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

If you've spent any time in Sierra Leone's mining or construction scene, you know how critical the right tools are. When it comes to geological drilling —whether you're exploring for diamonds, gold, or other minerals—nothing beats a reliable TSP core bit. These specialized tools are designed to cut through hard rock formations cleanly, capturing intact core samples that help geologists and miners make informed decisions. But with so many suppliers claiming to offer the best products, how do you separate the trustworthy ones from the rest? That's where this guide comes in. We've rounded up the top 10 TSP core bit suppliers, manufacturers, wholesalers, and traders in Sierra Leone, breaking down what makes each stand out, their product strengths, and why they've earned a spot on this list.

Why TSP Core Bits Matter in Sierra Leone's Mining Industry

First, let's quickly cover why TSP core bits are such a big deal here. Sierra Leone is blessed with rich mineral resources—diamonds in Kono, gold in Tonkolili, iron ore in Marampa—and extracting these requires precise exploration. TSP core bits , or Thermally Stable Polycrystalline diamond bits, are built to handle the country's diverse geology, from hard granite to abrasive laterite. Unlike standard impregnated diamond core bits , TSP bits can withstand higher temperatures, making them ideal for deep drilling projects where friction heats up the tool. This durability translates to longer bit life, fewer replacements, and lower downtime—key factors when every day on site counts.

But not all TSP core bits are created equal. The best ones balance hardness with toughness, use high-quality diamond impregnation, and are engineered to minimize wear. That's why choosing the right supplier is crucial. A subpar bit can lead to broken cores, slow drilling speeds, and even equipment damage—costing you time and money in the long run.

Top 10 TSP Core Bit Suppliers in Sierra Leone

Let's dive into the list. These companies have earned their reputation through consistent quality, local support, and a deep understanding of Sierra Leone's unique drilling challenges.

1. Sierra GeoTools Ltd.

If you ask any seasoned geologist in Freetown which supplier they trust, Sierra GeoTools is likely the first name that comes up. Founded over a decade ago, this local manufacturer has built a loyal customer base by focusing on drilling accessories tailored to West African geology. Their TSP core bits are a standout—they use a proprietary diamond impregnation process that balances cutting speed with longevity, perfect for the hard, heterogeneous rock found in Sierra Leone's diamond fields.

What really sets them apart, though, is their after-sales service. They offer on-site training for drill operators, helping teams get the most out of their bits, and their warehouse in Freetown stocks a wide range of sizes (from NQ to PQ) for quick delivery. Whether you're a small exploration company or a large mining firm, Sierra GeoTools has the flexibility to meet your needs—no minimum order required, which is a big plus for startups.

2. West Africa Drilling Supplies (WADS)

WADS is a regional heavyweight with offices in Lagos, Accra, and Freetown, making them a go-to for businesses that need cross-border supply chains. While they're a wholesaler (not a manufacturer), they partner with top global brands to bring high-quality TSP core bits to Sierra Leone. Their catalog includes everything from standard TSP bits for soft to medium rock to specialized versions for ultra-hard formations like quartzite.

One thing customers love about WADS is their technical team. Need help choosing between a TSP bit and a regular impregnated diamond core bit ? Their geologists will walk you through the pros and cons based on your project's specifics—depth, rock type, drilling method. They also offer bulk discounts, which is great if you're stocking up for a long-term project. Just note that lead times can be a bit longer for custom orders, so plan ahead!

3. Kono Mining Tech

Based in the heart of Sierra Leone's diamond country, Kono Mining Tech knows a thing or two about tough drilling conditions. This family-owned business started as a small workshop repairing drill bits and has grown into a trusted manufacturer of TSP core bits. Their claim to fame? The "Kono Pro" line, designed specifically for the region's alluvial and hard rock deposits. These bits feature a reinforced steel body to prevent bending in unstable ground and a unique diamond distribution pattern that reduces vibration—critical for capturing intact core samples.

Local miners appreciate that Kono Mining Tech understands their budget constraints. They offer mid-range pricing without skimping on quality, and they're known for quick turnarounds on repairs. If you're working in remote areas like Koinadugu or Bo, they even arrange delivery via local transport networks, so you don't have to worry about logistics.

4. African Core Bits International (ACBI)

ACBI is a trader with a global network, importing TSP core bits from leading manufacturers in China, India, and Europe. What makes them popular in Sierra Leone is their focus on affordability. They source directly from factories, cutting out middlemen, and pass those savings on to customers. Don't let the low prices fool you, though—they rigorously test every batch of bits in their Freetown lab to ensure they meet ISO standards for hardness and wear resistance.

ACBI is a great option if you need a wide range of drilling accessories alongside your TSP bits. They stock everything from reaming shells to core barrels, making them a one-stop shop. Their customer service is also top-notch—they speak Krio and English, which helps avoid miscommunications, and they offer flexible payment plans for larger orders.

5. Freetown Drilling Innovations (FDI)

FDI is the new kid on the block, but they've quickly made a name for themselves with innovative TSP core bit designs. Founded by a team of ex-mining engineers, they specialize in bits for extreme conditions—think deep gold mines in Tonkolili where temperatures and pressure are high. Their "ExtremeCore" TSP bits use a heat-resistant binder that keeps the diamonds secure even when drilling exceeds 200°C, a common issue in Sierra Leone's deeper projects.

While FDI's prices are on the higher side, many customers say the investment is worth it. Their bits last up to 30% longer than standard models, reducing the number of trips to change bits. They also offer custom bit designs—if you're dealing with a unique rock formation, their engineers will work with you to create a tool that fits your exact needs.

6. Marampa Mining Supplies

Named after Sierra Leone's famous iron ore region, Marampa Mining Supplies started by serving the iron ore giants but has since expanded to cater to smaller operations. Their TSP core bits are built for heavy-duty use—thick steel bodies, extra diamond concentration on the crown, and reinforced shanks to handle high torque. They're particularly popular with companies drilling in iron ore deposits, where abrasiveness can wear down standard bits quickly.

What's unique about Marampa is their rental program. If you're not sure which bit size or type you need, you can rent a few options and test them on-site before buying. This is a game-changer for small exploration teams with limited budgets. They also offer maintenance workshops, teaching local technicians how to sharpen and repair bits, which helps reduce reliance on imported services.
