This is my 200th vidja! Incredible how time flies, still having fun in the shop, still making lots of mistakes so you don't have to and still inspiring Trolls to lob spitballs from the know-it-all-do-nothing peanut gallery.
The matter at hand:
I bust a crappy tap and show how to get it out in the home workshop.
There are many more-or-less effective ways to remove a broken tap. This is the toughest situation, a broken tap in a blind hole. In a thru hole, you can go for the hammer and chisel brute force method.
Sometimes despite our best efforts to the contrary, things don't go according to plan, so we try something else. Surprisingly, that something else works better than the original plan.

Back in the early 80's, a friend of mine was a machinist and I had asked why he used Chinese taps. He said, have you ever tried to get a broken American tap out?
I don’t get it please help
@@kremit5084 American taps are usually high-quality, made out of tool steel typically, and hard as diamond. Getting one of those out using the methods in this video would be a nightmare.
LMAO!!!!
@@MFrawley I agree He does it wrong.
And i have removed a lot of taps in my days, i would not use his technique, maybe as a last resort.
First off always use a left hand flute drill when doing stuff like this and to be honest just tapp it out with a hammer and a chisel.
@@sopalen a left hand flute ( high speed steel) drill to drill out a high speed steel Chinese tap? You're having a laugh mate. Using a LH drill to drill out a broken bolt or stud yes but not something that's the same hardness as your drill lo

Thanks for the broken tap extraction tutorial. This has allowed me to not only remove a broken tap, but in rapid order allow me to break off a new one.
Just did that with a bolt extractor. Removing the second one has been an even larger chore.
When I break a tap at work usually use a ball endmill big enough to peck out the center. At home I just cuss at it for 12 hours till it's annoyed into vacating the hole.
As one of my old NCOs used to say, "I'm not prejudiced; I hate everyone."

That would rather fit with the Belgium language than Dutch.
I broke a tungsten carbide tap below the surface. I used cheap diamond-tipped Dremel bits to cut between the flutes of the tap and it came out easily. Just follow the precaution of cutting in 30 second intervals and allow for the bit to cool before going back in so the diamond tip doesn't overheat and separate from the shaft.
I had a German foreman who never gave a cheapo cutting tool to anyone. Bless that man.
Robert Clolery the price was high though, hope the counselling going well
Well I was mostly only given blunt tools.... yay beeing an apprentise.
Me : This nitrideded steel ususally I work with ceramic on it.
Boss : take this one
Me: its blunt and the edges have broken of
Boss: do it
Makes one hole the secound one the tap goes bust.
Me: I need something harder than the tap to drill it out. Can I have one of the tungsten carbide drills?
BossNo take this HSS one
Drill may as well be made from warm butter.
Me: Can I please have now the proper tool to get this tap out, for example this spark erosion device everyone here is using when a tap is broken?.
Boss: Try with this HSS+Co drill
Me: sigh
Drill goes bust.
Me: Now?
Boss. Sigh
Me : Gets the devise plugs it in and within ten minutes the hole goes through again.
Me: to Boss: Did you order some new taps as I have asked that has been the last one
Boss: No

As a tool and die machinist with 30 years experience, I have found it to be more practical when drilling out taps with carbide, to use a drill bit that is just under the size of the body of the tap. So that you drill a hole inside the body of the tap without breaking through the sidewalls. That way the tap remains one piece in shape and does not have much chance of breaking your drill bit. Then all it takes is a couple of taps with a punch and the pieces will fall out of the hole.
I do love this channel and fine that this guy has a wealth of knowledge and a sense of humor to match.
This is the way
Now that is how UA-cam videos should be. Good information, delivered in an easily watchable, irreverent and entertaining way. Well done sir, I just subscribed.

I work part time for a foreigner, we were talking about fixing something on a Sprinter van, and I said "there's more than one way to skin a cat", he said "what the F%@K does that's have to do with this,", ?? 😆😆
My old timer foreman once used a blow torch with the fine flame tip after warming it up to cherry glowing bright, he hit the oxygen lever at the exact perfect moment with the flame at a perfect angle and with accuracy and precision and blew away the broken tap from the hole with minimal collateral damage to the hole like magic.
