carefully centerpunching for the drill, starting small and working larger, depending how well centered. My cases are typically locked in place with corrosion and easy-out has low chance of success. The best helper has been to head the part to dull-red with torch, which I suspect expands the bolt into the rust and creates a little clearance when the bolt cools.
Heat seems to work when nothing else does. Heating then shock cooling sure helps to loosen rust frozen bolts, but you still need liquid wrench and torque!

,I have been using small allen keys and grind the end into a 3 point,removed lots in my turbocharger shop.
Wonderful to see an expert modestly and efficiently at work!
👍
Extraordinary detail ! Super helpful !! I learned lots !!! Thanks mate . 👊🏼 🔥
This is such a brilliant solution, you should market these so people don't have to make their own. BTW: I use a left-handed drill bit when extracting broken bolts, it often unwinds it without the need for an easy out.
I had this idea in the 60s, everyone thought I was nuts, they would end up breaking the extractor off in the bolt
one of the bolts he removed he did with the left hand drill bit.
What is a left-handed drill bit? What brand is strongest for 9.8 Hex headed sheered bolt?
Something I have never been able to do successfully, thanks for the tips!
You are welcome Thanks for the comment 👍
That is amazing. What a great video. I appreciate that you took the time to put this video together. Thank you!
You are welcome Thanks for the comment 👍
One of the best videos on this topic on KZhead hands down. Bravo, my friend.
Wow, thanks! 👍
I have never heard anyone pronounced the letter T so powerfully has this guy
In the US, we say "dih-an" (didn't) and "stray-aned" (straightened). I actually prefer his correct pronunciation... It annoys the hell out of me when people leave out the second T (and other consonants) in many of our words...
Because he is from Lancashire and we speak proper
I just speak like 99% of other people in this area. It was only when I was 15 and went down South that I realised I had an accent, as people kept asking me if I came from Yorkshire 😂
Bloody scary 😅🤪
Preston? Or within a handful of miles.
The joys of bolt extractions. As much of a pain it is to do, it sure is satisfying when successful.
Absolutely! Thanks for the comment 👍
The jiys of bolt extractions N
I could hug you right now.... I had a bolt snapped in an aluminum head. I tried drilling and using the extractor but nothing worked. Then I found your video and realized that the one thing I forgot to do was to use the the extractor to punch again before extracting. Huge smile one my face when I felt it bite and saw it come out!😃
I'm glad the video helped Thanks for the comment 👍
The bolt is a great idea, key is keeping your hole centered, TY for that tip. Try turning the extractor counter-clockwise while tapping on it with a hammer seems to give it a better bite. Been a machinist removing broken bolts on aircraft for over 30 years. Glad i stumbled on this video!!!
Thanks, Greg 👍
Thanks for speeding up the slow parts. I didn’t know about left handed drill bits,,
You are welcome Thanks for the comment 👍
They are better then extractors in most cases..
The process works if the bolts are in good shape like yours(clean threads). I've worked on many bolts with corroded threads that no left hand drill bit or extractor would work. Instead of making those centering bolts, you can use a small bushing from the hardware store. Choose one that fits inside the opening.
Thanks for the comment
I do believe that there are some bolts that can not be removed. I recently replaced two brake wheel cylinders with bleeder screws broken off. To get some practice with such things I went to work on the old ones in a vice on the bench. A number of heat/cool cycles left hand drill/extractor, PB Blaster; tossed them out with the screws still stuck.
If the bolt is at least 8 mm 5/16" the best way to get them out is to weld on them and build them up out of the hole and the weld a nut on it and vola it in most cases can be screwed out. Just watch out you must use a chromium weld rod not a usual welding rod
YEAP!! but why a chromium ( stainless steel?) rod,please?
The character of the rod is that it is very accurate it does not fly to the side and the flux more or less isolate the side of the hole for any splatter and last but not least it is normally much stronger than normal rutil rod

Drilling out bolt to use as guide is brilliant
Thanks 👍
Nice! Remember to watch for metal shavings getting wedged in threads. Compressed air will blow them out.
Thanks for the comment 👍
allways blow out every bolt hole before replacing bolts more so if its rusty like a manifold
That was a really good video, and now I finally have a use for that bloody hinge drill, as I am a useless carpenter..... Subscribed!
Thanks for the comment
Thank you for sharing this. I love your strategy of making drill bushings out of socket head cap screws. Also, I like those drilling bit centering holders.
Thanks 👍
Great video. I enjoyed watching being I was a Diesel mechanic for 27 years. The tools you used to center the drill bit was genius. Sir you have talent. Nice work.
Cool, thanks 👍
Heat rusty bolts before they snap, also cooling quickly with the penetrating oil will cause a separation between bolt and job. The idea is to spray wd on the bolt itself so it cools and shrinks within the job, it also burns out the rust
WD sucks as penetrant . Just mix 50/50 acetone and auto tranny oil. Dirt cheap works as well as anything else out there
In my experience,despite all the rival claims,a sprinkle of holy water is just as effective.

