3M™ Regular Mandrel, 1/4 in Dia x 3 in L, For Roto Peen Flap Assemblies for Die Grinders

The 3M™ roto peen mandrel grips small flaps containing captive shot for peening of fine tolerance metals components. For use with flap assembly, we offer three sizes for internal diameters and flat surfaces. We engineered our 3M™ roto peen mandrel to deliver quick, efficient repair and maintenance to U.S. Army helicopters to components like rotors and rotor hubs in the field, our 3M™ roto peen mandrel and its associated flap assembly allowed peening action using a die grinder or disc sander. In the early 1970s, the 3M™ roto peen flap assembly (or TC 330) was qualified and written into military specifications. It soon spread to other aerospace applications.
