Founded in 2010, Sierra Diamond Drilling Supplies (SDDS) has grown to become a household name among small and medium-scale miners in Sierra Leone. Based in Freetown with satellite offices in Bo and Kenema, SDDS prides itself on understanding the unique challenges faced by local miners—from limited budgets to remote project sites. Their specialization in surface set core bits and diamond core bits has made them a go-to for those needing reliable tools for geological drilling in diamond and gold-rich areas like Kono and Tongo Fields.
SDDS's biggest advantage is its local roots. Unlike international suppliers that may take weeks to deliver, SDDS maintains a large inventory in Freetown, ensuring that orders for standard surface set core bits (such as 4 7/8-inch PQ3 models) can be shipped within 24–48 hours. They also offer customization: if a miner needs a surface set core bit with a specific diamond concentration for harder rock formations, SDDS's in-house technical team can adjust the design and have it ready within a week. This flexibility has earned them a loyal customer base among artisanal miners who often work with unique, small-scale projects.
Many customers praise SDDS for their hands-on approach. "When I started my diamond mining project in Kono, I didn't know much about core bits," says Alusine Kamara, a local miner. "The team at SDDS walked me through the options, recommended a 3-inch surface set core bit for the soil there, and even sent a technician to help set it up. Six months later, that bit is still going strong."
As a subsidiary of a European drilling equipment manufacturer, West African Core Bits Ltd. (WACB) brings international expertise to Sierra Leone's mining sector. Established in 2005, WACB operates a state-of-the-art warehouse in Freetown and partners with global brands to import high-quality surface set core bits and mining cutting tools that meet API and ISO standards. Their client list includes major mining corporations like African Minerals and Octea, making them a trusted name in large-scale operations.
WACB's strength lies in its commitment to quality and technical support. Unlike local suppliers, they invest heavily in training: their team of geological engineers regularly conducts workshops for clients on topics like "Maximizing Surface Set Core Bit Lifespan" and "Choosing the Right Core Bit for Rock Type." They also offer bulk wholesale pricing, which is critical for large mining projects that require hundreds of core bits annually. For example, a recent order for a gold mine in Koinadugu included 500 surface set core bits (6-inch API matrix body models) at a 15% discount, saving the client over $20,000.
WACB's parent company has manufacturing facilities in Germany and China, allowing them to source products at competitive prices. However, they've also invested in local assembly: their Freetown workshop assembles surface set core bits using imported diamond segments and local steel, reducing costs and supporting the local economy. This hybrid model—global quality with local production—has made them a favorite among international mining firms operating in Sierra Leone.
MiningTech Sierra Leone is a wholesaler and distributor that prides itself on affordability without compromising quality. Founded in 2012, they've built a reputation for offering some of the lowest prices on surface set core bits and carbide core bits in the country, making them popular with mid-sized mining companies and construction firms working on infrastructure projects like road building and pipeline laying.
MiningTech's secret to low prices is its direct relationships with manufacturers in China and India. By cutting out middlemen, they can offer a 4-inch surface set core bit for as little as $150, compared to $200–$250 from other suppliers. They also specialize in bulk orders: a construction company working on the Freetown–Bo highway recently ordered 200 3-inch surface set core bits for soil testing, and MiningTech delivered them within 10 days at a 20% bulk discount.
While MiningTech is known for low prices, they don't skimp on service. They offer a 30-day warranty on all surface set core bits, and if a bit fails prematurely due to manufacturing defects, they ｒｅｐｌａｃｅ it free of charge. "We had a batch of carbide core bits that didn't perform well in our pipeline project," recalls Ibrahim Jalloh, a construction manager. "MiningTech sent a technician to inspect the site, realized the rock was harder than we'd anticipated, and replaced them with surface set bits at no extra cost. That's the kind of service you don't get from just any wholesaler."
Based in the coastal city of Bonthe, Coastal Drilling Accessories (CDA) caters to a niche but vital market: marine and coastal geological exploration. Sierra Leone's coastal regions are rich in mineral sands (e.g., rutile, zircon) and offshore diamond deposits, and drilling in these environments requires specialized equipment that can resist corrosion from saltwater. CDA has become the leading supplier of surface set core bits and diamond core bits for coastal and marine projects, serving clients like the Sierra Leone Geological Survey and international mineral exploration firms.
CDA's core innovation is its corrosion-resistant surface set core bits. Traditional core bits can rust quickly in saltwater, reducing their lifespan by up to 50%. CDA treats its bits with a special nickel-plated coating and uses stainless steel bodies, extending their durability in coastal conditions. They also offer waterproof core barrels, ensuring that rock samples collected from offshore drilling remain intact and uncontaminated by seawater.
