The insert features an AlTiN (aluminum titanium nitride) PVD coating that supports moderate wear resistance and toughness across a range of workpiece materials. It carries an 80-degree diamond (rhombic) shape, a 3\/8 inch inscribed circle, a 1\/32 inch corner radius, and a positive rake angle of 15 degrees. The FP chip breaker is optimized for finishing cuts. Two cutting edges are available per insert. This insert is installed by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe CPMT3252FP KCU25 insert is suited for turning, facing, and boring operations. Its KCU25 grade characteristics make it applicable across steel, stainless steel, cast iron, aluminum and non-ferrous metals, and superalloys including titanium. The screw-on holding method and CPMT insert style are compatible with standard toolholders designed for the CPMT09T308 ISO designation and CPMT3252 ANSI designation. The positive side clearance and honed cutting edge style contribute to clean surface finishes in finishing-pass applications on a wide range of workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN PVD coating provides moderate wear resistance and toughness for steel, stainless steel, cast iron, aluminum, and superalloys\u003c\/li\u003e\n\u003cli\u003e80-degree diamond (rhombic) insert shape with positive rake angle for finishing cuts\u003c\/li\u003e\n\u003cli\u003eFP chip breaker geometry optimized for finishing operations\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method for secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert for extended tool life per unit\u003c\/li\u003e\n\u003cli\u003eApplicable for turning, facing, and boring multi-use applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CPMT-style screw-on toolholders conforming to ANSI designation CPMT3252 and ISO designation CPMT09T308.

The machine spindle must be fully stopped and all motion locked out before indexing or replacing inserts. Use the appropriate Torx or hex-key screw driver specified by the toolholder manufacturer to secure the clamping screw — do not overtighten. Inspect the toolholder pocket and seating surface for chips or damage before seating the new insert to ensure proper support and edge integrity.\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 Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU25\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: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: FP (Finishing)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 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 inch (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inches)\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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1268 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees\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\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\u003eHolding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Applications\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package (minimum order quantity: 5)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 3769428\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51746351808818,"sku":"3769428","price":183.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b41057d8ac3ba52d06e7b848273f2865.jpg?v=1788868792","url":"https:\/\/voomisupply.com\/products\/kennametal-3769428-cpmt3252fp-kcu25-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
