Hey Ave, new to your site and hopefully not too late with this suggestion. While I'm not familiar with rock drilling bits, these carbide buttons look very similar to rest pads we use in the jig & fixture trade. On occasion when finding pads broken along with their STUCK blind hole shanks, I'm able to "hydraulically jack" them out with grease. For this to work one usually finds the blind holes are drilled deeper than the shanks pressed in. If this is the case, one can drill and ream a "proportionally smaller" precision cross pin hole directly into the cavity below the shank. If successful, flush out and fill the cavity with grease making sure no air is trapped inside. Now SLIP in a precision fitting pin followed by a persuasive whack. If the hole size ratio is done right, this set-up works like a hydraulic bottle-jack and the shank is pushed back out. For this requirement I'm not sure it's worth the effort but properly applied it's been a lifesaver.
John M954 I used to use a similar technique to remove stuck bearings when I was a mechanic. Worked wonders on stuck pilot bearings/bushings, just fill full of grease and strike a drift punch into the hole. On badly stuck bearings, they would come out smoking and be too hot to touch.It was more reliable and faster than using the proper blind puller, but sometimes you would get a face full of grease lol.

You asking us how to get them out, I would have just blinked and said, well, I would ask you because your the smartest guy I know and If you can't get them out then they ain't supposed to come out.

4 year late fun acetylene fact! And easy way to remember. The two small common sizes are named for their original use as gas light fuel for headlights. MC ( what you had ) = Motor Car B ( plumbers torches ) = bus which had bigger/more lights
Having recently attempted the same thing, I thought I’d just gouge mine out with the oxy. This really didn’t work well. But as it happens after all my mucking around, a button had fallen out. Which leads me to assume, heating the bit with the buttons facing downward might be the go. Great video as always! Thanks
Massive fan of the channel, your knowledge of anything engineering is unparalleled. Just wanna say you should have flashbacks after the regulator and before the torch on your oxy-acetylene kit. I'm a fridgy and i've had an apprentice manage to blow his acetylene hose because he left his hose open to air for a few days, put it back together, lit his torch and was pretty much holding on to the end of a line of det-cord. Heard far too many horror stories to take risks with that shit. If electrons are angry pixies, acetylene is a divorced mother-in-law that you've pissed off at christmas dinner.
YES, many types of flux are made from wood sap. The electrical solder flux I use is essentially very light spruce sap. I am mildly allergic to spruce, so when that electrical flux hits the iron my sinuses go crazy and my eyes water, then I start to sneeze. We send a lot of tools out to have new carbide inserts & tips put onto the tool steel. Usually they drill or grind out the old tungsten then braze in new inserts or tips.
I drilled wells for years and we made some of our own tooling from old bits. HINT Never weld or cut on a carbide button bit. If there's a drop of water that managed to get under the button, the button will shoot out like a shotgun bullet. We'd run them too long sometimes and lose a button. If we didn't get it out of the well it would knock the buttons off every bit you put down there..
@@russelldodd93 Up until the seventies we used a coal forge made from a 55-gallon drum with an old Electrolux vacuum cleaner to provide air. We heated the bits up to just the right color and beat them to a chisel point and proper diameter sing a sledgehammer. Later we took to building up the bit with hardened welding rod when it got worn. The seventies brought carbide button bits that we only used in rock. They were disposable.
I used to manufacture rock bits - Sii Smith Tool. The sintered tungsten carbide inserts were press-fit using an interference fit of approximately -0.005 inches. As I recall, the pressure to insert was only 5,000 psi, and the pressure to extract was 50-tons. Test inserts had holes in them to cross-pin for laboratory testing. Typically, air is the cutting fluid not water when using this type of bit. It's primarily used for mining and blasting above the surface. Below surface mining uses an entirely different style of bit.. They typically only use water or "drilling mud" on oil and gas rigs, both onshore and offshore. The mud is a mixture of Barite, sand and water that raises the weight per gallon from 7-lbs/gal to as much as 15- to almost 20-lbs/gal. The heavyweight mud counteracts the downhole pressure thus preventing a "Gusher" (blow-out) like in the old movies.The mud is captured and recirculated until the raw crude shows on the "shaker table." Then they know they are in the pay zone. You are correct in the only way to get them out is cutting. Excessive heat will most likely damage the TC inserts. As a recyclable material, TC is very valuable, but too expensive to extract from the base material. Here is my contribution to the industry.

