Pitch ...
• in MODULUS: MODULUS = Pitch/π
• in turns per inch: Used with pipe threads, for example.
When entered per inch, enter the integer number in front of the decimal point in the
first parameter field and the figures after the decimal point as a fraction in the sec-
ond and third field.
• in mm/rev
• in inch/rev
The pitch is determined by the tool used.

Machining (not in
the "with compen-
sating chuck"
mode)
The following machining operations can be selected:
• 1 cut
The thread is drilled in one cut without interruption.
• Chipbreaking
The drill is retracted by the retraction amount V2 for chipbreaking.
• Swarf removal
The drill is retracted from the workpiece for swarf removal.
D Maximum depth infeed - (only when used without compensating chuck, swarf removal
or chipbreaking)
mm
Retraction
Retraction distance - (for chipbreaking only)
• Manual
Retraction distance after each machining step (V2)
• Automatic
The tool is retracted by one revolution.
V2 Retraction distance after each machining step – (only without compensating chuck,
chipbreaking and manual retraction)
Distance by which the drill is retracted for chipbreaking.

only in the mode
"with compensat-

Dwell time in seconds:
• without compensating chuck
– 1 cut: Dwell time at final drilling depth
– Chip breaking: Dwell time at drilling depth
– Swarf removal: Dwell time at the drilling depth and after retraction
• with compensating chuck
– with encoder: Dwell time after drilling
– without encoder: Dwell time at final drilling depth
