Gyration/reciprocating action switching mechanism for a power hand tool
 An improved vibration attenuator for reducing undesired vibrations generated by cutter bits being drawn across the faces of a rotating brake rotor. The attenuator has friction pads with engagement members that extend therefrom which are configured to cause force to exerted on the cutter bits in a direction parallel to the surface being machined and perpendicular to the direction of rotation of the rotor.
