It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous and interrupted cuts. The insert has a 60-degree triangular shape with a neutral hand orientation, a 0.5-inch inscribed circle, a 0.0315-inch corner radius, and a maximum depth of cut of 0.2362 inches. Cutting edges are chamfered and honed for consistent edge integrity. Six usable cutting edges are available per insert, making this a cost-effective choice for production turning operations.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on cast iron at the K15 and K30 material grades. It fits standard TNMG-style toolholders using clamp or pin holding methods. Typical applications include CNC lathe and manual lathe work in job shop and production environments where cast iron components require reliable, repeatable surface finishes and dimensional control. The negative rake geometry at -15 degrees provides added edge strength when cutting abrasive or hard cast iron grades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear and thermal resistance\u003c\/li\u003e\n\u003cli\u003e60-degree triangle insert shape with neutral hand orientation\u003c\/li\u003e\n\u003cli\u003eSix cutting edges per insert for extended tool economy\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge style for consistent performance\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin holding methods\u003c\/li\u003e\n\u003cli\u003eSuitable for turning, facing, and boring on cast iron (K15, K30)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for standard TNMG 432 toolholder seats using clamp or pin clamping.
