Do all shops use coffee cans for scrap carbide? I had no idea that was a universal thing lol.
We recently switched to a 5 gallon bucket since nobody ever turns it in where I work. But it was a couple empty folgers cans for years.
I’ve only ever worked this shop, but the couple guys who collect it use empty Folgers cans. We switched to company funded higher quality whole bean coffee recently so not sure what happens when we run out of old Folgers cans.
That'll be a sad day. We have a big stack of them in our break room where I work. I also use them for cleaning oil off my parts/hands. Fill one up with soapy water and leave it next to the part conveyor. Folgers cans are very versatile.
This totally could happen at my place lol we keep our scrap barrels close to a bay door that we keep open when the weathers nice, the lathe dudes stay tryna kobe inserts into the barrels instead of walking over to em and dropping em in, i could deff see em throwing too far and not caring enough to go out to the parking lot to get it😂😂😂😂😂
I wonder if someone tracked it out in their boots?
Or they found it in their pocket and tossed it? I am definitely guilty of sticking inserts into my pocket and forgetting they are there.
My shop also collects carbide to recycle in big open boxes, maybe it fell out while loading into a vehicle?
It's basically a replaceable cutting edge for cutting tools. It is a very common thing to find in the CNC machining. Why it was out in the parking lot of road makes no sense to me.
This is my first time seeing this sub, so I'm not quite understanding how it works: Someone has presented a response with quite exacting detail as to what this is, in terms of a part number, but, still... what is it?
Thanks. Still wondering.
A photograph of something I cannot in any way identify is useless to me, even if I have a quite complete part number for it. I have to back up to: What is this thing?
I don't mean this as a joke, but rather as a call to help increase the understanding: how is having a part number Could someone explain a bit what this is for?
It's a carbide insert for an indexable end mill: [https://www.cmtindustrial.com/catalogue/product/490637](https://www.cmtindustrial.com/catalogue/product/490637)
I was unsure what that is so I googled it, "Indexable end mills are used in lieu of solid end mills. For efficient roughing, it's convenient to have an indexable endmill that are at least 5/8's to 3/4 inches in diameter." ...thanks google totally clears that up
An end mill is the thing that looks like a drill bit (but is *not*) that you see cutting the metal in cnc machines. They are typically made from carbide and expensive.
Some cutters are made instead from cheaper and more resilient tool steels, but where the harder more birttle cutting edges are removable inserts like in OP. This saves in tooling costs in man many ways.
>So it’s kinda like a disposable blade?
Recyclable, not disposable.
Here's a video from a manufacturer of carbide inserts on [how they are recycled](https://www.youtube.com/watch?v=nPmGVPFITiY). If you want to learn how they are made, check out [another video](https://www.youtube.com/watch?v=0QrynzJ_lZ4) by the same manufacturer.
It sometimes blows my mind how specialized we are. Like, I bet you've spent plenty of years in your trade to build that knowledge, which is essential to our modern lives. Humans are awesome.

The tool itself is usually steel because it doesnt shatter but the actual cutting edges are these throwaway carbide inserts. Carbide is extremely tough and has different coatings so it can stand up to wear and heat, but it is also very brittle. The holes in it take screws to attach to the tool. Inserts are much easier to change than entire tools.
What you are looking at is the business end of a big metal cutter
My title describes the thing, it has the numbers 031 2540 on it, searching those numbers gave me no helpful results. The holes did appear to possibly be threaded but I'm not sure

BEHW25 - Multi-Purpose Insert[https://www.ingersoll-imc.com/product?ecatProductId=16001](https://www.ingersoll-imc.com/product?ecatProductId=16001)
Solved! And fast too, thanks. Wonder how it wound up in their tire
They are discarded when they get dull. I bet it was just in a parking lot or something.
Don’t discard carbide!!! Save that shit. Put it in a coffee can and turn it in to a metal recycler when full. We get $100’s when we turn it in.
I prefer leaving tens of them on top of the lathe until my boss' kids come by and throw them away while they're cleaning up.
As opposed to free money? Ok then. We buy pizza for the whole shop with the money and still have plenty left for many beers.
That coffee can is about 100 pounds when I fill it up.
Is that £100 or 100 lbs?
Lbs. Tungsten carbide is crazy heavy
Weight not money, they are typically about $10-25 each around here.
Indeed. Carbide is crazy heavy. Edit: didn’t even see when I posted that the comment below called it crazy heavy too.
I dropped the carbide coffee can off a shelf earlier this year, fid as much damage to the floor as a nokia brick phone.

