The smaller 5/32" size of this tool is used by every Airstream service center and independent restoration shop.

This high-quality tool fits any standard drill and shaves the corresponding diameter of Olympic Bulb-Tite rivets to give a solid rivet appearance. The finished 5/32" diameter rivets look nearly identical to the original factory-installed rivets on Airstreams and some other aluminum skin trailers. The 3/16" and 1/4" diameter rivets are used in special applications.

The tool features a concave shaving bit and an adjustable depth stop. Once you set the depth stop to the desired depth, the shave bit plunges down on the rivet and shapes the mandrel and head to a perfectly formed dome shape. See additional photos for a parts diagram.

This tool isn't cheap, but if you're installing more than a handful of rivets, it will save you time and frustration. And the finished look is outstanding.
