Manufactured to ISO and ANSI standards, it carries the CNGG4302FR designation with a TN60 cermet grade and a TiCN plus NbC coating classification noted as uncoated process. The insert features an 80-degree diamond shape, a negative rake angle of -15 degrees, and a sharp cutting edge style. With 4 usable cutting edges, a 0.500-inch inscribed circle, and a 0.004-inch corner radius, it is built for high-precision finishing and light to medium roughing passes. Machinists and CNC operators working in production environments are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external turning, boring, internal facing, chamfering, and facing operations. The F chip breaker geometry is optimized for steel and stainless steel workpieces, aligning with ISO material grades P01, P10, and P20 and secondary grade M. It performs best in applications demanding tight tolerances and consistent surface finish. The right-hand cutting orientation and clamp-plus-pin holding method make it compatible with standard CNGG-style toolholders used across general-purpose and production turning setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80-degree diamond insert shape with sharp cutting edge for precision turning\u003c\/li\u003e\n\u003cli\u003eTN60 cermet grade with TiCN and NbC coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eNegative rake at -15 degrees reduces cutting forces on light finishing passes\u003c\/li\u003e\n\u003cli\u003e4 cutting edges per insert for extended tool economy\u003c\/li\u003e\n\u003cli\u003eF chip breaker geometry controls chip flow during steel and stainless steel operations\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method provides secure seating in CNGG-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for CNGG4302FR-style toolholders accepting ISO CNGG inserts with a 0.500-inch inscribed circle and clamp-plus-pin retention.
