Rivet Buster Jumbo Air Hammer – 11" Stroke Pneumatic, D & P Handle

The Madido Rivet Buster is a Jumbo (11X) pneumatic air hammer built in Montreal for cutting rivets, shearing bolts and demolishing steel and concrete. With an 11" stroke, a 720 BPM blow rate and a body weighing about 34 lb, it delivers the impact of a much heavier breaker in a tool one person can control all shift. Available with a closed D handle (models 4111 and 1133) or an open P handle (model 4111).

Originally designed for removing rivets from steel bridges and structures, the rivet buster is now a go-to tool for steel demolition, tank cutting and concrete breaking. It takes standard Jumbo (11X, .866" hex) rivet buster steel, so you can fit moil points, chisels, punches and pin drivers.
