(Note 4) It’s possible to occur vibrations in certain cases. Please reduce depth of cut and / or reduce cutting conditions in following cases:

- When using long shank; 195,3 - 4,2

- When using long tool overhang with arbor type;-198,44,3
- When application has poor clamping rigidity or when using a low rigidity machine.245,3-4,0

(Note 5) If chattering occurs, reduce ap and Vc by 30% and keep the same fz per tooth. 125 0,6 13,5 1289,1
