The insert is manufactured from solid carbide and features a multilayer MTCVD coating of TiCN and Al2O3, delivering a balance of moderate wear resistance and toughness suited to steel and cast iron applications. It carries an 80-degree diamond (rhombic) shape, a 3\/8-inch inscribed circle, a 1\/64-inch corner radius, and an insert length of 9.67 mm (0.3808 inches). The screw-on holding method and UF chip breaker geometry are optimized for finishing passes. Licensed machinists, CNC operators, and toolroom technicians are the primary users of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel and cast iron workpieces, as well as aluminum and non-ferrous materials where moderate wear resistance and toughness are required. The UF chip breaker geometry is engineered for finishing-depth cuts, with a maximum depth of cut of 1.25 mm (0.0492 inches). The positive rake angle of 5 degrees and positive side clearance support clean chip evacuation and reduced cutting forces, making this insert effective in light-to-moderate finishing applications on both P- and N-class workpiece materials per ISO classification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCP25 grade with multilayer CVD coating (TiCN plus Al2O3) for wear resistance and thermal stability\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with positive rake and positive side clearance for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eUF chip breaker optimized for finishing operations on steel, cast iron, aluminum, and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eScrew-on insert holding method for secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge for improved edge stability during finishing passes\u003c\/li\u003e\n\u003cli\u003e2 usable cutting edges per insert\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI (CCMT3251) and ISO (CCMT09T304) insert standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for screw-on CCMT-style toolholders conforming to ANSI insert code CCMT3251 and ISO insert code CCMT09T304.

Use the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturer's specified torque. Inspect the insert pocket and seating surfaces for chips or debris before installation to ensure proper seating and runout. Never attempt to index or replace inserts while the machine is running or the turret is energized.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CCMT3251\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCMT09T304\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: KCP25\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: UF (Finishing)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\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\/64 inch (0.0156 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\u003eRake Angle\u003c\/strong\u003e: 5 degrees (Positive)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 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 Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron (ISO P), Aluminum and Non-Ferrous (ISO N)\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\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\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: 3751703\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51729717166386,"sku":"3751703","price":213.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/627fa4be8d77a0b267dbc88098eb07e8.jpg?v=1788708330","url":"https:\/\/voomisupply.com\/products\/kennametal-3751703-ccmt3251uf-kcp25-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
