Related Product Features:
  • Compatible with T38, T45, and T51 thread systems for versatile drilling applications.
  • Features wrench flats to simplify the coupling and decoupling process during extension drilling.
  • Available in both hexagonal and round cross-sections to suit different drilling needs and efficiency requirements.
  • Hexagonal rods offer superior rigidity, energy transfer, and increased flushing capabilities.
  • Round rods are lighter and ideal for extension drilling applications where weight is a consideration.
  • Manufactured from high-quality carbon steel and tungsten carbide for exceptional wear resistance and long service life.
  • Produced using specific CNC processing equipment and scientific straightening to ensure consistent product quality.
  • Rigorous quality controls guarantee that each drill rod meets performance expectations in tunnelling, mining, and quarrying.
FAQs:
  • What thread systems are available for these drill rods?
    Our drill rods are compatible with a range of thread systems including R22, R25, R28, R32, R38, T38, T45, T51, ST58, and T60, providing versatility for various drilling rigs and applications.
  • What are the main differences between hexagonal and round drill rods?
    Hexagonal rods are more rigid, heavier, and transfer energy more efficiently while increasing flushing, making them suitable for demanding conditions. Round rods are generally lighter and are typically used in extension drilling applications where reduced weight is beneficial.
  • What materials are used in the manufacturing of these drill rods?
    The drill rods are manufactured from high-quality carbon steel and tungsten carbide, which provide superior wear resistance and extend the service life of the tools in tough mining and tunnelling environments.
  • What quality control measures are in place for these products?
