coolant
The head features an internal coolant supply.
The use of the central coolant supply is mandatory. The cooling lubricant
helps to ensure optimum chip formation and chip removal.
The coolant pressure should not fall below the minimum of 5 bar. Increasing
the coolant pressure to 10-20 bar improves the machining process and is
therefore highly recommended where possible.

With the use of boring bars and the serrated body, the coolant is supplied
centrally through the body of the boring bar.
From a diameter of 63 upwards, the coolant-diverting packing piece must
be fitted. The packing piece prevents the coolant from escaping from the
center and diverts the coolant internally. Clamp the packing piece separately
using both securing screws
