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

Founded in 2005, Kenya Drilling Tools Co., Ltd. (KDT) is a household name in Kenya's drilling industry, with headquarters in Nairobi's Industrial Area and a distribution network spanning Mombasa, Kisumu, and Eldoret. What sets KDT apart is its dual focus on manufacturing and wholesale, making it a one-stop shop for both small businesses and large industrial clients.

Specializing in surface set core bits, KDT offers a wide range of sizes, from small BQ (36.5mm) bits for detailed geological sampling to large PQ (85mm) bits for heavy-duty mining projects. Their bits are known for their high diamond concentration—up to 40 carats per crown—and a matrix blend of tungsten carbide and copper, which balances hardness and toughness for long wear life. "We test every batch of bits in our on-site drilling yard before shipping," says John Mbithi, KDT's production manager. "We want our customers to trust that when they buy from us, they're getting a tool that can handle Kenya's toughest rocks."

KDT's wholesale program is popular among local hardware stores and drilling contractors, with minimum orders starting at 20 units for bulk pricing. They also offer custom bit designs, working with clients to create bits tailored to specific rock types—like the "Rift Valley Special," a surface set core bit optimized for the region's volcanic tuff. Industries served include mining (clients include Base Titanium in Kwale), construction (supplying bits for the Nairobi Expressway project), and agricultural irrigation (partnering with NGOs to drill community water wells).

East African Core Bits Manufacturers (EACM) has been a pioneer in local manufacturing since 2010, with a state-of-the-art factory in Thika that produces over 5,000 surface set core bits annually. Unlike many competitors that import bits from Asia or Europe, EACM manufactures its bits locally, reducing lead times and supporting Kenya's "Buy Kenyan, Build Kenyan" initiative.

EACM's surface set core bits are designed with Kenya's geology in mind. Their bestseller, the "KenyaMax" series, features a unique diamond grading system: "Soft" (for sedimentary rocks like sandstone), "Medium" (for limestone and marble), and "Hard" (for granite and basalt). Each grade uses diamonds sourced from ethical mines in Tanzania and South Africa, ensuring both quality and sustainability. "We know Kenyan drillers face unique challenges," explains Sarah Wanjiru, EACM's sales director. "Our bits are tested in the field with local contractors, so we can tweak the design based on real feedback."

As a wholesaler, EACM caters to businesses of all sizes, with no minimum order for small clients and discounted rates for orders over 100 units. They also stock related drilling accessories, including core barrels, drill rods, and reaming shells, making them a convenient partner for full drilling setups. Clients include the Kenya Geological Survey, which uses EACM's bits for national mapping projects, and small-scale miners in Western Kenya who rely on their affordable "EntryLine" series for artisanal gold exploration.

If you're looking for bulk quantities at competitive prices, Nairobi Wholesale Drilling Supplies (NWDS) is a go-to. Established in 2012, NWDS focuses solely on wholesale, importing high-quality surface set core bits from leading manufacturers in China and India, then distributing them across Kenya at wholesale rates. Their warehouse in Nairobi's Embakasi area stocks over 10,000 bits at any given time, ensuring fast delivery even for large orders.

NWDS prides itself on variety, offering surface set core bits in every standard size (BQ, NQ, HQ, PQ) and for every application. Their "ProGrade" line, imported from a ISO 9001-certified factory in China, features a nickel-plated matrix to resist corrosion—ideal for drilling in Kenya's coastal regions, where saltwater can degrade uncoated bits. For budget-conscious buyers, their "ValueLine" bits offer reliable performance at a lower cost, making them popular with small construction firms and agricultural co-ops.

What makes NWDS stand out is its commitment to customer service. They offer free delivery within Nairobi for orders over Ksh 50,000 and same-day shipping to Mombasa and Kisumu. They also provide technical support, with a team of geologists on call to help clients ｓｅｌｅｃｔ the right bit for their project. "We don't just sell bits—we help our customers get the job done," says Michael Otieno, NWDS's operations manager. "If a client isn't sure whether to use a surface set or impregnated bit, we'll visit their site and make a recommendation."

