It features an 80-degree diamond (rhombic) insert shape, a positive rake angle of 5 degrees, and an 11-degree relief angle with positive side clearance. The inscribed circle measures 3\/8 inches (0.375 inches), insert length is 9.67 mm (0.3808 inches), and thickness is 5\/32 inches (0.1563 inches). The LF chip breaker is optimized for finishing and light machining operations. Installation and use are performed by machinists and CNC turning specialists working on steel, cast iron, aluminum, and other non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for turning, facing, and boring applications in both steel and non-ferrous workpiece materials. The KCP25 grade delivers moderate wear resistance and toughness, making it well suited to steel (ISO P) and aluminum and non-ferrous (ISO N) material groups. It mounts via screw-on holding method and provides two cutting edges per insert, reducing per-edge tooling cost. Typical applications include finish turning passes and light continuous cuts where dimensional accuracy and surface finish are priorities. Operators running CNC lathes or manual turning centers in job shop and production environments will find this insert appropriate for moderate-speed, low-feed finishing work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCP25 grade with multilayer CVD TiCN and Al2O3 coating for wear resistance on steel and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (rhombic) insert shape with positive rake and positive side clearance for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eLF chip breaker geometry optimized for finishing and light machining operations\u003c\/li\u003e\n  \u003cli\u003eScrew-on insert holding method provides secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert; honed cutting edge style for smooth surface finish\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 1.25 mm (0.0492 inches) for light finishing passes\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO insert standards (ANSI: CPMT3252, ISO: CPMT09T308)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw-on turning insert conforming to ANSI code CPMT3252 and ISO code CPMT09T308, suitable for use in any compatible CPMT-style screw-on toolholder accepting an 80-degree diamond insert with a 3\/8-inch inscribed circle.

Ensure the machine spindle is fully stopped and the turret or tool post is locked out before indexing or replacing inserts. Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturer's specified procedure; do not overtighten. Inspect the insert pocket and seating surface for chips or debris before mounting to maintain accurate insert position and prevent 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: 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\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP25\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD (CVD Multilayer)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF (Finishing \/ Light Machining)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 9.67 mm (0.3808 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inches (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0313 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\u003eRake Angle\u003c\/strong\u003e: 5 degrees (Positive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\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 Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Aluminum and 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\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package (MOQ: 5)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 3751580\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740373614898,"sku":"3751580","price":183.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80b34919da273e2123bb354825bf92da.jpg?v=1788824596","url":"https:\/\/voomisupply.com\/products\/kennametal-3751580-turning-insert-cpmt3252lf-kcp25-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