I have encountered a lovely green printing ink that smells EXACTLY like the vintage clove gum. Was so tempted to taste it . . . Probably carcino, but hey what isn't at high concentration. Glad to hear about vanilla welding rods, can't wait to try 😃
The dust from grinding those buttons will never come out of your lungs. Where I work, we have a bit repair shop, and the guys that work in there are full SCBA suited at all times when grinding/resurfacing bits.
I am no expert but my best guess for the vanilla smell is either cellulose or calcium carbonate, both commonly used in the flux. Depending on what you are using there could be other chemical that are unique to your brand, but most other chemicals in the flux are odorless.
Well I remember smelling vanilla when I bought my Gibson guitar and they use Nitrocellulose lacquer. So I'm betting the cellulose has a big part in it. Thanks for the info!
@@patricksworkshop6010 congratulations, it took four years for the first person to admit they didn't know how to use an oxy torch very well. 👏 when I posted this comment I worked for a drilling company and when things got slow or we were shut down waiting for parts ect we went thru old bits and removed the carbide buttons for salvage.....I could remove every button on that bit in 20 mins with ZERO damage to the buttons using only an oxy acetylene torch
@@cesarcalderon9180 i dont and unfortunately i dont drill any more so i dont have access to any used up bits. But the process is easy, keep your heat high (like REALLY high) and as soon as the steel starts to melt give it full 02 and keep the tip a good distance away. You only need the blow half the steel away and by doing it this way the steel melts away before the tungsten has time to reach its melting point. Oh and use the biggest tip you can find and throw out everything youve been told about your gauge settings....i never use my gauges at less than full blast....none of that 10 and 40 psi crap. When i need o2 it should be available not restricted by a predetermined pressure setting.
Just a thought. Given that tungsten carbide has a much higher melting point than steel, couldn't you just blast it with the oxy acetylene and melt away the steel around the TC? With a cutting flame it would take seconds and the TC would just fall out. Loved the commentary about the gormless shop assistants. We have lots of them here in the UK!
You are awesome! I've really enjoyed watching your videos. You're stuff is both funny and educational. And, you're a REAL guy who is humble enough to show your mistakes. But, man, you know your stuff!
Tungsten drill bit- button bit, never tried to remove buttons on purpose but I know from free tri-cone button bits get the steel surrounding buttons fairly hot then just hit the side with a hammer and drift, they are usually just press fit, had them fall out of a similar down hole hammer bit that had a shank, was building up shank, bit got hot, I dropped bit, and lost two of the tungsten buttons, might help in your quest for tungsten recovery
I really don't have any knowledge of what you're doing. I came across your video watching different forging video's. But I HAVE to comment how HILARIOUS you are! So funny, to the point I played it on our tv for my husband and we laughed so hard about you talking about the "pimple face fat kid with "my little pony eating a cheeseburger" tattoo! We are going to check out your video's, hopefully we will learn something and get a great laugh at your sense of humor! You're great! :) keep it coming!
Hey AvE, Love your channel! I'm sure you already know this but if you don't, Don't breathe the tungsten dust in. As a matter of fact, don't even create the dust, period. Very toxic. Anyway keep your stick on the ice!
Except for recreative use as a mean ballistic, what else can it be used for ? I mean, you more or less cant reshape it as far as I as of yet know. Is there a viable way to reshape it ?
As to your question about what to do with it... dose your country consider rail guns to be guns? Most countries don't know what to do with civilian owned rail guns yet.
I've turned a similar piece of tungsten carbide into a peening hammer. The carbide is so much harder than any steel that even with a light blow it deforms the metal easily.
