Carrying the IC807 manufacturer grade with a dual-layer TiN and TiAlN PVD coating, this insert delivers wear resistance and thermal stability across a broad range of workpiece materials. The 80-degree diamond (C) insert shape provides a strong cutting edge, while the NF chip breaker geometry promotes positive rake cutting action for efficient chip control. Machining technicians and CNC operators install this insert using clamp or pin holding methods on compatible toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is suited for universal application across steel, stainless steel, cast iron, non-ferrous, and high-temperature alloy workpieces, reflected in its ISO workpiece material codes H, K, M, P, and S. It is part of the Isoturn series and is also applicable for boring operations, making it a multi-use option in production and job-shop environments. The NF chip breaker targets finish to light roughing passes within the rated depth-of-cut range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC807 grade with TiN and TiAlN PVD dual coating for extended tool life across diverse materials\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CNMG style) with positive rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eNF chip breaker geometry engineered for controlled chip formation\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding compatibility for secure seating in standard CNMG toolholders\u003c\/li\u003e\n\u003cli\u003eMulti-use capability including turning and boring applications\u003c\/li\u003e\n\u003cli\u003eMeets ISO 13399 standards for tooling data representation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for standard CNMG431 toolholders.
