Drill Collar

-Purpose: This essential component is engineered to impart significant weight to the drill bit, ensuring it remains in seamless contact with the geological formation. It also provides unwavering stability to the entire drill string, facilitating efficient and effective drilling operations.

2) Material: Forged from high-grade alloy steel, these collars boast remarkable high yield strength, ensuring superior durability and performance under demanding conditions.
3) Weight: Designed to be substantially heavier than standard drill pipes, with a specific gravity of approximately 7.8, guaranteeing the necessary heft for robust drilling.
4) Thread Connections: Available with API Regular or other premium threads, these collars offer adaptable connectivity for a wide array of drilling contexts.

-Features:
1) Spiral grooves integrated for the prevention of differential sticking, enhancing operational continuity and efficiency.
