Product Description
Product Overview
HQWL 96mm x 63.5mm wireline diamond core bit with 14mm crown height, designed for geological exploration and construction drilling applications. This impregnated diamond bit series covers hardness levels 1-14 to accommodate various rock formations.
Key Features
- Fast penetration rate with specially designed matrix that continuously exposes new diamonds
- Optimized for cost-effective diamond drilling with balanced performance and service life
- Customizable matrix composition based on rock hardness and formation characteristics
- Available in multiple hardness grades (S1-S14) for different geological conditions
Bit Selection Factors
Rock Hardness
Measured using MOHS hardness scale to determine appropriate bit specifications for different mineral formations.
Rock Formations
Classification based on chemistry and structure, with drillability influenced by grain size, hardness, weathering, and fracturing.
Bit Characteristics
Matrix wear rate, gauge dimensions (hole and core), crown height (4mm-14mm standard), and waterway configurations.
Standard Impregnated Core Bit Sizes
| Size | Hole Diameter (mm) | Core Diameter (mm) | Hole Diameter (in) | Core Diameter (in) |
|---|---|---|---|---|
| BQ | 60 | 36.4 | 2.36 | 1.43 |
| NQ | 75.7 | 47.6 | 2.98 | 1.88 |
| HQ | 96.1 | 63.5 | 3.78 | 2.5 |
| PQ | 122.7 | 85 | 4.83 | 3.34 |
Drilling Parameters Optimization
Fluid Velocity
Critical for cooling the bit and removing cuttings. Optimal upward velocity of 10 cm/sec (4 in/sec) for efficient operation.
Rotational Speed Relative to Penetration (RPI)
Ideal RPI range of 200-250 revolutions per inch for optimal bit life and productivity.
Bit Weight
Recommended maximum weight of 2000-2500 psi (1378-1723 N/cm²) to prevent diamond re-impregnation or matrix failure.