This has aged so nicely
I don't know if this helps stop tap breaking, but when I trained with the R.A.F. in the 60's they taught us to always use a good cutting lubricant, (I think we used tallow then). Also once you have the tap well started you should wind forwards one turn, back half turn and then forwards again. This breaks the cut metal swart into short strips so they don't block the hole so much. For aluminium alloys, back out the tap frequently or the swarf will accumulate, re-melt in the hole and fuse or jam the tap. Also, use a taper tap to start and then a plug to finish. A broken tap should be very rare in your workshop especially if you are drilling the correct size hole. Sorry if you already know all this stuff, but I see a lot of youngsters who don't.
This guy taps
Im not an expert. Thats why im here to learn. But in this situation, wouldn't it be easier and much faster to simply drill a series of little holes into the tap, and then unbolt it with a flat blade tool?
vacomments what do you mean "unbolt it"?
It's difficult to drill into the material that the tap is made of

Rather stick to talking about getting out broken taps. Or more often broken screw extractors...
@@spettro9 The story about the dog was in Thailand...
I've adopted two feral dingo dogs from Taiwan over the last 15 years. They're actually really cool animals. Notably different from traditional Western domestic dogs. My first one was part lab and it was a cool mix with the dingo. He was the best dog I've ever met in my life. When he passed I had hundreds of people reach out to say how much they'd loved him. Dozens of whom I'd never even met. This was pre Instagram too, these were people that had met him in person while a friend was watching him and friends of my partner who'd met him while I was at work or gone for the day. My current one is a full blown dingo and almost acts more like a cat than a dog most of the time. She's very independent and not as social, but very sweet with the people she knows and trusts.
Glad to see the carbide bur work out here. Had the same issue at work trying to tap out an 8mm hole for a Timesert and snapped off almost exactly as what you were working with. Tried almost all the same tricks and the carbide bur was what finally got it out.
As a mashinist, mostly working CNC mills, I like to keep some used up carbide endmills handy.
You can use those on the drill press as demonstrated or write a quick little program (preferedly helical pocket, if your control allows for it, but drill pecking is ok too), to mill out the broken bit.
If they breake it's no problem, since they weren't good for anything else anyway.
I broke a tap in acid-proof stainless a couple of weeks ago, blind hole. I used a hammer, a sharpened center punch and some patience to extract it. Basically I just shattered the broken tap in the hole piece by piece with the punch
That's the way I do it. It's way quicker to punch it to shatter it and start over
I broke a tap in hardened steel,.. was not a cheap tap, best I had... Rushing using a drill to tap with, but hey, the 30 previous holes went great. Couldn't extract it so I melted the whole god damn thing with the welder and filled the f**king hole, ground it smooth and walked away. Decided I didn't need a threaded hole that badly.
Soft juicy bags of meat and guts 😂
@@justingrey6008 That's a reasonable solution. (sarcasm)
wait, if the stainless was acid-proof, couldn't have you used acid?
I use a ballnose carbide endmill and drill a hole through centre. Make hole big enough that it just fits inside of flutes that way there is no interrupted cut to break ballnose. Once you drill out middle a solid hit with a chisel or punch will cause tap to shatter. Blow out and retap. This also saves existing thread.
I learned this manly skill decades ago...I do find your presentation hilarious. I enjoy your stories and comments!
Shouldn't Step 0.5 have been to use a left-handed twist drill, followed by an EZ-Out? (Which is then followed by the video on how to remove an EZ-Out that has snapped off while trying to remove a tap...)
Nothing ever easy with a EZ-OUT!

Olivia Lambert he is talking about garbage stuff not race
I really enjoy your channel. Recently a neighbor came over with a broken easyout trying to remove a broken bolt from a casting. We wore out some drill bits, when I remembered I bought a Rodman 1/4” universal drill bit from a truck show. It cut like that carbide burr.
