A top hammer system transfers approximately 84% of the energy to the drill bit, while a down-the-hole (DTH) hammer is more efficient in this regard—almost 100% of the energy is being transferred [ 12][ 13]. WebMar 25, 2024 · In top hammer drilling, the activity is concentrated at the top of the drill string, above the hole, as a hammer transmits cyclical shock waves to the drill bit by applying a percussive force on the drill rods or tubes (With DTH drills, the hammer is placed down-the-hole at the bit). fadily camara bébé
