Explore Our Casing System Solutions
We offer a comprehensive range of casing systems, each engineered for specific applications and geological conditions.
Concentric Casing System：
A robust system that allows for simultaneous drilling and casing. Ideal for ensuring hole integrity in unstable formations with superior straightness.
| Components | Pilot Bit Ring Bit (Reamer) Casing Shoe |
| Key Features | Stable drilling with low vibration Minimal air escape Easy locking/unlocking mechanism |
| Advantages | Achieves excellent hole straightness with low torque Highly effective in complex geology like pebbles Works well in cracks and weathered rock |
| Applications | Water wells Geothermal wells Foundation piles Grouting holes |
Slide Block Casing System：
This versatile system utilizes retractable sliding blocks (wings) that extend for drilling and retract for easy retrieval. Its innovative design delivers speed and reliability.
| Components | Slide Block Bit Casing Shoe |
| Key Features | Hardened surface for exceptional durability Flexible locking/unlocking Compatibility with a wide range of DTH hammers |
| Advantages | High drilling speed Excellent anti-wear properties Optimized structural strength simplifies operation |
| Applications | Water wells Geothermal wells Short micropiles Harbor projects |
Overburden Wing Bit：
A concentric system specifically engineered for casing installation through loose or unstable overburden into bedrock. The wing bits retract inside the casing for easy extraction.
| Components | Wing Bit Assembly Casing Shoe |
| Key Features | Self-actuating wing bit system Efficient flushing design with spiral grooves to effectively clear cuttings |
| Advantages | Delivers rapid penetration without needing reverse rotation Design prevents clogging, even in loose materials |
| Applications | Drilling through overburden into bedrock for various construction projects Well drilling projects |
Eccentric Casing System（ODEX Casing System）：
Features an eccentric reamer bit that swings out to drill a hole larger than the casing, then retracts to allow the casing to advance.
| Components | Pilot Bit Reamer Guide Device Casing Shoe |
| Key Features | Robust design for complex geologies Easy to operate Compatible with various hammer shanks |
| Advantages | Highly adaptable to varied formations Cost-effective Lower vibration makes it ideal for urban and sensitive environments |
| Applications | Medium-sized grouting holes Dam construction Harbor projects |

Frequently Asked Questions
Have questions? We have clear answers. Here we’ve gathered you need to know about our fly cutter reamer—so you can make your purchase with complete confidence.
✔️ Our casing systems are specifically designed for unstable ground conditions, including sand, pebbles, boulders, loose soil, and construction backfill.
✔️ Once you reach a stable rock formation, you retract the inner drill assembly of the casing system. You can then continue drilling into the rock using a conventional DTH drill bit that passes through the installed casing.
✔️ Absolutely. We specialize in providing customized solutions based on your casing pipe dimensions and DTH hammer model. Contact us to discuss your requirements.
