Abstract:
An actuator for use in a directional steering assembly includes an ultrahard insert positioned on a working face. The ultrahard insert is positioned along at least a portion of the perimeter of the working face. The ultrahard insert has a coefficient of friction less than a material of the remainder of the working face.
