The design of bullet teeth is key to their effectiveness. Typically made from high-grade steel, these teeth often incorporate carbide tips, which enhance their hardness and wear resistance. The conical shape reduces drag during operation, allowing the auger to rotate smoothly and penetrate through tough material with less effort. Additionally, many bullet teeth designs include replaceable components, letting operators replace worn-out parts without needing to change the entire auger head.

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.
