Top 10 TSP Core Bit Suppliers, Manufacturers, Wholesalers and Traders in Philippines

When it comes to TSP core bits in the Philippines, PDTC is the name that industry veterans trust. Established in 1998, this Manila-based manufacturer has built a reputation for durability—something they attribute to their in-house production facility in Laguna, where they craft everything from standard TSP bits to specialized options like the nq impregnated diamond core bit . What sets PDTC apart? Their focus on R&D. They work closely with local mining companies to test bits on Philippine rock formations, ensuring their products hold up in even the toughest conditions, like the andesite rocks of Benguet or the limestone of Palawan.

PDTC's product line is impressive, covering all major core bit types: from the hq impregnated drill bit (ideal for deep geological surveys) to surface set bits for softer formations. They also offer custom solutions—if you need a bit with specific diamond concentration or matrix hardness, their engineers will tailor it to your project. For wholesalers, PDTC provides bulk pricing and flexible delivery schedules, making them a top choice for distributors across Luzon and Visayas. Clients rave about their after-sales support too; their technical team is available 24/7 to help troubleshoot drilling issues, which is a lifesaver when you're stuck in the field.

RockSolid Drilling Supplies, based in Cagayan de Oro, has made a name for itself by focusing on both quality and accessibility. Since 2005, they've catered to a mix of large construction firms and small-scale miners, offering a balanced range of TSP core bits and related tools. Their claim to fame? The t2-101 impregnated diamond core bit , a bestseller designed for fast penetration in medium-hard rock—perfect for infrastructure projects like road construction or water well drilling in the Visayas region.

Unlike some suppliers who import generic bits, RockSolid partners with Taiwanese and Chinese manufacturers to produce custom-ordered bits that meet Philippine standards. They also stock a wide range of accessories, from core barrels to reaming shells, making them a one-stop shop for drillers. What clients love most is their transparent pricing—no hidden fees, and bulk discounts start at just 50 units, which is great for small to medium contractors. Plus, with warehouses in Manila, Cebu, and Davao, they can deliver to most project sites within 48 hours, a huge advantage in a country with challenging logistics.

MCTI is the go-to for high-end projects, especially in the oil and gas sector. Founded in 2010, this supplier specializes in matrix body PDC bits and premium TSP core bits, with a client list that includes major players in the Malampaya gas field and geothermal projects in Batangas. Their secret? Using imported diamond grit from Belgium and strict quality control—each bit undergoes 10+ hours of testing in their Quezon City lab before shipping.

While MCTI's prices are on the higher side, clients say the investment pays off. Their hq impregnated drill bit , for example, has a longer lifespan than competitors, reducing downtime in deep exploration. They also offer technical training for drill operators, ensuring your team knows how to get the most out of their bits. MCTI's market focus is primarily large-scale projects, but they've recently expanded their wholesale program to support smaller distributors, making their premium bits more accessible to the wider market.

As the leading TSP core bit supplier in the Visayas, Cebu Drilling Solutions has carved a niche by understanding regional needs. Established in 2002, this family-owned business started as a small trader but grew quickly by prioritizing customer service. Today, they import high-quality bits from South Korea and China, focusing on affordability without compromising on performance. Their bestsellers include the nq impregnated diamond core bit (a hit with small-scale miners in Bohol) and standard TSP bits for construction projects in Cebu and Iloilo.

What makes Cebu Drilling Solutions stand out is their flexibility. They offer "mix and match" bulk orders—so you can buy 20 NQ bits, 10 HQ bits, and 5 surface set bits in one shipment, ideal for contractors juggling multiple projects. They also provide on-site demos: if you're unsure which bit to use, their team will visit your project site, analyze the rock samples, and recommend the best option. With a warehouse in Mandaue City and delivery partners across Visayas and Mindanao, they ensure you get your bits when you need them—even to remote areas like Siargao or Camiguin.

Wait, didn't we already talk about RockSolid? No, this is a different company—RockSolid Drilling Supplies (note the space) is based in Davao City and focuses on Mindanao's booming mining sector. Established in 2015, they've quickly gained traction by offering rugged bits designed for the region's mineral-rich but challenging geology, like the nickel laterites of Surigao and the chromite deposits of Zamboanga. Their star product? A heavy-duty TSP core bit with extra diamond impregnation, built to withstand the high abrasion of Mindanao's ultramafic rocks.

RockSolid Davao also understands that many Mindanao projects are in remote areas, so they've invested in a fleet of delivery trucks and partnered with local couriers to ensure on-time shipments. They stock the t2-101 impregnated diamond core bit , a favorite among geologists for its precision in mineral sampling, and offer competitive pricing for bulk orders. Their small but dedicated team prides itself on personalized service—call them, and you'll likely speak directly to the owner, who can offer expert advice on bit selection.

