Pneumatic rock drills are widely used in fields such as mining, tunnel excavation, building demolition, and foundation engineering. In mining operations, pneumatic rock drills are used to drill blast holes in hard rocks for blasting operations. In tunnel excavation, pneumatic rock drills are used to drill tunnel contours in rock or concrete for subsequent construction work. In building demolition and foundation engineering, pneumatic rock drills are used to break and demolish concrete structures, providing convenience for construction.

The working principle of pneumatic rock drills is relatively simple and efficient. It utilizes the high-pressure airflow generated by the air compressor to be transported through pipelines to the cylinders inside the rock drill. When compressed air enters the cylinder, it pushes the piston forward, which in turn drives the chisel head to impact and break rocks or concrete. This high-frequency impact allows rock or concrete materials to be quickly crushed and chiseled open, thereby achieving the purpose of drilling or crushing.
