6’’ HD65A DTH Hammer can be used for drilling a water well borehole or drilling a blasting borehole on the rock in mining manufacturers, 6’’ HD65A DTH Hammer is one of the most popular DTH hammers for drilling a borehole. 6’’ HD65A DTH Hammer (down-the-hole hammer) is a tool that is installed to the end of a drill pipe and drills through hard rocks with compressed air. It’s a kind of small jackhammer that is used to break hard rock into small particles. A DTH hammer can solve the problem of removing hard rock layers in a borehole.

6’’ HD65A DTH Hammer is suitable for drilling bits:φ155mm-φ203mm sizes.
6’’ HD65A DTH Hammer attaches tightly to the end of a drill pipe by screws, it’s air-powered with a high cyclic rate; Because a DTH hammer is pneumatically powered, it has air exhaust holes that blow the stone chips and dust out from the borehole. Small portable borehole drill rigs equipped with a DTH hammer can drill through rocks as quickly as large truck borehole drill rigs do.
