Williams Comfort Products C-422 Rivet Buster

Product Description

The WILLIAMS COMFORT PRODUCTS C-422 is a rivet buster chisel designed for heavy-duty fastener removal and demolition work. Featuring a 3/4 inch flat tip and a 12 inch overall length, this tool delivers concentrated force to shear and drive out rivets in structural steel, ductwork, and fabricated assemblies. It is sized for use with pneumatic chipping hammers and air hammers commonly found in HVAC, plumbing, and general mechanical contracting applications. At 1.08 pounds, the C-422 offers a manageable weight for extended overhead or tight-clearance work without sacrificing driving mass.

The C-422 rivet buster is suited for trade professionals who need a reliable chisel for removing pop rivets, structural rivets, and fasteners in sheet metal or steel assemblies. Typical applications include ductwork disassembly, boiler room work, mechanical room fabrication, and general industrial maintenance. It is sold individually and is a common addition to a field technician tool kit where pneumatic impact tools are in regular use.
