Remove a broken bolt using a left handed drill bit

Show me with a rusted bolt that's totally inaccessible up in the rear frame of my land cruiser...

[@Vic-lk1zq]

if the bolt head snapped off it's because it was in there so tight it took less torque to break the bolt than the thread seal.

[@mcmahon1130]

What a pointless comment. It goes without saying that the bolt needs to be accessible for this, or any other method, to work.

[@G34RH34D]

Same issue with me and a few rusted bolts on my Xterra I just recently bought. Bolt head snapped on surface or below the surface that go to the undercarriage.

[@doctorboy5892]

You have to drill it right out in that situation. Then re tap the thread. Your going back to the 1970's when we used to do that a lot as we kept cars 40 years.

The first method shown was spot on and saved me hundreds of pounds, after overtightening an M6 fastener that snapped on my egr valve. thanks

[@brucecollins5103]

So I see some doubters here, I've been doing marine and industrial repair and maintenance for close to 40 years now and I have a set of extractors and Left Hand cobalt bits in my box. They've saved a lot of work, and made a lot of believers. Drilling the bolt relieves the stress using the LH bit means all of the torque is trying to twist the bolt out and gives you a head start on the easy-out. And yes it works on rusty and bi-metallic corrosion and if you're lucky even on galled SS. Don't count on the last.

I used to work in the toolroom at a plastic injection molding facility. Removing broken hardware is a huge part of the job. By far the worse thing to remove from a blind hole is a broken dowel pin. I was just going to say that you can get easy-outs in sets. They have the appropriate size left-hand drill with them. Most often, the broken stud comes out with the drill and you don't even need the easy-out.

[@gbin21]

Do you have an idea how to do this if the bolt is really stuck ?

[@beyondwhatisknown]

Drill wider and wider exactly in the middle until there's nothing left of the bolt but the threads, then pull the helical threads out with a dental pick.

[@nomiclas]

the reason an eazy out is not the best answer is it creates expansion and hench causes additional pressure to the thread surface thus defeating the removal attempt.the left handed drill is a little known and seldom used quick answer,smart stuff.I would have used a little larger bit as it relieves even more side wall pressure but you really have to have your center and bit alignment correct if your take the tolerances closer.Nice job you just made many people's lives easier.

[@jerrybushman]

This video doesn't show a real situation but it does actually work. I drill a hole through the bolt first and then step with a LH bit. The first hole warms the bolt up so that when you use the LH bit it will shake things loose

I have many years of working on different types of machines . The best way if you have a welding machine weld a nut to the broken bolt or stud. after it cools down spray on penetrating oil and wiggle the bolt until it starts to move. If you have stainless steel to stainless steel and the bolt has frozen you are going to probably have to drill and re-tap the threaded hole.

[@yamahonkawazuki]

or use gradually larger bolts to thin out the walls of the bolt so eventually it can be removed in pieces. i do appreciate your videos. sending this one especially to an australian friend of mine. who has a broken exhaust bolt on a motorcycle he needs to remove

[@electronicsNmore]

Great video. For some applications this would work great(such as sheared off bolts). A left handed drill bit would never be able to remove a bolt which is seized in an engine block. Think about the amount of force it takes to get the head of a strong hex bolt(Usually grade 5) to twist off. The drill bit strength will not even come close. I have had broken bolt extractors break on me in the past, a few times. I just uploaded a video showing my solution to a recent problem.

As a forty year professional mechanic, I can sat you are correct. Yesterday I was extracting a broken exhaust manifold bolt from a 4.8L GM engine. It was broken flush. It's a rare occasion that a left handed drill bit will back the bolt out. One must first consider why is the bolt broken. Is it cross threaded, rusted, bottomed out? Most of those conditions is going to prevent backing it out with a left handed bit. What is worse, breaking off a drill bit or an easy out because those are hardened and makes drilling them out almost impossible. On the 4.8 L yesterday, it was just a whore. It was an 8 X 1.25 and I finally ended up drilling it out and Heli-coiled it to a 10 X 1.25 Fortunately is was a Savana Van and I was working on #7 cylinder. I had removed the motor mount bolts and lifted the engine to give me good access. It ended up being a good permanent repair and will outlast the life of the vehicle.

[@Gottenhimfella]

What people are not factoring in here is that *if* the drill is almost as large as the root diameter of the bolt, rather than as shown here, (in my experience) the remnants will not have enough strength left to hold themselves outwards against the female thread. Generally what's left of the bolt (effectively little more than a helical coil) will wind itself out if you feed increasingly hard so the drill bites before it gets right through. The heat from drilling also helps. If you don't have a left handed bit the right size, just sharpen the tip of a RH bit the wrong way.

[@A_90210]

I was livid when my screw broke off, now you give me hope.🎉

[@ultimatehandyman]

You are welcome Thanks for the comment 👍

[@sinajetta1746]

would it be okay to tap a new hole in a bolt that is fully ceased in a hole that the original bolt broke off in?

[@angelface2157]

What do you do when the drill bit beaks inside the bolt?

[@1Peter321]

If you can't extract it with needle nose pliers, then go to a shop that sells steel. They usually sell high grade drill bits. Buy a couple of drill bits instead of just one. You'll need to drill out the bit that broke off inside the bolt. Then you'll be good to go.

[@1Peter321]

You can also buy a titanium coated drill bit.

