Broken Easy Out Inside a Broken Bolt - Extraction - Part 2
HTML-код
- Опубликовано: 25 ноя 2014
- This is the best and one of the only methods on how to properly remove a broken easy out that had been broken by attempting to remove a broken rusty bolt. In the previous video, as an example, Tom Grafton at Jerry's Broken Tap and Drill attempted to remove a very rusty seized bolt using an easy out. The demonstration showed that if a bolt breaks on the way out it generally means it's too seized for an easy out and will almost always break because the easy out is twice as brittle and half the size of the original bolt.
In this video Tom Grafton illustrates the correct professional method on how to remove a broken bolt or easy out utilizing a metal disintegrating machine (MDM). It's very common for an Easy Out bolt extractor to break when trying to remove a busted, rusty, seized old bolt. Sometimes its best to save your tooling and let the professionals who use the right tooling to extract the broken bolt which will save time and money in the long run.

Excellent videos. No loud obnoxious music, no cursing, no yelling, no long, boring and needless intro's! Real and professional!
I broke the extractor inside the bolt for my primary cover. Thank you for stopping me where I am, I'll find a professional and get mine fixed. Knowledge is power!
Mechanic for 25 years here. I have removed many broken bolts mostly by welding a nut on or if broke flush just weld a small nipple on it and grab it with vise grips. More so than less I wish your business was across the street from me! You are an artist at fixing screw ups or bad situations. I wonder what the cost us for this service.........
Outstanding work, I'm totally fascinated by watching a craftsman like yourself work your magic!
I can watch these all day! Please make more!!
thanks, we plan to, near future
It's a real treat to see someone who really knows his stuff, inside out. I have a feeling that if you couldn't sort a job then no one could!
A great watch....love your manner too!

Amazing. I'm one of those fools that attempted to do the job myself. But now I know exactly where I made the mistake. Great lesson. Thank you so much for making these videos.
I highly recommend them they removed my broken grade 10.5 bolt and broken extractor out of my motor and did it in a couple of hours and very affordable . thank you Jerry's broken tap
I used your video on the Toyota 2.4 head bolt problem with the time sert tool..worked like a champ..never have I seen a hard working guy with so many bruised and black finger nails..love ya brother from another old school wrench!
The only reason why I googled screw extractor was that I showed a technician what I learned back in the 90’s how I learned from my aircraft mechanic uncle on how to prepare a Screw Extractor(Easy Out) before removing the worn screw. I also YouTub’ed this because the technician that asked for my help removing the worn screw had 1/4” Bit Type Screw Extractors from Harbor Freight. I was too nervous to use it so I got my Hanson Screw Extractors from my box and removed the screw. What my uncle Fred(TWA Aircraft Mechanic) showed me is to shave the tip of the Screw Extractor on the grinding wheel. Uncle Fred never told me how much to shave but you showed that 5/8” of the Easy Out broke off on the smaller Extractor. I’ll measure my smaller diameter Extractors because I truly believe that I have been removing about 5/8” off the tip. After 30+ years in the Aviation Industry I’m still working nights and learning every day. Thank you and I’ll definitely look into your channel.
Thanks for the info Jerry, it makes a lot of sense. I find what you do very fascinating and hope to see more videos. Thank you.
Thanks for your comment Edward. We know have 5 videos and adding more.
One of those channels that just quit yet had such solid content.
Great video, Tom, thank you for posting. Loved every minute of it.
That's it I'm taking all my problem jobs to a professional machine shop. You got to have the right tool for the job.
Great advice on extractors. Next time I see an incomplete set of extractors at a yard sale, I'll imagine the poor soul who had his day ruined.
Never knew this type of machine or service existed. Thank You for the information.
These videos are worth gold! MDM is often used in repair of large marine diesel engines and I have often wondered why the technique is not used more often in normal shops. I see from these videos that the method is still a mixture of science, art and magic. Thank you for the efforts to make these excellent videos.
Very well executed & explained
Been in the automotive field for almost 40 years, never used a cheapo-off brand EZ out (either it was Snap-On or MAC) and more often then not, the tooling always broke. Although we just usually push the work off to our in-house machine shop, its nice to see how its done with an actual tool designed to do the job the right way.
Well done with these videos and wish you guys would put out more. Very informative indeed.
Honestly snap on and mac are not cutter manufacturers. They are still garbage. The problem like was explained here is that you are taking a smaller diameter cutter that while being harder is also more brittle if something is seized you will most likely exceed the torque capacity of the smaller tool and it will shatter.
