QL60 Shank (6”) DTH Bits and Hammers

Product Overview

Down-the-Hole (DTH) bits and hammers are essential equipment for DTH drilling, a method used for drilling large and deep holes in various rock and earth formations. The DTH hammer, driven by compressed air, delivers percussive forces to the DTH bit, which breaks the rock into small fragments. The QL60 series is known for its high efficiency and durability, making it a preferred choice for mining, geological exploration, and water well drilling.
