(Note 1) The above table indicates the cutting conditions of 70% of the tool engagement. (Note 2) With low workspace clamping rigidity or long overhang of the tool, adjust cutting speed and feed to 70 or 80% of the recommended conditions above (Note 3) Surface finishing is determinated by speed/feed used. (Note 4) PH5… and PHS… can be used wet or dry. PH7… use only air.
