Working with Core Drills
Push the ejector pin (centring pin) through the core drill head.
Core drills with Weldon shank are tightened with clamping screws (DIN 913) on both clamping surfaces.
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!