Thanks Jerry, That's quite an amazing machine.
I've found if a bolt even acts like its not going to come out, that heating it very hot several times will finally get it to work loose. If I can get it to move just a little I'll get it going back and forth careful not to put too much on it, trying to increase the movement range little at a time until it finally comes on out.
Tom would be a cool guy to learn from.
That is a skill and an art. Wonderful watching a master work.
Great videos. Really informative and well done.
Thank you sir! Greetings from Greece!
always wanted to see this done
many thanks
This is art. Thank you sir.
I have wanted to drill this bolt so bad. But you just talked me out of it. Sound like I would just make someone’s job harder. Great video.
Great Video!
Love proper craftsmanship
Nice work, Jerry. Keep on fixing!
That is some well-taken advice thank You's.
Excellent work sir .great video anyway
+synthesizer301 Thant you, were happy you liked it!
@@tomgrafton8681 I HAVE A STARTER BOLT THAT'S SHEARED OFF FLUSH WITH MY ENGINE BLOCK. 350 CHEVY BY THE WAY. I DRILLED A HOLE AND THEN INSERTED AN EZ OUT. YES, THE EX OUT BROKE AS WELL. IS WELDING A BOLT TO THAT BROKEN PIECE MY ONLY RESOLUTION??? PLEASE HELP. THANKS IN ADVANCE. 👍
Havent had to do many broken bolts, but ive removed plenty of taps and drills, i usually will use a drill bar or guide of sorts if i have to use a hand drill. If im lucky and i have the room ill use a mag base drill, starting center punch and then with a carbide ball end mill to make a small pocket, this will allow my carbide drill to track straight, with a drill bit this is usually enough to be able to remove the remnants, if its a tap, it may take a few step ups of drilling to get it.
Finally i hear someone using the m'kay expression other than South Park🤣
Nice work btw
I use an EDM at the machine and fab shop I work at. It is the final solution if I can't get it out with a TIG welder. The EDM takes longer to set up and use , but it works when all else fails. One suggestion that works good for me is on small bolts and taps, drill a piece of 1/4" plexi-glass a hair bigger than the electrode and cut a groove for the coolant to escape. Position it over the broken bolt and clamp it down. It works as a guide to keep the electrode centered up on the broken small bolt or tap. I also use plumbers putty and sheet metal to make dams for directing the flow of coolant. Nice video.
I was thinking about that, do you just use continuous heat or do you have a cycle frequency with a coolant and a sacrificial electrode?
My crankshaft can still be saved by disintegrating the broken easy-out and broken bolt used to hold my pulley/damper. Thanks for the video.
Been successful removing and re tapping bolts (even a bleed nipple on my brake caliper) but I know there's a time coming..... Thanks for the heads-up on "easy outs", never fully understood the pitfalls but I do now!
Kevin Chamberlain Thanks for the comment. Tom

i aint never see someone tap a hole with such confidence
This guy is awesome!!
Great teacher
these techniques is art and require thinking outside the box.
Had to burn a broken 6mm tap out of stainless today. Great piece of equipment to have in the shop.
Just a great presentation. These are the fellows that save your bacon (...and your ass).
Great videos Tom! Thanks. Removing old studs rusted into an exhaust manifold has to be one of the toughest jobs for a mechanic. Weld a nut onto the old stud if you can, then heat it red hot and apply engine oil - not WD40 as most people think. WD40 often works great when applied to cold rusted parts, not so great if heating is needed. The detergent in common engine oils works much better if you give it some time to soak. There will be a LOT of smoke so good ventilation is needed. Keep applying the oil as it burns off and the part starts cooling. Then let it soak when the oil stops burning off.
Jim Manson Gently work the stud back and forth loosen-tighten, loosen-tighten if it moves just a few thousandths, and keep adding oil. If you can't get that first few thousandths of movement, then re-heat it red hot and apply the engine oil again.
+Jim Manson paraffin wax is the best lube at high temps try it
Great video. Always good to watch a skilled machinist work his trade.
Good video with blood and totally ignoring it
One must have blood in the game!
Yeah, I bet that old dude is tough as woodpecker lips. He reminds me a lot of my dad.
We had a hi school kid in a tool n die shop I worked in. It was the beginning of CAD drawings and each die part had its own drawing. Anyway we could tell what parts the highschool kid had roughed out because each and every one of his drawings has blood all over them.
Excellent vid and Im throwing out my easy outs.
Watch 9:25 he explains when easy-outs do work
I like your videos
Craftsmanship right there!!
