The insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous and light interrupted cuts. With an 80-degree diamond shape, a 0.5 inch inscribed circle, and a 1\/64 inch corner radius, this insert delivers consistent chip control through the MM chip breaker geometry. It is intended for machinists and tooling technicians working on production turning cells requiring reliable edge life and dimensional accuracy.\u003c\/p\u003e\n\u003cp\u003eThis insert is primarily recommended for turning stainless steel workpieces, corresponding to ISO material code M. The CoroTurn 107 series designation indicates suitability for screw-clamped toolholders configured for external turning, facing, and profiling operations in both light roughing and finishing passes. Its neutral hand configuration allows use on standard right-hand and certain left-hand setups depending on the toolholder selected. The MM chip breaker geometry supports medium-depth passes where chip evacuation and surface finish consistency are critical priorities in production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for elevated wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape provides a strong cutting edge with good approach angle flexibility\u003c\/li\u003e\n  \u003cli\u003eMM chip breaker geometry optimized for medium turning passes on stainless steel\u003c\/li\u003e\n  \u003cli\u003e1\/64 inch corner radius for a balance of edge strength and surface finish capability\u003c\/li\u003e\n  \u003cli\u003eScrew-clamped insert holding method for positive, repeatable seating in CoroTurn 107 toolholders\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert to maximize cost-per-edge value in production runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CoroTurn 107 series screw-clamped toolholders accepting CCMT insert style with clearance code C, tolerance code M, and a 5.50 mm hole diameter.

Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturer specification — do not overtighten, as this can fracture the insert or damage the pocket seating surface. Inspect the toolholder pocket for chips or debris before seating the new insert, and verify edge orientation matches the intended cutting direction before resuming operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CCMT 12 04 04-MM 2025\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 2025\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond, 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MM\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: 0.4920 inches (12.50 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: 0.0156 inches (0.40 mm)\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\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Code M)\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\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: 5724953\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51744798966066,"sku":"5724953","price":333.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/beff3108e9d97a52c1a229da39fbbae1_242f982e-ce3d-4835-a46f-25c8d69017ef.jpg?v=1788860678","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5724953-turning-insert-ccmt431-mm-2025","provider":"Voomi Supply","version":"1.0","type":"link"}