Nevir202 I've had the hammer I made for a couple of years now and have put moderate use on it. It's still fine. You really don't need heavy blows at all to peen even hardened tool steel. I'm not sure exactly what the piece of carbide I used came from as I'm not the one that acquired it. I think it was a used spike from a heavy piece of excavating/construction equipment like a road grader or something similar..
pocoapoco2 Ah, probably a tooth off of an asphalt milling machine then... Never considered it as a hammer. I occasionally see the worn teeth lying around. Maybe I'll pick one up next time. Thanks for the idea. :-)
What could you possibly do with those? I for one thought the tips would be longer, but it kinda makes sense they are short like that, otherwise the tool would be even more expensive than it already is.
You can torch those things out... tungsten will stand up to your torch no problem, the steel will melt away.. I use a similar technique for removing helicoils and seized bolts. The difficult ones might be the stubs closer to the center. Still a oxy torch should work no problem!
If you're "reefing" the valve shut then you've likely damaged it and that's why it's leaking. You're not supposed to wrench them shut really hard. Just tighten them until they stop hard, no more.
What to do with the buttons... I seem to remember you were into gold recovery, you could make a rock tumbler that would produce very fine power with those buttons. You could probably tumble old computer parts as well which would be interesting in a kind of "I've made a horrible toxic mess" sort of way. Many moons ago both the wife and I were chemists and neither of us can think of an inorganic molecule that smells even vaguely of vanilla (I've also googled till I'm bored and didn't find anything). My best guess is that it's an organic binder for the flux, who knows they may even be putting vanillin in them to make them smell nice.
Well I just watched one episode and I think I am a fan lol. I'm going to toss out a big old guess that your Canadien haha. The mention of princesses autos tipped me off. Maybe Nord of Edmonton?? We're Flamers down here. I'm curious what are you going to do with the Tungsten and second just curious did you try freezing as a method? I'm looking forward to watching more!
+g0dbel0w If your talking about AVE he has the voice of a siren (Greek Mythology). Started listenin in and now have watched pretty much all of his videos...where has time gone! Pretty sure I needed to get to a meeting...about 2 years ago!
I knew someone that removed those for a living down in NM and they sold them off to a company that made TC powder probably by roll milling them against each other? to make various grades of sand paper, Personally I would love to see if smelting it into some tool grade of metal to make home made micrograin carbide stuff would be my suggestion or maybe a plating method to embed them, either way, Can TC be refined through electrolytically transmitting it like we do with copper through copper sulfate? some ideas I would try out lol.
I have been prepping to set up a couple things that use this tech, though don't want to air them publicly, lol, will message you if you want to talk. or even just know why not to talk publicly :)
Thank YOU! Hah..."Now what?" you asked. .. Awaiting a video of what you are doing with the button(s). I suppose you have gone off into another direction where the carbide pieces don't come into play. Anyway, I'm going to enjoy those videos also. :)
Sorry I might have missed you talking about what the rest of the drill bit is made from. But would it be possible to heat up the area around the buttons and hammer them out?
Heat the bit till red in a metal box. Which a of box is open as well as the top. Heat with propane weed burner till nice and red. Pull the bit from the box. Place on the ground and hit it with air hamm. Sharp chisel tip. Tungsten will cool faster than the iron. Hammer will rotate buttons out all on the ground. Did this for a couple years when I was a young man during the 70s. I you have any questions, just ask. Did 500 pound bits all day long. They were earth bits drilling for geothermal in cloverdale California.

i have been watching a few videos about tungsten carbide for research. one of the videos told me it's harmless unless you breathe the dust, so be real careful and wear a mask when using a grinder on it
The angle grinder seemed to be way less dramatic than I'd have thought; I figured the tool steel would have just eaten the wheels up. IIRC, you've a rotary tumbler? Unless they crumbled into dust, those would make for some fast milling. Their smooth rounded ends would make a sturdy tool for turning metal, and if they can take impacts (as their service in a drill bit suggests) they'd make a hell of a ball-peen hammer, being over twice as dense as iron, and much harder. If it were machined to have a shaft, grooves could be cut into the base and walls, to make a pretty solid high-speed grinding wheel, or rotary engraver.
