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
