12” HD1000A DTH hammer (down-the-hole hammer) is a tool that can be installed to the end of a drill pipe and do drilling work. It’s a kind of small jackhammer that is used to break hard rock into small particles. 12” HD1000A DTH hammer is a kind of pneumatic equipment that is powered by compressed air. 12” HD1000A DTH hammer is used for a water well borehole drilling rig or a DTH borehole drilling rig.
A DTH hammer can solve the problem of removing hard rock layers in a borehole.

12’’ HD1000A DTH Hammer is suitable for drilling bits:φ254mm-φ311mm diameter.
It attaches tightly to the end of a drill pipe by screws, it’s air-powered with a high cyclic rate; Because the DTH hammer is pneumatically powered, it has air exhaust holes that blow the stone chips and dust out from the borehole. Small portable drilling rigs equipped with a DTH hammer can drill through rocks as quickly as large truck drilling rigs do.
