Two-wing PDC anchor drill bits | Half-piece PDC drill bits | Soft-medium hard formation of f≤8 |
Complete-piece PDC drill bits | Medium-hard formation of f≤10 | |
Reinforced PDC drill bits | Hard formation of f≤15 | |
Triple-wing PDC anchor drill bits | Half-piece PDC drill bits | Hard formation of f≤15 |
Reinforced half-piece PDC drill bits | Hard formation of f≤16 | |
