Is there hidden treasure in your old drill bits? For many in mining, construction, or oil drilling, worn-out Tri-Cone and PDC bits often pile up as “scrap.” Yet inside these hefty tools lies something far more valuable than ordinary metal. The secret is tungsten carbide recycling – a super-hard material embedded in drill bits that can be reclaimed for surprising value.
Tungsten Carbide Recycling
Instead of treating used bits as junk, learning how to recycle their tungsten carbide content can turn industrial waste into profit and sustainability gains.
What Are Tri-Cone and PDC Drill Bits?
Tri-Cone and Polycrystalline Diamond Compact (PDC) drill bits are go-to tools for tough drilling projects, from mining and oil extraction to geothermal wells. They are engineered to withstand extreme conditions primarily because of their tungsten carbide components.
Tungsten carbide is an alloy renowned for its hardness and durability – it’s an extremely hard metal, second only to diamond in hardness. This toughness is what allows drill bits to grind through rock and earth without wearing down immediately.
Tri-Cone Bits
These bits have three conical rollers (or “cones”) studded with teeth. There are two main types: milled steel teeth for softer formations and Tungsten Carbide Insert (TCI) teeth for harder rock.
In TCI tri-cone bits, the “buttons” on the cones are tungsten carbide inserts, giving the bit superior wear resistance. As the drill rotates, the cones roll and the carbide teeth crush and chip the rock. This design has been a workhorse of drilling since the early 1900s and remains widely used for its reliability.
PDC Bits
PDC bits have a single solid head (no moving cones) with flat faces where PDC cutters are attached. Each cutter is a wafer of synthetic polycrystalline diamond fused to a tungsten carbide base. The diamonds provide cutting power, while the tungsten carbide base supports and absorbs heat.
PDC bits often use a matrix body made of tungsten carbide for improved abrasion resistance in abrasive formations, or a steel body for less abrasive conditions. Either way, tungsten carbide is a significant part of PDC bits’ construction. This allows PDC bits to chew through tough rock with high efficiency, making them popular in modern oil and gas drilling.
Both tri-cone and PDC bits owe much of their performance to tungsten carbide. But what happens when these bits reach the end of their service life? Even the toughest bit wears out eventually.
Drill bits can fail due to worn-down teeth, cracked cones, or simply becoming too dull for further use. At that point, they’re pulled out of service – and this is where recycling opportunities come into play.
Tungsten Carbide Recycling: Hidden Treasure in “Scrap” Drill Bits
A worn drill bit might look like a lump of useless steel, but it hides valuable tungsten carbide within.
In fact, many old tri-cone, hammer, and PDC bits are laden with tungsten carbide inserts and compacts that retain significant value. The problem is that if these bits are tossed in with general scrap metal, their owners might literally be throwing money away.
Too often, retired drill bits end up categorized as common heavy melt steel scrap at junkyards. Heavy melt scrap is bought cheaply, since it’s just generic steel and iron. If scrap dealers looked a little closer at those junk bits, they would see something much more valuable.
The tungsten carbide embedded in drill bits is worth many times more per pound than regular steel.
How valuable are we talking? Tungsten carbide scrap is one of the most valuable scraps on the metal market.
As of mid-2025, reclaimed tungsten carbide generally sells for about $6 to $12 per pound, depending on purity and form. That price is dozens of times higher than what you’d get for the same weight in plain steel.
This hidden treasure aspect is exactly how some companies in the recycling industry got started. In one case, a recycler realized that old mining drill bits contained valuable tungsten carbide and began extracting the carbide to sell it separately from the steel.
The lesson for anyone with used drill bits is clear: don’t just toss them in the scrap bin with iron and steel. By recognizing the tungsten carbide content, you can literally turn trash into cash. It’s not only an economic win for you, but it sets the stage for that material to be repurposed into new tools and products.
Why Start Recycling Tungsten Carbide from Drill Bits
Recycling tungsten carbide isn’t just about the money – it also yields important environmental and strategic benefits. Tungsten itself is a limited resource, and demand for it in industries like manufacturing, construction, mining, and defense remains consistently high.
When you recycle carbide inserts and cutters from drill bits, you’re helping put a finite resource back into use instead of letting it go to waste.
