A sonic drill is much more simply known as a rotary-vibratory drill. It’s capable of high drilling speeds along with carrying out tasks, such as continuous coring that can not be done by any other equipment. A sonic drill rig looks like a conventional air or mud rotary drill rig. The greatest difference is within the drill head which is slightly greater than a standard rotary head. The head supplies the mechanism needed for rotary motion, in conjunction with an oscillator, which in turn causes a high frequency force to become superimposed around the drill string. The drill bit is physically vibrating up and down in addition to being pushed down and rotated. These three combined forces allow drilling to proceed rapidly through most geological formations including most types of rock.
