It features a 55-degree diamond (rhombic) shape with a positive rake angle of 12 degrees and a 7-degree relief angle, making it well-suited for moderate material removal rates where both wear resistance and toughness are required. The insert measures 11.63 mm (0.9156 inches) in length with a 3\/8-inch inscribed circle and a 1\/32-inch corner radius. It carries two cutting edges and uses a screw-on holding method. Licensed machinists and CNC turning specialists install this insert in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe MP chip breaker geometry targets roughing and medium machining operations. Primary workpiece materials are steel and cast iron (ISO material code P), with additional suitability for aluminum and non-ferrous materials (ISO code N). Multi-use applications include turning, facing, boring, back turning, and back boring. The insert conforms to both ANSI and ISO standards, with ANSI insert code DCMT3252 and ISO insert code DCMT11T308, allowing straightforward toolholder cross-referencing across both systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMTCVD multilayer TiCN and Al2O3 coating for wear resistance in steel and cast iron applications\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond shape with positive rake (12 degrees) and positive side clearance for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eMP chip breaker optimized for roughing and medium machining passes\u003c\/li\u003e\n  \u003cli\u003eKCP25 grade delivers moderate wear resistance and toughness across steel (P) and non-ferrous (N) workpiece categories\u003c\/li\u003e\n  \u003cli\u003eTwo usable cutting edges per insert; screw-on mounting for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO insert standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for screw-on style DCMT toolholders conforming to ANSI size code 3252 and ISO size code 11T308.

Power down and lock out the machine spindle before changing inserts. Use the correct Torx or hex key specified by the toolholder manufacturer to seat the clamping screw  -  do not overtighten, as this can fracture the carbide substrate. Inspect the insert pocket and seating surface for chips or debris before seating a new insert to ensure accurate tool-nose positioning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DCMT3252\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DCMT11T308\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN and Al2O3 (MTCVD multilayer CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 11.63 mm (0.9156 inches)\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 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: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\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\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\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: 3639877\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743945687346,"sku":"3639877","price":169.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c11b0ecdbe9e345eb1e465c8556593c.jpg?v=1788851730","url":"https:\/\/voomisupply.com\/products\/kennametal-3639877-dcmt3252mp-kcp25-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
