Brief: Need quick answers about practical use? This video highlights the essentials. Watch as we demonstrate how Impregnated Diamond Core Bits deliver efficient drilling in hard rock mining exploration. You'll see a detailed walkthrough of their cutting mechanism, stabilization features, and how to select the right bit based on rock hardness and abrasiveness for optimal performance.
Related Product Features:
  • Impregnated with high-quality synthetic diamonds evenly mixed in a metal alloy matrix for continuous sharp cutting.
  • Matrix erodes at the same rate as diamonds wear, exposing new sharp diamonds to maintain cutting efficiency.
  • Features wing-like stabilizer fins, buttons, or inserts to prevent wobbling and ensure a straighter borehole.
  • Includes flush ports for irrigation and removal of cuttings, enhancing drilling performance and bit longevity.
  • Manufactured using vacuum brazing or high-pressure sintering for maximum diamond-to-metal bond durability.
  • Economical choice for most geological formations compared to other core bit types.
  • Comes with a core bit choice chart to match rock type, hardness, and abrasiveness for precise selection.
  • Designed for hard rock mining exploration, ensuring reliable performance in challenging conditions.
FAQs:
  • How do impregnated diamond core bits maintain their cutting efficiency?
    The metal alloy matrix erodes at the same rate as the diamonds wear, continuously exposing new sharp diamonds to cut through the rock, ensuring sustained performance.
  • What stabilization features are included to ensure straight drilling?
    The bits are equipped with wing-like stabilizer fins, buttons, or inserts that support and guide the bit body, preventing wobbling and promoting a straighter borehole.
  • How do I select the right diamond core bit for my rock type?
    Refer to the core bit choice chart provided, which matches rock hardness and abrasiveness to the appropriate bit hardness number (e.g., BST 1/3 for soft rock, BST 14 for ultra-hard rock).
  • What manufacturing methods are used for these diamond bits?
    They are produced using vacuum brazing or high-pressure sintering, which fuses diamonds into the metal substrate at a microscopic level for enhanced durability and bond strength.
