DTH (Down-The-Hole) Hammer Bits


DTH (Down-The-Hole) Hammer Bits

DTH hammer bits are available in two primary types: Interchangeable Bits and Shank Types. Each type has distinct features and applications.

Interchangeable Bit:

  • Features: Designed for easy replacement, only the head of the bit needs to be changed, not the entire bit.
  • Advantages: Facilitates quick bit head changes, reducing downtime and costs. Adaptable to various geological conditions with different bit heads.
  • Applications: Ideal for use in diverse geological conditions, particularly when rapid bit changes are necessary on-site.

Shank Type:

  • Features: The shank type bit is a one-piece design, integrating the shank and the bit. The shank connects the hammer to the bit, transmitting the hammer's impact to the bit.
  • Advantages: Provides high strength and stability due to its one-piece construction. Delivers powerful impacts through its integrated design.
  • Applications: Best suited for high-strength rock or extremely hard geological conditions where powerful impacts are required.

Each type of DTH hammer bit is selected based on specific job conditions and requirements. Interchangeable bits offer flexibility for various conditions, while shank types provide stability and strength for demanding environments.
