The Rivet Buster was originally designed to cut rivets off metal structures. Today the Rivet Buster series is widely known for its tough, powerful tools. They have the ability to perform all types of medium to heavy demolition work. With half the weight of the 60 lb. class paving breakers, the ratio of thier high impact energy versus their weight make them the most efficient tool APT makes. The model 133 meets the weight requirements for bridge deck repair work, and are also popular for cutting up underground tanks.
