It carries the ANSI code DCGT32.50.5MESI and ISO code DCGT11T302, with a 55-degree diamond (rhombic) shape and a positive rake geometry that reduces cutting forces on finish and semi-finish passes. The insert is PVD-coated with TiAlN and AlCrN layers under SUMITOMO proprietary Super ZX coating designation, grade AC530U. Key dimensions include a 3\/8 inch inscribed circle, a 0.4567 inch insert length, and a 0.0078 inch corner radius suited to fine surface finish requirements.\u003c\/p\u003e\u003cp\u003eThis insert is intended for light to medium machining applications. Grade AC530U is engineered for steel (P-class), stainless steel (M-class), and cast iron (K-class) workpiece materials, offering a range from high wear resistance to moderate toughness depending on the material group. It is appropriate for use in production turning environments where consistent chip control and coating durability are priorities. The MESI chip breaker geometry is optimized for light and medium depths of cut and is well-suited to finishing passes on stainless and alloy steels.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDCGT-style insert with 55-degree diamond shape and positive rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003ePVD TiAlN and AlCrN dual-layer coating (Super ZX) for thermal stability and edge retention\u003c\/li\u003e\n\u003cli\u003eGrade AC530U rated for steel (P), stainless steel (M), and cast iron (K) workpiece materials\u003c\/li\u003e\n\u003cli\u003eMESI chip breaker supports light and medium machining operations\u003c\/li\u003e\n\u003cli\u003e0.0078 inch corner radius for fine surface finish applications\u003c\/li\u003e\n\u003cli\u003eScrew-clamped insert holding method with positive side clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in DCGT-style screw-clamped turning toolholders with a 3\/8 inch inscribed circle seat.
