- In this video I drill out a broken tap using a JCB diamondtech holesaw. Drilling out a broken tap or drilling out a broken screw extractor is often very difficult and most people would get the broken tap or broken screw extractor spark eroded. There are not many drill bits that will drill HSS taps or screw extractors as they are harder than most drill bits, but the JCB Diamondtech holesaws slowly remove the hard steel. The Diamond Tech holesaw cost £17.50 from Toolstation (I’m not on commission) www.toolstation.com/shop/Powe...

YES! This worked for me. In the past I’ve used diamond hole saws on enameled cast iron, so I’m not sure why I didn’t try it immediately. Instead I tried the Dremel route, as recommended on many videos and discussion boards. The thing is, Dremel grinding stones wear away pretty quickly, and they aren’t all that cheap either. A 2-pack of conical burrs is $15 CAD, and I quickly went through about 4 of them grinding down maybe 1/3 of the broken EZ out. The diamond hole saw was $25, but it ate through the remainder in under 5 minutes! That’s with me being patient and frequently dipping in water as he does here. After that it was simple enough to drill out the sides of the hole, re-tap, and Bob’s your uncle. It’s also worth pointing out that multiple mechanics and machinists I spoke to didn’t offer any solutions to the problem. Kudos, man, thanks for the tip!
I can't believe you did this as a demonstration! You must love spending time in the garage. This situation is one of the worst
The main reason why I did this is because a few people commented on a previous video where I drilled out some broken bolts, normally with comments like "that's easy- try drilling out a broken tap", so I did. Now I'm waiting for the "it's easy on a bench- try doing that when you are in space - wearing a space suit" type of comments 😉
Thanks for the comment
@@ultimatehandyman this is easy. Just wait til you have to do it hanging upside down from the monkey bars while fighting off a pack of angry wolves and on fire. Ya! That'll make a man outta you!
I have to do this on an exhaust stud that broke in my mr2 and broke an extractor trying to remove the broken stud lol deff worth the watch I have to go pick up some of those diamond bits
@@ThePjstokes hey I have the same thing in my Suzuki m50 bike exhaust bolt right now! any tips?
@@druegeme make sure to stop for a tea every now and then
As always, great video 👏👍
In particular, your advice to “take a break” and “not to let it wind you up” is superb advice for someone who is learning about any jobs really.
Finally, I’d never even thought to use a “diamond tile hole saw” to drill out metal. I know I know, some will say it’s “obvious” - but it wasn’t to me. So thanks 🙏
You are welcome ;-)
Thanks for the comment
@@ultimatehandyman The “diamond tile hole saw” was new to me as well. Probably expensive, but a nice option if you can afford it (i have no idea what it costs, but its probably expensive). Anyways its on the list for x-mas presssies my loving family can bestove me with, but they will probably just give me a gift wrapped pair of second hand socks as usual. :)
@@clauspetersen840 Actually fairly cheap. That man has patience.
That cup of tea before the job gets on top of you makes the difference between smashing the whole piece, and continuing with the fine, slow and relentless spirit. thanks
Absolutely!
Thanks for the comment
Thanks for demonstrating a procedure which most of us try to avoid but sometimes you have to do it. As you showed, it's very time consuming and patience, care and persistence is essential.
Thanks
This video took a massive amount of time to film and edit, which is why there was no upload last Sunday (I’m also busy working and busy doing other things). Please like, comment and share the video (if you can), as it really helps me out.
I hope everyone has a great Sunday 😉
Thumbed up. I got a good sense of the effort expended in the work, let alone the post video work :)
I have a cast iron manifold on my old MGA with 3 rusted in bolts that I want to renew. I have tried heat and penetrating oil and a pair of nuts locked together but have not moved them at all - advice would be appreciated. You have provided some interesting ideas, I am impressed, thank you. Tony Clarke.
Studs that are rusted in can be a real pain. You have to be really careful with manifold bolts as they easily shear. I'd keep applying the penetrant, but also shock the studs by hitting the end of them with a punch and hammer. The shock can sometimes work wonders.
If that does not loosen them, you could try putting two nuts on the stud, tighten them together and then try tightening the studs slightly, before trying to undo them.
Best of luck with it ;-)
Good job altogether. These tasks are very challenging. Some great tips I never thought thought of before. Thank you,again.
link to the guide?
Kudos to your video and thank you for posting! I broke a bolt extractor, and your removal method was the only one that had worked. To make matters worse, the area was hard to access, so I had to get a right angle drill attachment and a quick release diamond hole saw. Turned out to be a two day job, but in the end I succeeded. Thank you!
Bolts always break in difficult to reach areas when I'm on site, they can be a real pain in the backside. I do get a lot of comments saying "it's easy when it's on a bench", I don't think some people realise that it's 100 times easier to film when it's on a bench!
