Safety Notes
• Important note: On exit of the drill a disc as shown is ejected. With rotating components
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 application
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 manufacturer'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.

Coolant

The coolant is supplied centrally onto the cutting
edges through the basic element or the drill
head by means of ground coolant channels in
the central drill bit and on the drill head face.
Where coolant is applied centrally a cool-
ant medium is essential. Minimum coolant
pressure is 5 bar with coolant ring. When
cooling through spindle a higher pressure
should be chosen (10-20 bar).

This improves chip clearance.
