DTH Hammer 3.5” AT 92 MB
The AT 92 MB DTH hammer can drill holes from 90 mm to 105 mm with high productivity rates. AT 92 MB is used for blasthole, waterwell and geo-technical applications. Its simple construction can provide easy service conditions and long life of use. It uses an advanced valve system that allows piston acceleration to be continued through the entire piston stroke. That characteristic gives high performance and unmatched productivity. The piston’s shape provides strength even in high pressures. The materials used give long life with no perfomance loss. The AT 92 MB uses IR DHD 3.5 drill bits which match together perfectly and provide unmatched productivity.
