Built from solid carbide with a CVD-applied multilayer coating sequence of TiCN, Al2O3, and TiN, this insert delivers thermal resistance and wear protection across a range of cutting conditions. The insert carries a 55-degree diamond shape, a negative rake angle of -6 degrees, and a 0.0315-inch corner radius, making it suitable for medium-stock-removal passes where edge stability and surface finish both matter. It features 4 cutting edges per insert and a TM chip breaker geometry. Licensed machinists and CNC operators install this insert in standard DNMG-style toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for turning, facing, boring, back turning, and back boring applications. Primary workpiece materials are steel, stainless steel, and cast iron, corresponding to ISO material codes P, M, and K. Material grades P10 and P20 apply, positioning this insert for light-to-medium roughing and semi-finishing cuts in ferrous materials. It fits both clamped and pin-lock style DNMG toolholders. Residential and industrial machine shops, production turning cells, and job shops running steel and stainless components are the typical environments for this insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, TiN for thermal barrier and crater-wear resistance\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape with 4 usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eTM chip breaker geometry suited for medium-depth turning passes\u003c\/li\u003e\n  \u003cli\u003eNegative rake (-6 degrees) with sharp cutting edge style for edge strength\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert-holding methods\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ISO code DNMG 432 TM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for DNMG 432 TM toolholders that accept clamp or pin-lock holding methods.
