Specification:

Feature:

• Designed with two concentric steel walls (inner and outer tubes) for maximum strength and rigidity.

• Provides high resistance to deformation, making it suitable for hard rock layers and deep foundation drilling.

• Ensures better alignment and stability of boreholes during drilling operations.

• Longer service life due to stronger structure, even under heavy-duty working conditions.

• Equipped with robust connection systems (bayonet lock or screw type) for safe and efficient assembly.

• Supports use with casing oscillators or rotators, allowing effective drilling in challenging soil and rock formations.

• Available in various diameters, customized to match different drilling rigs and project requirements.

• Reusable and durable, offering cost savings in long-term, large-scale construction projects.
