Operating tips

First, place annular cutter with ejector pin on a marked centre or marking. Drilling 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 (b).
During the drilling process, do not Stop the motor. After the process, cutter draws back
with running motor.
Remove chips and core after each drilling. Remove chips with Chip-Remover – do not
touch with bare hands – DANGER OF INJURY!
