Riveter nose sizes. The riveter on the left is the powerful Astro 1426, the one on the right is a typical riviter. Make sure in advance that you can use the big riveter with a Monel rivet. In several instances I found that the nose on the big tool wouldn't fit, like on one end of a typical clam cleat. So use the smaller tool with an aluminum rivet on the tight side and the big tool with a Monel rivet where you have room.
