(Note 1) Cutting conditions ae/Dc=70%. (Note 2) 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; Blind hole - When using long tool overhang with arbor type; Dc Flat bottom - When application has poor clamping rigidity or when using a low rigidity machine. Ødi = ØDH - ØDc
