\par \pard\cf0\b0\f2 The tool drills at the programmed spindle speed and feedrate to the entered final drilling depth.
\par Deep hole drilling is performed with a depth infeed of a maximum definable depth executed several times, increasing gradually until the final drilling depth is reached.
\par The drill can either be retracted to the reference plane + safety clearance after every infeed depth for swarf removal or retracted in each case by 1 mm for chip breaking.\f0\fs16
