Exploration Engineering Drilling Diamond Core Drill Bits 60mm 75mm

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

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

1. 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.

2. Water Well Drilling

   • BX series for boreholes in arid regions (Sahel, East Africa).

3. Infrastructure

   • NX bits for foundation piling (Lagos skyscrapers, Ethiopian dams).