LDT has been a staple in Luzon's drilling scene since 1995, with a focus on large-scale mining and government projects. Based in Baguio City (close to the mining hubs of Benguet and Zambales), they've built strong relationships with major players like Philex Mining and Lepanto Consolidated. LDT's strength lies in their vertical integration—they not only supply TSP core bits but also manufacture their own diamond segments, ensuring consistent quality. Their hq impregnated drill bit is a industry standard for deep exploration, with a design that reduces heat buildup, a common issue in the high-temperature geothermal fields of Laguna and Batangas.

While LDT primarily serves big clients, they also work with wholesalers, offering attractive margins for those distributing to smaller contractors. They're known for their strict quality control—every bit undergoes a 3-point inspection before leaving the factory: hardness testing, diamond distribution checks, and simulated drilling trials. If a bit fails in the field (which is rare), LDT offers a replacement guarantee, a policy that has earned them trust over the decades.

Visayas Core Supplies, based in Iloilo City, is all about accessibility. Founded in 2008, this wholesaler focuses on making TSP core bits and related tools available to small and medium contractors across the Visayas. They import bits from trusted manufacturers in China and India, curating a range that balances quality and cost. Their most popular product? The standard surface set core bit, which is perfect for construction projects like building foundations or road cuts, where speed and affordability matter most.

Visayas Core Supplies doesn't just sell bits—they educate their clients too. Their website features a handy guide to core bit selection, explaining when to use an nq impregnated diamond core bit vs. a surface set bit, and they host free workshops for contractors in Cebu, Bacolod, and Tacloban. They also offer flexible payment terms, a big help for small businesses with cash flow constraints. With a focus on building long-term relationships, they've become the go-to supplier for many local governments in the Visayas, who rely on their timely deliveries for public infrastructure projects.

For contractors in the metro and nearby provinces, Metro Manila Drilling Parts is a convenient one-stop shop. Located in Quezon City, this retailer and wholesaler stocks a wide range of TSP core bits, from budget-friendly imported options to premium local brands like PDTC. What makes them popular? Their walk-in store, where you can inspect bits in person before buying—great if you're in a hurry and need to check diamond exposure or matrix condition. They also carry all the accessories you might need: core barrels, reaming shells, and even drill rod adapters.

Metro Manila Drilling Parts caters to small contractors and individual drillers, so their minimum order quantities are low—you can buy a single nq impregnated diamond core bit or a bulk pack of 50. They also offer same-day delivery within Metro Manila, a lifesaver for emergency repairs. While they don't manufacture their own bits, they carefully vet suppliers to ensure quality, and their staff is knowledgeable enough to help you pick the right bit for your project, whether it's a small water well in Rizal or a construction site in Cavite.

As a newer entrant (established in 2018), PET is shaking up the market with innovative designs and competitive pricing. Based in Calamba, Laguna, this manufacturer focuses on lightweight yet durable TSP core bits, using advanced matrix materials that reduce bit weight without sacrificing strength. Their flagship product is a modified t2-101 impregnated diamond core bit with a unique water channel design, which improves cooling and chip removal—ideal for high-speed drilling in soft to medium-hard formations, like the sandstone of Ilocos or the shale of Bicol.

PET is also big on sustainability. They use recycled steel in their bit bodies and have a take-back program for worn bits, which they recycle into new matrix materials. While they're still building their market share, they've gained attention from environmental exploration companies, who appreciate their eco-friendly approach. PET offers free samples to new clients, so you can test their bits before committing to a bulk order—a risky move for a small company, but one that shows confidence in their product.

Rounding out our list is Mindanao Diamond Drills, a Davao-based wholesaler that specializes in serving the agricultural and mining sectors of Mindanao. Established in 2015, they focus on affordable yet reliable TSP core bits, with a particular emphasis on water well drilling—an area critical to Mindanao's agriculture. Their most popular bit? A budget-friendly nq impregnated diamond core bit that's perfect for drilling through the volcanic tuff and alluvial deposits common in irrigation projects across Cotabato and Bukidnon.

Mindanao Diamond Drills partners with Chinese manufacturers to keep costs low, but they inspect every shipment in-house to ensure quality. They also offer training sessions for local farmers and small-scale drillers, teaching them how to properly maintain bits to extend lifespan. With delivery hubs in Davao, Cagayan de Oro, and General Santos, they're able to reach even remote farming communities, helping to boost agricultural productivity in the region.