I'm really glad that you managed to get the broken extractor out- well done ;-)
Thanks for the comment 👍
Oh man im having a bad time right now. I snapped a bolt on an exhaust manifold and then snapped off an extractor in the bolt. So I am in a simmilar situation. Worse thing is that I can't take the manifold off, without a garage taking the body off the vehicle.. so it's got to be done in situ. I have some solid carbide bits coming, and some diamond hole cutters coming as well. I am worried that I might snap a carbide bit off in the hole and then things will be even worse... so I will probably take the extra time to do it this way. It's good to know im not the only one, and if i take the time I will eventually get it out again. Cheers.
Persistence and patience and a'lil experienced know-how are INVALUABLE skills that help you out of the inevitable holes we all find ourselves in from time to time when life decides to kick you in the Jimmy's
😳💥🦵excellent 👌 content bro this is definitely one that goes into the life toolbox 🧰 keep'em coming 😎👍💰
I recall years ago being told the only way of doing this was via 'spark erosion' at a huge cost. This is a revelation. Thanks
The sound of crying when you broke the tap was me. Very, very impressed as I have always considered a broken tap deep within a stud hole as being an unrecoverable situation. A HUGE thumbs up.
Thanks Tony, once a tap is bottomed in a hole and snapped off, it is never going to be easy to sort it out.
I'm delighted that you found the video useful 😉
Thanks for the comment
I used this method as a last ditch effort and it worked!!! Broken bolt on a boat motor wouldn’t break loose after welding a nut on, heat, broke an extractor off in it, but this got it out. Took 45 minutes or so using his exact method! THANK YOU FOR POSTING THIS!!!
Nice work!
Thanks for the comment 👍
What a great video...being a much more experienced millwright at a food plant in Canada, I am constantly being asked to remove broken bolts/taps/extractors from stainless equipment! The younger ones just don't have the patience or experience in removing their mistakes. Once worked with an expert in a steel mill who was able to remove any broken object in a threaded hole. Cheers and thanks for sharing.
Rick from Hamilton, Ontario:)
Thanks Rick, we have a lot of stainless equipment at the place where I work and it definitely requires patience ;-)
Thanks for the comment 👍
Some stainless is a nightmare to tap. I go for less than 50% thread. Sometimes a lot less. Even the shadow of a thread can hold in stainless. I look in the hole and can barely see any thread. A fastener will still grip tight though.
Thank you for your work, Rick!
Thank you so much for uploading this video. I broke an ez out off in a transmission pan bolt and was able to remove it using your method. Your knowledge is greatly appreciated
You are welcome
Thanks for the comment 👍
This has to be an Ultimate Handyman platinum edition video. Pure gold at any rate!
Thanks for the comment 👍
I really like that idea to have a hole in the center of a bolt to guide your drill bit in nice and straight and not ruin any threads when drilling in the broken bolt !!!! Ingenious !!!!
I’m glad you found the video useful
Thanks for the comment 👍
I used a "rescue bit" to drill out a broke ez out on 6-71 blower cover. Was replacing the allen head plug with a vent button. Those rescue bits are worth every penny.
👍
Great video yet again....As a compulsive fixaholic I love to see stuff coming back from the grave.....I've spent a tenner to fix stuff worth a fiver just because I can! Keep up the good work!
Fixing things is always worthwhile, even if it's just for the practice of doing it. When I was a kid I remember replacing the element in an electric kettle for a elderly friend of the family. I bet you can't even buy a kettle element these days as electric kettles are so cheap!
Thanks for the comment
Would you drill out a brake caliper bleeder screw or buy a new caliper?
I love how the tap refused to play ball & break... & when it did, it broke in a place I have never seen a tap break in my 30 years experience as a machinist / repair guy... 🙄😂
If you could rig it so you were drilling vertically & had a continuous flow of cooling water, you would have speeded the job up... but thats not always possible.
Thank you for going through the whole effort to show the process involved...
Regarding tapping the hole or using an extractor... in situations like this particularly, I use a NEW tap, preferably a Presto spiral-point machine tap and use a good quality cutting oil like Rocol or similar, backing out, cleaning the swarf out & going in again ... patience is the name of the game.
I think its even more critical to use top quality extractors as they are almost glass-hard & very brittle. Presto brand was my favourite...and yet I have managed to snap even those... 😖
Carbide tipped masonry bits can be used in a pinch but need grinding to put a positive cutting rake angle on the tip...
There is a great sense of achievement & satisfaction in successfully doing a job like this, particularly if the part is expensive to replace or maybe even irreplaceable....
You've got a sub & a like from me based on this vid alone... good job mate 😉

