Pneumatic drilling machines, often referred to as air drills, operate on the principle of converting compressed air energy into rotational force. The process begins when compressed air is supplied from an external compressor to the machine's motor. This air pressure causes the internal components to rotate, thereby driving the drill bit. The speed and torque can be adjusted based on the specific task, allowing for precision control in various materials, from soft woods to hard metals.
