Crown Shape Applications
- Flat Crown: Versatile for various hardness levels, ideal for single and dual tube drill bits
- Semi-Round Crown: Optimized diamond distribution for medium-hard to hard formations
- Ladder Crown: Prevents hole deviation in medium-hard, broken, or interbedded formations
- Serrated Crown: Enhances drilling rate in hard, dense formations
- Gear Type Crown: Superior performance in harder or dense geological conditions
- Bottom Jetting: Maximizes coring recovery in sedimentary or metamorphic formations
Waterway Configurations
- Standard Type: No discharge hole design for normal formation conditions
- Wide Type: Enhanced waterways for clay, shale, and coal gangue formations
- Turbo Type: Specialized for hard fractured or competent formations
- Wide Turbo Type: Combines wide and turbo features for medium hard fractured formations
- Round Face Discharge Hole: Improves recovery rate in triple core barrel applications
- Slot Face Discharge Hole: High flow capacity minimizes blockage in fractured formations
- Trapezoid Type: Facilitates debris removal and ensures even wear in thick matrix bits
