Top 10 Carbide Core Bit Suppliers, Manufacturers, Wholesalers and Traders in Papua New Guinea

Founded in 2005, PNG Drilling Solutions Ltd. has grown from a small workshop in Port Moresby to the country's leading manufacturer of carbide core bits. What sets this company apart is its commitment to local production—over 70% of its carbide core bits are manufactured in-house at its Lae-based facility, reducing reliance on imported products and ensuring faster turnaround times for clients. "We started because we saw a gap in the market," says John Tovua, the company's operations manager. "Mining companies were waiting months for core bits from overseas, and often they didn't fit the specific rock conditions here. Now, we can design a custom HQ impregnated drill bit for a client in the Highlands and have it ready in a week."

PNG Drilling Solutions specializes in bits for mining and geological exploration, with a focus on durability in PNG's diverse rock formations—from the soft clays of the Sepik Basin to the hard granite of the Owen Stanley Range. Its NQ impregnated diamond core bits are particularly popular among exploration teams, thanks to their ability to retain sharpness even after drilling through abrasive volcanic rock. The company holds ISO 9001 certification, and all its products undergo rigorous testing at its on-site laboratory, where engineers simulate extreme drilling conditions to ensure performance.

Beyond manufacturing, PNG Drilling Solutions prides itself on customer support. It operates a 24/7 technical hotline, and its team of geologists and drilling experts regularly visits client sites to provide on-the-ground advice. "Last year, a team at the Wafi-Golpu copper-gold project was struggling with core recovery in a fault zone," Tovua recalls. "We sent a technician up there, analyzed the rock samples, and modified our carbide core bit design to include a reinforced matrix. Within days, their core recovery rate jumped from 60% to 92%." With clients including Barrick Gold and Newcrest Mining, PNG Drilling Solutions has solidified its reputation as a trusted partner for PNG's mining industry.

For construction and infrastructure projects across PNG, Lae Industrial Tools Wholesalers is the go-to name for reliable carbide core bits and drilling accessories. Established in 1998, this family-owned business has built its success on one simple principle: never run out of stock. "In construction, downtime costs money," explains Maria Sato, the company's purchasing director. "If a contractor is drilling foundations for a school in Lae and their surface set core bit wears out, they can't wait a week for a replacement. That's why we keep over 5,000 carbide core bits in our warehouse at any time—from small 38mm bits for soil sampling to large 150mm bits for bridge pilings."

Lae Industrial Tools' inventory isn't just large—it's diverse. In addition to carbide core bits, the company stocks road milling cutting tools, trencher cutting tools, and excavator bucket teeth, making it a one-stop shop for construction crews. Its surface set core bits, which feature diamond particles embedded in a metal matrix, are a favorite for urban projects like the Lae Port Expansion, where precision and speed are critical. "Surface set bits are great for concrete and soft rock," Sato notes. "We recently supplied 200 of them to the team building the new Lae-Highlands Highway bypass, and they reported finishing the drilling phase two weeks ahead of schedule."

What truly distinguishes Lae Industrial Tools is its logistics network. With warehouses in Lae and Port Moresby, and partnerships with local transport companies, it offers next-day delivery to most major cities and two-day delivery to regional hubs like Madang and Goroka. For urgent orders, the company even operates a small fleet of delivery vans in Lae, ensuring contractors get the tools they need when they need them. "Last month, a client in Kundiawa called at 4 PM needing a carbide core bit for a road repair project starting at dawn," Sato laughs. "We loaded it onto our van, and it was there by 7 AM the next day. That's the service we're known for."

When it comes to hard rock mining, few suppliers in PNG can match the expertise of Port Moresby Mining Supplies (PMMS). Founded in 2010 as a joint venture between local entrepreneurs and Australian drilling equipment manufacturer Boart Longyear, PMMS specializes in high-performance tools for extreme drilling conditions—including its signature impregnated core bits. "Hard rock mining in PNG isn't for the faint of heart," says David Kama, PMMS's sales manager. "The rocks here are tough, the temperatures are high, and the pressure is relentless. Our impregnated core bits are designed to handle all three, with a diamond concentration that stays sharp even when drilling through porphyry copper deposits."