Love the idea of a bolt as a centre guide, so simple and effective! Great video.
Thanks for the comment ;-)
That’s an excellent point about not letting jobs get on top of you
Thanks Luke ;-)
I ran out of patience just watching the drilling process. So I paused the video; got myself a "cup o' tea", and resumed the video. Thanks for the education.
@@cybair9341 Nice one 😂
I just broke off and easy out inside of a really small bolt in my dirt bike..... so depressed right now
Unfortunately, it's usually how you get into this spot in the first place. Definitely great advice.
From here in the States we say thanks for an excellent video and we definitely owe you a brew!
Ironically I'm drinking a brew right now 😂
Thanks for the comment 👍
When you were drilling you used a right hand drill bit. Would a left hand drill bit been better? Could it possibly help dislodge the broken bolt?
@@kseselja No, these diamond bits to not bite at all, they just grind away at the material.
Thanks for the comment
I started out with the diamond hole saw bit method you demonstated here but became discouraged with the slow going. I picked up a Milwaukee carbide multimaterial bit (4 or 5 inches long and looks like a masonry bit) at a home improvement store for about $8.00 US. With this, the broken extractor was completely drilled out within 10 minutes. I still needed to tap new threads as you demonstrate in the video. Thank you.
Great to hear!
Thanks for that.
I broke off an ezy-out screw extractor once and I eventually got it out by
using a spring loaded hole punch and breaking little pieces off the extractor
until it was all removed. It took about 4 hours.
It was a radiator hose thermostat manifold on a car engine.
One bolt came out OK.
The other bolt snapped when I undid it and then a screw extractor snapped off inside it.
I tapped it later for an oversize bolt from a metric to an imperial size.
It worked perfectly and saved a whole car engine.
Hot water from the radiator system had got down and
seized the threads of the aluminium to the steel bolt.
It should have had copper eze on the threads but of course it didn't.
Changing from metric to imperial or vica versa can allow a similar size bolt to be used without
having to use a Helicoil insert.
Wow, that was a long and difficult job!
Well done 👍
@@ultimatehandyman - thanks - at least I fixed it and all at home in a garage.
Thank you so much I’m fighting a broken easy out and bolt flush at the front of my crank this idea is the only one that seems to be working
You are welcome
Thanks for the comment 👍
This video helped me out no end. I snapped a stud extractor in my Porsche Boxster exhaust manifold a ruined countless drill bits and cobalt bits trying to get it out. 40 minutes with the diamond bit and it was dust! Keep up the good work!
I'm glad the video helped
Thanks for the comment 👍
You offer good solid advice! I’m a machinist in New York, I work often with aluminum 3/4 inch thick plate, usually sizes range from 19.00 x20.00 to as large as 36.00x30.00, either 6061, or jig plate. Saving a plate this size is a priority. We machine these plates on a VF6 Haas machining center. Occasionally, taps break. Since these are always in house items, I have a lot of leeway on how I extract the broken tap. My preferred method is to use a fractional size carbide end mill. Say for a 1/4-20 tap, I’ll use a 1/4 inch endmill. Usually 900-1100 spindle speed, sometimes flood coolant, other times I’ll use Moly-D cutting oil from a can. I crank down the spindle in the manual mode in tenths (.0001) with some luck, one endmill will survive doing the job, other times I’ll go through 2-3. Once the hole is cleared, I’ll re drill and tap for a 1/4-20 Heli-Coil insert.
Pretty much the same method I use as well. Although, you could use a 5mm carbide endmill, and not have to use a heli-coil. A 3/16ths might do it as well?
Wow. Thanks for sharing. Do you use a normal electric hand drill.
If your working with aluminum you can always dissolve the tap by soaking piece of aluminum for a few hrs or overnight in a heated solution of Battery Acid and Alum (potassium aluminum sulfate). method works great for aluminum but does take awhile. won't harm the aluminum in anyway whatsoever but it may discolor the aluminum but the discoloration rubs right out with a good aluminum polish or can just hit it with a piece of fine sandpaper. done this method many times breaking off small taps like 1.5mm and 2mm I use for aluminum parts for R/C vehicle parts and it works awesome. works well enough that I actually have a glass jar filled with the solution in garage just for those rainy days that ill need it. lol
AWESOME INFO, THANKS FOR THE SPEEDS, LUBE, ENDMILL INSTRUCTIONS!!!
If you're breaking taps frequently, why not buy a metal disintegration machine and do this job in a few minutes?
A lot of Time, Effort, and expense in showing us these Videos. Much appreciated. Thank you
You are welcome, Peter ;-)

