In top hammer drilling, percussive force is applied at the top of the drill string, transmitting shock waves through the drill rods to the bit. This differs from DTH drilling where the hammer is located down-the-hole at the bit.
Rock drilling tools are used for oil and gas exploration, mining, construction, and industrial operations requiring excavation through natural rocks, concrete, and masonry.
Percussion drilling is a manual technique where a hammering bit attached to a cable is lowered into an open hole, creating impact forces to break through materials.
