Down-the-hole drilling (DTH) involves a drilling hammer at the bottom of a drill string. It utilizes three essential elements for efficient hole drilling: bit loading (weight), rotation, and air. These components work together to effectively crush rock formations.
Located at the tip of the drillstring, drill bits typically consist of two or three cones constructed from the hardest available materials, including steel, tungsten carbide, and synthetic or natural diamonds. These materials provide the sharp teeth necessary for cutting through rock.
