Top 10 Surface Set Core Bit Suppliers, Manufacturers, Wholesalers and Traders in Yemen

When it comes to rock drilling tools in Yemen, Yemen RockDrill Solutions (YRS) is a name that's been trusted for over a decade. Based in Sana'a, this family-owned business started as a small trading outfit but has grown into one of the country's leading wholesalers of surface set core bits and rock drilling tool wholesale solutions. What sets YRS apart? Their laser focus on understanding local geology.

"Yemen's rocks aren't like anywhere else—some regions have soft sedimentary layers, others are hard granite or limestone," explains Muhammad Al-Mansoori, YRS's operations manager. "We don't just sell tools; we help clients pick the right surface set core bit for their specific project." YRS's product line includes a range of surface set core bits (from 38mm to 152mm diameters), as well as complementary tools like drill rods, reaming shells, and impregnated core bits for harder formations. Their surface set bits are particularly popular among geological survey teams, thanks to their durable diamond segments that maintain sharpness even in abrasive rock.

For wholesalers and large contractors, YRS offers flexible bulk pricing—orders over 50 units qualify for up to 15% discounts—and same-day delivery within Sana'a. They also partner with international manufacturers to stock hard-to-find sizes, like the 76mm surface set core bit often used in water well exploration. "Our goal is to be a one-stop shop," Al-Mansoori adds. "If you need 100 surface set bits for a mining project in Marib, we'll have them delivered to your site, no hassle."

Nestled in Aden's industrial district, Aden Diamond Tools & Hardware (ADTH) has built its reputation on precision. While they stock a full range of rock drilling tools, their claim to fame is their premium diamond core bit collection—including surface set and impregnated varieties. Founded in 2012 by engineer Fatima Al-Zubair, ADTH prides itself on importing only ISO-certified products, ensuring consistency for clients in the oil and gas sector.

"In oil exploration, a core bit failure can cost thousands of dollars in downtime," says Al-Zubair. "That's why we source our surface set core bits from Germany and South Africa—these bits have a matrix body that resists wear, even when drilling for hours on end." ADTH's surface set lineup includes 3-blade and 4-blade designs, with options for both surface set (exposed diamonds) and hybrid models that combine surface set and impregnated segments for versatility. They also offer custom engraving for bulk orders, making it easy for contractors to track tools across multiple job sites.

Wholesale clients appreciate ADTH's transparent pricing and technical support. Their sales team includes a geologist who can advise on bit selection, and they offer free sample testing—send in a rock sample, and they'll recommend the best surface set core bit for the job. For international clients importing to Yemen, ADTH handles customs clearance, a huge relief given the country's complex logistics. "We've had clients from Oman and Saudi Arabia order through us because we know how to navigate Yemen's ports," Al-Zubair notes. "It's not just about selling bits; it's about solving problems."

On Yemen's western coast, Hodeidah Mining & Construction Supplies (HMCS) has carved out a niche as the go-to supplier for coastal and agricultural projects. While they stock all types of rock drilling tools, their surface set core bits are a favorite among contractors building irrigation wells and coastal roadways. "Coastal areas have unique challenges—saltwater corrosion, soft sandstone, and clay," says Laila Al-Hakimi, HMCS's product development lead. "Our surface set bits are treated with anti-corrosion coatings, which their lifespan in these harsh conditions."

HMCS's surface set core bit range includes specialized models for wet drilling (common in irrigation projects) and dry drilling (used in quarrying). Their 51mm surface set bit, for example, is designed with wider water channels to prevent clogging in clayey soil, a common issue in Tihama's farmlands. They also carry impregnated core bits for clients working in the nearby mountains, where rock is harder and more abrasive. What makes HMCS stand out, though, is their commitment to affordability. "Many small-scale farmers can't afford premium imported bits," Al-Hakimi explains. "We work with local manufacturers to produce budget-friendly surface set core bits that still meet quality standards—perfect for a farmer drilling a 50-meter well for his crops."

For wholesalers, HMCS offers a "mix and match" bulk program: order 20 surface set bits, 10 impregnated bits, and 5 drill rods, and get a combined discount. They also provide training workshops for new clients, teaching teams how to properly maintain surface set bits to extend their life. "A well-maintained bit can last twice as long," Al-Hakimi adds. "We don't just sell tools—we help our clients get the most out of them."

Taiz RockTech Industries is a relative newcomer to the scene—founded in 2018—but they've quickly made a name for themselves with their innovative surface set core bits. Located in Taiz's industrial zone, RockTech focuses on manufacturing, not just trading, producing 60% of their surface set bits in-house using locally sourced steel and imported diamond grit. "We wanted to reduce reliance on imports," says Ahmed Al-Taher, RockTech's founder. "By making our own bits, we can control quality and keep prices stable, even when international shipping gets disrupted."

