The Rivet Buster .401 Shank with 5/8" blade width is a pneumatic hammer chisel attachment used in aircraft maintenance, structural repair, and heavy industrial disassembly work. It is designed specifically for removing (shearing) solid and driven rivets, typically AN470 universal head or similar aerospace rivets, from metal structures.

This tool is installed into a .401 Parker taper shank pneumatic rivet gun or air hammer. The 5/8" wide blade is engineered to apply controlled shear force across the rivet head or shank, allowing technicians to quickly “bust” or cut rivets during teardown or rework operations without damaging surrounding structure.

Unlike rivet setting tools, this is a demolition/removal attachment used in aircraft sheet metal repair, bridgework, shipbuilding, and heavy fabrication environments.

Key features include:

Pneumatic rivet removal chisel (rivet buster type tool)
.401 Parker taper shank compatibility (standard air hammer interface)
5/8" wide cutting blade for rivet shearing operations
Designed for removal of solid aircraft rivets (e.g., AN470 type)
Heat-treated alloy steel construction for impact resistance
Used with pneumatic rivet guns / air hammers (3X–5X class tools)
Suitable for aircraft structural disassembly and repair work
Reduces need for drilling out rivets in some applications
High vibration and impact durability for continuous use
Common in aerospace MRO, automotive, and heavy industrial maintenance
Available in various blade widths depending on rivet size and access requirements
