Working With Core Drills - Alfra Rotabest Rb 35 Sp Manuel D'utilisation

Working with core drills

Only use quick-change tool holder on the flat clamping face of the core drill.
• Push the ejector pin (centring 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 workpiece 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 with the
motor still running.
• Remove swarf and core after every drilling process.
Use a swarf key to remove the swarf. Do not touch with your bare hands. Risk of injury!