PMMS's product lineup includes a range of carbide core bits and TCI tricone bits, but it's the company's focus on innovation that sets it apart. In 2022, it launched a new line of carbide core bits with a "self-sharpening" matrix, which exposes fresh diamond particles as the bit wears down—a game-changer for deep mining projects where bit changes are time-consuming. The company also offers custom bit design services, working with clients to create tools tailored to specific rock types. "A gold mine in the Enga Province was struggling with a layer of quartzite that was destroying their standard bits," Kama explains. "We adjusted the diamond size and matrix hardness, and now their bits last three times longer. It's all about understanding the geology."

PMMS's partnership with Boart Longyear gives it access to global technology, but the company remains deeply rooted in PNG. It employs over 50 local staff, including 10 engineers trained in Australia, and invests in community projects like drilling water wells for rural villages near its Port Moresby warehouse. "We believe in giving back," Kama says. "Our success is tied to PNG's success." With clients like Harmony Gold and the Ok Tedi Mining Limited, PMMS has become a key player in supporting PNG's hard rock mining sector, proving that quality and local commitment can go hand in hand.

Operating in the remote highlands of PNG comes with unique challenges: rugged terrain, limited infrastructure, and long distances from major cities. Highlands Exploration Equipment (HEE), based in Mount Hagen, was founded in 2012 specifically to address these challenges. "Exploration teams in places like the Southern Highlands or Simbu Province can't just pop down to a hardware store for a new NQ impregnated diamond core bit," says Sarah Wai, HEE's founder. "That's why we built our business around mobility and customization."

HEE's fleet of mobile service units—equipped with spare parts, repair tools, and a small inventory of core bits—travels to remote mining camps and exploration sites, providing on-the-spot support. "We recently spent three weeks in the Star Mountains, supporting a gold exploration project," Wai recalls. "Their drill rig broke down 100 kilometers from the nearest road, and their surface set core bits were worn out. We drove our 4x4 up there, repaired the rig, and supplied new bits—all while camping in the bush with their team. That's the HEE difference."

The company's product range is tailored to remote projects, with a focus on lightweight, durable tools. Its NQ impregnated diamond core bits are designed for portability, weighing 30% less than standard models without sacrificing strength. HEE also offers custom bit designs, working with geologists to create tools optimized for specific exploration targets. "A client in the Western Province was looking for a core bit that could handle both sandstone and basalt in a single hole," Wai explains. "We modified our carbide core bit with variable diamond concentrations—denser in the basalt zone, lighter in the sandstone—and it worked perfectly."

HEE's commitment to remote areas has earned it a loyal following among small to mid-sized exploration companies and community mining cooperatives. The company also partners with NGOs to support sustainable mining practices, offering training workshops on safe drilling techniques and proper bit maintenance. "In PNG, exploration isn't just about finding minerals—it's about empowering local communities," Wai says. "We're proud to be part of that."

Madang, a coastal city on PNG's north coast, is a hub for marine drilling projects—from offshore oil exploration to coastal infrastructure like ports and seawalls. Madang Drilling Technologies (MDT), founded in 2008, specializes in tools designed to thrive in these corrosive, saltwater environments. "Saltwater is the enemy of drilling equipment," says Robert Lau, MDT's technical director. "A standard carbide core bit will rust and fail within weeks in marine conditions. Our HQ impregnated drill bits are coated with a special corrosion-resistant alloy, and we use stainless steel components in all our coastal-focused tools. That's why companies like ExxonMobil trust us for their offshore projects."

MDT's product lineup includes carbide core bits, DTH drilling tools, and drill rods, all engineered for marine and coastal use. Its surface set core bits, for example, feature a nickel-plated matrix to prevent saltwater pitting, and its diamond segments are bonded with a heat-resistant adhesive to withstand the friction of drilling through coral reefs and sedimentary rock. The company also imports high-quality bits from Asian manufacturers like China's Shanghai Shenkai, allowing it to offer competitive pricing without compromising on quality.

Beyond product sales, MDT provides training for coastal drilling crews, teaching them how to maintain tools in saltwater environments and troubleshoot common issues like bit clogging. "We recently trained a team from the Madang Port Authority on how to use our carbide core bits for dredging surveys," Lau says. "They were struggling with bits getting stuck in soft sediment, so we showed them how to adjust their drilling speed and use a flushing system. Now they're completing surveys 50% faster." With a focus on innovation and coastal expertise, MDT is helping drive PNG's marine infrastructure and exploration projects forward.