Some guy uses liquid nitrogen. He drops them in there and then pounds it to powder. Then smelts it with iron, nickel and other stuff to make custom knives. Not sure how he does it or what heat but blacksmithing is an art.
Claude Rains What? Why? He put chunks of WC in his knives? Sounds weird I have a few knives with tungsten in them... begs the question how they were melted
A few years late, but I only just came across the video. Cut both end out a 35 gallon drum, lay flat, cover in sand, propane weed burner coupled with an oil drip and additional air supply, creates a through kiln in which you heat the entire bit to red, remove and sit in any makeshift stand and hit it with a 15lb jack hammer. All the tungsten almost instantly falls out, collect and sell.
What's the point of scavenging tungsten carbide? The only thing I've seen use for them is to use for cutting steals and such. If it's out of spec, what do you get from used TC? Is it worth money like gold for example? Sorry for my ignorance, but I have a lot of it at work, and would start collecting them if they're being thrown out. Thanks
I hate Air Liquide I work with compressed gas cylinders (lab/field calibration standards) and their customer service is worse than getting a handy J with sandpaper covered in salt while getting pepper sprayed in the face.
I once scrapped an entire 4 x 4 x 4 tote full of brand new tungsten carbide machining bits that were all still in the boxes. lol. Ended up getting a friend who owns a machine shop to come buy them all from the scrap yard for the price of scrap.
Wow, you guys are making something so simple very difficult. I have recovered the carbide compacts from thousands of tons of rock bits. Here's is all you have to do: heat the compacts and the area surrounding the compact cherry red. If you want to take the compacts out one at a time, just hit the red hot compact with some cool water. The compact will come right out. If you want to get all the compacts out as quickly as possible, make a small box furnace, use propane to heat the cones (in the case of a tri cone rock bit). Take them out of the furnace when they are red and hit the cone or tool with a large air hammer. The compacts will come right out.
I have a tungsten carbide wedding ring, its not been off my finger for 3 years and has no marks or scratches on it, despite working on cars / trucks etc.
Same here. I've probably done less wrench-turning than you have, but I've definitely whacked it against my share of otherwise-unforgiving surfaces and subjected it to many hand-washings with abrasive soap. Years later it's still flawless.
Funny fact about Tungsten wedding rings, when you have an injury/swelling on your hand and the paramedics have to get it off, they will ruin their ring cutter, because well, tungsten carbide. A simple way of solving this in an emergency situation is using locking pliers to break it a-part.
Dude, I worked for a bit shop in Farmington New Mexico 25 years ago. If I remember correctly I asked him htf he got those out and was told he heated them red hot (cone not the button) and would hit them with a sledge hammer to shock them out.
probably too late and someone has probably beaten me to it but, the flux creates ozone when you weld and thats the smell. its quite a pleasant smell which makes a change
We've got a little Top Hammer where I work that uses those flat hammer bits. We also have some 13.75" Sandvik Tricones that cost an eye watering amount of money. Always wanted to see if I could pull a button out of a used one for shits and giggles.
Hey do u know if those drill bit are worth anything I asked the scrap yard here an they didn't know I have a ass load of them I used to drill for blasting so just figured I'd ask
Since you had the torch out wouldn't it have been easier to just cut the carbide out? Maybe preheat with a rosebud or oven. Maybe you can melt them down in an plasma arc furnace and cast some pure WC bullets! Dunno what the cobalt would do at those temps though.
