This solid carbide insert carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN under Sandvik grade 4415, engineered to balance wear resistance and heat dissipation during continuous and light interrupted cuts. The insert features an 80-degree diamond shape (shape code C), a 7-degree relief angle (clearance code C), and a neutral hand orientation. The UR chip breaker geometry promotes reliable chip control across a wide range of feeds and depths. ISO code is CCMT 09 T3 04-UR 4415. The insert holds a tolerance code of M and is held by clamp or screw.\u003c\/p\u003e\u003cp\u003eThis insert is part of the CoroTurn 107 series and is suited for finish to semi-finish turning of steel and cast iron workpieces on both light-duty and production turning setups. The 4415 grade targets ISO material groups P (steel) and K (cast iron), making it a general-purpose choice for shops running a variety of ferrous workpiece materials. It is commonly installed in toolholders sized for CCMT 3(2.5)1 inserts with a 3\/8-inch inscribed circle. Two cutting edges are available per insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, TiN for wear and thermal resistance\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with 7-degree relief angle for versatile turning geometry\u003c\/li\u003e\n\u003cli\u003e0.40 mm (0.0156 inch) corner radius for finish to semi-finish surface requirements\u003c\/li\u003e\n\u003cli\u003eUR chip breaker designed for controlled chip evacuation on steel and cast iron\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits standard CCMT toolholders\u003c\/li\u003e\n\u003cli\u003eTwo usable cutting edges per insert\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for CCMT 3(2.5)1 insert seats within the CoroTurn 107 toolholder system.

Seat the insert fully into the pocket before tightening the clamp or screw to the toolholder manufacturer specification. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert. Follow the toolholder manufacturer torque values and do not substitute insert grades or chip breaker geometries without verifying compatibility with the toolholder and programmed cutting parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CCMT 09 T3 04-UR 4415\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: 4415\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.40 mm (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches \/ 9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3.97 mm (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 4.40 mm (0.1732 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: UR\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 Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO Group P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO Group K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.43 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.54 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.74 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7859086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51737588433202,"sku":"7859086","price":239.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f8a89c263f7aa6f59567e1d70e60aca_cda2f7ef-5f47-4095-80c4-f33d81f97dc3.jpg?v=1788790957","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7859086-turning-insert-ccmt-4415","provider":"Voomi Supply","version":"1.0","type":"link"}
