Values shown in the table are based on two conditions:
1. According to the instructions of the collet manufacturer, the outer side of the collet must be
at least 1 mm thick.
2. Sprockets are on their intermediate position (edges in contact with the bar) forming thus a
channel the diameter of which is approximately 1 mm smaller than the guide channel
diameter resulting from sprocket standard rotation.