Depending on how much choochin' the grinder wheels had to do? Maybe drilling a whole on th outside ones and hammering them out might be cleaner lookin process ? But I have to try them both out first..lol..by the way...you FUCKIN' ROCK something fierce brothers.... You literally bring tears of love to my eyes...I'm in b.c. I know your voice...if I ever hear you ? I'm gonna have to shake those sausage fingers..lol..you will know it's me cuz I got a fkn blue fire ball logo of yours from boltr
could you drill a hole on the under side just enough to get in the opening under the carbide and tap a grease fitting in it and giver hell and the try heating the steel around the carbide ? just a thought
Get a very detailed Bridgeport mill tattoo and in a few years, when it inevitably goes blurry, add "focus ya fak" in a nice scroll.

@@patricksworkshop6010 congratulations, it took four years for the first person to admit they didn't know how to use an oxy torch very well. 👏 when I posted this comment I worked for a drilling company and when things got slow or we were shut down waiting for parts ect we went thru old bits and removed the carbide buttons for salvage.....I could remove every button on that bit in 20 mins with ZERO damage to the buttons using only an oxy acetylene torch
@@johnpike9612 do you have a video of that? Need to know how to do please!
@@cesarcalderon9180 i dont and unfortunately i dont drill any more so i dont have access to any used up bits. But the process is easy, keep your heat high (like REALLY high) and as soon as the steel starts to melt give it full 02 and keep the tip a good distance away. You only need the blow half the steel away and by doing it this way the steel melts away before the tungsten has time to reach its melting point. Oh and use the biggest tip you can find and throw out everything youve been told about your gauge settings....i never use my gauges at less than full blast....none of that 10 and 40 psi crap. When i need o2 it should be available not restricted by a predetermined pressure setting.
@@johnpike9612 we want mining drill bits scrap if you have so please let me know
I've been running my victors for 7 years plus now, you got some good regs
Just a thought. Given that tungsten carbide has a much higher melting point than steel, couldn't you just blast it with the oxy acetylene and melt away the steel around the TC? With a cutting flame it would take seconds and the TC would just fall out.
Loved the commentary about the gormless shop assistants. We have lots of them here in the UK!
I'm surprised you didn't grind them out first. Seems like the most straight forward and sure fire path.
Love the black snow falling thru the shot from when you started her up on straight kaboom juice.
This guy is like a mechanical super hero
You are awesome! I've really enjoyed watching your videos. You're stuff is both funny and educational. And, you're a REAL guy who is humble enough to show your mistakes. But, man, you know your stuff!
Tungsten drill bit- button bit, never tried to remove buttons on purpose but I know from free tri-cone button bits get the steel surrounding buttons fairly hot then just hit the side with a hammer and drift, they are usually just press fit, had them fall out of a similar down hole hammer bit that had a shank, was building up shank, bit got hot, I dropped bit, and lost two of the tungsten buttons, might help in your quest for tungsten recovery
I really don't have any knowledge of what you're doing. I came across your video watching different forging video's. But I HAVE to comment how HILARIOUS you are! So funny, to the point I played it on our tv for my husband and we laughed so hard about you talking about the "pimple face fat kid with "my little pony eating a cheeseburger" tattoo! We are going to check out your video's, hopefully we will learn something and get a great laugh at your sense of humor! You're great! :) keep it coming!
On the note of tungsten carbide, you can grind it to shape (but it eats up your grinding wheel) to an all purpose and very resilient tool
Hey AvE, Love your channel! I'm sure you already know this but if you don't, Don't breathe the tungsten dust in. As a matter of fact, don't even create the dust, period. Very toxic. Anyway keep your stick on the ice!
Except for recreative use as a mean ballistic, what else can it be used for ? I mean, you more or less cant reshape it as far as I as of yet know. Is there a viable way to reshape it ?
As to your question about what to do with it... dose your country consider rail guns to be guns? Most countries don't know what to do with civilian owned rail guns yet.
I've turned a similar piece of tungsten carbide into a peening hammer. The carbide is so much harder than any steel that even with a light blow it deforms the metal easily.
pocoapoco2 Sounds interesting. Ya've never had a problem with the carbide shattering as was seen here while whackin away with it?
