Installed on the pneumatic leg, utilizing the support and propulsion effects of the pneumatic leg to reduce the operator's labor intensity. Rock drilling has high efficiency and can drill deep blast holes, widely used in mining and construction fields. Specially used for drilling upward boreholes, mainly for rock drilling operations in mining areas and courtyards. Its telescopic design allows the rock drill to adapt to drilling needs at different angles.

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, thereby driving the chisel head to collide and impact hard materials such as rocks or concrete. This impact can quickly break and break open rocks, achieving the purpose of drilling or crushing.
