The Matair H/D Industrial Riveter is a heavy-duty pneumatic riveting tool designed for high-volume fastening applications in construction, fabrication, and automotive work. Featuring a specially profiled 3-piece jaw set machined from high-grade tool steel, it delivers 1420 kg traction power with a stroke length of 18 mm and operates on just 0.11 CFM (3 LPM) air consumption. The extra-long lever mechanism and croken mandrel vacuum absorption system reduce fatigue and maximise efficiency on downward riveting operations.
