Faqs:
  • What is the working principle of the 89mm Mring Overburden Concentric Casing Drilling System?
    The system works by welding the ring bit and casing shoe assembly to the casing before drilling. The pilot bit's upper shoulder engages the casing shoe, transferring percussive energy to crush rock and advance the casing. After drilling, the drill string is retrieved by reverse rotation, leaving the ring bit in the hole.
  • What are the key benefits of using this drilling system?
    The system offers rapid drilling speeds, efficient energy transfer, and easy retrieval of the drill string. It reduces overall drilling time and is compatible with various hammer shank styles, making it versatile for different engineering applications.
  • What after-sale services are provided with this product?
    The manufacturer offers technical support, free replacement for quality-related failures, and a responsive sales team that addresses inquiries within 24 hours (excluding holidays).
