• For machining depth over 512", a single-ended insert is required (GIM, GIMF,GIMY,GIMT,GIMN) • CDX for grooving depth depends on part diameter Dmax
• For grooving a part with a diameter larger than CUTDIA, see next table
• For using TIP inserts, tool holder seat needs to be modified according to insert profile to ensure clearance
• For user guide, see pages 471-488
(1) In the case of inserts with CW<08", tool pocket should be ground to 012" thinner than the insert's grooving width
(2) For Star and multi-spindle machines
(3) Minimum cutting width
(4) Maximum cutting width
(5) Maximum parting diameter
(a) For optional key with limited tightening torque, see page 480