Great vids fun and informative. One trick i use with those pesky broken taps is to grab a dull solid carbide end mill . run it at about 500 rpm. And just plunge thru the center of the tap. The end mill will melt the tap on its way thru past the tip of the tap. You may want to start off center on larger taps to brake thru one of the webs. Then just pick the rest of the tap pieces out. Just another way to skin that cat.
Now.. show me how to do it by hand under a car, and make it a crooked easyout stuffed into a 1/4-20 bolt that's in an aluminum block.
I did it with 3 broken studs from a 5.4 f150 that was up north, everything was rusted out down there, but i removed 3 studs without removing the engine or head, from the fender well by tig welding
+Kirby Weldon- i'm a professional auto mechanic. Ive had to deal with stupid crap like that before. get those cheap ass diamond engraving bits from harbor freight. a couple bucks for 50 of them. put them in your dremel at lower speed and just burn through whatever you need. you'll get a few things out before you run out of bits and you'll save a shit load of time if you act like the bits cost nothing. which they don't.
+zzdfhgdhd hahahahhahahahaha
ChrisHallett83 my method of choice
Kirby Weldon buy a new car.
When i break a tap into steel, i heat it until it’s red hot with the oxyacetylene torch, let it cool down slowly to unharden the steel and once it’s cold, i drill through with a normal drill bit.
Smart man, think with ur head when you don’t have infinite tools and $
The proper term for "unharden" is "anneal."
You're welcome.
@@fubartotale3389 Ackchyually I would say this is normalising.
👍
Lmao, now that is a guy who's never tried it, trying to spread metallurgy knowledge as if it's a one size fits all solution. High speed steel can't be annealed in the same way as most tool steels. It's pretty much the defining feature of high speed steel that you can run it red hot and still not lose its temper, hence why it can cut mild steel like butter. Yes, it'll naturally dull faster when that hot, but it'll still be just as hard once cooled, unless you let it cool for literally days like how they anneal it professionally. Trust me, I've tried many times before...
Welder: just gouge it out and fill it in then lets go for lunch in 10 minutes.
It's all good as long as they don't perform ultrasonic inspection.
Due to youthful indiscretion there is right now, somewhere in the world, a piece of heavy machinery in operation that has a painted-over broken tap embedded in it.

A STORY that only fellow tradesmen would appreciate:
I began my career in 1972 at a trade school in upstate NY. I was sponsored by Alliance Mold Company (a branch of Alliance Tool and Die) so I had employment upon graduation.
I served apprenticeships in moldmaking and toolmaking. My first day on the job I was working for an older moldmaker direct from Germany. His name was Gunther Buetnagel, or something very Nazi sounding, and he had that strong German accent. To say that I was intimidated would be a gross understatement.
My first job was to take a mammoth ejector half (or, cover half...so many years later I forget which half got the waterlines) of a mold and hoist it to the equally mammoth radial drill. My assignment? To drill water lines. I soon discovered that this was the most dreaded job in all of Mold Making, and it was always given to first year apprentices.
Well, I had never operated a chain hoist before, and I had no idea on how to maneuver the hoist hook into the eye bolt on the mold base. And, no one told me that the chain hoist had an override! This meant that as you pushed the button to move the hoist with block attached the momentum of the moving block was too great for the hoist to stop instantly.
I found out the hard way. As I approached the radial drill I released the button but the block kept going. All that you saw were guys working in that area bailing out, and a huge block swinging from side to side,
Eventually a journeyman showed me how to do this safely and I got the block fastened to the radial drill. I had to drill these incredibly deep holes all along the outer edge of the block, and they all had to intersect...in other words you had better drill straight. Long drills liked to wonder, and it took experience to keep the drill in line.
Well, I had not yet developed this skill...I did not clear out the chips correctly as the flutes on the 3/4” diameter drill bit went below the surface. You guessed it. The drill bit broke deep into my first ever waterline!
Disaster. On my first day. This drill had to come out. A mold must have waterlines to keep the steel cool during production. Of course I had no idea how to do this. Worse yet, I had to find Mr. Buetnagel and give him the exciting news.
These old country moldmakers were hard ass. He told me to get that fucking metal out of the waterlines on his mold. And, not to bother him until all of the lines were in. “Now, leave me the fuck alone,” was his parting statement.
