Note 1) This list of recommended cutting conditions is for flank wear of .012 inch in 30 min. cutting time. Note 2) More than 2 inch shank length should be clamped in the milling chuck. Note 3) Use peck feed when drilling. (.020 inch step is recommended) Note 4) When chattering occurs, reduce cutting speed to 70─ 80%. Note 5) When using round inserts, make sure that the flat portion of the flank surface is secure against the insert seat wall.
