How to select the appropriate drill bit according to different construction environments and strata

ニュース 178 Views
In construction and geological exploration, drill bit selection is crucial for efficiency and quality. Consider stratum characteristics, construction environment, and equipment compatibility to choose the best bit.

  1. Based on Stratum Characteristics
    For soft soil like clay or sand, use spiral bits. Their blades remove soil quickly, boosting efficiency. For rock strata, choose based on hardness. Soft rocks like shale or sandstone suit roller cone bits, which crush rocks. For hard granite, diamond bits work best, leveraging their hardness and wear resistance.
  2. Considering Construction Environment
    In tight spaces or noise – sensitive urban areas, pick small, quiet bits, such as thin – walled bits. In open fields or mines where speed matters, opt for large, high – strength bits.
  3. Ensuring Equipment Compatibility
    Different drilling machines need specific bits. Rotary drilling rigs use rotary bits, and down – ザ – hole drills use down – ザ – hole bits. Match bit with equipment torque and speed to avoid damage and inefficiency.
