It features a solid carbide substrate with a CVD-applied multilayer coating consisting of Al2O3, TiCN, and TiN, which delivers thermal resistance and wear protection during continuous and interrupted cuts. The insert has a neutral hand orientation, a 0.375-inch inscribed circle, and a 0.0156-inch corner radius. It belongs to the T-Max P series and is intended for use by machinists and CNC turning specialists in production environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for steel turning applications, classified under ISO primary workpiece material code P. The LC chip breaker geometry is suited for light to medium cutting depths where controlled chip evacuation is critical. With four usable cutting edges per insert, it supports efficient tooling economics in high-volume turning cells on CNC lathes. The VNMG 16 04 04-LC 4415 ISO designation allows straightforward cross-referencing with toolholder systems and industry catalogs. Typical applications include finishing and semi-finishing passes on carbon steel, alloy steel, and similar ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: Al2O3, TiCN, and TiN for heat and abrasion resistance on steel\u003c\/li\u003e\n  \u003cli\u003eLC chip breaker geometry optimized for light to medium depth-of-cut on ferrous materials\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for extended tooling value\u003c\/li\u003e\n  \u003cli\u003e0.0156-inch corner radius for semi-finishing surface finish requirements\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard VNMG toolholders using clamp or screw holding\u003c\/li\u003e\n  \u003cli\u003eISO designation VNMG 16 04 04-LC 4415 for direct catalog cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in VNMG-style toolholders with clamp or screw holding methods.
