BX & NX Diamond Core Drill Bits – for African Drilling Conditions
Product Overview
BX (60mm) and NX (75mm) Diamond Core Bits are engineered for Africa's toughest drilling challenges in mining, water well, and geotechnical applications. Designed for high performance in hard rock formations, these bits deliver superior core recovery, extended bit life, and cost-effective drilling – critical for Africa's mineral exploration and infrastructure development.
Technical Specifications
| Parameter | BX Series (60mm) | NX Series (75mm) | Africa Advantage |
| Diameter | 60mm (2.36") | 75mm (2.95") | BX for narrow holes, NX for standard coring |
| Drilling Depth | Up to 150m | Up to 300m | NX for deep mineral exploration |
| RPM Range | 400–800 RPM | 300–600 RPM | Optimized for African rock hardness |
| Bit Life | 50–80m (medium rock) | 80–120m (hard rock) | Longer life = lower cost/meter |
| Rock Types | Limestone, shale, coal | Granite, basalt, kimberlite | BX for coal (Mozambique), NX for gold (Ghana) |
Features & Benefits
1. Unmatched Hard Rock Performance
Premium Synthetic Diamonds: High-concentration diamond segments for granite, basalt, and kimberlite (ideal for African gold & diamond mines).
Reinforced Matrix Bond: Resists wear in abrasive formations (e.g., quartzite in South Africa, copper ore in DRC).
Anti-Balling Design: Prevents clogging in clay-rich laterite soils (common in West Africa).
2. Africa-Specific Adaptations
Corrosion-Resistant Steel: Withstands high humidity, acidic groundwater, and saline conditions.
Enhanced Waterways: Ensures efficient coolant flow in dry or water-scarce drilling sites.
Compact & Lightweight: BX series fits portable rigs used in remote/artisanal mining.
3. Cost Efficiency
2–3× Longer Lifespan vs. conventional bits – reduces downtime and replacement costs.
High Core Recovery (>95%) – critical for accurate mineral assessment.
Applications in Africa
Mining & Exploration
Gold & Diamonds: Kimberlite drilling (Angola, Botswana), hard-rock gold (Mali, Tanzania).
Copper & Cobalt: NX bits for DRC/Zambia’s Copperbelt.
Coal: BX bits for Mozambique/Tanzania deposits.
Water Well Drilling
BX series for boreholes in arid regions (Sahel, East Africa).
Infrastructure
NX bits for foundation piling (Lagos skyscrapers, Ethiopian dams).
