This solid carbide insert carries a multilayer CVD coating of TiCN, Al2O3, and TiN, manufacturer grade 4415, which delivers wear resistance and thermal stability across a range of cutting conditions. The diamond-shaped insert features an 80-degree included angle, a 9.53 mm inscribed circle, and a 0.4 mm corner radius. The UM chip breaker geometry is engineered for controlled chip formation during medium to finish turning. Installation is performed by qualified machinists and CNC programmers on production and job-shop turning equipment.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for medium to finish turning of steel and cast iron workpieces, corresponding to ISO material groups P (steel) and K (cast iron). The CoroTurn 107 series targets applications requiring close tolerances and consistent surface finish on both external diameters and internal bores. The neutral hand orientation makes this insert compatible with standard right-hand and left-hand toolholders designed for CCMT pocket geometry. Typical applications include shaft turning, facing, and profiling passes in automotive, general engineering, and precision component manufacturing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and heat management\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade 4415 optimized for steel and cast iron cutting\u003c\/li\u003e\n  \u003cli\u003eUM chip breaker geometry for controlled chip formation in medium to finish turning\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (ISO shape code C) provides a strong cutting edge with versatile approach angles\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges per insert for extended tooling economy\u003c\/li\u003e\n  \u003cli\u003eClamp and screw holding method compatible with standard CoroTurn 107 toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders with CCMT pocket geometry within the SANDVIK COROMANT CoroTurn 107 series.
