Built from CVD-coated carbide in a 55-degree diamond (rhombic) shape, this insert carries manufacturer grade ACM20P and is engineered for high wear-resistance to moderate wear-resistance and toughness applications. It features a neutral hand orientation, negative side clearance, and an IPK+ chip breaker geometry. With 4 cutting edges per insert and a corner radius of 0.40 mm (0.0157 inches), it delivers consistent performance across a range of turning operations. Licensed machinists and CNC operators install this insert in compatible toolholders using clamp, lever lock, pin, or screw holding methods.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning steel (P) and stainless steel (M) workpiece materials, covering applications from high wear-resistance to moderate toughness demands. It fits into DNMG-style toolholders and is commonly used in production turning, facing, and profiling operations in both job shop and high-volume manufacturing environments. The CI series designation and ANSI size code 431 (ISO 150404) confirm compatibility with standard DNMG toolholder pockets used across a wide range of machine tool setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD coating with ACM20P grade for extended tool life on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eIPK+ chip breaker geometry for effective chip control during turning operations\u003c\/li\u003e\n\u003cli\u003e4 indexable cutting edges per insert for maximum value per piece\u003c\/li\u003e\n\u003cli\u003e55-degree diamond (D) insert shape with negative side clearance for versatile turning profiles\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard DNMG toolholder configurations\u003c\/li\u003e\n\u003cli\u003eMultiple holding method compatibility: clamp, lever lock, pin, and screw\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for DNMG431 (ISO DNMG150404) toolholder pockets.
