The DTH hammer operates through a system of compressed air. High-pressure air is directed down the drill string, powering the hammer at the end of the drill bit. The hammer strikes the bit with considerable force, fracturing the rock immediately beneath it. As the bit penetrates further, the broken rock is then cleared from the hole by the same air stream, allowing for continuous drilling without the interruptions often associated with other drilling methods.

DTH drilling refers to a method where the drilling bit is located at the end of a drill string, below the surface of the ground. This technique is distinguished by the use of high-performance percussion hammers, which are positioned on the drill bit. DTH drilling involves the use of compressed air to deliver rapid impacts, breaking rock into smaller fragments. This method is particularly effective in hard rock formations, making it a preferred choice for mining operations and various drilling applications.
