It features an 80-degree diamond (rhombic) shape, a 3\/8-inch inscribed circle, and a 3\/64-inch corner radius with chamfered and honed cutting edges. The MF chip breaker geometry is optimized for finishing and medium machining operations. With positive rake and positive side clearance, this insert delivers high wear resistance on steel and moderate wear resistance with toughness on aluminum and non-ferrous materials. Licensed machinists and CNC turning specialists install this insert in screw-on toolholders for precision metal removal.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel, cast iron, aluminum, and non-ferrous workpiece materials. Its KCP10 grade characteristics make it a strong performer in high wear-resistance applications on steel (P-class) and a capable option for aluminum and non-ferrous (N-class) work requiring a balance of toughness and wear resistance. The neutral hand orientation allows use in a wide range of screw-on toolholder configurations common in production and job-shop CNC turning centers. Maximum depth of cut is 0.0492 inches (1.25 mm), positioning this insert firmly in the finishing and light-to-medium machining range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCP10 grade with multilayer CVD TiCN and Al2O3 coating for extended tool life on steel and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eCCMT3253MF geometry: 80-degree diamond shape with MF chip breaker for finishing and medium machining\u003c\/li\u003e\n  \u003cli\u003ePositive rake and positive side clearance reduce cutting forces during light-to-medium passes\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style improves edge stability and surface finish\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert maximize usage before replacement\u003c\/li\u003e\n  \u003cli\u003eScrew-on holding method provides rigid, repeatable seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eNeutral hand insert fits a broad range of toolholder orientations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for screw-on style toolholders accepting CCMT3253 (ANSI) or CCMT09T312 (ISO) inserts.

Use the manufacturer-specified torque driver or wrench for the clamping screw to ensure proper seating without cracking the carbide substrate. Inspect the toolholder pocket for wear or debris before seating the insert, and confirm the cutting edge index before resuming operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CCMT3253\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCMT09T312\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: KCP10\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 (Multilayer CVD \/ MTCVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF (Finishing \/ Medium Machining)\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\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inch (0.0469 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\u003eInsert Width\u003c\/strong\u003e: 3\/8 inch (0.3750 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: 0.0492 inches (1.25 mm)\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: 0 degrees (Positive Rake)\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\u003eHolding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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: C3, C7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\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: 0.1 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: 3749444\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740521595186,"sku":"3749444","price":212.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/961c9a4cf3050805afdaa0b52868ccea.jpg?v=1788825641","url":"https:\/\/voomisupply.com\/products\/kennametal-3749444-ccmt3253mf-kcp10-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
