 · The air cools the bit and flushes the cuttings back to the surface. In this method, air from a compressor is injected through the top swivel of a rotary head. As the compressed air returns to the surface, it carries with it rock chips made by the rotating bit. It is used in soft rock materials to about 25 meters deep, or to drill through the top layer of decomposed rock and soil to get a fresh ...