I've never seen a machine like this before. like an EDM drill press…wild
Skilled machine engineers..
Thank you very much for these videos. I really appreciate them. 😊
I love how everyone amazed by his confidence with the tap doesn't realize that if he pops it the machine to undo the mistake is literally right in front of him, and probably easier to fix than the bolt since it's not a complete thread.
Did you see him tear the tap out of the hole damaging the thread hs he just chased. - He need to go see Mr Pete to learn how to use a tap. Hes technique is from Kanarcy. - He NEEDS the tap burner to be close by with hois technique.
Loved the video! Are you aware of any portable machines that will do the same thing?
Wise words
I'm a mechanic by trade and my easy outs don't get used very often. I don't even bother with lefthand drills on turbo and exhaust bolts I just drill and helicoil.
You the man
Great tip do they sell those machines at Napa or Harbor Freight?🤔
We demand moreeee
What kind of coating do you recommend to apply to a bolt that will be in contact with water, salt water or coolant?
Great info, how about a 304 stainless manifold stud in an aluminium head.. that was just recently changed and broken when the nut was placed on and torqued down. , The nut came off with some thread and it broke the stud flush with the head, however the stud IS bottomed out in a blind hole. What are my chances with an easy out? I believe my situation is different ... There should be no ceasing however it may be tight up against the blind hole. I'm not sure..
i hope this is me in 50 years
If one uses the higher end of extractors No dollar store/wal mart/home improvement cheap $4.00 set of extractors they do not snap as frequent. I just handled a rear differential project with a set of $50.00 extractors removing 3 broken off bolts From drilling to bolts out was 20 minutes. I went into project with a 99% failure rate (every one quoted it) "extractors are crap and break most all of the time". I think I broke 2 drill bits, set my extractor with a hammer then used a 1/2 in drill to back em out all 3 came out. So in closing not so much the mechanic/machinist errors when extractors break it is the cheap metal the extractors are made of. But yes in a few cases rust/seized bolts do need to be machined out.
So when's the next video? Interesting stuff here
What tap handle are you using? Is that a custom made handle?
Ok the threads on my ez out are now worn from two previous bolt extractions. My mistake is that I have then used a larger drill bit with the intention of using a larger ez out. The only thing I have accomplished is that I have shallowed out what was a decent depth hole from the original drill bit - should have just bought another ez out of correct size....so, what now? should I insert the correct size ez out and fill the bolt with weld. Could that work?
used the same idea minus the machine to remove nipples from pvc fitting and lawnmower blocks (mufflers).
At my shop we have a specialist we call in that uses a TIG welder to remove broken bolts, however when we call he ask if we have tried to drill on it and if we have, he will not come out.
You're videos are very informative and helpful. However, please ask your cameraman to hold the camera still. Us old guys get seasick very easily!
Would you mind giving the cost of these jobs? The difference between the customer trying to do it and the cost if the customer would have brought in before they drilled. Thank you. I love your videos.
The last easyout I broke was in the front hub of a ford truck it was the steering stop bolt and I ended up just using a die grinder and tungsten burr and ground the whole lot out, cleaned up after I ran a tap through it but it took ages, that method you use is very nice, is it a converted radial arm drill?
Electrarc tap burner. Actually a very common machine. They did used to make a remote head you could stick on a drill press but as I remember it did;t have vibration and defiantly had no power feed. , If you have enough work for one it's worth the 5 to 10+grand, but I'll take a Bridgeport any time. The is nothing you can that you can do with a tap burner that you can't get done with the mill , Just the tap burner is a little faster at broken taps, but I'd like to see you use a tap burner to drill a bolt hole circle or cut a gear.
Can you comment on if you ever break a tap when re tapping ?
Why did you not try heating the manifold to expand it round the bolt before snapping the easy out? Was this deliberate to show your high-tech equipment?
Do you guys know anyone in the KC area with this specialty?
I could watch this stuff all day, but I got stuff to do
Jerry how are you? Its 5 years. We miss your videos 💜 Let us know your alright 🙏
GOAT ‼️®™️ 👏👏
What is that machine called
But like me i can't afford a shop that specializes in gotten the bolt out . I have a lower control arm bolt that broke off i am trying to get out now i tried the bolt exterior but it not working so i at the point just drill the bolt out and rethread it .
I noticed another hole with a broken bolt.
I wonder if he used that machine to get that out.
