Jackhammer

Get your day hammering away with a jolt of sound from the job site. A jackhammer is a large percussive drill powered by compressed air. It is mainly used to drill rock and pavement. It works similar to a hammer and chisel, by jabbing with its bit repeatedly into an object. Jackhammers are dangerously loud and an ear covering must be worn at all times by the operator to prevent hearing damage. Prolonged exposure to the vibration of the tool can cause blood-circulation failures in the fingers, a condition known as white finger. Jackhammer usage can also increase the chance of developing carpal tunnel syndrome.
