Thread 2 3/8'' API REG Abrasive Rock 4'' SD4 Drill Hammer For Mining

Product introduction:

A down-the-hole drill, usually called DTH by most professionals, is basically a mini jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small flakes and dust and is blown clear by the air exhaust from the DTH hammer. The DTH hammer is one of the fastest ways to drill hard rock. Now smaller portable drilling rigs with DTH hammers can drill as fast as much larger truck rigs with this newer technology.