That is a very large scale EDM. Who makes that machine?
will this technique work on a Mercury lower unit where 3 of the 6 mm (m6) water pump housing bolts seized, the easy out broke in one of the bolts, and a drill bit broke in the second bolt. Now I have an easy out stuck in one and a tip of a drill bit in another.
DAM, AND I THOUGHT THAT I HAD BAD LUCK!!! GEEEEZ!!! I HAVE A BROKEN PIECE OF EZ OUT THAT'S BROKE OFF INSIDE OF MY STARTER BOLT THAT'S SHEARED OFF.
This looks so complicated. We have a bolt that broke off under our car and the mechanic said we could drill it out OR have someone weld the plates together, eliminating the need for the bolt! What do you think?

He makes it look so Easy I know better. Thats a lot of skills. An expensive tools l bet he is expensive TOO. But very good work
What if it broke on the way in because some dummy (me) didn't have a properly calibrated torque wrench? Can I just grab the head of the broken side with vice grips and try to remove or do I use a specific extractor?
CDubs HasIt If it broke from over torque an easy out should? If it seized on the way in it will not! Tom
A stupid question: What is the major advantage to use very expensive metal disintegrator instead an accurate drilling machine? For example if we have a broken M10 x 1.5 bolt, it is quite easy to drill a hole through it with a good drilling machine with 8.2 mm or even 8.3 mm drill bit without harming the threads. Then you can use a small hook and pliers to get out the remaining bolt threads. And finally you clean threads with a tap.
Pili Pali Your partly right! The only way you can retap after drilling is to be sure all the bolt is out including the threads.Tom
Can you drill easy outs with carbide?
Nw.Caffers you can but it tend to get a little spooky when you hear crunching sounds from the carbide then you have to use elm to get the carbide out if you can’t shader it and remove all pieces.
Most of these applications are where a hardened tap or equally hard screw extractor has broken off in the hole; I'm not sure even a cobalt drill bit would get through that hardness of steel.
@@jimdavis8391 The answer is NO! I tried Cobalt yesterday and it barely dented the "EZ-out"... More like "EZ-break"! FML!
Respekt mister
Who are you now

Why don't they use left-handed drill bits
So I am wondering, anyone can help me out, I need a good brand of taps to buy but don't know which ones are good, I am using them mainly for stainless steel. I was told Dormer made good taps, is there any other good companies?
Greenfield maks taps specifically for stainless,,,,but grab your ass when you ask them how much they want for a set. we just buy them as needed for a specific job.
These ez outs are kind of dangerous and should be avoided at (almost) all cost, they can be good if something broke as you were installing it, especially if there was lubrication involved but bolts that are seized typically dont come out. The unfortunate (because of cost) best solution is to weld, if its seated deep you can use a copper insert tube down to the stuck fastener and then build up the weld from the fastener & up through the tube.
When using an easy out NEVER forget to lubricate the threads with Liquid Wrench or similar lubricant. Wiggle it slowly on the way out. Without the lubricant, you will break the easy out.
Better yet never use an easy-out. You have a better chance of hitting the lottery then getting a bolt out with an easy out. - If you are already drilling then go all the way and use right size tap drill and retap the hole. Worst case is you may have to use a Helicoil. ,,,or this birds beloved Timecert. ,,,,If he had a milling machine and knew how to us it if you have damaged threads you can drill and tap it to the next size up and tale a piece of stud rod and locktite it into the hole and then drill and tap it back to the correct size.No need to buy high buck thread inserts if you are more then a second year apprentice machine hand.
What is the name of the manchine you are using I never seen one before and I like the video
metal disintegrator
Thanks for that I could do with one of them at times it makes taken out broken bolts so easy
RIP
Blood and sweat but no tears.
i have an impacted tooth, and no insurance plan.
ya because everyone has one of these tools right.....
Everyone dont have a welder
If i had a complete machine shop and my engine wasnt in car i could get anything out to
@@randyberding6647 I FULLY AGREE WITH YOU BUDDY!!!
Yea, bit everybody has a tap burner, huh? ,,,, I wounder why nobody mentioned Lincoln "Extractor Rod" ?
Great videos. Have you ever seen the A-SURE OUT extractor? It can be removed in seconds if it breaks, no EDM or DRILLING. After seeing it, only a fool would use anything else! All materials and labor made in the USA! For over 100 years the bolt extractor has changed in many ways, however the failure of a bolt extractor seems to have been carelessly overlooked leaving all users the possibility of catastrophic failure. Help support an American company. Thank you.
it seems about @9:25 he sounded sober, now im not sure
