What kind of value could you be missing out on in your worn-out tungsten carbide tools? Many machinists and contractors toss aside used drill bits, cutting inserts, or saw blades, thinking they’re just scrap metal. In reality, those beat-up tools contain a hidden treasure: tungsten carbide, a super-hard compound that’s valuable even once the tool itself wears out.
Today, we’ll show you how to reclaim that value from old tungsten carbide tools and turn yesterday’s scraps into a profitable and sustainable resource.
What Makes Tungsten Carbide Tools So Valuable?
We should start by saying that tungsten carbide isn’t your average metal. It’s an alloy of tungsten and carbon famous for its extreme hardness and durability, ranking just below diamond on the hardness scale.
This toughness is why it’s used in cutting and drilling tools (from industrial drill bits to machining inserts) that can grind through steel or rock without dulling quickly.
But beyond its strength, tungsten carbide carries serious material value. Tungsten itself is a scarce element, and demand for it in manufacturing, mining, construction, and defense industries stays high.
Even as scrap, tungsten carbide commands a high price. In fact, it’s one of the most valuable metal scraps on the market.
As of mid-2025, reclaimed tungsten carbide typically sells for between $6 and $12 per pound, depending on its purity and form. That price is dozens of times higher than what common steel scrap fetches for the same weight.
In other words, a bucket of old carbide tool bits could be worth hundreds of dollars in recyclers’ hands, whereas the same weight of regular steel might only bring a few dollars.
Common Objects and Parts Containing Tungsten Carbide Tools
One of the first steps in reclaiming value from tungsten carbide is knowing where to find it. You may be surprised to learn that many everyday industrial tools contain this material.
Here are some common tools and parts that often use tungsten carbide components:
- Machine Tool Inserts and Cutters: Those small replaceable inserts for lathes or milling machines are usually tungsten carbide. End mills, reamers, and drill bits used in CNC machining often have carbide tips or are made entirely of tungsten carbide.
- Masonry and Mining Drill Bits: Heavy-duty drill bits for mining, oil and gas drilling (such as Tri-Cone or PDC bits), and even concrete drilling feature tungsten carbide “teeth” or buttons. These bits embed carbide for toughness. Once worn down, the steel portion may be worthless, but the carbide inside remains quite valuable.
- Saw Blades and Cutting Blades: Many circular saw blades, concrete saws, and even chainsaw blades have tungsten carbide tips on their teeth for extended durability. Over time, the teeth wear out, but the carbide remnants can be collected and recycled.
- Wear Parts and Dies: Industrial equipment often utilizes tungsten carbide in high-wear parts, such as crushing and cutting edges, punches, dies, and anvils.
- Other Items: Tungsten carbide shows up in surprising places: the ball in some ballpoint pens is tungsten carbide, and it’s even used in jewelry like rings.
How can you tell if something is tungsten carbide?
There are a few telltale signs to identify carbide parts among steel scrap:
- Weight and Density: Tungsten carbide is nearly twice as heavy as steel. Pick up a similar-sized piece of suspected carbide and steel; the carbide piece will feel substantially heavier.
- Hardness Test: Carbide is extremely hard and scratch-resistant. It can often scratch ordinary steel, while hardly getting a mark itself. It also doesn’t rust, so a metal tool that hasn’t rusted over time might contain tungsten carbide.
- Magnet Test: Pure tungsten carbide isn’t magnetic; however, many carbide tools utilize a cobalt binder, which makes them slightly magnetic. If a piece is very weakly magnetic or non-magnetic but still metal, that’s another clue it could be carbide.
- Appearance: Carbide inserts or parts often have a dull gray color and a smoother finish compared to rusty iron scrap. Some inserts have code numbers or a “C” stamp indicating carbide. Over time, you’ll learn to spot the look of carbide tooling.
By identifying and sorting out tungsten carbide tools using the tips above, you set the stage to reclaim their value.
5 Reasons to Recycle Tungsten Carbide Tools
Sorting out carbide tools is the first step, but what do you gain by recycling them? It turns out that recycling tungsten carbide offers big benefits on multiple fronts: financially for you, and environmentally for everyone.
Here’s why you should make sure your tungsten carbide scrap gets recycled:
- Cash Back in Your Pocket:
The most immediate benefit is financial. Selling your tungsten carbide scrap can provide a lucrative return. Whether you’re a machine shop owner with a bucket of used inserts or a drilling contractor with piles of worn bits, recycling these can generate a welcome revenue stream.
