Câu hỏi thường gặp:
  • What is a DTH Bit?
    Down-the-hole (DTH) hammer bits are used with DTH hammers for drilling through various rock types. They feature a splined drive for rotating the bit in the ground, ensuring efficient drilling.
  • What is a DTH hammer?
    A DTH hammer is a drilling tool located at the bottom of a drill string. It relies on bit loading, rotation, and air to crush rock efficiently, making it ideal for hard rock drilling.
  • How does DTH drilling work?
    DTH drilling involves a hammer at the bottom of the drill string that breaks rock into small cuttings. These cuttings are then evacuated by air, water, or drilling mud, ensuring smooth and efficient drilling operations.