Based in Mombasa, Kenya's second-largest city and a major port, Mombasa Rock Tools Traders (MRTT) has built a reputation as the coastal region's leading supplier of surface set core bits. Founded in 2008, MRTT serves clients from Lamu to Malindi, focusing on industries like coastal construction (resorts, ports), coral reef research, and salt mining in the Makueni and Kilifi regions.

MRTT's specialty is surface set core bits designed for marine and coastal environments. Their "CoastalShield" series features a stainless-steel body and sealed bearings to prevent saltwater intrusion, making them perfect for drilling near the ocean or in brackish water. They also stock a range of small-diameter bits (as small as 25mm) used by marine biologists to study coral reef composition and by geologists mapping coastal erosion patterns.

As a trader, MRTT partners with international brands like Boart Longyear and Atlas Copco, importing premium surface set core bits for clients who demand top-tier performance. For example, their Boart Longyear "TuffMaster" bits are a favorite among large mining companies operating in the coastal mineral sands projects, where they drill through tough sandstone and clay with minimal wear. MRTT also offers wholesale pricing for local hardware stores and drilling contractors, with a loyalty program that rewards repeat buyers with discounts.

Kenya Mining Equipment Solutions (KMES) caters specifically to the mining industry, a sector that relies heavily on precise core sampling. With offices in Nakuru and Turkana, KMES supplies surface set core bits to gold mines in Kakamega, soda ash mines in Magadi, and oil exploration projects in Turkana. Their focus on mining means they understand the unique demands of the industry: high-volume drilling, durability in abrasive rocks, and compliance with international standards like ISO 13503-2 (core drilling for mineral exploration).

KMES's flagship product is the "MinePro" surface set core bit, engineered with a thick matrix (12mm) and extra diamond density (50 carats per crown) to withstand the abrasive conditions of mining. These bits are designed to drill up to 500 meters without needing replacement, reducing downtime for mining operations. "In mining, time is money," says David Kiprono, KMES's technical director. "Our MinePro bits last 30% longer than standard bits, which translates to significant cost savings for our clients."

As a wholesaler, KMES offers bulk pricing for mining companies, with minimum orders starting at 50 bits. They also provide on-site training for drill operators, teaching them how to maintain bits for maximum lifespan. Clients include Base Titanium (Kwale mineral sands mine) and Lake Turkana Wind Power, which used KMES bits to drill foundation holes for wind turbines through hard volcanic rock.

Nestled in the heart of the Great Rift Valley in Nakuru, Rift Valley Drilling Components (RVDC) has been serving the region's drilling needs since 2010. The Rift Valley is home to some of Kenya's toughest geology—volcanic basalt, gneiss, and quartzite—so RVDC specializes in surface set core bits built for hard rock drilling. Their bits are used by geothermal energy companies (like KenGen, which drills for steam in Olkaria), agricultural co-ops (drilling irrigation wells), and construction firms (building roads and bridges across the valley).

RVDC's "RiftHard" surface set core bits are a local favorite. They feature a proprietary matrix blend of tungsten carbide and cobalt, which resists chipping and wear when drilling through hard rock. The bits also have a unique "step-cut" design, with diamonds arranged in staggered rows to reduce friction and heat buildup—a critical feature in the Rift Valley's high-temperature geothermal fields. "We test our bits in the Olkaria geothermal fields, where temperatures reach 300°C," says Jane Njeri, RVDC's founder. "If they can handle that, they can handle anything Kenya throws at them."

RVDC operates as both a manufacturer and wholesaler, producing 300 bits monthly in their Nakuru workshop and distributing them to clients across the Rift Valley and beyond. They offer flexible wholesale terms, including payment plans for small businesses, and stock a range of sizes from NQ (47.6mm) to HQ (63.5mm), the most commonly used sizes in regional drilling projects.

