Cataloged under the CoroTurn 107 series, this insert carries the ISO designation CCMT 09 T3 04-UR 4425 and features an 80-degree diamond shape with a neutral hand orientation. The CVD-applied multilayer coating stack — TiCN, Al2O3, and TiN — is engineered for heat resistance and wear life during steel and cast iron machining. The 4425 grade is a cemented carbide grade suited to continuous and light-interrupted cuts at moderate to high cutting speeds. A 0.40 mm corner radius balances edge strength and surface finish. Two cutting edges per insert are available.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in positive-rake CoroTurn 107 toolholders that accept CCMT-style inserts with a clamp and screw holding method. Primary workpiece material is steel (ISO material group P), with cast iron (ISO material group K) listed as a secondary application. Typical use cases include shaft turning, facing, and contour turning in production environments. The UR chip breaker geometry is suited to universal roughing and medium finishing passes. This insert is sold individually; minimum order quantity is 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for thermal resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (Shape Code C) for versatile turning and light profiling\u003c\/li\u003e\n  \u003cli\u003e4425 carbide grade optimized for steel and cast iron at moderate to high cutting speeds\u003c\/li\u003e\n  \u003cli\u003eUR chip breaker geometry for universal roughing and medium finishing applications\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with both right- and left-hand toolholder setups\u003c\/li\u003e\n  \u003cli\u003eClamp and screw holding method for secure, repeatable insert positioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CoroTurn 107 series toolholders accepting CCMT-style inserts with clamp and screw holding.

Power down and lock out the machine spindle before changing inserts. Use the correct Torx or hex key for the clamping screw as specified by the toolholder manufacturer — do not overtighten, as insert cracking or seat damage can result. Inspect the insert pocket and shim seat for wear or debris before seating a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CCMT 09 T3 04-UR 4425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Catalog Number\u003c\/strong\u003e: CCMT 3(2.5)1-UR 4425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degree included angle, Shape Code C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCarbide Grade\u003c\/strong\u003e: 4425\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, Al2O3, TiN (CVD process)\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 inches (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\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\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Clamp and Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO Code K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches (L) x 1.54 inches (W) x 0.43 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7860876\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51755638915378,"sku":"7860876","price":239.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f8a89c263f7aa6f59567e1d70e60aca_0909962f-d0d8-4b81-80eb-e1ba09e6bd8c.jpg?v=1788957428","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7860876-turning-insert-ccmt32-51-ur","provider":"Voomi Supply","version":"1.0","type":"link"}
