Parameter Description Unit
Selection
Selection of table value: e.g.
• M3; M10; etc. (ISO metric)
• W3/4"; etc. (Whitworth BSW)
• G3/4"; etc. (Whitworth BSP)
• 1" - 8 UNC; etc. (UNC)
P
- (selection
only possible for
table selection
"without")
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
second and third field.
• in mm/rev
• in inch/rev
The pitch is determined by the tool used.

αS
(only for G code)
Starting angle offset - (only for tapping without compensating chuck) Degrees

(only for G code)
Spindle speed - (only for tapping without compensating chuck) rev/min
Machining (not for
G code "with
compensating
chuck")
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
Without retraction distance after each machining step
V2 Retraction distance after each machining step – (only without compensating chuck,
chipbreaking and manual retraction)
Distance by which the drill is retracted for chipbreaking.
V2 = automatic: The tool is retracted by one revolution.

DT
(only for G code)
Dwell time at final drilling depth in seconds s
SR
(only for G code)
Spindle speed for retraction - (only for when a compensating chuck is not used) rev/min