I want to thank you personally for this thorough demonstration. I had a broken easy out in a broken bolt on a pickup hub. I was struggling to figure out how to solve this and your method worked perfectly! What a blessing. I am thankful for your generosity in sharing your knowledge. Praise God.
No space suit, but it wasn't exactly easy still on the vehicle. Your method works! Thanks again!
I'm glad the video helped

I've just ordered a set of diamond hole saws,your advice is spot on.
Thanks for the comment 👍
Thanks for another quality video. Your step wise approach to a difficult task is a lesson for all of us!
Thanks for the comment 😉
Thanks Chez
Again those bits are really impressive! It's certainly a way out if you're stuck like that.
But that "click" when the tap broke. Still makes my blood run cold!
I can still hear the bloke who taught me fitting!
You are welcome, Dave 😉
Yes, those bits are mighty impressive!
Thanks for the comment
Very good. If you break a tap its a disaster, usually. I am happy to learn that there are still options that does not require a repair shop. I liked the emphasis on self control. When i was a teen tinkering with stuff my dad always tried to teach me to take a 15-30 minute break when i felt a rage and need to smash things up with a hammer. It cost me a fortune in broken stuff before i finally learned the wisdom of those words. :)
5 out of 5 for this video!
I've been told that I have a lot of patience, but I do swear a lot when doing jobs like this- especially when I was on site!
A guy that I worked with on site had even more patience than me (Vinny Davies), he had the patience of a saint for sure!
Thanks for all of your comments 👍
Excellent video!! The mini tile hole saw saved me a trip to the machine shop and worked like a charm! Thanks Again!!