Nevir202 I've had the hammer I made for a couple of years now and have put moderate use on it. It's still fine. You really don't need heavy blows at all to peen even hardened tool steel. I'm not sure exactly what the piece of carbide I used came from as I'm not the one that acquired it. I think it was a used spike from a heavy piece of excavating/construction equipment like a road grader or something similar..
pocoapoco2
Ah, probably a tooth off of an asphalt milling machine then... Never considered it as a hammer. I occasionally see the worn teeth lying around. Maybe I'll pick one up next time. Thanks for the idea. :-)
What could you possibly do with those? I for one thought the tips would be longer, but it kinda makes sense they are short like that, otherwise the tool would be even more expensive than it already is.
You can torch those things out... tungsten will stand up to your torch no problem, the steel will melt away.. I use a similar technique for removing helicoils and seized bolts. The difficult ones might be the stubs closer to the center. Still a oxy torch should work no problem!
If you're "reefing" the valve shut then you've likely damaged it and that's why it's leaking. You're not supposed to wrench them shut really hard. Just tighten them until they stop hard, no more.
Thanks for the video , do you mine me asking what you use the carbides for ? Anything cool . The reason I ask is , I have some bits around . Thanks
You should try carbon arc gouging to get them out. You can usually rent the equipment somewhere.
What to do with the buttons... I seem to remember you were into gold recovery, you could make a rock tumbler that would produce very fine power with those buttons. You could probably tumble old computer parts as well which would be interesting in a kind of "I've made a horrible toxic mess" sort of way.
Many moons ago both the wife and I were chemists and neither of us can think of an inorganic molecule that smells even vaguely of vanilla (I've also googled till I'm bored and didn't find anything). My best guess is that it's an organic binder for the flux, who knows they may even be putting vanillin in them to make them smell nice.
***** The wood they are using could very well be ponderosa pine which smells either like vanilla or butterscotch.
Well I just watched one episode and I think I am a fan lol. I'm going to toss out a big old guess that your Canadien haha. The mention of princesses autos tipped me off. Maybe Nord of Edmonton?? We're Flamers down here. I'm curious what are you going to do with the Tungsten and second just curious did you try freezing as a method? I'm looking forward to watching more!
This dude seriously enjoys listening to himself talk.
oh shiiiit
+AvE Im not sure if youre talking about yourself or g0dbel0w.
+g0dbel0w hell, 150,000 people like listening to him talk. thats kinda how the channel works.
+g0dbel0w If your talking about AVE he has the voice of a siren (Greek Mythology). Started listenin in and now have watched pretty much all of his videos...where has time gone! Pretty sure I needed to get to a meeting...about 2 years ago!
+AvE I know you are but what am i
did you try induction heating the base metal to release the tungsten carbide parts?
i didnt know u spoke french, i learn so much from uu
I knew someone that removed those for a living down in NM and they sold them off to a company that made TC powder probably by roll milling them against each other? to make various grades of sand paper, Personally I would love to see if smelting it into some tool grade of metal to make home made micrograin carbide stuff would be my suggestion or maybe a plating method to embed them, either way, Can TC be refined through electrolytically transmitting it like we do with copper through copper sulfate? some ideas I would try out lol.
I have been prepping to set up a couple things that use this tech, though don't want to air them publicly, lol, will message you if you want to talk. or even just know why not to talk publicly :)
I want to let you know you have quickly became my favorite UA-camr
Thank YOU! Hah..."Now what?" you asked. .. Awaiting a video of what you are doing with the button(s).
I suppose you have gone off into another direction where the carbide pieces don't come into play.
Anyway, I'm going to enjoy those videos also. :)
Sorry I might have missed you talking about what the rest of the drill bit is made from.
But would it be possible to heat up the area around the buttons and hammer them out?
Heat the bit till red in a metal box. Which a of box is open as well as the top.
Heat with propane weed burner till nice and red.
Pull the bit from the box. Place on the ground and hit it with air hamm. Sharp chisel tip.
Tungsten will cool faster than the iron. Hammer will rotate buttons out all on the ground.
Did this for a couple years when I was a young man during the 70s.
I you have any questions, just ask.
