The 5-inch DTH (Down-The-Hole) hammer is a powerful drilling tool widely used across industries for efficiently creating boreholes in tough geological contexts.
By delivering high-frequency impacts to a drill bit, these hammers fracture rock or soil while effectively removing debris through the hole. They find essential applications in mining for blast holes, construction for foundation and utility drilling, geothermal projects, water well drilling, oil exploration, quarrying, foundation engineering, and environmental sampling.
The hammers’ adaptability and efficiency make them indispensable tools for precise and effective drilling in a range of challenging scenarios.
