Working With Core Drills - ALFRA ROTABEST RB 35 SP Mode D'emploi

Working with Core Drills

Only use quick-change tool holder on the flat clamping face of the core drill.
 Push the centring and ejecting pin through the core drill head.
 Align the flat clamping face of the core drill on the marking in the swivel and turn the swivel of the quick-change
tool holder completely clockwise to open the tensioning block.
 Insert the core drill and turn the swivel back. Check the correct, firm fit of the core drill.
Risk of injury! Always wear gloves since the edges are sharp.
 Set the core drill on the work piece and start drilling until the whole cutting area is marked as a circular ring.
 The core drill should be cooled constantly during the drilling process. Optimum cooling is possible through our
coolant equipment using inner cooling.
 Do not switch the drive motor off during drilling, and after the drilling process pull the core drill back by turning
the star handle with the motor still running.
 Remove swarf and core after every drilling process.
Use swarf hook to remove the swarf. Do not touch with your bare hands. Risk of injury!
