It carries the ANSI insert code CPMT3252 and ISO code CPMT09T308. The insert features an 80-degree diamond (rhombic) shape, a positive rake angle of 12 degrees, and an 11-degree relief angle. The KCP25B grade delivers moderate wear resistance and toughness, making it well suited for steel and cast iron applications. A honed cutting edge style and the MP chip breaker geometry support roughing and medium machining operations. Installation uses a screw-on holding method, and the insert provides two cutting edges per piece.\u003c\/p\u003e\u003cp\u003eThis insert is used in CNC and manual turning, facing, and boring operations on steel, cast iron, aluminum, and other non-ferrous materials. It is appropriate for both roughing and medium-duty passes in production and job-shop environments. The KCP25B grade is rated for steel (P) and aluminum and non-ferrous (N) workpiece material groups, covering moderate wear resistance through high toughness demands. Licensed machinists, CNC operators, and toolroom technicians typically specify this insert for external and internal turning applications where consistent chip control and edge life are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80-degree diamond (C-shape) insert geometry with positive rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eMultilayer CVD coating: TiCN, Al2O3, TiOCN for extended tool life on steel and cast iron\u003c\/li\u003e\n\u003cli\u003eMP chip breaker optimized for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003eScrew-on insert holding method for secure, repeatable indexing\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert maximize value per piece\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard CPMT-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for CPMT-style screw-on toolholders conforming to ANSI and ISO standards for CPMT3252 and CPMT09T308 insert seats.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed by a qualified machinist or CNC toolroom technician using the appropriate screw-on torx or hex key per the toolholder manufacturer specification. Ensure the machine spindle is fully stopped and the toolholder is removed from the turret or tool post before indexing or replacing the insert. Inspect the insert pocket and seating surface for chips or debris before seating a new insert. Follow the toolholder manufacturer torque guidelines for the clamping screw to avoid insert rocking or premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CPMT3252\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CPMT09T308\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CPMT\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiOCN (Multilayer CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MP (Roughing and Medium Machining)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 12 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.381 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.156 inches (5\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.031 inches (1\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.173 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.130 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Aluminum, Non-Ferrous\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: 0.007 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: 5413189\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747476734258,"sku":"5413189","price":211.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c34800531ad42033dae24a7d1fb2b4f1_93d7a4ff-703c-4db2-b013-1e8bb6b65114.jpg?v=1788881023","url":"https:\/\/voomisupply.com\/products\/kennametal-5413189-turning-insert-cpmt32-52mp-kcp25b","provider":"Voomi Supply","version":"1.0","type":"link"}