Serving Western Kenya from its base in Kisumu, Lake Victoria Drilling Gear (LVDG) focuses on the unique needs of the region's agricultural and fishing communities. Western Kenya is known for its fertile soils, but access to water for irrigation is often limited. LVDG's surface set core bits help drill shallow to medium-depth wells (50-200 meters) through the region's mix of clay, sandstone, and granite, supporting smallholder farmers and fish farms around Lake Victoria.

LVDG's "FarmPro" surface set core bits are designed for affordability and ease of use, making them ideal for small-scale drillers. These bits are smaller (mostly BQ and NQ sizes) and feature a simplified design that reduces costs without sacrificing quality. For example, their "Economy" FarmPro bits use recycled diamond grit from larger industrial bits, lowering the price by 20% compared to new diamonds. "Small farmers can't afford expensive bits," explains Peter Ochieng, LVDG's sales manager. "Our FarmPro line lets them drill a well for under Ksh 100,000, which pays off in higher crop yields."

As a wholesaler, LVDG partners with agricultural co-ops and government programs like the National Irrigation Board, supplying bits at bulk rates for community water projects. They also offer free training workshops for local drillers, teaching them basic bit maintenance to extend lifespan. In 2023, LVDG supplied over 1,000 bits to a World Bank-funded project that drilled 500 irrigation wells in Siaya and Busia counties, benefiting over 10,000 farmers.

Kenya Diamond Bits Industries (KDBI) is a relative newcomer, founded in 2018, but it has quickly made a name for itself with innovative surface set core bit designs. Based in Athi River, KDBI combines local manufacturing with global technology, using computer-aided design (CAD) software to optimize diamond placement and matrix composition for maximum efficiency.

KDBI's standout product is the "SmartCut" surface set core bit, which uses sensors embedded in the bit's matrix to monitor temperature and wear in real time. The data is transmitted to a mobile app, alerting drill operators when the bit needs sharpening or replacement. While this technology is more expensive, it's popular with large construction firms and mining companies that want to minimize downtime. "Traditional bits require operators to guess when they're worn out," says James Mwangi, KDBI's tech lead. "SmartCut takes the guesswork out, saving time and money."

KDBI operates as a manufacturer and wholesaler, with a focus on high-tech, high-performance bits. They supply to clients like the Kenya National Highways Authority (KeNHA), which uses SmartCut bits to drill soil samples for road construction projects, and international mining firms with operations in Kenya. While their prices are higher than some competitors, KDBI's bits are backed by a 1-year warranty, a rarity in the industry.

Coastal Core Tools Wholesalers (CCTW) is Mombasa's largest dedicated wholesaler of surface set core bits, with a 10,000 sq. ft. warehouse that stocks over 20,000 bits from brands like Schramm, Sandvik, and their own in-house label. Founded in 2015, CCTW serves the coastal region and beyond, with clients in Tanzania and Uganda thanks to its strategic location near the port of Mombasa.

CCTW's strength is its product range. They offer everything from budget-friendly imported bits (starting at Ksh 5,000) to premium European-made bits (up to Ksh 50,000) for specialized projects. Their best-selling imported line is the "GlobalCore" series from a Chinese manufacturer, which balances quality and price for mid-sized contractors. For clients who need the best, they stock Sandvik's "UltraCore" surface set bits, which feature synthetic diamonds for maximum hardness and are used in deep mining and oil exploration.

As a wholesaler, CCTW prides itself on fast shipping and flexible payment terms. They offer 30-day credit to registered clients and can deliver to Dar es Salaam (Tanzania) or Kampala (Uganda) within 3 days. They also buy and sell used bits, refurbishing them for resale at discounted prices—a popular option for small drillers on a tight budget. "We believe in sustainability," says Amina Mohammed, CCTW's manager. "Refurbishing used bits reduces waste and gives small businesses access to quality tools they might not otherwise afford."
