8.0 Speed adjustment dependent on the cutting speed
The values set out in the table are theoretical values and may be used to provide a rough guide for gear
changing. Since a whole range of other parameters also plays a major role in adjusting the speed, we can-
not offer any guarantee if the tool is damaged when using the values in the table. Drilling work for which the
speeds are outside the range of the core drill (values printed in italics), should only be completed with ex-
treme care and by trained personnel.
