Handed insert shows Right-hand Available cutting diameter of KGM (for automatic lathe) / KGM-T (There is a limit to available grooving depth depending on the workpiece diameter.)

20 (CDX, ø40) 18 (CDX, ø130)

ø130 (Cutting dia.) ø40

If the workpiece diameter is large, the available grooving depth becomes smaller due to interference with the toolholder. e.g.) KGMR2525M-3T20+GMN3

KGM (for automatic lathe) possible cutting diameter and available grooving depth