@@drizler liquid wrench's penetrating spray outperformed the ATF/acetone mix. Project farm tested it out.
David Worsley - Amen to that.
Great video! I never have been good at extraction of broken bolts, but feel more confident to try with your methods!
It's hit and miss sometimes, especially if using a screw extractor. Thanks for the comments
Such a helpful video! I twisted off a bolt for the valve cover on a BMW R1200GS Boxer engine - not paying proper attention... What a conundrum. If I could not fix this myself I was faced with an expensive haul of the bike to s shop for a costly repair. instead, I followed the idea presented here to use the hinge centering tool with a left handed drill bit to carefully drill a pilot hole. It did not come out with the bit, so I then used a torx socket - tapped in with a hammer - to backout the twisted off piece. After a few drill/torx sequences, I was able to back out the piece with the socket. Such a relief! Thanks for the guidance!
Well done 👍
This and wiring aren’t jobs that I enjoy! Thanks brother does give me more confidence to not mess something up worse!
👍
The absolute worst is when you snap the extractor off in the broken bolt. 😭
Been there and got the Tee shirt 😂 At least you can drill it out- kzhead.info/sun/aq58lqmFqXWgm5s/bejne.html Thanks for the comment 👍
I was wondering the same thing. When either the extractor or the drill bit brakes off in the bolt. I've actually have had that happen to me.
Or the drill bit! Ughhh broken bolts/ stripped out threads are the worst!
Done it lol. Ended up dissembling the casing of the thing I was working on and sent it to a welder. He welded some shit onto the exposed tap and turned both the extractor and the tap out
Luckily these are all brittle compared to the bolt and you can hit them with a punch and shatter them

@@ultimatehandyman я делал проще просверливал (очень рядом) в шпильке 2 дырочки диаметр 2 или 3 мм, забивал туда заточеное плоское сверло оно разрубало мост между 2мя дырочками и отркчивал этим же сверлом так как на конце был квадрат и можно было ключом выкрутить но можно просто пробить мост между 2 дырками а откручивать уже мягкой сталью чтобы сверло (которым били) не лопнуло и не застряло вшпильке

Like a lot of other people commenting I'm 71 yrs old and this is the first time I've seen this drilled out bolt guide trick , pretty slick , great job .
Great to hear!
Many years ago I used a piece of round bar stock to make a drill bit guide to center up on a broken head bolt that was deep in the block. Since the bolt broke at the top end of the threads there was no way to use the Allen head bolts like you used, but I will keep the idea in mind! Many times I have used my Mig welder to build up the broken off bolt to get it up to the surface, then welded a nut on that. Of course I soak the broken bolt threads with Kroil first and sometimes heat the base metal up with a torch to help break any corrosion loose.
👍
You saved my butt again, thanks! A cheap set of left hand bits from harbour junk freight did the trick.
Thanks for the comment 👍
I've found that using a ratchet on the back of the screw extractors and applying pressure while twisting in most situations does a better job of biting into the bolts than using a hammer. Plus, less worry of a hitting wrong and bouncing off the threads. The drilled bolts for centering drillbits is nothing short of pure genius.
Thank You!
The drilled bolts are pure genius for sure. I wish we could buy a set in both metric and SAE. It would sure save time, instead of making my own.
@@ainsleyencinas21 Seems like that would be an opportunity for someone to market them.
Try using a spline type of bolt extractor set instead of the not-so-easy-out. You'll never go back.
@@WarpFactor999 Where do I get it?
Gotta say, I love the homemade guide. Drilling through a bolt to screw in and use as a guide was brilliant. Also, there are tap sockets made by Lisle and Irwin. The Lisle sit on the tap and lock on it. The Irwin are like a drill chuck, you turn it to tight it down so you can use a 3/8 ratchet. They’re pretty cheap and would be worth picking up (if you haven’t already).
