3M™ roto peen flap assembly, made with a flap and mandrel, was designed using captive shot flap technology. To create this unique and portable assembly, we adhered tungsten carbide shot to flexible flaps using high strength resin. Two flaps are bonded together with a special adhesive for easy placement in a flap mandrel.
