BX & NX Diamond Core Drill Bits - Engineered 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
ParameterBX Series (60mm)NX Series (75mm)Africa Advantage
Diameter60mm (2.36")75mm (2.95")BX for narrow holes, NX for standard coring
Drilling DepthUp to 150mUp to 300mNX for deep mineral exploration
RPM Range400-800 RPM300-600 RPMOptimized for African rock hardness
Bit Life50-80m (medium rock)80-120m (hard rock)Longer life = lower cost/meter
Rock TypesLimestone, shale, coalGranite, basalt, kimberliteBX 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)
