Down-the-hole (DTH) hammer bits are used with DTH hammers for drilling holes through various rock types. They feature a splined drive system that rotates the bit during ground penetration.
DTH drilling involves a hammer at the bottom of the drill string that combines bit loading (weight), rotation, and air to efficiently crush rock formations.
