(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; - When using long tool overhang with arbor type; - When application has poor clamping rigidity or when using a low rigidity machine. (Note 3) PH5… and PHS… can be used wet or dry. PH7… use only air. (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; - When using long tool overhang with arbor type; - When application has poor clamping rigidity or when using a low rigidity machine.
