Nestled in the coastal city of Bergen, Bergen Drilling Solutions (BDS) has built a reputation as Norway's go-to wholesaler for surface set core bits and drilling accessories. What started as a small family-owned business now supplies clients across Scandinavia, with a warehouse network spanning Oslo, Trondheim, and even Stockholm, Sweden. BDS prides itself on "one-stop shopping"—offering not just core bits, but also drill rods, reaming shells, and core barrels, making it a convenient partner for small to mid-sized drilling companies.

BDS's surface set core bit catalog is extensive, with options for every budget and project type. Their BasicLine bits are popular among construction firms for soil sampling in road-building projects, offering reliable performance at an affordable price. For mining operations, the MineralMaster series features surface-set diamonds with a high concentration, designed to cut through hard rock like granite and gneiss with minimal wear. One standout product is their EcoCore bit, which uses recycled carbide in its matrix body—a choice that aligns with Norway's strict environmental regulations and appeals to eco-conscious clients.

Customer service is another area where BDS shines. The company offers 24/7 technical support, with a team of engineers available to help clients ｓｅｌｅｃｔ the right bit for their formation. "Last winter, we had a client in Tromsø struggling with a surface set core bit that kept clogging in clay," recalls Ingrid Olsen, BDS's customer service manager. "Our team overnighted a custom-tipped bit with wider water channels, and they were back to drilling by morning. That's the level of support we strive for."

Stavanger Diamond Tools (SDT) may be newer to the scene than some competitors, but it has quickly become a powerhouse in the surface set core bit market, particularly for offshore applications. Founded by a team of former oilfield engineers, SDT specializes in high-performance bits designed for the extreme conditions of the North Sea. Their flagship product, the OffshoreXtreme surface set core bit, features a unique "tapered diamond" design that reduces vibration during drilling, extending bit life by up to 30% compared to standard models.

SDT's manufacturing facility in Stavanger is state-of-the-art, equipped with 3D printing technology to prototype new bit designs in days rather than weeks. This agility allows them to customize bits for clients with unique needs, such as a recent project for a Norwegian oil company requiring a core bit that could withstand temperatures of 150°C and pressures of 10,000 psi. The result? A surface set core bit with a heat-resistant matrix and diamond segments bonded with a proprietary alloy, which exceeded the client's performance expectations.

As a trader, SDT also partners with international manufacturers to distribute specialized core bits not produced locally, such as PQ3 diamond bits for deep geological drilling and surface set core bits with electroplated diamond segments for delicate sampling. "We believe in offering the best of both worlds—our own high-end bits and curated products from global leaders," says CEO Erik Nilsen. "This approach ensures our clients never have to compromise on quality, no matter how niche their project."

Trondheim Exploration Gear (TEG) has deep roots in Norway's scientific community, having supplied core bits to the Norwegian Geological Survey (NGU) and universities like NTNU for over 40 years. Based in Trondheim, a hub for research and innovation, TEG specializes in surface set core bits for precision sampling—critical for geological studies that require intact, contamination-free rock samples.

TEG's GeoPrecise surface set core bit line is a favorite among researchers. These bits feature ultra-fine diamond particles set in a flexible matrix, which minimizes damage to the core sample during extraction. For paleontological digs, where preserving fossilized remains is paramount, their FossilGuard bits use a low-impact cutting action that reduces vibration. One notable project TEG supported was the 2020 Svalbard Ice Core Expedition, where their custom-designed surface set core bits helped extract 300-meter ice samples dating back 10,000 years.

Beyond manufacturing, TEG is a leading trader of specialized drilling accessories, importing hard-to-find tools from countries like Germany and the United States. Their partnership with a German diamond manufacturer allows them to offer surface set core bits with synthetic diamonds, which are more consistent in size and hardness than natural diamonds—ideal for controlled laboratory experiments.

"Our mission is to support discovery," says Dr. Helga Bjørnsen, TEG's chief geologist. "Whether it's a student studying rock formations in the Jotunheimen Mountains or a team searching for rare earth minerals in Finnmark, we provide the tools that turn curiosity into data."

Tromsø Rock Bits (TRB) is a testament to Norwegian innovation in extreme environments. Located above the Arctic Circle, TRB was founded by a group of engineers frustrated by the lack of surface set core bits designed for polar conditions. Today, the company is a global leader in cold-weather drilling tools, with clients in Alaska, Canada, and Russia.

TRB's ArcticDrill surface set core bits are engineered to perform in temperatures as low as -40°C. They feature a special lubricant that doesn't freeze, and their diamond segments are bonded with a flexible matrix to prevent cracking in brittle permafrost. For coastal projects, such as building offshore wind farms in the Barents Sea, their CoastalGuard bits resist saltwater corrosion and can drill through mixed formations of sand, clay, and bedrock.

What makes TRB unique is its focus on research partnerships. The company works closely with the University of Tromsø's Arctic Technology Center to test new materials, such as graphene-reinforced matrix bodies, which could extend bit life in icy conditions by 50%. "We don't just react to industry needs—we anticipate them," says founder Sven Eriksson. "The Arctic is changing, and so are the tools needed to explore it responsibly."

Ålesund Core Systems (ACS) has carved a niche in underwater drilling, serving clients who need to extract core samples from lake beds, fjords, and coastal seabeds. Based in Ålesund, a city with a rich maritime history, ACS combines traditional craftsmanship with modern technology to create surface set core bits that perform in aquatic environments.

ACS's MarineCore surface set core bits are waterproof, with sealed bearings and corrosion-resistant coatings to prevent saltwater damage. For underwater archaeology projects, such as exploring Viking shipwrecks in the Trondheimsfjord, their HeritageGuard bits use a low-torque design that minimizes disturbance to delicate artifacts. One of their most innovative products is the WindFarmBit , developed for installing offshore wind turbine foundations—it can drill through compacted sand and gravel at depths of 50 meters with minimal vibration, protecting marine life.

ACS also offers training programs for drill operators, teaching them how to adjust surface set core bit parameters (like rotation speed and weight on bit) for underwater conditions. "Drilling underwater is a whole different challenge," says marine engineer Lars Pettersen. "Currents, visibility, and pressure all affect performance. We don't just sell bits—we teach people how to use them effectively."