For small-scale miners, local construction crews, and community projects in the Highlands, affordability is often as important as quality. That's where Mount Hagen Tools & Hardware (MHTH) comes in. Founded in 2010, this family-run business has made it its mission to provide reliable carbide core bits and drilling tools at prices that small operators can afford. "We started because we saw too many local miners using cheap, imported bits that broke after a few hours," says James Yawari, MHTH's owner. "They'd spend their hard-earned money on tools that didn't work, and then they couldn't afford to finish their projects. We wanted to change that."

MHTH's inventory includes a range of budget-friendly options, from basic carbide core bits for soil sampling to more advanced surface set core bits for small-scale gold mining. The company sources its products directly from manufacturers in India and Vietnam, cutting out middlemen to keep costs low. "Our standard 50mm carbide core bit sells for K150, which is half the price of imported brands," Yawari notes. "And we stand behind every bit—if it fails within 30 days, we ｒｅｐｌａｃｅ it for free."

Despite its focus on affordability, MHTH doesn't skimp on quality. All its bits undergo basic testing in-house, and the company works with local mechanics to repair and recondition used bits, giving them a second life at even lower prices. "A lot of small miners can't afford new bits, so we take their old ones, re-tip the carbide, and sell them for K50," Yawari explains. "It's good for their wallets and good for the environment."

MHTH also offers bulk discounts for community groups and cooperatives, making it a popular choice for projects like village water wells and small-scale road construction. "Last year, we supplied 20 carbide core bits to a women's mining cooperative in the Western Highlands," Yawari says. "They used them to drill test holes for alluvial gold, and now they're earning enough to send their kids to school. That's the impact we want to have." With its focus on community and affordability, MHTH has become a trusted name in the Highlands' small-scale industries.

Rabaul, located on the island of New Britain, is surrounded by active volcanoes—making it a hotspot for geothermal exploration and volcanic rock drilling. Rabaul Drilling Supplies (RDS), founded in 2015, has carved out a niche as the expert in tools designed for these challenging conditions. "Volcanic rock is unpredictable," says Dr. Lisa Kila, RDS's chief geologist and founder. "One minute you're drilling through soft ash, the next you hit a layer of solid basalt with gas pockets. Standard bits just can't handle that variability. Our impregnated core bits are engineered to adapt—they're tough enough for basalt but flexible enough to avoid breaking in ash layers."

RDS specializes in heat-resistant drilling tools, including carbide core bits with ceramic-reinforced matrices and diamond segments that can withstand temperatures up to 300°C—critical for geothermal projects where drill holes can reach hot springs and steam vents. The company's heat-resistant carbide core bits are used by organizations like the PNG Geothermal Energy Development Company (GEDC) in their exploration of sites like the Ramu Graben geothermal field.

In addition to geothermal work, RDS supports volcanic hazard mapping projects, supplying surface set core bits to teams studying lava flows and volcanic soil composition. "Last year, we worked with the University of Papua New Guinea to drill cores from the 1994 Rabaul eruption deposits," Kila recalls. "The ash was so fine that standard bits kept clogging. We modified our surface set core bit to include wider flutes for better flushing, and they were able to extract intact samples for the first time."

RDS also offers training on volcanic drilling safety, teaching crews how to recognize signs of gas buildup and adjust drilling parameters to avoid accidents. "Drilling near volcanoes is risky," Kila says. "We don't just sell bits—we help keep people safe." With its unique focus on volcanic and geothermal drilling, RDS has become an invaluable resource for scientists and energy companies working in PNG's most geologically active regions.

Gold and copper mining in the Highlands requires tools that can withstand the region's hard, abrasive rock—and Goroka Mining & Construction Ltd. (GMCL) has been supplying those tools since 2001. Based in Goroka, the capital of the Eastern Highlands Province, GMCL has built a reputation for durability, with its NQ impregnated diamond core bits and carbide core bits being a staple at mines like Porgera and Lihir. "In gold mining, core quality is everything," says Michael Boga, GMCL's sales manager. "A single poor core sample can lead to misinterpreting a deposit, costing millions. Our bits are designed to deliver clean, intact cores, even in the toughest conditions."

GMCL's NQ impregnated diamond core bits are particularly renowned for their precision. The company uses a proprietary matrix that balances hardness and toughness, ensuring the bit retains its shape while drilling through quartz-rich rock—common in gold deposits. "Quartz is brutal on bits," Boga explains. "It wears them down quickly and can cause core fracturing. Our matrix is designed to grind through quartz without overheating, so the core stays intact."

