It features an 80-degree diamond (rhombic) shape, a negative rake geometry, and a chamfered and honed cutting edge style. Manufactured in the WAM30 grade and belonging to the Tiger-tec series, this insert is engineered for demanding metal-cutting operations. It delivers four usable cutting edges per insert, helping extend tool life between changeovers. The NR4 chip breaker geometry supports controlled chip evacuation across a range of feed rates and depths of cut.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring operations on CNC lathes and turning centers in both production shop and job shop environments. It is installed by machinists and tooling technicians working with indexable toolholders designed for CNMG-style inserts. The maximum depth of cut reaches 5.00 mm (0.197 inches), making it appropriate for medium-duty material removal passes. Its neutral hand orientation allows use in a wide variety of toolholder setups without handedness restrictions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eANSI code CNMG432 \/ ISO code CNMG120408  -  fits standard CNMG toolholders\u003c\/li\u003e\n  \u003cli\u003eWAM30 carbide grade in the Tiger-tec series for wear resistance in steel and cast iron applications\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with negative side clearance and negative rake for robust edge strength\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for extended service life and lower cost per edge\u003c\/li\u003e\n  \u003cli\u003eNR4 chip breaker supports turning, facing, and boring in a multi-use configuration\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method compatible with standard CNMG-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct fitment insert for indexable toolholders accepting CNMG432 (ANSI) or CNMG120408 (ISO) turning inserts with clamp and pin holding.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts.
