Faqs:
  • What is a DTH hammer?
    A Down-the-hole (DTH) hammer is a drilling tool located at the bottom of a drill string, combining bit loading, rotation, and air to efficiently crush rock for borehole drilling.
  • What are mining drill bits made of?
    Mining drill bits are typically made of hard materials like steel, tungsten carbide, or synthetic/natural diamonds, designed to cut through rock efficiently.
  • How does a DTH system work?
    A DTH system involves a hammer at the drill string's bottom, using weight, rotation, and air to crush rock. It transmits energy directly for efficient drilling.
