Our 3M™ Roto Peen Flap Assembly effectively peens a variety of metals.
Use 3M™ Roto Peen Flap Assembly to effectively peen a variety of metals. Our flap assemblies are portable for added convenience. Tungsten carbide shot is bonded to the flaps, providing a cleaner peening method than loose shot ‘blasting’. These assemblies are especially effective for precision in service rework, manufacturing, repair of small areas, and peening holes. They impart a compressive residual stress that benefits the material by strengthening its durability. Available in three flap sizes for both small and large surface areas.
