- The cemented carbide that Sandvik Coromant uses comes from our customers, who make revenue by selling us their worn inserts and round tools.
Regardless of origin, we purchase the tools at the going market price.
We leave recycling bins at your premises. You fill the bins. We retrieve them with certified green transports. You bill us.

I love the thought that even after the cutting edge is completely gone the tool is still quite valuable.
Yes, and if really though about how far, small private manufactures might go for savings, with the right modifications of the machi e tool, like 3 d additive laser 're building of cutting edges, and coating, and sharpening grinding, all at a workstation 😎
As a hobbyist, even blunt inserts are valuable already. You can easily sharpen them on a diamond wheel and use them again and again.
The metal value is still there. The reason old milling machines will always be quite expensive is also because they have such a high metal scrap value. Sucks for a hobbyist trying to buy an old machine because even something from the 60s still costs a few thousand. Compared to a car which is mostly very thin sheet and needs a lot of refining to recycle you can buy for a few hundred and still drive for a few years.
@@excitedbox5705 On a plus side that metal value will not go anywhere and will still be there when the machine becomes scrap even for you. It's a deposit, not a cost.
@@aleksandersuur9475 I know but it is a big investment to make for a hobbyist. Almost better to buy a modern lighter weight machine for the same price and get the modern features and capabilities such as high speed spindles. An old bridgeport costs me more than importing a mill from China of the same size. An old milling machine from 2000 costs as much as an entry VMC or CNC lathe.
I'm a factory worker here in Minnesota. I asked my head tool room attendant a few years back how much my immediate department gets back per year just for recycling scrapped carbide tooling. He pulled up the spreadsheet, it's around $60,000.00 per year. Nothing to sneeze at!
You can sneeze at it it's ok.
Wow I can’t imagine what you spend on carbide tooling then if you are getting back 60k in recycling value!
@@georgeowen2083 If they used uncoated plates and resharpened them after blunting, they would save even more.
@@Freekniggers thank you
Bravo! Recycling makes sense to companies when the see $$$ coming back to them.
Back in the 70s they just got thrown in the swarf bin, recycling has come a long way in fifty years.
Imagine now all that cobalt, pricy as gold for EV materials and chemistry in general

Brilliant !!!! All those little inserts represent a massive amount of work being done already, Mind boggling.
Off topic but relevant
Look at how many telephone poles there a tree e on your next drive. Two people per ple installed them, I know cause I'm a sparky that has..
Its mind blowing to see such high numbers. Count them. Itsbits, just like carbide ,
This is why I love Sandvik. Not only do they make the best tools ever, they also care about the environment.
Cool! I've been looking forward to this video since I saw the "how inserts are made" video.
Thanks for uploading!
Stefs Engineering I use their products at my job. They are very good with their customers, they’ve sent reps to our plant to answer any major issues we had to deal with. And no I don’t work “for” them. Just wanna clear that up. Lol
We love Sandvik tools! Recycling is awesome. Thank you. Go Sandvik!
You make 'em
I'll break 'em
Haha yup
Lol
fishingfool211 try to break tungsten carbide tool bit with your hands or teeth.
@@shenghan9385 makes for delicious candy
mackk123 lol. It maybe delicious. You just have to be careful chewing it. Don't break your teeth.
Nice to see people have learned to recycle the material from used/broken cutting tools, helps the environment and the budget.
Makes a lot of sense considering the prospecting/mining/processing/raw material/enduser route. Great work SANDVIK.CORMANT!
Wow! I am amazed on how many machining cutting tools are recyled. I didnt know this method. You are awesome!
Thank you for recycling such a valuable product!
This video came up on my recommendation last night, and this morning two boxes of “SANDVIK” souvenirs are on my manager’s desk, if not by coincident, this is some impressive coordinated marketing.
Nice. Now i can scrap more stuff. This is a plus since its such a strong material that has built up all over.
This is great. I always thought that once a tool could no longer be sharpened, it could never be used again.
Metal is metal. You can always recycle it. They are just refining it into the starting materials.
should be some Icon for showing some love for Sandvik
Beautiful work. Please keep recycling. It is well worth it.
Wow, good to see. These numbers are amazing. I'd like to see the actual process, too.
Thanks for the video!
Its not easy to find genuine carbide tools off the shelf!
Your processing of cobalt is also a contribution towards good tool crafting!
I love learning all the different aspects of my career. Thank you for making these.
