3M Roto Peen Flap Assemblies: Standard & Heavy Duty, TC 330

3M Roto Peen flap assemblies use tungsten carbide shot bonded to flexible flaps to peen metal surfaces, remove coatings, and blend repairs, commonly in aircraft and heavy equipment maintenance. We carry standard Roto Peen flaps in 9/16 x 1 in and 1 x 2 in sizes and a Heavy Duty 2 x 2-1/8 in flap. See 3M Mandrels & Adapters for mounting hardware.
