ABSTRACT:
A rivet body is formed with cutting teeth in a forward edge of the rivet body. A mandrel is formed at a forward end with an enlarged head having a drill point thereon. A plurality of the rivet bodies are stacked on the mandrel, with the drill point. The rivet body is rotated and, through rotative coupling, the mandrel is also rotated. The rotating drill point forms pilot holes in workpieces, and the rotating cutting teeth enlarge the pilot holes to form holes for receipt of a cylindrical portion of the lead rivet body.
