3M 7000046311 Roto Peen Mandrel Flap Assembly Tool

Product Description

The 3M 7000046311 is a Roto Peen Mandrel designed to drive Roto Peen Flap Assemblies in surface preparation and peening applications. The mandrel serves as the rotating drive component that accepts interchangeable flap assemblies, allowing the operator to mechanically peen, clean, or texture metal surfaces using a compatible rotary tool or drill. At 0.3 pounds, it is a lightweight drive accessory suited for controlled, repeatable surface work on ferrous and non-ferrous substrates. Tradespeople and fabricators working on weld prep, coating removal, or surface profiling will find this mandrel a core part of the Roto Peen system.

This mandrel is used with 3M Roto Peen Flap Assemblies sized 1 inch x 2 inch. Typical applications include surface preparation prior to coating or bonding, deburring, and weld seam cleanup on structural steel, pipe, and sheet metal. It is commonly used in industrial fabrication, shipbuilding, pipeline work, and maintenance environments where consistent surface profile is required before protective coatings are applied.
