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 240 m/min, we recommend to balance the complete and pre-set tool assembly or to use a balanceable fine boring head on a fine balanced tool shank, e.g. 309.301 and 324.331F.
