This insert features a multilayer CVD coating system — TiCN, Al2O3, and TiOCN applied via MTCVD process — delivering a balance of high toughness for steel and moderate wear resistance for stainless steel. The 55-degree diamond (D) shape with a negative rake angle and neutral hand orientation suits a wide range of turning, facing, boring, back turning, and back boring applications. It provides four usable cutting edges per insert, making it an efficient replacement consumable for production environments.\u003c\/p\u003e\n\u003cp\u003eThe 5591902 is sized at 0.5 inches inscribed circle with an insert length of 1.2208 inches and a corner radius of 0.0156 inches (1\/64 inch). The MP chip breaker geometry is optimized for roughing and medium machining operations. Primary workpiece materials include steel (ISO P), stainless steel (ISO M), and superalloys and titanium. It is held by clamp or pin methods, consistent with standard KENLOC tooling systems. This insert suits both high-production shops and job shops running mixed material programs where a single insert grade must cover multiple part types.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMultilayer CVD coating — TiCN, Al2O3, TiOCN — via MTCVD process for thermal resistance and edge toughness\u003c\/li\u003e\n  \u003cli\u003eMP chip breaker geometry rated for roughing and medium machining operations\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape with four usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eNegative rake, negative side clearance (N relief) geometry for stable interrupted and continuous cuts\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert-holding methods in KENLOC toolholders\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ANSI code DNMG431, ISO code DNMG150404\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-grade replacement insert for KENLOC series toolholders accepting DNMG-style inserts.

Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the pocket and secure with the appropriate clamp or pin per the toolholder manufacturer specification before resuming cuts. Inspect the insert pocket and seating surface for chips or debris before installing a new edge to avoid premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNMG431\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNMG150404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: DNMG431MP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG150404MP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCM25B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55-Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing;
