    Precision-Engineered Locking Couplings

    Di-Corp provides a complete line of locking couplings engineered to integrate seamlessly with our core retrieval tools. Through extensive field testing and ongoing development, these couplings have consistently demonstrated performance that exceeds customer expectations. Drillers Edge locking couplings are designed to deliver:

    • Precision machined threading for compatibility with all common thread forms, including the latest S-Maxx design.
    • Standardized sizing in B, N, H, and P to suit a wide range of drilling setups.
    • Outer tubes in 5-foot (1.5 m) and 10-foot (3 m) lengths; full hole options are compatible with extended core barrel assemblies.
    • Tang or non-tang coupling configurations to meet various operational requirements.

    Features & Benefits

    • Expanded contact area helps minimize hole deviation and enhances target accuracy.
    • Reduced in-hole vibration improves core barrel stabilization.
    • Fully compatible with all existing core barrel components for seamless integration.
    • Wear-resistant latching surface extends the life of each locking coupling.
    • Proven performance across soft, medium, and very hard formations and fractured and competent ground conditions.
    • Suitable for a wide range of drilling applications.

    Full Hole Locking Couplings Benefits

    Full hole locking couplings offer design-specific advantages that enhance performance, including:

    • Three-flat geometry that maintains a straighter outer tube, improving core barrel stabilization while drilling.
    • High-quality alloy steel for exceptional durability and extended life.
    • Precision extruded geometry to ensure product consistency across all couplings.
    • Heat-treated outer surface for enhanced wear resistance in demanding conditions.

    Frequently Asked Questions

    What are locking couplings used for?

    Locking couplings secure the head assembly of a core barrel to the drill rod, acting as an adapter between the core barrel outer tub and the rod. Additionally, locking couplings stabilize the core barrel’s upper section, helping reduce the hole deviation and providing backup to the reaming shell.
