Function
The tool drills at the programmed spindle speed and
feedrate to the programmed final drilling depth.
With Boring 2, oriented spindle stop is activated with
the SPOS command once the drilling depth has
been reached. Then, the programmed retraction
positions are approached in rapid traverse and, from
there, the retraction plane.
