It carries the manufacturer grade designation 4425 and is coated via CVD process with an Al2O3, TiN, and TiCN multilayer coating applied over a solid carbide substrate. This combination targets steel and cast iron workpiece materials, delivering wear resistance and thermal stability at medium to high cutting speeds. With a 1\/4 inch inscribed circle, a 1\/32 inch corner radius, and a PF chip breaker geometry, the insert is suited for finishing and light-to-medium roughing passes where controlled chip evacuation is critical.\u003c\/p\u003e\u003cp\u003eThis insert belongs to the CoroTurn 107 series and is intended for use in compatible TCMT insert pockets on turning tool holders. It fits applications in general-purpose steel turning (ISO material group P) and cast iron turning (ISO material group K), including both residential and industrial machine shop environments. The neutral hand designation makes it interchangeable across standard TCMT-compatible holders. It is sold individually, with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD-applied multilayer coating: Al2O3, TiN, and TiCN for thermal and abrasion resistance\u003c\/li\u003e\n\u003cli\u003ePF chip breaker geometry for controlled chip formation in finishing and light roughing\u003c\/li\u003e\n\u003cli\u003e60-degree triangular insert shape provides 3 cutting edges per insert\u003c\/li\u003e\n\u003cli\u003e1\/32 inch (0.0313 inch) corner radius suited to fine-finish turning profiles\u003c\/li\u003e\n\u003cli\u003eRelief angle of 7 degrees with clearance code C and tolerance code M\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and screw insert-holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TCMT-compatible turning tool holders within the CoroTurn 107 series.

Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torque wrench and insert screw specified by the tool holder manufacturer — do not overtighten, as carbide inserts are brittle and can crack under excess clamping force. Inspect the insert pocket and clamping components for wear or debris before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer 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: Al2O3, TiN, TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (0.2500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inch\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\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 (P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TCMT 11 03 08-PF 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.44 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: 7861045\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51728544694578,"sku":"7861045","price":232.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35a5391bc75c919793cc740ef1de807a_bcd08ba1-5816-4649-834f-22c227f756f9.jpg?v=1788693062","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7861045-turning-insert-tcmt222-pf-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
