Drilling depth
● Shank (drilling depth in relation to the shank)
The drill is inserted into the workpiece until the drill shank reaches the value
programmed for Z1. The angle entered in the tool list is taken into account.
● Tip (drilling depth in relation to the tip)
The drill is inserted into the workpiece until the drill tip reaches the value
programmed for Z1.
Z1 Final drilling depth (abs) or final drilling depth in relation to Z0 (inc).
It is inserted into the workpiece until it reaches Z1.
Coolant on - M function to switch on the coolant.