Did 500 pound bits all day long. They were earth bits drilling for geothermal in cloverdale California.
@ronballard 4910 selam bu yorumlarin neredeyse hepsini okudum ancak tecrubeli birinin yazdigini göremedim bu konuda deneyimli oldugunuz soylediniz gercekten bu tungsten uclarini takili oldugu yerden nasil cikartabilirim detayli yardimci olursanız sevinirim
i have been watching a few videos about tungsten carbide for research. one of the videos told me it's harmless unless you breathe the dust, so be real careful and wear a mask when using a grinder on it
Did you consider drilling from the backside and tapping them out with a rod?
The angle grinder seemed to be way less dramatic than I'd have thought; I figured the tool steel would have just eaten the wheels up.
IIRC, you've a rotary tumbler? Unless they crumbled into dust, those would make for some fast milling.
Their smooth rounded ends would make a sturdy tool for turning metal, and if they can take impacts (as their service in a drill bit suggests) they'd make a hell of a ball-peen hammer, being over twice as dense as iron, and much harder.
If it were machined to have a shaft, grooves could be cut into the base and walls, to make a pretty solid high-speed grinding wheel, or rotary engraver.
That up close torch flame looked like a frackin' Light Saber. 👍
I wonder the difference in carbide quality between those buttons and the teeth on the home-gamer circular saw blade. I'm assuming significant.
The best bit of this is listening to you talk - you are very funny!
I don't know what you're planning on doing with them, but I'm hoping it involves a DIY arc furnace to melt them down.
Some guy uses liquid nitrogen. He drops them in there and then pounds it to powder. Then smelts it with iron, nickel and other stuff to make custom knives. Not sure how he does it or what heat but blacksmithing is an art.
Claude Rains
What? Why?
He put chunks of WC in his knives? Sounds weird
I have a few knives with tungsten in them... begs the question how they were melted
VicariousReality7 I don't know. I'm not a blacksmith. Go find a master and ask him.
Oh man, you starting the welder reminds me so much of the f18's on my old carrier starting up. Good times :p
A few years late, but I only just came across the video.
Cut both end out a 35 gallon drum, lay flat, cover in sand, propane weed burner coupled with an oil drip and additional air supply, creates a through kiln in which you heat the entire bit to red, remove and sit in any makeshift stand and hit it with a 15lb jack hammer. All the tungsten almost instantly falls out, collect and sell.
they look to be around the size of a .45 caliber slug. You could make some T.C 45 caliber long colt rounds.
Noah Kuzel
TAOFLEDERMAUS has done it.
Wil Hobbs *he made them and sent them to jeff at tauflerdermaus
Ok I'm watching old videos.
Yeah I saw that video and the guy that shot them did a horrible job of balancing them out. Because they had a case of the weeble wobbles real bad.

love your Vid's man , 2 bad I'm jobless to help . keep on the good work
What's the point of scavenging tungsten carbide? The only thing I've seen use for them is to use for cutting steals and such. If it's out of spec, what do you get from used TC? Is it worth money like gold for example? Sorry for my ignorance, but I have a lot of it at work, and would start collecting them if they're being thrown out. Thanks
I hate Air Liquide
I work with compressed gas cylinders (lab/field calibration standards) and their customer service is worse than getting a handy J with sandpaper covered in salt while getting pepper sprayed in the face.
*****
You aren't kiddin'!
I once scrapped an entire 4 x 4 x 4 tote full of brand new tungsten carbide machining bits that were all still in the boxes. lol. Ended up getting a friend who owns a machine shop to come buy them all from the scrap yard for the price of scrap.
Could you melt them out? I mean, the TC has a crazy melting temperature, so everything around it should melt first no?
Wow, you guys are making something so simple very difficult. I have recovered the carbide compacts from thousands of tons of rock bits. Here's is all you have to do:
heat the compacts and the area surrounding the compact cherry red. If you want to take the compacts out one at a time, just hit the red hot compact with some cool water. The compact will come right out. If you want to get all the compacts out as quickly as possible, make a small box furnace, use propane to heat the cones (in the case of a tri cone rock bit). Take them out of the furnace when they are red and hit the cone or tool with a large air hammer. The compacts will come right out.