CDA is also committed to supporting local coastal communities. They run training programs for young people in Bonthe, teaching them how to maintain and repair surface set core bits, creating jobs in a region where employment opportunities are limited. "Many of our technicians started as trainees," says CDA's manager, Mariama Sesay. "We believe that by investing in the community, we're not just selling core bits—we're building a sustainable mining ecosystem on the coast."
African Drill Masters (ADM) is all about innovation. Founded by a team of geological engineers in 2018, ADM set out to solve a common problem in Sierra Leone's mining industry: surface set core bits that underperform in the country's diverse rock formations (from soft alluvial soils in the south to hard gneiss in the east). Through extensive research and development, they've created a line of surface set core bits tailored specifically to Sierra Leone's geology, earning them a reputation as the "problem-solvers" of the core bit market.
ADM's R&D lab in Freetown is equipped with rock testing equipment, allowing them to analyze samples from a client's project site and recommend (or design) the perfect surface set core bit. For example, if a miner in Koinadugu is drilling through iron-rich rock with high silica content—a notoriously tough formation—ADM can adjust the diamond size, concentration, and bonding agent in the surface set segments to ensure optimal cutting efficiency. This level of customization is rare in Sierra Leone and has made ADM a partner of choice for complex geological surveys.
ADM also partners with the University of Sierra Leone's geology department, funding research into local rock formations and how they interact with core bits. This academic-industry collaboration ensures that their products are always at the cutting edge. "We're not just selling tools—we're advancing the science of drilling in Sierra Leone," says Dr. James Kargbo, ADM's lead geologist. "Every surface set core bit we design is backed by data from local rock samples, making them more effective than generic international models."
Sierra Leone Core Bit Wholesalers (SLCBW) is the middleman that keeps Sierra Leone's mining industry supplied. Unlike manufacturers or specialized suppliers, SLCBW doesn't produce core bits itself—instead, it partners with over 20 international manufacturers (from China, India, Turkey, and South Africa) to import bulk quantities of surface set core bits , core bits , and related tools, then distributes them to local retailers, mining companies, and even other suppliers. With warehouses in Freetown, Makeni, and Bo, SLCBW acts as a logistical hub, ensuring that core bits are available across the country, even in remote mining regions.
SLCBW's strength is its global network. By working with multiple manufacturers, they can offer an unparalleled range of surface set core bits—from budget-friendly Chinese models to premium German-engineered bits—all under one roof. This variety is critical for Sierra Leone's diverse mining sector: a small-scale gold miner in Moyamba might need a basic 2-inch surface set core bit for $80, while a large iron ore mine in Port Loko could require a high-end 8-inch API-certified bit for $1,500. SLCBW can supply both, often at lower prices than buying directly from the manufacturer due to their bulk purchasing power.
Importing core bits into Sierra Leone can be challenging, with customs delays and poor road infrastructure in rural areas. SLCBW has mastered this process: they have a dedicated logistics team that handles customs clearance, and they partner with local transporters who specialize in delivering to remote mining sites. "We once had an order for 100 surface set core bits to a mine in Kailahun, which is hours from the main road," says a SLCBW logistics manager. "Our team used motorbikes to carry the bits the last 20 kilometers—whatever it takes to get the tools to the miners who need them."
DiamondTech Exploration Tools is all about precision. While many suppliers focus on durability or cost, DiamondTech specializes in diamond core bits (including surface set models) that deliver extremely accurate geological samples—critical for exploration firms that need to analyze rock composition down to the micron. With clients ranging from junior exploration companies to the United Nations Development Programme (UNDP) geological projects, DiamondTech has built a reputation for producing core bits that minimize sample contamination and maximize data quality.
DiamondTech's surface set core bits are engineered with ultra-fine diamond particles and a proprietary bonding agent that ensures clean, precise cuts. When a geologist extracts a core sample using a DiamondTech bit, the sample is less likely to be fractured or mixed with debris, making it easier to analyze mineral content. This precision is especially valuable for diamond exploration, where even a tiny fragment of kimberlite (the rock that contains diamonds) can indicate a potential deposit.
DiamondTech doesn't just sell bits—they educate their clients. They offer workshops for geologists on "Best Practices for Core Sampling," teaching techniques to maximize the accuracy of samples collected with their surface set core bits. "A high-quality core bit is only as good as the person using it," says DiamondTech's training coordinator. "We want to ensure that our clients get the most out of their investment, so we teach them how to adjust drilling speed, pressure, and coolant use to get perfect samples every time."
