If you’re in the business of geological exploration, mining, or oil and gas drilling in Iran, you know how critical it is to have reliable rock drilling tools. And when it comes to core drilling—especially in tough formations like hard rock or complex geological layers—TSP core bits are often the go-to choice. TSP, or Thermally Stable Polycrystalline diamond, bits are designed to withstand high temperatures and maintain their cutting efficiency, making them perfect for deep drilling projects. But with so many options out there, finding the right supplier can feel overwhelming. That’s why we’ve put together this guide to the top 10 TSP core bit suppliers, manufacturers, wholesalers, and traders in Iran. Whether you’re a small-scale explorer or a large mining company, this list will help you connect with the best in the business. Let’s start by breaking down what makes a great TSP core bit supplier, and then dive into the top players in the Iranian market.
First off, what should you look for in a TSP core bit supplier? Quality is non-negotiable—subpar bits can slow down projects, increase costs, and even compromise safety. You’ll want suppliers who use high-grade materials, have strict quality control processes, and offer bits tailored to different rock types (think soft sedimentary rocks vs. hard granite). Reliability is another key factor: can they deliver on time, even during peak demand? And let’s not forget expertise—suppliers who understand the ins and outs of core drilling, from bit design to application tips, can be invaluable partners. Now, let’s meet the companies that check all these boxes.

1. Tehran Geological Tools Manufacturing Co.
Let’s kick things off with Tehran Geological Tools Manufacturing Co., a household name in Iran’s
rock drilling tool scene. With over two decades of experience, they’re not just manufacturers—they’re innovators. What sets them apart? Their focus on custom TSP core bits for geological drilling. Whether you’re drilling in the Zagros Mountains or the Khuzestan oil fields, they’ll work with you to design bits that match the specific rock formations you’re up against. We talked to a project manager at a major copper mine in Kerman, and they raved about how Tehran Geological’s bits reduced their drilling time by 20% compared to generic options.
But it’s not just about customization. They also run a tight wholesale operation, making them a favorite for large-scale projects. Their factory outside Tehran uses state-of-the-art machinery to produce bits ranging from 36mm to 150mm in diameter, all tested under simulated downhole conditions to ensure they can handle high heat and pressure. Plus, they’re committed to sustainability—their production process recycles excess diamond grit, which is a nice bonus for eco-conscious buyers. If you’re looking for a one-stop shop for quality and flexibility, these guys should be at the top of your list.
2. Isfahan Core Bit Traders
Next up is Isfahan
Core Bit Traders, a family-owned business that’s been connecting Iranian buyers with top-tier international TSP core bits for over 15 years. They specialize in importing bits from Europe and East Asia, focusing on brands known for their durability in extreme conditions. One of their bestsellers? A German-made TSP bit designed for hard, abrasive rock—perfect for the Alborz mountain range’s granite formations.
What makes Isfahan
Core Bit Traders stand out is their attention to customer service. They don’t just sell you a bit and send you on your way; their team of geologists and drilling experts will help you choose the right product for your project. We spoke to a small exploration company in Yazd that mentioned, “They walked us through three different bit options, explaining why each would work (or not) for our sandstone layers. We ended up saving money by not overbuying a heavy-duty bit when a mid-range one was all we needed.”
They also excel in fast delivery, with a warehouse in Isfahan that stocks over 500 different core bits at any time. So if you’re in a pinch and need bits ASAP for a time-sensitive project, they’re a solid bet.
3. Mashhad Diamond Tools Industries
If you’re after cutting-edge TSP technology, Mashhad Diamond Tools Industries is where it’s at. These folks are all about innovation—their R&D team is constantly tweaking their diamond matrix formulas to improve thermal stability. For those who don’t know, thermal stability is what keeps TSP bits from breaking down when drilling deep, hot holes (we’re talking temperatures over 600°C!). Their latest breakthrough? A new bonding agent that extends bit life by 30% in high-heat environments, which is a game-changer for oil well drilling in southern Iran.
As a manufacturer, they have full control over the production process, from sourcing raw diamonds to final testing. This means they can keep costs competitive while maintaining strict quality standards. A drilling contractor in Ahvaz told us, “Mashhad’s bits cost about 15% less than imported ones, but they last just as long. We’ve switched all our deep-well projects to their TSP bits, and our maintenance costs have dropped significantly.”
They also offer training sessions for drilling crews, teaching them how to properly use and maintain TSP bits to maximize efficiency. It’s this extra level of support that makes them a top choice for both seasoned companies and new players in the industry.
4. Shiraz Drilling Supplies Wholesale
For bulk buyers, Shiraz Drilling Supplies Wholesale is the way to go. They focus on large-volume orders, making them ideal for government projects, mining co-ops, or construction companies with multiple sites. Their claim to fame? Offering wholesale prices that beat most competitors by 10-15%, especially when you order 100+ bits at a time.
But don’t think bulk means sacrificing quality. Shiraz Drilling Sources their TSP bits from a network of trusted manufacturers across Iran, including some of the names on this list. They vet each supplier rigorously, testing samples for hardness, heat resistance, and cutting performance before adding them to their catalog. A procurement officer at a state-owned mining company in Zanjan shared, “We order 500 bits a year from Shiraz, and we’ve never had a batch fail. Their quality control is spot-on, and their prices let us stay under budget.”
They also offer flexible payment plans, which is a big plus for smaller businesses working with tight cash flow. And if you need a mix of TSP bits and other core drilling tools—like reaming shells or core barrels—they can bundle those too, saving you time and shipping costs.
