Product Description

The 3M 7000045884 is a roto peen mandrel designed to drive 3M Roto Peen Flap Assemblies in surface preparation applications. The mandrel serves as the rotating attachment that holds and spins flap assemblies against a work surface, producing a controlled peening action used to clean, descale, or prepare metal surfaces. It is a component-level tool accessory sold individually and is typically used by pipefitters, ironworkers, maintenance technicians, and industrial tradespeople performing surface prep before coating, welding, or inspection work.

This mandrel is intended for use with 3M Roto Peen Flap Assemblies sized 9/16 inches by 1 inch. It is suited for metal surface preparation tasks in both field and shop environments, including removal of mill scale, rust, and corrosion on pipe, structural steel, and fabricated components. Typical installations involve attachment to a pneumatic or electric rotary tool capable of accepting the mandrel shank.