RockTech's flagship product is their "SuperSet" surface set core bit, which features a matrix body reinforced with tungsten carbide inserts for added strength. "Traditional surface set bits can crack under high pressure in hard rock," Al-Taher explains. "The SuperSet's matrix body flexes slightly, absorbing shock and preventing breakage." These bits are popular with mining companies in Lahj and Abyan, where hard quartzite formations are common. RockTech also offers custom sizing—if a client needs a 113mm surface set bit with a specific thread type, they can produce it in as little as two weeks.

For wholesalers, RockTech's factory-direct model means lower prices—no middleman markup. They also offer private labeling, allowing businesses to brand the surface set bits with their own logo. "We've had clients from Djibouti and Eritrea order our bits under their own brand," Al-Taher notes. "It's a win-win: they get high-quality tools at a good price, and we expand our reach." With a production capacity of 500 bits per month, RockTech can handle large orders, making them a top choice for government infrastructure projects.

Hadhramaut Diamond Tools (HDT) serves the rugged eastern region of Yemen, where mining (gold, copper, and limestone) is a major industry. Based in Mukalla, HDT specializes in high-performance surface set core bits and diamond core bit variants for extreme conditions. "Hadhramaut's mountains are unforgiving—hard rock, high temperatures, and remote locations," says Salim Al-Bahri, HDT's technical director. "Our bits are built to withstand that."

HDT's surface set core bits are known for their precision. Their 94mm "GeoPro" bit, for example, is used by geological survey teams to extract intact core samples for mineral analysis. "In mining exploration, you need a clean sample—no cracks or contamination," Al-Bahri explains. "The GeoPro's diamond segments are arranged in a spiral pattern, ensuring smooth cutting and minimal sample damage." They also stock large-diameter surface set bits (up to 203mm) for quarrying operations, where speed and durability are key. For clients working in remote areas, HDT offers a "field support" service: a technician can visit the site to help troubleshoot bit performance or recommend adjustments.

Wholesalers appreciate HDT's reliability—they maintain a large inventory, so even hard-to-find bits are usually in stock. They also offer long-term contracts for mining companies, locking in pricing for up to a year to protect against market fluctuations. "Mining projects can span years," Al-Bahri says. "Our clients don't want to worry about price hikes mid-project. We give them stability."

A fixture in Sana'a's Old City market since 1995, Sana'a Industrial Hardware & Tools (SIHT) is a supplier with a loyal customer base. While they sell everything from hand tools to heavy machinery, their surface set core bits are a top seller, thanks to their decades of industry knowledge. "We've seen it all," says Nasser Al-Hamdi, SIHT's third-generation owner. "When a client walks in and says, 'I need a bit for drilling in Ibb's red soil,' we know exactly which surface set model to—no guesswork."

SIHT's surface set core bit range is diverse, covering diameters from 32mm (used in gemstone prospecting) to 127mm (for large-scale construction). They're particularly known for their "Heritage" line of surface set bits, which are designed to mimic the durability of vintage tools but with modern diamond technology. "Older drillers often say, 'They don't make bits like they used to,'" Al-Hamdi laughs. "Well, we do. The Heritage bits have thicker steel bodies and higher diamond concentration—they last longer, even in tough rock."

For wholesalers, SIHT offers a loyalty program: accumulate points with each bulk order and redeem them for discounts or free tools. They also have a dedicated wholesale desk in their Sana'a warehouse, staffed by reps who speak English, Arabic, and Somali to assist international clients. "We get a lot of traders from Somalia and Ethiopia buying surface set bits for their own markets," Al-Hamdi notes. "They trust our quality, and we make the process easy—no complicated paperwork, just straightforward pricing."

Nestled in the fertile highlands of Ibb, Ibb RockDrill & Exploration (IRDE) caters to a unique mix of clients: coffee farmers drilling irrigation wells, quarry operators extracting marble, and geological teams exploring for minerals in the nearby mountains. "Ibb's geology is a mix of soft volcanic rock and hard limestone," says Amal Al-Saadi, IRDE's sales manager. "Our surface set core bits are designed to handle both—versatility is key here."

IRDE's star product is their "DualSet" surface set core bit, which combines surface set diamonds for initial cutting and a thin layer of impregnated diamonds for finishing—ideal for mixed rock formations. "Imagine drilling through 10 meters of soft tuff, then hitting a layer of hard dolomite," Al-Saadi explains. "The DualSet transitions smoothly, so you don't have to stop and change bits." They also stock mini surface set bits (as small as 25mm) for coffee farmers drilling shallow wells, priced affordably to fit small budgets. "A farmer might only need one bit for his well," Al-Saadi adds. "We don't force him to buy in bulk—we'll sell him one, with a smile."

