The pitch is determined by the tool used.
αS Starting angle offset - (only for tapping without compensating chuck)

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)
Retraction Retraction distance - (for chipbreaking only)
Manual
