Centering bracket:
Assembly of the centering bracket is carried out by screwing it onto the rotational axis of
the universal swivel holder. To do this, the screw plug which protects the thread against
dirt must be removed. The centering bracket has a movable contacting aid. With the
assistance of the flattened side the tool can be aligned and fixed. With the assistance of
the point an adjusted radius can be optically monitored.

The front end of the tool is to be fixed to the contacting aid of the centering bracket. After

fine stopper is to be positioned in the way that re-adjustment can be carried out about the
value of the radius.