For wholesalers, IRDE offers regional delivery hubs in Taiz and Dhamar, reducing shipping times to nearby provinces. They also provide a "test and return" policy for first-time buyers: order a sample batch of surface set bits, test them on your project, and return any unused ones for a full refund if they don't perform. "We stand behind our products," Al-Saadi says. "If a bit fails prematurely, we ｒｅｐｌａｃｅ it—no questions asked."

For businesses that need access to international brands, Aden International Trading (AIT) is the place to go. Located in Aden's Free Zone, AIT imports premium surface set core bits and rock drilling tools from leading global manufacturers, including Boart Longyear, Atlas Copco, and Sandvik. "We focus on clients who demand the best—oil companies, large construction firms, and international NGOs," says Ali Al-Mahdi, AIT's import manager. "When a client is drilling a 2,000-meter oil well in Shabwah, they don't want to take chances with untested bits. They want the same brands used in Texas or the North Sea."

AIT's surface set core bit lineup includes high-end models like the Boart Longyear T38 surface set bit, known for its precision in geological coring, and the Sandvik R32 thread button bit for hard rock mining. They also stock specialized bits, such as the 152mm surface set core bit used in offshore drilling projects. While their prices are higher than local suppliers, AIT justifies the cost with rigorous quality control: every batch of bits is tested in their on-site lab to ensure it meets international standards. "We once rejected a shipment of bits because the diamond concentration was 5% below the manufacturer's specs," Al-Mahdi notes. "Our clients trust us to deliver only the best."

For wholesalers, AIT offers exclusive distribution rights for certain brands in Yemen. "If you want to be the sole wholesaler of Sandvik surface set bits in Hadhramaut, we can make that happen," Al-Mahdi explains. They also provide technical support from international engineers, who visit Yemen quarterly to train clients on new products. "It's not just about selling a bit," he adds. "It's about building long-term partnerships with companies that share our commitment to excellence."

Dhamar, often called Yemen's "agricultural heartland," is home to Dhamar Construction & Mining Supplies (DCMS), a supplier that understands the unique needs of rural projects. While they stock all types of rock drilling tools, their surface set core bits are a hit with local contractors building rural roads, schools, and water wells. "Rural areas have limited access to equipment, so our bits need to be tough and low-maintenance," says Fatima Al-Dhamari, DCMS's founder. "A farmer in Rada'a can't afford to send a bit back for repairs—he needs it to work, right out of the box."

DCMS's surface set core bits are designed with simplicity in mind: they have fewer moving parts, thicker steel bodies, and standard thread sizes that fit most local drill rigs. Their 57mm surface set bit, for example, is a favorite for small-scale water well drilling, thanks to its lightweight design (easy to handle with manual rigs) and self-sharpening diamond segments. They also offer a "Rural Pack"—a bundle of 5 surface set bits, 2 drill rods, and a sharpening tool—priced to fit a village cooperative's budget. "We believe everyone should have access to quality tools, no matter where they live," Al-Dhamari says.

For wholesalers, DCMS offers flexible payment terms—critical for small businesses in cash-strapped rural areas. "We'll accept partial payments or trade credit for regular clients," Al-Dhamari explains. They also run a mobile sales van that visits remote towns like Yarim and Manakhah, bringing surface set bits and advice directly to clients. "A lot of our clients can't travel to Dhamar, so we go to them," she adds. "It's old-fashioned customer service, but it works."

Last but certainly not least, Marib Oilfield Tools (MOT) caters to Yemen's oil and gas sector, which drives much of the country's demand for high-performance rock drilling tools. Based in Marib, Yemen's oil capital, MOT specializes in surface set core bits and related tools for oil well exploration and production. "Oil drilling is a high-stakes business—one failed bit can cost millions in downtime," says Khalid Al-Muradi, MOT's technical sales director. "Our bits are built to withstand the extreme conditions of oil wells: high pressure, high temperature, and abrasive rock."

MOT's product line includes API-certified surface set core bits (required for international oil projects), as well as specialized bits like the 216mm matrix body PDC bit for horizontal drilling. Their surface set bits are designed with extra-thick diamond segments to handle the high torque of oilfield drill rigs, and they undergo rigorous testing in simulated downhole conditions before being sold. "We test each bit at 150°C and 5,000 psi—conditions harsher than most Yemeni oil wells—to ensure they won't fail," Al-Muradi explains. They also stock replacement parts, like PDC cutters and retainers, for quick repairs on-site.

For wholesalers, MOT offers bulk discounts for oilfield contractors—orders over 100 bits qualify for 20% off—and priority delivery to remote oilfields like Block 18. They also provide 24/7 technical support, with a team of engineers on call to troubleshoot bit performance. "If a rig in Shabwah is having issues with a surface set bit at 2 a.m., we'll be on the phone walking them through a fix," Al-Muradi says. "In the oil business, time is money, and we help our clients save both."
