Main Features
1) Reliability
The piston of DTH Hammer uses the special (imported) high nickel alloy steel, with advanced heat treatment as military industry standard.
Strengthening processing on hammer surface for higher were-resistance.
2) Suitability
Specially designed drill bits for middle soft and hard rock formations. Easily disassembly thread for easy maintenance.
3) Efficiency
Extra-short structure design DTH 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 air tightness design.
