It features a multilayer MTCVD coating system consisting of TiN, TiCN, and Al2O3, engineered to deliver moderate wear resistance combined with high toughness. The insert is 0.6496 inches (16.50 mm) long with a 3\/8-inch inscribed circle, a 1\/64-inch corner radius, and a 60-degree triangular shape. The MN chip breaker geometry targets roughing and medium machining operations. Licensed machinists and CNC turning professionals install this insert in KENLOC-compatible toolholders for steel and stainless steel turning, facing, and boring applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external and internal turning operations in both production and job-shop environments. The neutral hand orientation allows use in a range of setups. The KCP30 grade is rated for steel (P-class) applications requiring a balance of wear resistance and toughness, and for stainless steel (M-class) applications with moderate wear resistance and toughness demands. With six available cutting edges per insert, it provides good cost-per-edge value in medium to high-volume turning runs. The ANSI size code is 331 and the ISO equivalent designation is TNMG160404.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCP30 grade with multilayer MTCVD coating: TiN, TiCN, and Al2O3 for wear resistance and toughness\u003c\/li\u003e\n\u003cli\u003e60-degree triangular insert shape (T) with six cutting edges per insert\u003c\/li\u003e\n\u003cli\u003eMN chip breaker geometry designed for roughing and medium machining\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation supports turning, facing, and boring\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n\u003cli\u003eConforms to both ANSI and ISO standards (ANSI: TNMG331, ISO: TNMG160404)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENNAMETAL KENLOC series toolholders that accept TNMG-style inserts with a 0.15-inch hole diameter, negative rake, and N-clearance geometry.
