The cooling lubricant is supplied centrally through the basic body over the
contact surface of the core bit directly to the cutting edges and the centring
spade. It is essential for central coolant supply to be used. The coolant helps
produce the best possible chip formation and chip removal. Coolant pressure
should not be less than the minimum 5 bar. Increasing the coolant pressure
to 10–20 bar improves the boring process.
Safety Notes
• Important note: On exit of the drill a disc as shown is ejected. With rotating com-
ponents this can cause accidents. Please arrange suitable guarding.
• The application data specified in the "Recommended application areas" depends
on the ambient and application conditions (e.g. the machine, ambient temperature, lubricant/
cooling lubricant used and desired machining results): these presuppose appropriate applica-
tion conditions, use and compliance with the spindle speed limits specified for the tools.
• To prevent damage to machine and tool, we recommend that the drive power be calculated
in advance. The drive power which is actually available will be found in the machine manu-
facturer's spindle speed/performance diagram.
• Safety equipment should be provided to protect personnel from flying chips.
• To ensure the best possible tool life, the insert should be changed promptly.
