Parallel to the longitudinal axis, round files and two file faces are held without play but exchangeably in the head parts. The pairs of guide rods and the respective associated round files and the respective file faces are arranged in rotational symmetry with respect to the longitudinal axis. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
