It carries the IC8150 manufacturer grade and features a multilayer CVD coating sequence of TiCN, Al2O3, TiCN, and TiN, which delivers high wear resistance across a range of cutting conditions. The insert measures 12.4 mm in length with an inscribed circle of 0.2815 inches and a corner radius of 0.0157 inches. Its 35-degree diamond (rhombic) shape and negative side clearance make it well suited for finishing passes where tight tolerances and surface finish consistency are required. Machinists and CNC operators in production and job-shop environments install and index this insert type.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for finishing applications on steel (ISO P), cast iron (ISO K), and hardened materials (ISO H). The NF chip breaker geometry is optimized for light, finishing-depth cuts with a maximum depth of cut of 2.00 mm (0.0787 inches). It is used on external turning, facing, and profiling operations where workpiece surface integrity and dimensional accuracy are the primary goals. The IC8150 grade offers high wear resistance for steel and cast iron, transitioning toward moderate toughness where conditions require it, making it a versatile finishing-grade choice across common production materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN \/ Al2O3 \/ TiCN \/ TiN for extended tool life in finishing cuts\u003c\/li\u003e\n  \u003cli\u003eIC8150 grade rated for high wear resistance on steel (P), cast iron (K), and hardened materials (H)\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape (V) with negative side clearance for stable clamping\u003c\/li\u003e\n  \u003cli\u003eNF chip breaker geometry optimized for finishing operations with light depths of cut\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tooling data standards for easy tool management integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders accepting VNMG-style inserts with a 2.5-1 ANSI size code and ISO size code 12T304.