Beyond selling bits, GMCL offers on-site bit reconditioning services, sending technicians to mine sites to re-tip and repair used carbide core bits. "A new bit costs K1,000, but reconditioning costs K300 and extends the bit's life by 60%," Boga notes. "Mines love it because it cuts their tooling costs significantly." The company also stocks PDC cutters and drill rods, making it a one-stop shop for mining operations.

GMCL's commitment to the mining industry extends to training. It partners with the PNG University of Technology to offer courses on drill bit maintenance and rock mechanics, helping local miners improve their skills. "We recently trained 20 drillers from the Porgera Gold Mine on how to properly align their core bits," Boga says. "After the training, their bit life increased by 25%. It's all about working together to make mining more efficient." With its focus on quality and innovation, GMCL has become a key supplier for PNG's gold and copper mining sectors.

Oil and gas exploration in PNG's offshore and onshore basins demands the highest standards of reliability—and Kimbe Coastal Drilling Traders (KCDT) delivers just that. Founded in 2005 and based in Kimbe, on the island of New Britain, KCDT specializes in API-certified drilling tools, including carbide core bits and matrix body PDC bits designed for the extreme pressures of oil well drilling. "Oil companies can't afford failures," says Peter Toka, KCDT's operations director. "A stuck bit in a 5,000-meter well can cost hundreds of thousands of dollars in downtime. That's why we only supply bits that meet API 7-1 standards—the strictest in the industry."

KCDT's oil PDC bits are a standout product, featuring advanced cutter placement and a matrix body that withstands the high torque and temperature of deep drilling. The company imports these bits from leading manufacturers in the United States and Europe, but also works with local engineers to adapt them to PNG's unique geology. "The Papuan Basin has layers of shale and limestone that can cause bit balling," Toka explains. "We modified our PDC bits with a 'cleaner' design—wider watercourses and anti-ballooning cutters—to prevent clay buildup. It's made a huge difference for our clients."

In addition to oil PDC bits, KCDT stocks a range of carbide core bits for exploration wells, including specialized models for directional drilling. The company's surface set core bits are popular for shallow gas exploration, thanks to their ability to drill quickly through unconsolidated sediment. KCDT also offers technical support, with a team of petroleum engineers on call to advise clients on bit selection and drilling parameters.

KCDT's client list includes major players like ExxonMobil and Santos, and the company has been involved in key projects like the PNG LNG expansion. "We supplied the carbide core bits for the Hides gas field appraisal wells in 2021," Toka says. "Those wells reached depths of 3,500 meters, and our bits performed flawlessly. It's a testament to the quality of the tools we provide." With its focus on API standards and technical expertise, KCDT is helping drive PNG's oil and gas industry forward.

In Wewak, a coastal town in East Sepik Province, Wewak Industrial Supplies (WIS) is making a name for itself by supporting sustainable infrastructure and agriculture projects. Founded in 2014, this socially conscious business specializes in carbide core bits and drilling tools for rural development—from irrigation wells to village road construction. "We believe that good tools should build communities, not just profits," says Anna Wapau, WIS's founder. "That's why we focus on products that help smallholder farmers, local governments, and NGOs create lasting change."

WIS's surface set core bits are a favorite for rural water projects, as they're affordable and easy to maintain—critical for communities with limited technical expertise. The company also stocks trencher cutting tools for laying irrigation pipes and small-diameter carbide core bits for soil sampling in agricultural projects. "A farmer in the Sepik Plains needed to drill a 100-meter well for his rice paddies," Wapau recalls. "He'd never used a core bit before, so we sent a technician to train him and supplied a basic carbide core bit. Now he's irrigating 5 acres of rice and selling surplus to his village. That's the impact we want."

What sets WIS apart is its commitment to sustainability. The company sources its bits from manufacturers with strong environmental credentials, and it recycles used carbide tips to reduce waste. It also offers a "drill for water, plant a tree" program—for every carbide core bit sold, WIS donates K5 to local reforestation efforts. "We've planted over 10,000 trees in the Sepik region since 2018," Wapau says. "It's our way of ensuring that development doesn't come at the expense of our environment."

WIS's clients include NGOs like World Vision and Oxfam, as well as provincial governments. The company also partners with local agricultural cooperatives, offering training on water well drilling and tool maintenance. "Last year, we trained 30 farmers in the East Sepik on how to use our surface set core bits to drill shallow wells," Wapau explains. "Now they're self-sufficient—no more waiting for outside help when their wells need repair." With its focus on sustainability and community, WIS is proving that drilling tools can be a force for good in rural PNG.
