Carrying the 1125 manufacturer grade, this insert features a PVD-applied TiAlN and AlCr2O3 dual-layer coating engineered for high wear resistance when cutting stainless steel, steel, and special or super alloys. The 80-degree diamond (rhombic) insert shape provides a sturdy cutting edge geometry, while the MF chip breaker promotes clean chip evacuation during light finishing passes. With a 0.5-inch inscribed circle and a 1\/64-inch corner radius, this insert suits fine-tolerance turning work on close-tolerance part features. It is screw-held, neutral-hand, and carries a 7-degree relief angle with positive side clearance.\u003c\/p\u003e\n\u003cp\u003eThis insert is part of the CoroTurn 107 series and is intended for external and internal turning applications where surface finish and dimensional accuracy are priorities. It is suited for finishing cuts on stainless steel and steel workpieces in aerospace, energy, and general precision machining environments. Primary workpiece material codes M and S identify its application range: stainless steel with moderate-to-high wear resistance demands, and special or super alloys requiring balanced toughness. The MF chip breaker geometry is specifically optimized for finishing-depth cuts up to 12.50 mm, making it appropriate for final-pass work on tight-tolerance turned components in production or job-shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePVD-coated TiAlN and AlCr2O3 dual-layer finish for extended tool life on stainless steel and super alloys\u003c\/li\u003e\n  \u003cli\u003eMF chip breaker geometry optimized for finishing operations with maximum depth of cut of 12.50 mm (0.4921 inches)\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (CCMT) with positive side clearance for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003e1\/64-inch (0.40 mm) corner radius suitable for fine-tolerance features and shoulder work\u003c\/li\u003e\n  \u003cli\u003eScrew-held mounting method for secure seating and repeatable indexing in CoroTurn 107 compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert for efficient cost-per-edge value in high-volume finishing runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CoroTurn 107 series toolholders accepting CCMT431 inserts.

Before indexing or replacing the insert, ensure the machine spindle is fully stopped and the toolholder is secured in the turret or tool post. Use the appropriate Torx or hex key to seat the clamping screw without over-torquing the insert pocket. Inspect the insert pocket and seating surfaces for chips or debris before seating the new insert, as contamination in the pocket can affect insert stability and surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CCMT431\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCMT120404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 1125\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: TiAlN and AlCr2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80-Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF (Finishing)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5079 inches (12.90 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (0.40 mm)\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\u003eHole Diameter\u003c\/strong\u003e: 0.2165 inches (5.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.4921 inches (12.50 mm)\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel and Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Special and Super Alloys\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\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\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: 5724970\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51747468214578,"sku":"5724970","price":372.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fbf4f3f76010ea79f16113a3286c68c7_54aa8eff-44e6-46cc-9e44-df5dba7da5f6.jpg?v=1788880729","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5724970-turning-insert-ccmt431-mf-1125","provider":"Voomi Supply","version":"1.0","type":"link"}
