⚙️ Product Description

DTH Hammer is widely used in geotechnical engineering, with various hardness and high hardness levels. Hard rock with poor toughness has the following characteristics: reasonable material selection, advanced manufacturing technology, and perfect quality assurance.

  • Higher penetration rate for efficiency.
  • Hardening treatment to prolong service life and reduce costs.
  • Large single impact force with low power consumption during crushing.
  • Excellent power transmission through optimized piston and weight design.
  • Modern structural theory for longer stress waves and lower stress amplitude.

CIR90 DTH Hammer Medium and High Pressure DTH Impactor is ideal for Open-pit and Underground Mines, marble quarrying, water well drilling, and other engineering construction projects.