One thing that has made removing broken bolts/screws easier for me is the use Left-Hand drills when drilling out the center of the broken bolt because sometimes they will snag and turn the screw out for you saving time and effort. This would be after getting the center drilled if you were to use the drill guide that he made/uses. Great video and I will be looking for these JCB drills. Thanks so much!!!!!
Absolutely, left handed drill bits are great ;-)
Thanks for the comment 👍
Thought I would update on here as a way of saying thanks! This method totally worked for me. My situation was slightly different, because I had to do it in situ. Also the bolt I snapped off was smaller diameter (M6) and therefore the extractor was smaller too. I ended up going on ebay and purchased a pack of x10 4mm diamond hole saws, and because they are so small I ended up getting through all ten of them before getting through the extractor. But the pack of 10 was only about £10, so well worth it. I could then drill the rest of the bolt out and re-tap the hole. Great advice on taking your time with this job, it pays off!
Brilliant!
Well done for having the patience and perseverance to complete the job 🙏
Would a pack of 5mm hole bits be better? Was this a bolt that broke or a tap? I have the same issue.
What a pain! Hope i never have to deal with that. Thanks for the work in this.
I hope I don't have to deal with this again for a long time either ;-)
You are welcome.
Thanks for the comment
It’s a really good tip that taking a break helps get the job done. I bet you could have Jerry rigged some cooling once you had removed the guide bolt. My background is electronics and I am planning to build a spark erosion tool one day.
Absolutely, I've seen people get wound up over a piece of metal in the past and it does you no favours!
The spark erosion machine sounds ace, I'd love to see that when you have made it.
Thanks for the comment ;-)
Holy shit it worked. After I tried using a screw extractor, my drill bit broke inside the screw. I bought a couple of diamond hole saw bits from Lowe's and had it done within an hour. Retapping was so simple. Thank you for this video. Saved me from a major headache
I'm glad the video helped
Thanks for the comment 👍
Mr ultimate probably the very best thing you can add to you toolkit after the centering bolt is a set of left had threaded drills. I can sharpen my own drills by hand because I have done it so long. If you do sharpen your own make the bite very aggressive. It is many times faster than your method but it is very nice to have your method to fall back to.
Thanks for posting this. Worked like a charm and saved tons of time from teardown.
Glad it helped 👍
First off excellent job of showing how to get broken bolts out. I owned a radiator shop and we had to fight broken bolts in aluminum radiator tanks. Steel bolts in aluminum radiator tanks would seize in. The bit you used and the bolts you made are great. I would have bought them. I have a few other ideas.
1. If you had the hole pointing up you could have filled it with water or WD40 so you did not have to dip so often.
2. Snap-On makes a kit with reverse rotation drill bits. It comes with guides that center the hole. They are not as nice as the bolts you made. They are not threaded. But the screw extractor that comes with them is custom made for the drill bit size and works better than the tapered screw extractor.
3. I have heated up the broken off tap/bolt and let it cool slowly to soften it up. Then drilled it out. The cobalt bits are good but they are also prone to break off.
4. I have welded a nut on to the broken bolt with TIG welding and heated and backed it out.
5. I really like HeliCoils, they work great.
6. I have drilled out a bolt and moved up to the next size at times.
Final note: You could sell the bolts you made. I am old and retired, but surely would have bought or tried any new items to make a task like this easier. Keep up the good work!
Thanks for the comment, Patrick 👍
What you ran into is called the galvanic effect of dissimilar metals. Something to do with the covalent bonds of the atoms being different between the two metals. In effect they make a weak battery. Along with making a battery they corrode like a battery can too. Aluminum oxide is what sandpaper is made out of. So it's some pretty hard and abrasive stuff. Oxides being brittle can be used to advantage. Sometimes you just have to shock the monkey. Impact beats torque.
If your still around, I first watched video 4/8/2022, you've helped my dilema tremendously!!!! THANK YOU! I have subscribed.
Awesome, thank you!
I'm impressed!! Thought it might not be possible to get a broken screw extractor out but you made it look easy! Thanks!!

