The TP40 grade is engineered for high toughness in steel and stainless steel applications and provides moderate wear resistance in hardened materials. The 80-degree diamond (rhombic) insert shape, negative rake geometry, and MF3 chip breaker are optimized for finishing and light machining operations. With four usable cutting edges and a 0.5-inch inscribed circle, this insert delivers consistent performance in turning, facing, and boring applications. Licensed machinists and CNC operators working in job shop and production environments are the primary users of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel, stainless steel, and hardened materials in both light-duty and finishing passes. The MF3 chip breaker geometry controls chip formation during low-depth-of-cut finishing cuts. The TP40 grade aligns with ISO material grades P40, M35, and M40, making it a practical choice for production turning of carbon steel, alloy steel, and austenitic stainless steel on CNC lathes and turning centers. Insert holding methods include clamp, pin, and lever lock toolholders. Minimum order quantity is 10 inserts; each package contains one insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCNMG432-MF3 geometry with 80-degree diamond shape and negative rake for stable finishing cuts\u003c\/li\u003e\n  \u003cli\u003eTP40 carbide grade with multilayer CVD TiC\/TiCN\/TiN coating for high toughness in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eMF3 chip breaker optimized for finishing and light machining operations\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for extended tool life and lower cost per edge\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever lock CNMG toolholders\u003c\/li\u003e\n  \u003cli\u003eRated for turning, facing, and boring across ISO P, M, and H workpiece material groups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to fit standard CNMG toolholders that accept clamp, pin, or lever lock insert-holding methods.