I was fortunate to get help from some 4th year apprentices who understood my sorry situation. But, after many tries we just could not free the bit from the hole. It was too deep (probably 8”), and impossible to break free. The engineers had to design a different system, which meant changes in dimensions and new blueprints.
You would think that after all of this that they would not let me anywhere near the block. It was not done like that back then. I was given instructions by Mr. Buetnagel not to bother him until the job was done. That meant getting back to the drilling!
Well, I did not bother him (he was well aware of what had happened) and I passed this obvious test of my character. I learned. I got all of the waterlines in. Even though it took me much, much too long. It was a part of the initiation as a first year apprentice.
The moral: I wish that we had you guys back then!
If you stick two drill bits in two opposing flute channels, you can usually walk those busted taps out with a crescent wrench on the two bits.
that's a novel idea sir
I'll be using that tip. Thanks brother
There is a special carbide spade drill made for drilling broken taps. The run at a real high speed. If you don't run them fast enough. They break apart. If it is going fast enough. It goes through like butter. It is best to run a full flood anytime you run carbide. But hard to have that in a home shop. I was a machinist for 37 years. I have had luck with the tap extract like you mentioned. But probably broke more of them then got them to work. We had one of the electro arc machine for removing taps in our shop. They buzz through a tap like you won't believe. One of the bosses in his infinite wisdom goes and surpluses it because it took up a 4 ft by ft space. I was like what the hell. He tells me no body ever uses that thing. I said the hell they don't. It gets used all the time. It is so fast guys are in and out of it in less then 10 minutes. They make sure they are so they don't have to answer to why they broke a tap off. We had EDM machines all in our shop across the street. He tells me if a tap gets broke we will send it and have them burn it out. If it was any sizable tap The Electro arc had a circuitry that just buzed through they thing. Faster then a drill could go though the hole to start with. It had flood coolant and a vibrating head also. The combination is what made it work so well. I was thinking you maybe should show how to tap the hole properly. Using the correct handle instead of a wrench. Backing the tap up to break the chip. Using a spring loaded center to keep the tap in proper alignment. Show some different style taps. Standard, gun, spiral, and form taps. If you have one show them how a tapping head works in a drill or milling machine. Or even show how to power tap on your milling machine.
When I was a college in uk they called it a spark eroder
We had one in the Navy we called it the disinigrater sounds like
The same thing you used
I agree with Bobby Harpoon. There’s some good learnin’ we still need from ya!
I just removed/ destroyed a pipe tap buried in a hole. thankfully it was a through hole. I grabbed a carbide rotary file (burr) with a very sharp cone or point profile. used a die grinder. immediate results and ripped it to shreds. pulled out the chips with a magnet on the end of a scriber
yeah, that's the last place I would use four flute tap, I will go for the spiral, gun if you will, type tap. I believe it works best because it cuts one side of the "V" instead of both sides, like when you cut a male thread on a lathe.
I really like the audio in this format. The compression and delayed echo. I miss it in the new videos.
Tap extractor!!! Like most tools, you need practice using them and need the right size to get good results using them. I've successfully used them for retrieving a broken #6-32 up to a 1/2-13 taps. Start by blowing as many chips out of the hole as possible then add oil or cutting fluid. Make sure you can get the get the extractor rods down through the flutes. (spiral flute you're SOL) Next slide the collar down as close to the break as possible. GENTLY coax the broken tap back and forward until it willingly backs out with little effort. Most of the machinists I've helped out never saw a tap extractor before.
Look at you AvE!!! 6 years later and you saved my ass!!!

@ARMOND WILLINGHAM LMAO
So is mine! And both are crappy chineeseum tappy's as well
The only 1st, 2nd & 3rd TAPPING RULES I'VE EVER USED AND I HAVE NEVER BROKE A TAP....
#1 Always use a tapping fluid, of WD-40/Seafoam Deep Creep/PB Blast in a pinch.
#2 If you're tapping any metals, always cut 1/4 to a 1/2 rotation of the tap and then GO IN REVERSE AND BACK OUT THE TAP 1 TO 1-1/2 TURNS.