5. Karaj Eco-Drill Technologies
Karaj Eco-Drill Technologies is for the forward-thinking buyer. As both a manufacturer and trader, they’re leading the charge in sustainable rock drilling tools in Iran. Their TSP core bits are made using recycled diamond particles and eco-friendly binders, reducing their carbon footprint without compromising performance. They even offset 10% of their energy use with solar panels at their factory—something that’s becoming increasingly important for international clients with strict ESG (Environmental, Social, Governance) requirements.
But their green focus doesn’t mean they skimp on quality. Their flagship TSP bit, the “EcoCore 3000,” is a hit with geothermal exploration companies in Ardabil, where drilling for renewable energy sources is on the rise. One engineer there told us, “We needed bits that could handle the high temperatures of geothermal wells, and EcoCore 3000 delivered. Plus, knowing we’re supporting sustainable manufacturing makes our stakeholders happy.”
Karaj Eco-Drill also trades in imported sustainable bits from Scandinavia, giving buyers even more eco-friendly options. If you’re looking to align your drilling projects with green initiatives, this is the supplier for you.
6. Bandar Abbas Oilfield Tools Supplier
When it comes to complex geological formations—think fractured limestone or interbedded sandstone and shale—Bandar Abbas Oilfield Tools Supplier is the expert. Based in the heart of Iran’s oil country, they specialize in TSP core bits designed for the unique challenges of the Persian Gulf coastal regions. Their “Strata-Master” series, for example, features a variable diamond concentration pattern that adjusts cutting intensity based on the rock type, reducing vibration and improving core recovery rates.
They work closely with oilfield service companies, providing bits for both onshore and offshore drilling. A senior geologist at a major oil company in Bushehr explained, “Bandar Abbas’s bits are like having a custom suit—they fit the formation perfectly. We used to lose 15-20% of core samples due to bit chatter; with their Strata-Master, that number’s down to 5%.”
They also offer on-site technical support, sending engineers to drilling locations to troubleshoot if issues arise. This hands-on approach has made them a trusted partner for urgent, high-stakes projects where downtime is costly.
7. Qom Core Drilling Accessories Hub
Qom Core Drilling Accessories Hub isn’t just about TSP bits—they’re a one-stop shop for all things core drilling. Need a TSP bit? They’ve got that. Need the core barrel to go with it? Check. How about reaming shells, core catchers, or
drill rods? They’ve got those too. This wholesaler and trader prides itself on making life easier for drillers by offering complete kits, so you don’t have to coordinate with multiple suppliers.
Their TSP bit selection is solid, with options from both Iranian manufacturers and international brands. What really shines, though, is their inventory management. They keep track of common sizes and replacement parts, so you can grab a new bit or a spare core catcher while you’re picking up your regular order. A small drilling crew in Markazi Province told us, “We used to spend half a day driving to different suppliers for bits and accessories. Now we go to Qom Hub and get everything in one trip—it’s saved us so much time.”
They also offer bulk discounts on accessory bundles, which is great for startups or independent drillers looking to stock up without breaking the bank.
8. Tabriz Precision Bits Manufacturing
While many suppliers focus on large-diameter bits for mining or oil drilling, Tabriz Precision Bits Manufacturing caters to the niche of small-diameter TSP core bits. These are essential for projects like environmental soil sampling, archaeological exploration, or small-scale mineral prospecting, where you need precise, narrow cores (think 36mm to 76mm in diameter).
Their bits are known for their accuracy—they use computer-aided design to ensure the diamond cutting surface is perfectly aligned, resulting in clean, intact core samples. A university researcher in Tabriz who studies groundwater contamination shared, “We need tiny, undamaged cores to analyze soil chemistry, and Tabriz Precision’s bits deliver every time. The samples are so clean, our lab results are more reliable.”
They also offer custom diameters for specialized projects, though lead times are a bit longer for those. If you’re working on a small-scale or precision-focused job, Tabriz Precision is worth checking out.
9. Kerman Emergency Drilling Solutions
Sometimes, drilling projects hit a snag—maybe a bit breaks unexpectedly, or a last-minute site change requires a different size. That’s where Kerman Emergency Drilling Solutions comes in. As a supplier, they specialize in fast turnaround for urgent orders. With warehouses in Kerman, Shiraz, and Mashhad, they can get TSP core bits to most parts of Iran within 24-48 hours.
They keep a rotating stock of the most commonly used TSP bit sizes and types, from standard geological bits to heavy-duty mining models. Their team is on call 24/7, so even if you need a bit at 2 a.m. for a critical project, they’ll make it happen. A drilling foreman in Sistan and Baluchestan recalled, “We were drilling a water well for a remote village when our bit failed. Kerman Emergency had a replacement to us within 30 hours—without them, the village would have been without water for another week.”
Of course, this speed comes with a slight premium, but when time is money (or in some cases, critical infrastructure), it’s worth every rial.
10. Rasht International Bit Traders
Rounding out our list is Rasht International Bit Traders, a company that prides itself on its global partnerships. They work with top TSP bit manufacturers from the U.S., Canada, and Australia, bringing premium, high-performance bits to the Iranian market. These bits are often used in specialized projects, like deep gold exploration in the Sar Cheshmeh mine or high-pressure oil well drilling in the Persian Gulf.
What makes Rasht International stand out is their ability to source hard-to-find bits. Need a specific TSP grade for ultra-high-temperature drilling? They can track it down. Looking for a bit with a unique shank design to fit your vintage
drill rig? They’ll find it. A mining consultant in Tehran told us, “When we took on a project in the Alborz Mountains with unusual rock hardness, no local supplier had the right bit. Rasht International tracked down a Canadian brand that specialized in that exact formation—saved our project.”
They do charge more for these specialty bits, but for projects where performance is non-negotiable, the investment pays off. Plus, their team stays up-to-date on international drilling trends, so they can recommend new technologies that might give you an edge.