You are welcome
Thanks for the comment 😉
Thanks for another good video. I broke a screw extractor once. I initially thought "oh no" but due to the tapered profile of the screw extractor(SE) there is not a lot of contact between the SE and the bolt. I manged to knock it clockwise to release its grip and just took it out. A broken tap is a different matter. I would recommend before drilling the tap or SE to try something - anything you can think of to rewind it out of the hole, when all else fails then move on to the good advice in this video.
That's a good point about the screw extractor 👍
Thanks for the comment ;-)
Just snapped a 8mm 316 stainless bolt off, drilled it out to 6mm, stuck the easy out in and it snapped off flush. I watched 4 videos on removal options, purchased, drill bits, dremmel bits and spade type tile drills. They all broke. The only thing that worked was your tile drill bit. It seemed like it wasn't working after the initial sharpness wore off, so instead of going slow i just hammered it for 10 seconds at time, refreshing cutting fluid and it worked. Over all, 6 hrs of trying and failing, 30 mins of your method and success!! Thank you, one can stop swearing now.
Well done for being so persistent and not giving up 👏 👍
I've been doing this for years in my machine shop, it's painfully slow but it works without sacrificing an expensive carbide end mill.. it's especially useful on tiny taps
Thank you for the video. You are a true craftsman.
You are welcome
Thanks for the comment
I felt like I was watching a suspense movie. That was amazing that you just rolled with the flow and ended up victorious.
What a great set of methods you resorted to with each problem and the patience.
And I will say also, like the others, walking away from really stressful, critical problems really saves the day oftentimes. Take that break.
Jesus bless.
Wow, thank you!
Excellent video, as usual, very informative and to the point.

I wasn’t sure about using a drill bit made for ceramic tile but IT TOTALLY WORKED!! Nightmare over, thanks man!!
Great to hear!
This does work! I used a Milwaukee diamond hole saw bit to drill out a easy out that was broken off in an exhaust stud in the engine head. I took my time and used water to help lubricate it over and over. Eventually it came out and I was able to tap it and save the head.
Thanks for the comment 👍
Excellent video, thanks. Brilliant tips. I like the way you use the WD40 (or similar) to clean the hole and the tap. It's all these details that make your videos so useful.
Thanks for the comment, Mark ;-)
I've worked with a few very good fitters in my time, old school, hands on but you're on a different level. I don't know who your employer is or how much they pay you but it isn't enough.
I think the important thing to learn from this video is "don't break the tap/screw extractor"
Thanks, I've worked with some brilliant fitters over the last few years and I've learnt a lot from them, I still work with one of them now (he was 65 on Friday).
Thanks for the comment ;-)

Good information and I did not know about those little diamond tip hole saws I will be getting a set of those for sure! Any time you have unlike metals together like this I am not shy using anti_seize compound on the threaded bolt going into the aluminum its a practice that can save you a whole lot of time later on!
Thanks for sharing its very good information!
Thanks for the comment 👍
Really good tutorial and sound advice ...... I screwed my shoulder and arm up by not taking a break and getting stressed out drilling through glass ....... stress is a killer

the drill guide is brilliant. if not commercially available, you should market them. fascinating vids for an old wrenchbreaker to see from across the puddle.
Thanks, apparently you can buy something very similar called vent screws/bolts.

Left handed drill bits are also a good trick to use, they will usually spin the remains out when they grab.
🤔
Excellent Video as always!

Thanks for the tip with diamond drill bit
Didn't know that these exist.
I bought a 6mm and will try to drill out the broken drill bit from my car flywheel.
There is a hole to block the crankshaft from rotating and the drill broke off when i forgot to remove it and i turned the starter.
Now im changing the clutch and i want to remove the stuck piece in it.
It's amazing actually that some stone called diamond is harder than any hardest metal and it eats it like butter
Absolutely, it is amazing how hard diamond is!

You save my bike mate thank you!!!
Great to hear!
The removing a broken tap was very interesting. Very good tutorial. i hav'n't seen those diamond core drills but that is something I'm going to definitely look for online. For repair shops, it might be good to divide the number of times you can use a core drill by its cost, when working out a customer charge. Great work! I'm subscribed and following!!
The diamond coated hole saws are often used for drilling porcelain tiles.