This "clears" the chips that can and will become jammed between the tap and the threads that you just cut, in the same hole.
After backing the tap out, hen proceed cutting more of the threads, repeat the reversing step every 1/4 to 1 rotation, depending how much resistance you feel from the die and how difficult it is to turn.
It's this resistance that eventually causes the tap to snap!
#3 Always make sure your Tap and/or the die you are using IS SQUARE TO THE HOLE, or shaft you want to cut threads on. If it is not square, the deeper you go, the greater the chance you have of "locking up' the tap and snapping it's bitch-ass in half!!!
Just crash landed on this channel!! Comepletely refreshing listening and watching!! Keep up the wizardry and shanagians,Im pickin up whatya lay'n down! Good stuff!!
One thing good about the Chinese taps is, if you look carefully you can see the metal beginning to deform or twist just prior to the tap breaking. This is your warning to stop, back out the tap, flush the hole and pray, as you start trying it again. Sometimes I have had to stop and back out the tap a little about a dozen times in one hole before I completed the tap. You call the Chinese taps cheap when they are really just sensitive.
Speaking of calling the Chinese names. A Chinese couple, The Wongs, moved to the US about a year before the couple's daughter was born. Something strange happened when the baby was born though. The baby girl was very dark complected. So, what did the Chinese man name his daughter?
Answer: Som Ting Wong.

I worked with an incredibly good but also
incredibly alcoolic old machinist.Anyway
once I broken a tap in a 2x2 inch by 3 ft
long piece of mild steel.After looking at
the thing,he proceeded to smack the
thing around at various hard targets to
eventually vibrate the little tap out of
its hole.It worked.
I have used the tap removal tools and had some success with them, but they are expensive and not easily available. I usually try needle nose pliers and try to see if I can get any movement out of the tap. If it moves I use air to blow out the little chips as I work the broken portion back and forth. This works pretty well. The few times both failed and I had to get schooled from a guy who had many more years experience working in much worse environments then myself. He taught me if the tap breaks off in a cast block you can heat it with a torch and the tap will melt before the block will. That is a last ditched effort for me but with his years of experience makes it look easy, he took the time to show me how to do it. It takes me much longer then it did him but its one of those things that you don't get a second chance with if you melt the block.
A broken tap in a large heat sink like that one...just use a low acetylene torch flame and heat 'just the broken tap' to 'cherry red'...next & quickly...turn the acetylene off and hit the cherry red broken tap with full force oxygen from the torch...oh yeah, don't stand in front of it because it will come out of the hole like a volcano. Old School methods still work. Clean up the partially tapped hole and do it right the next time.
Wow, does that really work!? Great tip, hopefully I remember it!
The machinists at the ship yard I did finish carpentry for did that.. seen it at least twice. Does work
That is a great idea. Just the thing for when you're working in an isolated area, like outback Australia,with no access to a spark eroder, but having oxy acetylene equipment.
Always keeping an eye out for diff tricks so thanks for that..
Yip!
I had a similar problem (wasn't a tap though, was an ez-out snapped off in a broken sparkplug stuck in my cars engine heads) I had no idea about the drillbits you used for this (and the ez-out was hard enough that cobalt ones did nothing), so I actually used a small 8mm diamond tipped holesaw (like you use for tile). Worked pretty good actually.
There is an old gunsmiths' trick to broken taps, two of them, actually. The first is to get carbon steel ones, but good ones. There is one American company still making them, you can get them through Brownel's. The carbon steel taps are much more brittle than HSS, so you put a punch on the tap and give it a good wack and the tap will shatter into a million pieces, allowing you to fish them all out. The second is to grind a notch on the shank so that it breaks on the shank rather than in the teeth, giving you something to grab. Bonus: just buy a new tap for every project. I am aware of one gunsmith shop that charges the customer for a new tap if one is needed for that service. They are cheap compared to wasting your time getting a broken one out.
Just came across this. Damn awesomely hysterical! Very refreshing to watch/listen to someone actually out in the field! I'm hooked.