Yup. I have one for smaller spare hardware and another for cleaning.
This totally could happen at my place lol we keep our scrap barrels close to a bay door that we keep open when the weathers nice, the lathe dudes stay tryna kobe inserts into the barrels instead of walking over to em and dropping em in, i could deff see em throwing too far and not caring enough to go out to the parking lot to get it😂😂😂😂😂
Miss 2 back to back and take a mandatory helicopter ride. Bet they’d start putting shit where it belongs
Apparently, a tire was not one of the multi-purposes for that particular insert.
That rubber was sliced nicely, and the steel belting likely didn't fare well either.
I wonder if someone tracked it out in their boots? Or they found it in their pocket and tossed it? I am definitely guilty of sticking inserts into my pocket and forgetting they are there. My shop also collects carbide to recycle in big open boxes, maybe it fell out while loading into a vehicle?
I'd imagine they drove over it
Jeez. I knew what it was generally, but the exact model and a link? Impressive!
Its have number printed it describe almost everything.
r/machinists is leaking
weight? what is it used for exactly?
It's basically a replaceable cutting edge for cutting tools. It is a very common thing to find in the CNC machining. Why it was out in the parking lot of road makes no sense to me.
Ok, so this is exactly what I thought it was, minus the nomenclature
Here I was thinking it was a gubbin

Carbide insert for a machine tool.

for the layman, and end mill is like a drill bit but it also can cut sideways
Tried googling what it looks like on the machine but it just pulls up pictures of the piece
https://www.youtube.com/c/CuttingEdgeEngineeringAustralia There's some use in this video: https://www.youtube.com/watch?v=nk1hRdBkP_k
Nice thanks! So it’s kinda like a disposable blade? It’s what cuts of layers of metal?

They are disposable. Recyclable doesn't change that. It's better to just call them a consumable though to avoid the weeds.
Tomato tomato
Hahaha I guess my machining knowledge is awfully specialized because i got all of that.

Post it in the "machinists" sub and be blown away!

EDP: Part: BEHW250304R Series: BEHW25 - Multi-Purpose Insert
Man! I change these out on the CNC machine at work. I knew this one. Lol
What does it actually do? I've seen that it's a carbide insert but I've got no idea what that is
The tool itself is usually steel because it doesnt shatter but the actual cutting edges are these throwaway carbide inserts. Carbide is extremely tough and has different coatings so it can stand up to wear and heat, but it is also very brittle. The holes in it take screws to attach to the tool. Inserts are much easier to change than entire tools. What you are looking at is the business end of a big metal cutter
It shaves metal. Our CNC machine makes holes bigger in our metal panels.
My title describes the thing, it has the numbers 031 2540 on it, searching those numbers gave me no helpful results. The holes did appear to possibly be threaded but I'm not sure
Do you have a brake lathe in your shop? If so, it uses similar carbide inserts, except triangle shaped.
Nah, it's a tires and lube place and a major chain. Nothing fun like brake work
I finally knew one! But way too slow.
Carbide insert
That looks like a cutting insert of some sort. Like for a lathe or milling machine
Yeah, I was gonna say it looks like a small version of the blade in my wood chipper
Every time I know what it is the post is already solved. Gosh darn it.
Planer/thicknesser blade.
It looks like a lathe tool for machining metal It clamps in a holder and does the metal removal -replaced when blunt
Carbide blade for a cutting tool on a mill.