Thank you for your comment! Glad you enjoy our videos! Here you can learn a bit about vibration damping: th-cam.com/video/VCxm3vTWgvU/w-d-xo.html
The sound of a pile of tungsten carbide flowing down a belt is surprisingly beautiful.
But pure Wolfram is also very nice, even without the carbide compound.
Fantastic!With respect from Russia
I don't understand why this was never done from the start. Such a good way to recycle and save money on new materials
Very nice. What is the primary machine used for breaking down the material from solid into the milled/crushed powder? I think that's what most people were hoping to see. The chemical process is a given considering that's how just about every mined ore gets processed. I think we were all hoping to see some crazy machine that breaks the tooling bits down.
M Hamma from what I’ve heard they use a grinder with tungsten carbide inserts. Presumably they would be ball shaped like the ones seen on mining and boring equipment. It would make sense as they can make their own tooling, too.
There made be trade secrets in that process. By developing their own method, they might be able to do something more profitable than methods used by other companies.
@@bunnythekid I don't think a grinder would work? I would rather go for a crusher, an impact crusher or a roller crusher.
Dominiek Demaerel Tungsten Carbide would be really hard to crush. It has great compressive strength.
One way to recycle TC, which i only recently learned about, is reacting it with zinc in a furnace. The tungsten carbide swells and becomes porous. It can then be milled back into a powder.
@@bunnythekid Tungsten Carbide is realy hard, that makes it realy easy to crush. Take a normal hammer and smash a tungsten carbide insert, it will shatter into tiny pieces.
Nice job! Recycle everything!!
My prayer was heard. I was wishing for an insight into the recycling process since the hiw inserts are made Video.
1AB09CC3 insight is the correct word. Doesn’t really show much how tho.
Excellent recycling, I hope that for a long time we will manage not to plunder the planet 👏
NICE WORK SANDVIK. 😀😀😀😀😀
Wolfram is a Beautiful Element :3 .
Amazing, I've allways thought that tungsten carbide was a finals state and that it couldn't be broken down again to its original materials, I thought it had to be used like a kind of matrix material in either tools or abrasives
i used sandvig tips in my work place 40 years ago ! the try blade tip was a good improvment to hss steel tools .
and cobolt steel tools but we had a fix for the try tip wear we used to re shapen them on a diamond wet stone '
i have fogot the exact angle's we used to recut the tip's to but it was not the same as they came in the box / sheet .
needless to say we honed the the tips for the best perfomance for the metal we were cutting .
Would love to check there dumpster for the home mechanic/machinists im sure there would still be some useful tools
Did not know that Sigourney Weaver has a Job at Sandvik now.
It was her older sister Zackourney Weaver :D
Awesome!
Gees, we sell our carbides to a company that crushes it into small pieces and then sells it for shrapnel in grenades and ammunition. Also used to hard face earthmoving ground engagement tools and grouser pads. Cost to much to ship o/s because of the density.
Carbide shrapnel grenades sounds sexy AF.
I had been saving all and any worn out cutting bits for many years, I keep stuff like this for when times are lean ... COVID made it the time .. I was very plesantly surprised at the amount of cash i got for just 25 pounds of used bits!! :)
How much is the scrap price?
@@TheSoundOfTwang It's like the stock market prices change daily ... you have to look it up locally
Germany is such an awesome, mature country
Is that scrap dangerous material ?
Got about 35-40kg new carbide inserts. And some high speed Steel. Just need a metal lathe and a milling machine so I can use them. Got them from a old workshop were the owner and only employee had died
Awesome
Used parts looks like new in my opinion. Its can work more and more hrs
What is the mean percentage of tungsten, (tungsten concentrate) in carbide the world over? I bet I varies widly, I wonder if better inserts could be made by fusing molybdenum and wolfram, before producing the carbide
Amazing
I need more info on this, as we can supply used Carbide Tips for recycling. Let me know what type / grade Carbide Tips you accept. Whom should I contact here in India? Thanks.
Whats cool is the carbide bit you have right now might have a little bit of another carbide bit you returned to them.
You need to tell your XRF vendor to update their software. Windows CE??
Sandvik is excellent
Does all the tungsten carbide consistency is of same grade or they are of different grade?
They are all of different grades. Sandvik offers more than 220 finished products grades.
I saw Stefan Gotteswinter in the background being handcuffed and taken away for breaking into the factory?
Lmao what
It would have been nice if they gave us a tip on how/where to recycle carbide.
what do you guys do about PCD/CBN?