Hi.
Is it possible to send me a demonstration vidio clip to remove the tungsten ball or pellet from the mining drill bit.
I have a tungsten carbide wedding ring, its not been off my finger for 3 years and has no marks or scratches on it, despite working on cars / trucks etc.
Same here. I've probably done less wrench-turning than you have, but I've definitely whacked it against my share of otherwise-unforgiving surfaces and subjected it to many hand-washings with abrasive soap. Years later it's still flawless.
Funny fact about Tungsten wedding rings, when you have an injury/swelling on your hand and the paramedics have to get it off, they will ruin their ring cutter, because well, tungsten carbide. A simple way of solving this in an emergency situation is using locking pliers to break it a-part.
Just wondering what you did for a living your smart at mechanical shit and funny as hell. Love the vids
Dude, I worked for a bit shop in Farmington New Mexico 25 years ago. If I remember correctly I asked him htf he got those out and was told he heated them red hot (cone not the button) and would hit them with a sledge hammer to shock them out.
probably too late and someone has probably beaten me to it but, the flux creates ozone when you weld and thats the smell. its quite a pleasant smell which makes a change
is tungsten carbide actually worth anything? why do you want them for if not?
i support the insurance guy, this things are DANGEROUS
Mate, love ALL your videos and also your anonymity, keep them up! I like your different European accents, you should try American ones too!!!!!
We've got a little Top Hammer where I work that uses those flat hammer bits. We also have some 13.75" Sandvik Tricones that cost an eye watering amount of money. Always wanted to see if I could pull a button out of a used one for shits and giggles.
yep there organic compounds in the flux ive heard some are sap based as well as cellulose based
So Tungsten Carbide isn't so tough under tension. Sir you have contributed to the body of scientific knowledge.
How long did it take you to rip that carbide out with a grinder
I am not real technically savvy. but what makes these tungsten carbide buttons worth recovering ? Seems like its kind of a hassle.
Do this, get a Bridgeport with a core drill and drill it out steel material around the outside of the buttons. I've made thousands of these bits..
Hey do u know if those drill bit are worth anything I asked the scrap yard here an they didn't know I have a ass load of them I used to drill for blasting so just figured I'd ask
Since you had the torch out wouldn't it have been easier to just cut the carbide out? Maybe preheat with a rosebud or oven.
Maybe you can melt them down in an plasma arc furnace and cast some pure WC bullets! Dunno what the cobalt would do at those temps though.
Where is the guard on your grinder? You naughty naughty boy! :)
***** I used to say that but then I googled angle grinder accident :O :D
***** Wow. I just googled that too. Those are some UGLY wounds.
Love your tatoo suggestions
Did we ever do anything with those buttons??
Depending on how much choochin' the grinder wheels had to do? Maybe drilling a whole on th outside ones and hammering them out might be cleaner lookin process ? But I have to try them both out first..lol..by the way...you FUCKIN' ROCK something fierce brothers.... You literally bring tears of love to my eyes...I'm in b.c. I know your voice...if I ever hear you ? I'm gonna have to shake those sausage fingers..lol..you will know it's me cuz I got a fkn blue fire ball logo of yours from boltr
could you drill a hole on the under side just enough to get in the opening under the carbide and tap a grease fitting in it and giver hell and the try heating the steel around the carbide ? just a thought
What about using dry ice or liquid nitrogen? Metal shrink? Both bit and carbide???
Man, I love the commentary you do! "Herring choker" - LOL!
What if you hung it upside down and heated it with a torch, then shoot keyboard duster on the buttons, they may shrink out from the pressings.
I just subscribed after the amazing comments you made! awesome!
what is the metal golding the carbide? must be able to forge it out right?
If it's an interference fit ,and heating didn't work , what about cold , liquid nitrogen or what about dry ice , thermal contraction .......?
