Bu CNMG 120404\/120408 R\/L-S carbide turning inserts<\/strong> combine an 80\u00b0 rhombic, negative-clearance insert body with a handed R or L cutting configuration. Specify them for external turning and facing of appropriate carbon and alloy steels with a compatible CNMG 1204 holder.<\/p>\n

Choose the 0.4 mm nose radius for a smaller corner and lighter feeds, or 0.8 mm for greater corner support where the workpiece profile and machine rigidity allow. Select the actual carbide grade, coating and S-geometry for the material, chip control, cutting load and surface-finish target.<\/p>\n

The R\/L-S suffix must be checked against the offered manufacturer’s drawing and the holder setup. The standard CNMG geometry identifies a turning insert; a dedicated grooving operation requires a tool and cutting geometry qualified for the groove width and depth.<\/p>\n<\/section>\n
