Top 10 Electroplated Core Bit Suppliers, Manufacturers, Wholesalers and Traders in Norway

Founded in 1992, Norway Drilling Tools AS (NDT) is a household name in the Norwegian drilling community. Based just outside Oslo, this manufacturer has built its reputation on producing high-performance electroplated core bits tailored to Norway’s unique geological challenges. What sets NDT apart is its in-house R&D team, which works closely with local geologists and mining companies to refine its designs. Their flagship product, the “NordicShield” electroplated core bit, features a thicker diamond layer (up to 2.5mm) and a reinforced steel matrix, making it 30% more durable than standard bits when drilling through hard crystalline rocks—perfect for projects in the Norwegian Highlands.

NDT isn’t just a manufacturer; they also act as a wholesaler, supplying smaller retailers and international clients across Scandinavia. Their commitment to sustainability is another plus: they use recycled steel in their bit bodies and have a zero-waste policy in their electroplating facility. Customers often praise their quick turnaround times—most standard bits ship within 48 hours—and their technical support team, which offers on-site guidance for optimizing bit performance in tricky formations.

Headquartered in Bergen, Nordic Core Bits Ltd has been a key player in the diamond drilling scene since 2005. While they produce a range of drilling tools, their specialty lies in small to medium-sized electroplated core bits ( diameters from 36mm to 113mm), popular among geologists and small-scale mining operations. What makes them a go-to for many is their focus on affordability without compromising quality. Their “BergenLite” series, for example, uses a lightweight aluminum core tube paired with a high-grade electroplated diamond segment, reducing fatigue for drillers while maintaining cutting efficiency.

As a wholesaler, Nordic Core Bits has built strong partnerships with Asian manufacturers, allowing them to offer competitive pricing on bulk orders. They also stock a wide range of core drilling accessories, from reaming shells to core lifters, making them a one-stop shop for smaller projects. Local mining consultant Lars Hansen notes, “For our prospecting trips in the Hardangervidda, we always order from Nordic Core Bits. Their bits hold up well in the gneiss there, and their prices let us stay within budget on tight exploration grants.”

Oslo Mining Supplies (OMS) is a third-generation family business that’s been supplying the Norwegian mining industry since 1978. Starting as a small hardware store in downtown Oslo, they’ve grown into a leading wholesaler and trader of drilling tools, with a particular focus on electroplated core bits for industrial-scale projects. OMS prides itself on its global network—they partner with manufacturers in Germany, Italy, and the US to bring in specialized bits, including large-diameter electroplated core bits (up to 203mm) used in oil well exploration and tunnel construction.

What customers love about OMS is their inventory depth. They maintain a 10,000 sq.m warehouse on the outskirts of Oslo, stocked with over 500 different core bit models, meaning even hard-to-find sizes are available for same-day pickup. Their technical team also offers custom plating services, adjusting diamond concentration and matrix hardness based on specific rock types. “When we needed a custom bit for drilling through marble in the Sørlandet region, OMS worked with us to tweak the diamond density,” says a project manager at a major construction firm. “The result? We finished the job two weeks ahead of schedule.”

Bergen Diamond Tech (BDT) is the innovation leader on this list. Founded in 2010 by a team of materials engineers from the University of Bergen, BDT has made waves with its “SmartPlate” electroplated core bits, which feature embedded sensors that monitor temperature and wear in real time. This tech allows drillers to adjust pressure or speed mid-operation, reducing bit breakage and improving core sample quality—critical for precise geological analysis.

While BDT manufactures its own high-end bits, it also acts as a trader for premium international brands, bringing in specialized electroplated core bits for niche applications like underwater drilling (think subsea oil exploration) and polar research. Their small but dedicated team offers training workshops for clients, ensuring users get the most out of their high-tech bits. “We use BDT’s SmartPlate bits for our Arctic research expeditions,” says a geologist from the Norwegian Polar Institute. “The sensors help us avoid overheating in permafrost, and the core samples are cleaner than anything we’ve gotten with standard bits.”

Nestled in Norway’s tech hub, Trondheim Drilling Components (TDC) has carved a niche as a manufacturer focused on precision. Since 1998, they’ve specialized in electroplated core bits for laboratory and small-scale core sampling, where accuracy is paramount—think university research projects or environmental soil testing. Their “TrondheimPrecise” series offers bits with ultra-fine diamond grit (up to 80/100 mesh), producing core samples with minimal fracturing, which is essential for analyzing delicate rock structures like fossil-bearing sedimentary layers.

TDC also stands out for its commitment to customer collaboration. They offer a “Custom Bit Program,” where clients can specify everything from diamond concentration to shank size, with prototypes ready in as little as two weeks. As a wholesaler, they cater to educational institutions and environmental firms, often offering discounts for bulk orders of small-diameter bits. A geology professor at NTNU Trondheim raves, “TDC’s bits are the reason our student-led mapping projects consistently produce publishable data. The precision is unmatched, and their team is always willing to tweak designs for our unique field sites.”

