-It is designed for drilling 90-127mm.
-Diesel powered down-the-hole (DTH) rigs have excellent maneuverability, smaller footprint and the ability to serve multiple locations.
-HW-916 is a trusted machine for mining and construction companies and contractors engaged in presplitting and conventional production blasthole drilling.
In down-the-hole drilling a drill rod is fitted with a hammer at its lower end.
The hammer, which is mounted on the drill bit, is activated through the addition of compressed air and driven into the ground - simultaneously rotating and impacting.
This method is mainly applied for hard to very hard rock and/or for penetrating large boulders.
