Rotary air blasting is the most common shallow drilling method, in which a piston-driven hammer-like object drives the drill bit into the rock, fragmenting the hard surface into chips that are then lifted to the surface via compressed air.
Rotary air blasting saves a considerable amount of time than other techniques but the equipment and compressors needed for it occur far exceeds the alternatives. Advantages includes the following:
1. Economic and cost-effective
2. Increased penetration
3. Long-lasting bit life
