3M 7000046310 Roto Peen Mandrel Flap Assembly

Product Description

The 3M 7000046310 is a replacement mandrel designed for use with Roto Peen Flap Assemblies. The mandrel serves as the drive shaft that holds and spins the flap assembly during surface preparation work. It mounts to a rotary tool or die grinder and transmits rotational force to the carbide-tipped flap segments. Weighing 0.2 pounds, it is a compact, single-piece component sized to accept 9/16 inch by 1-1/4 inch flap assemblies. Surface prep technicians, metalworkers, and maintenance trades use this mandrel when descaling, deburring, or preparing metal surfaces for coating or welding.

This mandrel is suited for applications where controlled surface profiling is required on metal substrates. Typical use cases include rust and scale removal, weld spatter cleanup, and surface texturing ahead of protective coating application. It is sold individually and is intended to be paired with compatible 3M Roto Peen Flap Assemblies measuring 9/16 inch by 1-1/4 inch. Industrial maintenance, fabrication shops, and coating prep crews are the primary users of this tooling component.