I've never had a broken tap I couldn't remove by shattering the tap with a punch, hammer and magnet. And, every tap I've broken was preceded by a boneheaded move of either not keeping the flutes clear, side loading because of some awkward position (maybe not boneheaded, unavoidable) or drilling a fastener off center and leaving behind pieces to dislodge and jam up the tap.
I dated this Thai girl and she had a great sense of humor, here in the USA... We were at the Marina one day walking towards the filet table and she said, "Hide the fish-here comes an asian girl." Dang I miss her....
You shouldn’t have eaten her!!! LOL!!!
I want to hang out and drink beer with this guy just go hear his stories and his funny little sayings haha. But also this video was actually helpful! Thanks!
Many years ago, I broke a tap off in an engine head just trying to clean the threads in the hole. Took the head to an EDM shop and they extracted the tap (burned it out) leafing the threads in the head clean as a whistle. Best $20 I ever spent!!!
my god this guy has one hell of a man card,
shit!
+motorcity Mayhem engineer card , a bit different
fear no machine, master all your allowed
this year is a water well machine that does 1000 feet
in solid rock, with a air hammer wholly duck commander
the air pack has 900cfm at 300 psi.
all that while im learning buck transformers and building the cat motor
for the deck
and A ve astounds me, engineer cards, they just are not human
+motorcity Mayhem real men do not require cards
real men have spare cards
real men don't need ANY cards to figure out if their a man... depending on a card keeps you being a man.
spoken like a cardless woman
Neat! First time I saw anyone use a burr in a mill haha.
Thanks for taking a little extra time to insult my language.
And Dutch is not a throat disease it's a mouth dysfunction.
I watch this Chanel because I've been a machinist for 41 years and I'm still learning stuff.
left hand drill bit (Snap-on) has often worked for me while following the same procedure.
Always a pleasure watching your videos. Keep up the good work.
I genuinely appreciate that you volume adjusted for the drilling during your editing. Was watching while I was at work, so I was worried that it would be too loud to watch without disrupting my office mates.
That burr bit works dam well nice. I had one broken off. In the back of a platen. On a plactic injection molding machine. That was the best thing I found. Took my 90* air grinder. Half a work day later. Cleaned out the threads. And, the 1 1/2 hour job was complete.
When drilling with carbide: not only does the lubricant reduce the heat by burning off - which will make the bit last longer - but the lubricant also helps the chip flow away from the cutting surfaces which will keep the bit from chipping it's cutting surfaces off when it otherwise is forced to bite chip plus material. It's a general rule in life: _"There's always time for lubricant."_ Holds just as true in machining.
Needle nose pliers in opposing flutes and then vice grips on the jaws of the pliers and back up the tap. sometimes works.
There's no opposing flutes on a three flute tap.... and my needle noses are far too precious for that job!
Physics and vice grips have gotten me out of many a bind!!
Whenever I break a tap, I immediately hook up the air chisel with a tapered punch and angrily beat the $h!t out of the remaining tap pieces. Haven't run into an hss tap I can't destroy. Stumbled across this video while looking for the punch attachment thinking there may be a better way - not in my case - obliterated another tap while watching this video thinking about all the time I drilled through hardened steel with a masonry bit when I could have used a carbide burr.
Thank you for making it clear to the foggy. I stand with you on your thoughts. I love fact-based off of real results.
Stuffed 4 welding rods between the flutes and grabbed the whole shebang with vice-gripes. Actually worked AND, I ended up with art work ta-boot!
I know Carbide Burrs work extremly well. I had a broken easy out that no drill bits would touch. I got a carbide burr for my dremel and it chewed up that broken eazy out like it was nothing. It only took a few minutes and it was gone.
I would have just gone for the carbide burr in the first place, they always work for me.
I always keep the burr flooded with coolant though.
what head type did you used? round or flat?
Back in my fitting and machining days I would remove broken taps by getting a piece of thin flat bar - drilling a hole in the end smaller diameter that the tap and then mig weld the flat bar to the tap though the hole and use the flat bar as a spanner - it even helped if part of the tap was still protruding the hole
I had a real problem where you manufactured yours. I was using a quality tap that fractured and would not come out with a tap remover, so I used a hardened punch and shattered the broken tap, surprisingly it saved me time and money. Sometimes brute force works best.