Brilliant but how do you get the different grades??? I use the gold coated 1020 grade. The best carbide I've ever used in the WCMX inserts. I made a video to compare it against H13A which was the best before. Look on my channel for the video.
userwl2850 This has nothing to do with the manufacture of the inserts, its how the individual chemicals are recovered. All the individual chemicals (tungsten cobalt etc) are separated and then recombine in different ratios to produce the inserts.
Good
2:37 this guy just broke the #1 rule of forklift safety lmfao
Could have been an initial lift off a stack with limited access, given the height it started at. Perhaps he should have backed up, lowered the load, taken another stab at it to bring the load closer to the back plate but...
Why don't they cut larger used inserts into smaller ones instead of breaking them down to powder?
👍👍👍👍👍
cool
I have 22 kg tungsten block. 75% purity. But I can't find any buyer in my country for this particular item. Where can I sell it.
super👍👍👍👍👍👍👍
nice wokr
Dr. Andreas Bock could use a tungsten carbide tooth.
0:38 - Omg! I can use 90% of those for DIY tools in my shop. How about selling such scrap as unmarked under unnamed brand for such purpose?
I've been in industry for over thirty years, and it still amazes me how many companies just throw out dull tooling, be it HSS or carbide. And even in shop's where employees are supposed to save used tooling to be recycled, they just toss it, often with the attitude of "Not my company".
That is a sad attitude, as sending back the tools for recycling is not just about the company - it is about saving the Earth´s resources which we all know are not infinite.
I want to sale tungsten carbide scrap .
2:40 He looks like the sane twin of Mr. Bean
I thought the same thing, cheers from John, Australia.
I want carbaet yg6 tips
Why we can sand them again to bring them in right cutting edge again?
Hi! If you are talking about solid round tools you can regrind them up to 3 times using our Reconditioning service. You find more info on the topic here; www.sandvik.coromant.com/reconditioning
I don't imagine how heavy an barril full of tungsten carbide would be
🖤
Хмм, как измельчают напайки?
Hi, we need a inserts of sandvik coramant 4330M-PM
I think you should have produce carbide tooling and insert that will unable to wear out and use for life time.
had no idea such things could be recycled, i all ways just through away.
I wants to make this type of plant in india fully linked with your company .
Kira2 harga limbah carbait kg beparah saya ada soal nya
Seems like this is only cost effective for large commercial machine shops to send their used carbide back for recycling, as a home hobbyist who goes through 2 or 3 carbide bits a year, looks like trashing them is still the only option.
Kevin L I'm assuming you go to the scrap yard already. Just bring your carbide with.
Hi,
Sandvik Coromant is committed to provide different types of packaging for our buy-back program and a small container for the collection of used carbide is available from our website. The small container can be used internally and can be placed at the end of the production line or on a desk.
For efficiency purposes, we ask customers to transport the buy-back materials using our 20KG packaging. Currently, there is no smaller packaging. For customers who want to return smaller volumes they may be able to do this via their local distributors.
Best regards
Jason Purcell
Global Services Manager
Bring them to a local machine shop that DOES recycle, or a tool supplier that will collect them for recycling.
Recycled carbide inserts has less quality in compare to fabricated from pure materials?
No. We have worked with recycled material in our production for years, and you can trust that the inserts have the same performance as if we would use virgin material only.
can any of the sandvik coromant officials contact me please? im also from the middle european part and i have a lot of tungsten scrap to recycle
Ulrika is a hottie!
"dissolve in liquid" of course, why am I not think about it? my hand planted on my face right now. duh my mistake, hey btw nice explanation video
How many times can carbide be recycled before it’s no longer useable for cutting tools? And at that point what happens to it? Would it then be discarded or recyled into something not requiring the material properties of milling cutters? Say ball point pen balls.
P0tat07 Infinite. Material properties don't change. You do lose a bit of the tungsten each time, so after hundreds of processing cycles eventually no tungsten will be left.
Hi,
Carbide can be recycled as long as it contains tungsten. Since we use a chemical process, it doesn´t matter how many time it is recycled. It is mixed with other material and can as new tungsten carbide be used for all applications as well as cutting tools.
P0tat07 they can be recycled forever. Because they are broken down to the constituent materials like tungsten and cobalt. And so called carbide is just carbon.
@@sandvikcoromant hello sir
me irani turning i love cut ing tools sandvik orginal 💖
Dr Andreas is Mr. Bean
Carbide can be crushed and will fracture into smaller pieces.
