Caution: The given cutting data are guide values. In any case, they have to be adapted to the actual working conditions.
For cutting speeds above 400 m/min, we recommend to use the balanceable fine boring heads, e.g. 309.601 or 310.605A and to balance the complete tool assembly.
The weight of long tools can be substantially reduced by using CKN lightweight components with equal cutting performance.