At $6-$12 a pound in scrap value, even a small collection of carbide adds up to real money. It’s a classic win-win: you declutter your workshop and get paid in the process.
- Conserve a Scarce Resource:
Tungsten isn’t only valuable but also limited. By recycling the tungsten in your old tools, you help conserve a critical resource we could run out of in a few decades.
Every pound of carbide you recycle is a pound of tungsten that doesn’t have to be mined from the earth. This eases the pressure on limited tungsten mines (many of which are in regions where supply can be uncertain) and makes the supply of this metal more sustainable in the long run.
- Save Energy and Reduce Emissions:
Creating tungsten carbide from virgin ore requires intense energy and high-temperature processes. Recycling, on the other hand, uses a fraction of the energy.
In fact, producing new tools from reclaimed carbide uses roughly 70% less energy and produces 40% less CO₂ emissions than starting from scratch. By choosing to recycle, you’re indirectly reducing industrial energy use and contributing to lower greenhouse gas emissions.
- Reduce Waste and Pollution:
Every tungsten carbide tool recycled is one less item sent to a landfill or left to rust in a yard. Tungsten carbide is a very stable material; it won’t decompose or rust away. If dumped as waste, it just sits there indefinitely.
Recycling these tools means less heavy-metal junk in landfills and less environmental risk. It also reduces the need for destructive mining operations to obtain new tungsten.
- Support a Circular Economy:
When you recycle carbide, you’re contributing to a supply chain that keeps valuable materials in circulation rather than discarding them. Approximately 30% of the global tungsten supply now comes from recycled sources, a figure that underscores the importance of recycling in meeting demand.
Your scrap today could become part of a new drill bit, cutting tool, or wear part tomorrow. Major tool manufacturers often rely on reclaimed tungsten in their production. Feed your scrap back into the system, and you help make industry more resilient and sustainable.
How to Reclaim Value from Your Tungsten Carbide Tools
Now that we’ve covered the “why,” let’s get into the “how.” Reclaiming value from tungsten carbide tools is easier than you might think.
You don’t need to extract the carbide yourself; specialized recyclers will handle the heavy lifting (and crushing and smelting). Your job is mainly to identify, sort, and connect with the right buyer.
Here’s a step-by-step guide:
- Collect and Separate Carbide Scrap:
Start by gathering all your worn or broken tungsten carbide tools. Inspect old drill bits, end mills, inserts, and any other tooling that contains carbide components. Keep them separate from regular scrap steel.
This is important: if you throw carbide bits into the general scrap bin, a scrapyard might just pay you steel price for the whole lot. Because carbide is much denser than steel and usually non-magnetic, you can often pick it out easily.
Use the identification tips (weight, hardness, etc.) to avoid missing any pieces. Even small carbide inserts and chips are worth collecting in a dedicated container.
- Clean or Remove Excess Steel (If Feasible):
You’ll get the best price for “clean” carbide scrap (meaning pieces that are purely carbide). Many tools, like drill bits or hole saws, have carbide tips brazed onto steel shanks.
If it’s easy to knock off the carbide piece from a larger steel tool, do so. Don’t risk harm or spend hours; separating clean carbide bits from steel attachments can increase their value.
Some recyclers take whole tools and will do the separation themselves, but they may pay a bit less if they have to process a lot of extra steel.
- Find a Reputable Carbide Recycler:
Not all metal scrapyards handle tungsten carbide due to its specialized nature. Look for a recycler or scrap buyer that specifically advertises the purchase of carbide or high-value alloys. This is where we come in.
For example, we specialize in purchasing tungsten carbide scrap from machine shops, drillers, and manufacturers. A quick online search can help you find buyers; many operate nationwide and will arrange shipping for larger quantities.
Make sure you choose a buyer who recognizes the true value of carbide.
- Get a Quote and Arrange Shipment:
Once you’ve identified a recycler, reach out and get a quote. Provide information on what types of carbide scrap you have (e.g., “50 lbs of used carbide inserts and end mills” or “a bucket of drill bits with carbide tips”). The buyer might ask about the condition or ask for a photo.
They’ll typically offer a price per pound that they base on current tungsten market rates, as well as the purity of your scrap. If you agree, coordinate how to get the scrap to them. Many recyclers will email you a shipping label or even send a collection container for large amounts.
Some local buyers might arrange to pick it up if you have a substantial quantity.
- Reap the Rewards:
After you send off your scrap, the recycler will handle the processing: extracting the tungsten carbide from any surrounding material, cleaning it, and preparing it for recycling into new products.
Once they’ve weighed and assessed the material, you’ll get paid.
