BQ Core Barrel Kit Includes:
| Part Name | Function |
|---|---|
| Head Assembly | Connects and secures the inner tube to the drill string. Guides rotation and fluid flow. |
| Inner Tube | Collects and protects the core sample during drilling. Made of hardened steel or high-grade alloy. |
| Outer Tube | Houses the inner tube; connects to the drill rods and rotates during operation. |
| Core Lifter Case | Holds the core lifter and provides a seating surface. Prevents core from slipping. |
| Core Lifter | Grips and holds the core sample during retrieval. Spring-loaded for firm core capture. |
| Locking Coupling | Secures the outer tube assembly to the drill string. |
| Adapter Coupling | Connects the core barrel to the bit, ensuring secure and efficient torque transmission. |
| Landing Ring (optional) | Helps center the inner tube assembly when landing in the hole. Improves core alignment. |