Most job shops keep a supply of reground carbide ball end mills around, much better than using a drill bit on broken taps. Coolant does help but your air is better, as you peck use the air and give the hole a shot now and then to keep the small bits and pieces out of the hole.
YOU just name dropped yourself...
"MR.chris"
never knew your name
he said mr.christ
Power tool advice and good old family racism lmfao 😂 its like doing my apprenticeship all over again!! Much love big man lol
10:58 “why that was in my toolbox, I don’t know.” *CLANG* 2 points
I have had to remove more broken taps than I would have wanted to. I never found drilling worked very well, the break would almost always fracture the remaining tap and as you started drilling the fragments would break free, jam the drill and break that as well. Our solution to anything bigger than 16mm was a home made punch with a tough carbide insert (generally a trigon shape) brazed onto a rod and just bash the remaining section into crumbs. This used the taps brittleness against it. Then re-tap the hole and keep going.
This works. Just hammer them with a punch or so, hard metals like taps break easily. I have even managed to removed a 6mm tap in this way.
4 tanged tap removers: I've tried them many times, mostly because we had every size known to mankind in the tool crib at work, and all new, too! I never got them to work on any broken tap, that I couldn't have otherwise simply removed with needle nose pliers. Great tutorial!
I wonder if you can get one designed to go in a (manual) impact driver, that'd probably do it
When I was an apprentice, I snapped a spiral tap deep down in a blind hole, and the way I ended up getting it out was heating it up for awhile with the oxy and pouring oil down it and then smashing it to bits with a punch (went through quite a lot of punches)
a sharp cone profile carbide rotary file in a die grinder seems to work best for me in extreme rescues. I cut through the flutes to release the tap and then chisel it out if possible. I pull the chips out with a scriber magnet. very effective method so far.
anyone who has delt with a broken tap must agree with buying a quality tap to begin with! AMEN brother!
I used to wear my wedding ring at work too. Until the night I saw a coworker's degloved finger. Some sights you cannot un-see.
Stop discriminating!!!
We need some Korean Slurs :)
something something roof kroeans.
History is a great deal messier than these videos.
i dont understand this, but remember the golden rule, unless a country has won a war on its own then its not allowed to gloat, falklands.....
+Jamie Smith
Man, Rooftop Koreans isn't a slur; it's a proud moment in Korean American, if not Asian American history.
what have they ever won ? :p
This (5 years later ) is the best ive ever seen ever
Talking with your hands! Priceless
Tap extractors do work, you have to get the extractor right up against the broken tap, and use lots of lube. Twist back and forth a bit, then slowly work the broken tap out.
You got a good, genuine laugh out of me with the "China is a country, not a race"bit. A sub too.
First ever video I ever saw, like 4 years ago. Most the stuff you do I have no idea what the hell is going on! But here I am 4 years later still watching you're videos,
That was pretty awesome, doesn't happen often but when it does it's great to have some alternate plans
I'm surprised you didn't use a left handed drill bit!?..and a center drill.
Fellow journeyman machinist here!
I just use a pencil/micro grinder with the carbide grinding end. Mainly for apex bits (hard as frig) stuck in titanium bolts/screws. It also works just as well on taps that people break off because they don't break the chip and go to hard to fast. Also, people don't know how to use a tap most of the time.
When I was a young machinist I broke a tap on a job. The shop owner just put on safety glasses and beat the heck out of the tap with a hammer and punch to get it to shatter. He had it out in no time. I never saw anyone else try that. BTW I never knew taps were soft enough to drill with carbide. I did not expect that.
In case you've never tried "Ball Buster" or Relsom diamond core cutter bits from StrongArm, they're worth having a few in your arsenal. They are specificish to safe drilling but holy shit will they twist up a shirt. The ball busters are glorified rasps made for cutting ball bearings and the diamond cores are made for Relsom metal hard plate in old Hamilton, Mosler and probably other safes. Great twisty sticks!
Sometimes a needle nose that can be used as a spanner in the holes.
