77mm HTW Diamond Reaming Shell

  1. Size and Specification:
    • Outer diameter of 77mm, suitable for HTW series drilling operations.
  2. Material and Construction:
    • Made with high-quality natural or synthetic diamonds embedded in a highly resistant matrix. The steel body has threads for connecting to the drill bit and core barrel.
  3. Main Functions:
    • Enlarges the hole to maintain the required diameter.
    • Stabilizes the drill bit to reduce deviation.
    • Cleans the drill hole to ensure smooth passage of drilling tools and replacement bits.
  4. Application:
    • Widely used in geological exploration, mining drilling, and water well drilling, suitable for various rock formations.
  5. Design Features:
    • Spiral water channels for efficient water flow and cuttings removal.
    • Tungsten carbide inserts on the leading edge for enhanced wear resistance.
    • Conical front edge design for easier entry into the drill hole.