El boy thing I came for was to see it being crushed. I imagine Its just a hammer mill
Which is stamming from our own mine... wahrscheinlich sagt man das so, wa?
Prauder deutschman
Their accents make me think movie villain for some reason
That skeleton rattled about everything but the recycling. If I title a vid as "How to do something", it should show how I do that and how it should be done. We all knew why companies recycling everything they can, personally I was curious about how carbide tools get powdered. But despite the title, it was only an advertisement, which I didn't even want to see.
Hi I'm from India i would like to supply you tungsten carbide scrap
Like insert, end piece, sludge.
Just contact a local or regional Sandvik sales rep. They can set up up with the collection boxes and buckets. Typically, Sandvik will pay a better price compared with other scrap vendors since they are the end user of the returned material. Go to their website and find a sales guy in your area.
Dan Sammons
Thank you
Ill try to contact them.
Why isn't new cutting edges made on existing tools?
endmills are grindable but after some regrinding they start developing small cracks because of material fatigue. With inserts it could mess up their properties since they would become thinner. Another problem is the coating.
If you're interested you can look up the Swiss manufacturer Fraisa. They offer you a Toolcare service where you buy their mills and after using them you can send them back. At their factory they get decoated, grinded down a little and then recoated.
@@jannpatrick6392 Thanks. :)
grinding takes away material so the insert is no longer the same size
in cnc every insert has to be exactly the same or there will be size differences in the workpiece
@@janvanruth3485 yeah, but you could compensate for that with tool correction. But it's way better to just have all the same size. I guess that grinded inserts would be twice or more the price of sintered inserts.
@steve gale in my company we experienced this mr. genius... And yes, i'm no engineer yet.
Wow what is the price per pound?
Darren G Last time I took some in it was $3/lb. I just looked and it's above $6/lb! 😵
And this stuff is dense.
Hi Darren,
The current rates are:
Europe - € 16/kg (€ 7.2/ lbs)
Americas and Asia - $ 18.8/kg ($ 8.4/lbs)

مرحبا اخي
Excellent video- recycling is vital BUT make sure you get more uses out of your solid carbide tools through Remanufacture. At Quickgirnd in the UK we get tools sent to us from all over the World and in some cases can remanufacture (much more than just regrind) them up to 9 times depending on tool type and required parameters. Including re-coating. This works for our own tools and tools from other manufacturers. After that you can send them for recycling - the cost & energy saved is immense. Mike'Quickgrind.com
So we waited over a year. But you didn’t really show us how you recycle these.
May be proprietary processes.
Hmmm... somehow I thought recycling tungsten carbide would be much... harder.
and yet, you don't show it
Man that chick must have done a line before the video shoot. she is blinking 30 times a second.
Wait what? Wolfram(german word for tungsten) is the biggest producer of tungsten worldwide.... does that make sense🤨🤔
Whats so toxic about carbide though?
It's not so much the carbide, but the cobalt, it's nasty stuff. If you sharpen/hone inserts, wear a mask, & clean up the dust into a zip lock, so you don't have cobalt dust in your shop.
Something I learned recently is vapor or smoke coming off machining should not be breathed, it carries nasty stuff from the tooling AND the material.
I'm ancient & have cancer, already, started w/ throat, now in liver; been working in mechanics, fab, etc since I was 12. Started building/painting models years before.
Never smoked tobacco or chewed.
Any young guys/gals, you don't want this, trust me. It's not the cancer, it's the treatment & its effects; I have a 5mm silicon tube thru my abdomenal wall I eat thru. Going on 4 yrs. No saliva due to radiation damage.
Wear the damn PPE.
@@georgedennison3338 so sorry that it has effected you in this way and your life. Over the last 3 years I've been in quite a few shops that look past the dangers of cobalt. They don't seem to care about the employees health as much as they should. Always cutting corners. Not many good quality shops around. I live in Ontario Canada and the only shop I know of that lives true to their employees health is Armo Tool. They have an incredible team management and provide the healthiest atmosphere and that's not just the air quality.
FOR a couple of years....NOT since
Maybe it would be a good idea to reach out to youtubers who make machining videos. Channels like Abom79 and AvE and Stefan Gotteswinter. Maybe even clickspring. These channels are not first and foremost interested in shilling for freebies, but I bet they would at least be interested in addressing the benefits of recycling valuable materials.
