The insert features a multilayer CVD coating stack of TiCN, Al2O3, and TiOCN applied via MTCVD process, delivering a balance of wear resistance and toughness suited to steel and cast iron workpieces. The 80-degree diamond (rhombic) shape provides a strong cutting geometry with a negative rake and negative side clearance. With four usable cutting edges and a wiper edge geometry in the MW chip breaker, the 5387663 is built for medium-machining operations including turning, facing, and boring.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in steel (ISO P) and cast iron (ISO N) applications where moderate wear resistance and toughness are priorities. The MW chip breaker is optimized for medium depth-of-cut and feed-rate ranges, making it a practical choice for semi-finishing and moderate roughing passes on production turning equipment. It is seated using clamp-and-pin holding methods in compatible KENLOC toolholders. Machinists and CNC operators in production shops, job shops, and aerospace or general manufacturing environments will find this insert appropriate for high-volume turning of ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCP25B grade with multilayer CVD coating (TiCN, Al2O3, TiOCN) for wear resistance and toughness on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eMW wiper chip breaker geometry optimized for medium machining — turning, facing, and boring\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with negative rake and negative side clearance for rigid, stable cutting\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for extended tool life per unit\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style reduces chipping and improves edge consistency\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin holding methods in KENLOC toolholder series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC-series toolholders accepting CNMG432 (ISO CNMG120408) inserts with clamp and pin holding.

Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully into the pocket before tightening the clamp to ensure proper edge engagement and avoid insert rocking. Inspect the pocket and locating pin for wear or debris before each insert change to maintain positioning accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code (Full)\u003c\/strong\u003e: CNMG120408MW\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP25B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiOCN (Multilayer CVD, MTCVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MW (Wiper - Medium Machining)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5077 inches\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 Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 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: 0.200 inches (5.08 mm)\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: 5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C6, C7\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: 0.02 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: 5387663\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749271339314,"sku":"5387663","price":183.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40156eb26169370fa3f4cb7f2ca16cf2_d1454125-8345-4c37-b5c2-006fd5606104.jpg?v=1788903859","url":"https:\/\/voomisupply.com\/products\/kennametal-5387663-turning-insert-cnmg432mw-kcp25b","provider":"Voomi Supply","version":"1.0","type":"link"}