As a state-owned enterprise under the Ministry of Mines and Mineral Resources, National Mining Supplies (NMS) plays a critical role in supporting Sierra Leone's mining industry. Established in 1995, NMS was created to ensure a reliable supply of essential mining equipment—including surface set core bits and mining cutting tools —to both government projects and private miners, particularly during times of economic instability or supply chain disruptions.
NMS's biggest advantage is its stability. While private suppliers may face cash flow issues or stock shortages, NMS has government backing, allowing it to maintain large inventories and weather market fluctuations. This makes them a trusted partner for long-term projects, such as the government's ongoing geological mapping initiative, which requires consistent supplies of surface set core bits for surveying across the country. NMS also offers preferential pricing to small-scale and artisanal miners, helping to support local communities and reduce reliance on imported, overpriced equipment.
NMS's mandate goes beyond profit—it's about national development. A portion of their revenue is reinvested into mining education and safety training for artisanal miners. For example, they recently launched a program to distribute free safety gear (gloves, goggles) to miners who purchase surface set core bits, helping to reduce accidents in the industry. "NMS isn't just a supplier—they're a partner in Sierra Leone's mining future," says a Ministry of Mines spokesperson. "By ensuring access to affordable, quality core bits, they're helping to unlock the country's mineral potential for everyone."
Global Drilling Solutions SL (GDS) is the Sierra Leonean branch of a multinational drilling equipment corporation with operations in over 30 countries. Since opening its doors in Freetown in 2018, GDS has focused on bringing cutting-edge international technology to Sierra Leone's mining sector, specializing in surface set core bits , DTH drilling tools , and large-scale drill rigs. Their clients include major international mining companies like Rio Tinto and small to medium firms looking to upgrade their equipment.
GDS's strength is its access to global innovation. Their surface set core bits are designed using computer-aided design (CAD) software and tested in state-of-the-art labs, ensuring they meet the highest international standards. For example, their "UltraCut" surface set core bits feature a patented diamond segment arrangement that reduces drilling time by up to 30% compared to standard bits, a game-changer for large mining projects where time is money. GDS also offers technical training: their Freetown training center hosts courses on drill rig operation and core bit maintenance, taught by international instructors.
International mining companies often cite after-sales support as a key concern when operating in developing countries. GDS addresses this with a team of 10 certified technicians based in Freetown, who can be dispatched to mine sites within 24 hours to repair or maintain equipment. "When you buy a surface set core bit from GDS, you're not just buying a tool—you're buying peace of mind," says a GDS sales manager. "Our technicians have worked on mining sites in Australia, Canada, and South Africa, so they bring global expertise to solve local problems."
Eastern Region Drilling Co. (ERDC) is a community-focused supplier serving the mining-rich eastern provinces of Sierra Leone, including Kono, Kenema, and Kailahun. Founded in 2015 by a group of local miners, ERDC was created to address a gap in the market: remote eastern communities often struggled to access quality surface set core bits and drilling tools, forcing them to rely on overpriced, low-quality imports from neighboring Guinea or Liberia. Today, ERDC has stores in Kenema and Kono, providing affordable, reliable equipment to the region's miners.
ERDC's biggest asset is its deep understanding of eastern Sierra Leone's mining landscape. The company's founders are former miners themselves, so they know the unique challenges of drilling in the region—from the alluvial diamond deposits of Kono to the hard rock gold mines of Kenema. This local knowledge allows them to recommend the right surface set core bit for each project, often at prices 20–30% lower than suppliers in Freetown, thanks to lower overhead costs.
ERDC is more than a business—it's a community pillar. They offer flexible payment plans for miners (e.g., "pay half now, half when you sell your ore"), and a portion of their profits funds local schools and healthcare clinics. "ERDC doesn't just sell us core bits—they invest in our communities," says Mohamed Turay, a gold miner in Kenema. "When my son got sick last year, they helped pay for his hospital bills. That's why we'll always buy from them, even if there's a cheaper option in Freetown."
Sierra Leone's mining industry is a vital driver of economic growth, and reliable access to quality surface set core bits is essential to unlocking its full potential. Whether you're a small-scale miner in Kono, a large international mining corporation, or a geological survey firm, the suppliers on this list offer a range of solutions to meet your needs—from affordable local options to cutting-edge international technology. By considering factors like project size, rock formation, location, and budget, you can choose the supplier that will help you drill deeper, extract better samples, and ultimately, succeed in Sierra Leone's dynamic mining sector.
