Product Description
Product Overview
BX (60mm) and NX (75mm) Diamond Core Bits are engineered specifically for Africa's most demanding drilling challenges in mining, water well, and geotechnical applications. These high-performance bits deliver superior core recovery, extended service life, and cost-effective drilling operations - essential for Africa's mineral exploration and infrastructure development projects.
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) |
Key Features & Benefits
Unmatched Hard Rock Performance
- Premium Synthetic Diamonds: High-concentration diamond segments for granite, basalt, and kimberlite formations
- Reinforced Matrix Bond: Resists wear in abrasive formations including quartzite and copper ore
- Anti-Balling Design: Prevents clogging in clay-rich laterite soils common in West Africa
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 operations
Cost Efficiency
- 2-3× Longer Lifespan vs. conventional bits - reduces downtime and replacement costs
- High Core Recovery (>95%) - critical for accurate mineral assessment and resource evaluation
Applications in Africa
Mining & Exploration
- Gold & Diamonds: Kimberlite drilling in Angola and Botswana, hard-rock gold in Mali and Tanzania
- Copper & Cobalt: NX bits for DRC/Zambia's Copperbelt region
- Coal: BX bits for Mozambique and Tanzania coal deposits
Water Well Drilling
- BX series for boreholes in arid regions including Sahel and East Africa
Infrastructure Development
- NX bits for foundation piling in major projects including Lagos skyscrapers and Ethiopian dams
