■ Guide for Drilling [Depth of Drilling] ・Ref. to Pd value of Toolholder Dimension Table on Page M180, M181 　(Pd Shows the maximum plunge depth.) [When Traversing after Drilling] (1) Reduce the table feed by 50% until the center core part (do not forget to grind) is completely cut off. (The internal cutting edge's radial rake angle is large in the L negative direction) (2) The min. cutting length “L” for flat bottom surface is as below Insert Description L (mm) RDMT08T2M0-H φD-7 RPMT10T3M0 φD-9 RPMT1204M0 Center Core φD RPMT1204M0-H φD-11 RPMT1606M0-H φD-15 ■ Guide for Ramping (Slant Milling) The transfer length “L” at the maximum slant angle α in the ramping operation depends on the ap.