Here are some noteworthy benefits of recycling tungsten carbide:
Conserve Resources
Tungsten is a scarce mineral, with global reserves estimated to last only about 40-100 years at current consumption. Recovering tungsten from used bits reduces the need to mine new ore. It also lessens reliance on a supply chain dominated by a few countries. (Without recycling, much of the world’s tungsten supply depends on exports from places like China.)
Energy and Emissions Savings
Manufacturing new tungsten carbide from raw ore is resource-intensive and energy-hungry. Recycling scrap carbide, on the other hand, uses 70% less energy and emits 40% less carbon dioxide compared to producing the same amount from virgin tungsten.
Mining and refining tungsten puts a heavy burden on the environment, so every pound of carbide recycled means less greenhouse gas emissions and less ecological disturbance.
Waste Reduction
Every recycled drill bit means fewer heavy metal items going to landfills or rusting away in scrap yards. Tungsten carbide, when left as waste, doesn’t decompose – it’s an inert material just sitting there.
Recycling ensures these hard metal pieces are cleaned and reused instead of becoming industrial waste. It also reduces the volume of overall mining waste by decreasing demand for freshly mined tungsten.
Financial Returns
Let’s not forget the direct economic benefit. Recycling tungsten carbide puts money back in your pocket. Whether you’re a drilling contractor, a mining company, or a machine shop, selling your spent carbide bits and inserts provides a welcome revenue stream.
Supporting a Circular Economy
When you recycle tungsten carbide, you are participating in a circular supply chain for critical materials. Approximately 30% of the global tungsten supply now comes from recycled sources, highlighting the importance of recycling in meeting industry demand. By contributing your scrap, you help keep tungsten in circulation.
Manufacturers can turn recycled carbide into brand-new drill bits, cutting tools, or wear parts of the same quality as those made from mined tungsten. This reduces dependence on mining and fosters a more sustainable industrial ecosystem.
t’s no surprise that major tooling companies and savvy drillers alike promote carbide recycling as part of their operations.
How to Recycle Your Drill Bits (and Reclaim the Value)
By now, the advantages of recycling tungsten carbide are clear. So, how can you actually go about doing it?
The good news is that recycling drill bits is easier than you might think, especially if you partner with a recycler that specializes in carbide.
Here are some simple steps to ensure you maximize the value of your used tri-cone and PDC bits:
Set Aside Carbide-Containing Bits
Start by identifying and segregating any drill bits or tooling that contain tungsten carbide. This includes tri-cone bits with tungsten carbide inserts (TCI bits) and any PDC bits. Don’t let these valuable items get mixed in with common scrap steel.
Tungsten carbide is much denser than steel and often non-magnetic – these traits can help spot it. Keeping carbide scrap separate will help you get the best price, since it won’t be lumped into “heavy melt” steel weight by a junkyard.
Find a Reputable Carbide Recycler
Not all scrap yards deal with tungsten carbide, so do a little research and find a buyer or recycling company experienced in high-value alloy scrap.
Specialty metal recyclers (like Scrap Gators in Florida, or others) actively buy tungsten carbide from drill bits, mining equipment, and machine shops.
Remember, as mentioned, carbide scrap can fetch $6-$12 per pound or more, so you want a recycler who recognizes that value. Many such recyclers will work with clients nationwide, arranging shipping or pickup for bulk materials.
Get a Quote and Arrange Pickup/Shipping
Once you’ve identified a trusted recycler, reach out for a price quote. You’ll typically discuss the type of bits you have, approximate quantities, and their condition. The recycler may ask for photos or an estimated weight.
Based on tungsten prices and the form of your scrap, they’ll quote a price per pound. For large quantities, they might send a collection bin or even send someone to pick up the material.
Reap the Rewards (Financial and Environmental)
After you send off the bits, the recycler will handle the dirty work of extracting tungsten carbide from the steel. They’ll separate the carbide “buttons” or PDC cutters, clean them, and prepare them for recycling into new material. You’ll receive payment based on the final weight of recoverable carbide.
Following these steps ensures that you wield the full value from tungsten carbide in your drill bits. It transforms a disposal problem into an opportunity.
