The insert features an 80-degree diamond (rhombic) shape, a neutral hand orientation, and a honed cutting edge style optimized for finishing and light machining operations. With a 0.5 inch inscribed circle, a 0.03125 inch corner radius, and a negative rake angle of 10 degrees, this insert delivers consistent surface finish in high-precision turning applications. It is designed for use in KENLOC-style toolholders and is installed by machinists and CNC operators in production and job shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel, stainless steel, cast iron, superalloys, and titanium. Its KC5010 grade provides high to moderate wear resistance and toughness across ISO material groups P, M, K, N, and S. The LF chip breaker geometry targets finishing and light machining cuts with a maximum depth of cut of 0.0492 inch (1.25 mm). It is a multi-use insert appropriate for both light production runs and precision finishing passes on CNC lathes and turning centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5010 grade with TiAlN PVD coating for high wear resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003e80-degree diamond (rhombic) insert shape with negative rake for stable, secure cutting\u003c\/li\u003e\n\u003cli\u003eLF chip breaker optimized for finishing and light machining operations\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style reduces micro-chipping on demanding workpiece materials\u003c\/li\u003e\n\u003cli\u003e4 cutting edges per insert for extended tool life and lower cost per edge\u003c\/li\u003e\n\u003cli\u003eCompatible with both clamp and pin insert holding methods in KENLOC toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KENLOC-series toolholders accepting CNGG-style inserts.
