ABSTRACT:
A ball device for setting blind rivets is provided. The device features one or more rows of balls of at least three balls per row, and a taper section which cooperates with the balls to grip the mandrel of the blind rivet. Upon movement of the taper section, the balls dig into the mandrel to grip, and consequently pull the mandrel in the desired direction. The device features a longer life than similar devices utilizing jaws to grip the mandrel.
