line is available for partial profile and can produce internal threads in minimum bore diameter
of 4.0 mm (0.157 inches). The inserts in this line are peripheral ground with a pressed
deflector for chip evacuation. The clamping concept of the insert into the holder is based on THREAD TURNING
self-clamping (without clamping screw).
