It features a multilayer MTCVD coating of TiCN and Al2O3, engineered for high wear resistance on steel and moderate wear resistance with toughness on aluminum and non-ferrous materials. The insert carries an 80-degree diamond (rhombic) shape, a neutral hand orientation, a negative rake and negative side clearance, and a wiper finishing chip breaker (FW). With 4 usable cutting edges and an inscribed circle of 0.5 inches, it suits precise finishing passes where tight surface finish tolerances are required. Installation is performed by licensed or experienced machinists on CNC and manual lathes.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for turning, facing, and boring operations in production and job-shop environments. Its primary workpiece materials are steel and cast iron, with secondary applicability to aluminum and non-ferrous alloys. The wiper edge geometry enables faster feed rates while maintaining fine surface finishes, making it well suited to high-volume finishing cycles on CNC turning centers. The KENLOC holding system accepts both clamp and pin insert-holding methods, providing secure seating under interrupted and continuous cuts alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCNMG431FW geometry with 80-degree diamond shape and wiper finishing chip breaker for superior surface finish at elevated feed rates\u003c\/li\u003e\n  \u003cli\u003eKCP05 grade with multilayer MTCVD TiCN and Al2O3 CVD coating for high wear resistance on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e4 cutting edges with neutral hand and honed cutting edge style for consistent, repeatable performance\u003c\/li\u003e\n  \u003cli\u003eNegative rake and negative side clearance (clearance code N, tolerance code M) for robust edge stability\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert-holding methods; fits KENLOC toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI (CNMG431) and ISO (CNMG120404) insert standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC-series toolholders accepting CNMG431 (ANSI) or CNMG120404 (ISO) inserts with clamp or pin holding.

Use the appropriate KENLOC clamp or pin-retention hardware specified for the toolholder; ensure the insert seat and pocket are clean and free of debris before seating the insert. Torque clamping screws only to the toolholder manufacturer's specification. Verify runout and edge condition before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG431\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG431FW\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP05\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80-Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: FW (Wiper - Finishing)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN and Al2O3 (Multilayer MTCVD CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 12.90 mm (0.5077 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3748377\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739980071218,"sku":"3748377","price":184.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f918503e582f7fa5520ea8fe710d136.jpg?v=1788821012","url":"https:\/\/voomisupply.com\/products\/kennametal-3748377-turning-insert-cnmg431fw-kcp05-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
