Engineered for breaking concrete, masonry, and rock. It consists of a heavy-duty steel cylinder chassis containing an internal piston mechanism, an ergonomic D-handle for operator control, and a pointed moil chisel bit secured at the nose by a high-tension shock-absorbing spring retainer. High-pressure compressed air enters through the threaded inlet coupling beneath the handle, providing the immense fluid power necessary to drive the internal mechanics under rigorous field conditions.
Operationally, when the operator depresses the throttle trigger, high-pressure air flows into the main cylinder through a reciprocating valve system. This valve rapidly alternates the airflow to drive an internal piston forcefully back and forth thousands of times per minute. Each downward stroke delivers a high-velocity impact directly onto the shank of the chisel bit, transferring massive kinetic energy into the target material to fracture it efficiently, while the external coiled spring absorbs the residual structural vibration and retains the bit.