Love youre accent man, great vids! Sweden

[@HotAxleBox]

Hmm, I would like to see this done in a same scenario basis.. I.E. Rusted bolt in a threaded bit of old steep with a stainless steel bolt. As an engineer by trade I have found that this method generally doesn't work, the easiest solution is to use molycote or anti-seize compound on the threads before tightening/torquing the fixing. I prefer to weld a nut on the broken bolt and pull it out, or ld drill it out and tap the hole again, broken bolts cause flat threads (amongst other things)

[@Ax4400]

What do you do if you don't have a welder and you need to put your only vehicle back together? Hopefully that I put a crap load of anti-seize grease helps in using a left handed drill to back it out

[@pikachuthegayatheist6215]

I had to do the this on a fascinator got chewed out with my Dewalt titanium bits problem is is that they were right handed drill bits. I got lucky that the fastener came out, and because the Dewalt titanium bits come with a pilot point you don’t need a center punch to start your hole, you just need a lot of downward pressure.

[@ultimatehandyman]

Is it an exhaust flange gasket? If so it is very difficult to remove the bolts- unless they bolt right through and have a nut on the other end. Might be best to heat them up and then try and remove them gently!

[@tinocontreras5105]

Will this work on a broken sway bar bolt. Buying a truck that they welded the sway bar back cause the bolt snapped.

[@nomiclas]

another one is to use a center punch on the out board edge and tap lightly counterclockwise.I've had good luck with this if the bolt is not rusty.another thing about counter drilling,it depends on the metal Rockwell.if it is grade 8 or more most bits just overheat and won't cut the steel.for sure metal can't argue with abrasives!

The only times this happens to me are in super cramped places like the engine of my truck where I can't even make a center point due to lack of space to adequately use hammer, let alone a drill. EXTREMELY frustrating, especially when that bolt not being sealed causes oil to leak everywhere. I hope some day I'll encounter a broken screw/bolt in a nice open space like this so I can actually use the 50 bucks worth of extractor crap I have successfully for once.

[@FKPHW]

It's also known as a self-centering drill bit. The small bit in front acts as a pilot drill.

[@joandar1]

Some basic rules. 1 If it broke when you tried to unscrew it an extractor (easyout) 99% of the time will break in there. 2 You need to know how to find the true center of the bolt, the thread pitch is important here so you can figure out the true center. 3 If someone has already had a go before it comes to you then your problems have just started. 4 If it broke in a blind hole while tightening it may be bottomed out so will not be easyouted. I have drilled out extractors with tugsten drills.

[@hugonubario]

does it work on a broken screw stuck into rust? I got my screw stuck into the distributo shaft and it's stuck in rust

[@ultimatehandyman]

It depends how bad the rust is. Spray penetrant can help as well as come heat from a blowtorch etc.

[@hugonubario]

you can make them if you are skilled at sharpening drill bits, you just put the cutting edge on the opposite side, or in other word the back edge that would normally trail the cutting edge.

[@sh3lbot]

gogogeedus the rifling would be wrong.

[@gogogeedus]

shel bot Please explain?

[@AndyGarcia-oe5nf]

Would this shatter a brass screw?

[@ultimatehandyman]

Yes, brass is too soft and you will just end up drilling through it. Thanks for the comment 👍

[@stevenmason1674]

Left handed drill bit. I honestly didn't think they existed, always thought it was a joke like a left handed screwdriver, sky hooks or striped paint.

[@sh3lbot]

sky hooks hahhahaha! how about the good ol chain/board stretcher.

[@Brosko559]

yeah.. how often are they that large and flat

[@ozonegaz]

can you do the video again with the bolt seized into something see if it works then? thanks

[@Mrmotoman202]

will this work on my scooter? the spring broke and its horribly annoying, the brake drags on the back wheel which makes loud noises, any help?

[@RR-eg6gx]

Best exemplar taking out new bolt

[@ultimatehandyman]

"demonstration" ;-)

[@Daniel_Antonio_Arellano782]

My problem is the broken bolt is about 2 inches away from the firewall on my truck. But I didn't know left-handed drill bits existed Thanks for the tip.

[@ultimatehandyman]

Best of luck with it 👍

[@danschaap]

well i dont have money to get a quality drill of any kind lol so are you saying im screwed? btw the drill bits ive used are all new and i dont think any of them blut-end (not to sure what that would look like tho)

[@11111972cjb]

You are welcome Thanks for the comment

Thank you, Mr Ultimate Handyman 😍 I need to get a broken bent screw out of a bike frame. It was a screw for the kickstand. This I believe would work but was just wondering if you had any other easier ideas at all???? Thank you so much 💖

[@ultimatehandyman]

[@broadband2you]

Hi there, can u show us on a 3/16 and 1/4 broken bolt, please.

[@ultimatehandyman]

I tried with a 1/4 broken bolt once, but it did not go according to plan! kzbin.info/www/bejne/g4OVdZdpZbyYm9U 😂

[@terry.lcarmy]

We used left handed drill bits and left handed extractor with drill in reverse mode to take out a broken tensioner pivot bolt!

[@danschaap]

HELP! I was drilling into the bolt and it just stopped drilling. the bit is still rotating but it wont go in further. ive tried several new bits and they still wont drill any further. have any clue whats happening?

[@ryanmc2516]
