with ALFRA ROTABEST cutters does not require much expenditure of force. Set
the cutter and spot-drill, until the entire cut edge is formed as a circle.
During the drilling process, the cutter should be cooled permanently. Optimal
Cooling is possible by internal cooling with our coolant unit.
During the drilling process, do not stop the motor. After the process, cutter draw
back with running motor.
Remove chips and core after each drilling. Remove chips with Chip-Remover – do
not touch with bare hands –
