Centring:
Position the ejector pin centrally on the centre punch.
Now the machine is in the correct drilling position. Please turn on magnet now.
Coolant supply:
The cutting oil is supplied through the ejector pin by the automatic internal
lubrication and is issued optimally to the cutting edges.
Ejecting:
In the final phase, the drill core is pushed from the borehole by the spring
pretensioned ejector pin.
