Cluster DTH Hammer

Product Introduction

A rotation drill rig, air compressor and the “DTH drill string” are the essential unit for DTH drilling while the “DTH drill string” is always made up of DTH drill rods, DTH hammer and DTH bits.
As one of key component, the DTH hammer acts as a role of converting the air pressure to the impact energy, simultaneously transferring impact energy and rotation force to DTH bits.

Low Air Pressure DTH Drilling Hammer Bits
Apply for engineering hole such as drilling blasting hole, guardrail hole in mines, quarries, expressway, the mountain barrier inforcement, anchorage, geothermal air conditioning hole, well-drilling hole etc.
