Product Descriptions
Designed for high-efficiency and precision drilling in applications such as geological exploration, oil drilling, mining, and construction. With outstanding wear resistance, stable drilling performance, and extended service life, our diamond drill bits have become the preferred choice for customers worldwide.
Technical Specifications
| Parameter | NX Series (75mm) | BX Series (60mm) | Remarks (SEA Applications) |
| Diameter | 75mm (2.95") | 60mm (2.36") | BX suits lighter rigs common in SEA mines |
| Recommended RPM | 150-350 RPM | 200-450 RPM | Higher RPM for BX in softer formations |
| Weight | ~4.5kg | ~3.2kg | BX preferred for handheld/portable rigs |
| Applicable Rock Types | Granite, Basalt, Hard Sandstone | Limestone, Shale, Soft-Medium Sandstone | NX for volcanic areas (Indonesia, PH) |
| Drilling Depth | Up to 300m+ (deep coring) | Up to 150m (shallow exploration) | BX for coal/iron ore in Vietnam, Myanmar |
| Bit Life | 80-120m in hard rock | 50-80m in medium rock | Longer life reduces downtime in remote sites |
| Hydraulic Pressure | 50-80 Bar | 30-60 Bar | Lower pressure for BX saves energy costs |
Advantages for Southeast Asia
BX Series:
Ideal for coal, limestone, and soft mineral exploration (common in Vietnam, Thailand).
Lightweight for mobile rigs in jungle/remote areas.
Faster ROI in shallow-depth projects.
NX Series:
Dominates hard-rock drilling (Indonesia, Philippines).
Superior heat resistance for tropical high-RPM operations.
Corrosion-resistant coatings for coastal/marine surveys.
Regional Adaptability:
Both series support high-humidity and abrasive sediment conditions.
Optional anti-balling designs for clay-rich layers
NX ,BX Core Bits Application
Diamond drill bits are indispensable tools in modern drilling operations, offering unmatched precision, durability, and efficiency across multiple industries. Below are their key applications:
1. Geological Exploration & Mineral Prospecting
Core Sampling: Used to extract intact rock cores for analysis of mineral deposits (e.g., gold, copper, iron ore).
Resource Estimation: Critical for defining ore body dimensions and grades in mining projects.
SEA Relevance: Widely deployed in Indonesia (nickel/gold), Vietnam (bauxite), and Myanmar (jade).
2. Oil & Gas Drilling
Exploratory Wells: Diamond-impregnated bits drill through hard formations (e.g., granite, basalt) to reach reservoirs.
Directional Drilling: Maintain precision in complex well paths.
Advantage: Outlasts traditional PDC bits in abrasive strata.
3. Mining & Quarrying
Blast Hole Drilling: Prepares sites for explosives in open-pit mines (e.g., coal in Thailand, tin in Malaysia).
Underground Mining: Compact BX-series bits fit confined spaces.
4. Construction & Civil Engineering
Foundation Piling: Drills into bedrock for high-rise buildings and bridges.
Tunnel Boring: Used in metro projects (e.g., Singapore, Manila).
Utility Installation: Creates precise holes for pipelines and cables.
