The 1/4" Air Hydraulic Riveter, No. 6420, from AIRCAT, features 3,700 lbs of pull force and is designed to handle both 3/16" and 1.4" steel and aluminum structural rivets, as well as a 3/16" and a 1/4" monobolt. This tool is designed for continuous use and features a convenient on/off switch for AIRCAT's patented mandrel vacuum collection system. The removable mandrel collection bottle can also be removed and emptied. The riveter has a 63/64" stroke length, an over-mold composite grip, and a swivel air inlet for better maneuverability. A built-in silence system helps reduce noise.
