DTH hammers are widely used in areas such as open-pit and underground mining, irrigation, bridge and tunnel, infrastructure, slope anchorage, geological exploration, petrol and natural gas engineering. Drilling holes diameter range of our DTH hammers is from 64mm to 1020mm.
Features:
1. The hole size range is wide and the hole straightness is high.
2. The impactor impacts at the bottom of the hole, and the working environment noise is greatly reduced.
3. It is applied to rock formations above medium-hard, with high drilling efficiency.
4. Drilling rigs and drilling tools are more portable.

1.Reliability：
Piston uses the special (imported) high nickel alloy steel, with advanced heat treatment as the military industry standard.
Strengthening processing on the hammer surface for higher wear-resistance.
2.Suitability：
Specially designed drill bits for medium-soft and hard rock formations
Easily disassembly thread for easy maintenance.
3.Efficiency：
Extra-short structure design hammer and bit for great efficiency of high impact energy transmission, with high impact power and fast drilling rate Hammer and bit design are optimized by computer simulation, with best air distribution chamber and airtightness design.
