Manufactured under the KCP25B grade, it delivers moderate wear resistance combined with toughness, making it suited for steel and cast iron machining across roughing and medium machining operations. The insert features an 80-degree diamond rhombic shape, a neutral hand orientation, and four usable cutting edges with chamfered and honed cutting edge geometry. It falls within the KENLOC series and is held in place via clamp or pin methods. Licensed machinists and CNC operators install this insert on turning centers and lathes.\u003c\/p\u003e\u003cp\u003eThe KENNAMETAL 5989963 is designed for turning, facing, and boring operations on steel and cast iron workpieces. It is rated for primary workpiece material codes P and N, covering general steels and non-ferrous materials with moderate wear resistance and toughness to high toughness characteristics. The MG chip breaker geometry supports both roughing and medium machining passes, allowing versatile use across roughing and finishing stages without changing insert style. This makes it a practical multi-use insert for production turning environments where minimizing tool changes is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer MTCVD CVD coating: TiCN plus Al2O3 plus TiOCN for wear resistance and toughness balance\u003c\/li\u003e\n\u003cli\u003eKCP25B grade suited for steel and cast iron at moderate wear-resistance and toughness levels\u003c\/li\u003e\n\u003cli\u003e80-degree diamond rhombic insert shape with negative rake and negative side clearance\u003c\/li\u003e\n\u003cli\u003eMG chip breaker supports roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003eFour cutting edges with chamfered and honed edge preparation\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards: CNMG433 and CNMG120412\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement turning insert for toolholders and systems within the KENLOC series that accept CNMG433 or CNMG120412 geometry inserts with clamp or pin holding methods.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully in the pocket and secure using the appropriate clamp or pin torque driver per the toolholder manufacturer guidelines. Inspect the insert pocket and seating surfaces for chips or debris before installation to ensure proper support and runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG433\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120412\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\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\u003eManufacturer Grade\u003c\/strong\u003e: KCP25B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Layers\u003c\/strong\u003e: TiCN, Al2O3, TiOCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing, Medium Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\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\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5077 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: 0.0469 inches (3\/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: 0.1691 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\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered, Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, 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\u003eSeries\u003c\/strong\u003e: KENLOC\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: 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5989963\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742140399922,"sku":"5989963","price":45.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6ff101de7e798713d326369334a3dcd.jpg?v=1788835512","url":"https:\/\/voomisupply.com\/products\/kennametal-5989963-cnmg433mg-kcp25b-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
