(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.