Stavanger, Norway’s oil capital, is home to Stavanger Exploration Tools (SET), a supplier with deep roots in the energy sector. Founded in 2008, SET initially focused on drilling tools for offshore oil exploration, but has since expanded to serve mining and construction clients. Their electroplated core bits are designed with the harsh North Sea environment in mind—corrosion-resistant coatings, reinforced joints, and heat-dissipating matrix materials make them ideal for both subsea and onshore projects.

SET acts as both a manufacturer and a trader, importing specialized bits from the US and Canada for large-scale oil projects while producing its own line of “NorthSeaTough” electroplated bits for local use. Their 6-inch (152mm) electroplated core bit is a favorite among offshore drillers for its ability to handle saltwater corrosion and hard sandstone formations. “In the North Sea, downtime costs money,” explains an operations manager at a major oil company. “SET’s bits last longer in our wells, and their technical reps know exactly how to adjust our drilling parameters to get the most out of each bit.”

Up in Norway’s far north, Tromsø Rock Bits (TRB) has been serving the Arctic drilling community since 1995. Operating out of a facility just outside Tromsø, this manufacturer understands the unique challenges of drilling in cold climates—frozen ground, permafrost, and remote job sites where equipment reliability is everything. Their “ArcticShield” electroplated core bits feature a low-temperature matrix alloy that stays flexible even in -30°C conditions, preventing brittleness and breakage in icy rock.

TRB is also a trusted wholesaler for northern mining operations, offering bulk discounts on bits and accessories to clients in Finnmark and Svalbard. What really sets them apart, though, is their logistics network: they run monthly supply convoys to remote Arctic sites during the summer months, ensuring drillers don’t run out of bits when roads are passable. “We mine zinc in northern Finnmark, and TRB is the only supplier that can get us bits in winter,” says a mine manager. “Their ArcticShield bits cut through permafrost like butter, and knowing we can count on their deliveries keeps our projects on track.”

Kristiansand Core Drilling (KCD) may be one of the newer players on this list (founded in 2012), but it’s quickly made a name for itself as a trader with a global reach. Based in the southern port city of Kristiansand, KCD imports electroplated core bits from top manufacturers in China, India, and Turkey, offering a wide range of options at competitive prices. Their catalog includes everything from budget-friendly standard bits for general use to high-end precision bits for specialized projects.

What makes KCD popular with small businesses and independent drillers is its user-friendly online platform, where customers can compare specs, request quotes, and track orders in real time. They also offer a “Try Before You Buy” program, sending sample bits for testing before clients commit to bulk orders. “As a one-man drilling crew, I don’t have the budget for trial and error,” says an independent geologist. “KCD let me test three different bits on my last project, and the one they recommended worked perfectly. Now I order all my bits through their website—it’s fast and hassle-free.”

With over 40 years in the business, Ålesund Mining Solutions (AMS) is one of Norway’s oldest drilling tool suppliers. Founded in 1980, this family-owned manufacturer has stuck to its roots: producing heavy-duty electroplated core bits for large-scale mining operations. Their “ÅlesundMax” series is built for high-torque drilling, with thick-walled steel bodies and extra-dense diamond plating (up to 40 carats per bit) that’s ideal for ore extraction in hard rock mines.

AMS also prides itself on its after-sales service, offering bit reconditioning for clients looking to extend the life of their tools. Their workshop in Ålesund can re-plate worn bits, saving customers up to 50% compared to buying new. “We’ve been working with AMS since my father ran the mine,” says a third-generation mining operator. “Their bits are tough enough for our iron ore deposits, and being able to recondition them keeps our costs down. Plus, their team visits our site twice a year to check our drilling setup—you don’t get that kind of service from newer companies.”

Rounding out our list is Larvik Diamond Tools (LDT), a startup that’s shaking up the industry with its tech-driven approach. Founded in 2015 by a group of former oil industry engineers, LDT uses 3D modeling and computer simulations to design electroplated core bits with optimized diamond placement. Their “DigitalCore” bits are engineered to reduce vibration during drilling, resulting in smoother core samples and less wear on drill rigs—a game-changer for projects where precision and equipment longevity matter.

As both a manufacturer and wholesaler, LDT targets forward-thinking clients, from renewable energy firms drilling for geothermal resources to tech startups developing autonomous drilling systems. Their small but agile team can turn around custom designs in weeks, and they offer a subscription-based bulk ordering service for clients with ongoing projects. “We switched to LDT for our geothermal drilling in southern Norway,” says a renewable energy project manager. “Their DigitalCore bits produce cleaner samples, and the data from their simulations helped us adjust our drilling speed—we cut project time by 15%.”
