Built from solid carbide with a CVD-applied TiCN, Al2O3, and TiN multilayer coating, this insert is engineered for durability and thermal resistance during continuous and interrupted cuts. It features an 80-degree diamond shape (C insert shape code), a 0.5000-inch inscribed circle, and a 0.0313-inch (1\/32 inch) corner radius. The MM chip breaker geometry is optimized for controlled chip evacuation. The insert carries a neutral hand orientation and offers four usable cutting edges per insert, maximizing cost efficiency per edge for production shops.\u003c\/p\u003e\u003cp\u003eThis insert is part of the SANDVIK COROMANT T-Max P series, which targets medium to finishing turning operations. Its primary workpiece material classification is stainless steel (ISO code M), making it well suited for shops machining austenitic, duplex, or martensitic stainless grades. Typical applications include OD turning, facing, and profiling passes on a CNC lathe where controlled chip formation and edge stability are critical. The ISO designation for this insert is CNMG 12 04 08-MM 2025. Sold individually per package, with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for thermal barrier and wear resistance\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with neutral hand orientation\u003c\/li\u003e\n\u003cli\u003eMM chip breaker geometry for stainless steel chip control\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert (CNMG style, clamp and pin holding method)\u003c\/li\u003e\n\u003cli\u003e0.0313-inch corner radius for moderate edge strength and surface finish\u003c\/li\u003e\n\u003cli\u003eManufacturer grade 2025, part of the T-Max P series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in toolholders that accept CNMG 432 inserts with clamp and pin holding method.

Power down and lock out the machine spindle before seating or indexing the insert. Use the correct torque wrench and SANDVIK-specified clamping hardware to secure the insert — do not substitute generic clamps. Inspect the insert pocket for debris or wear before seating a new edge; a damaged pocket will reduce insert life and surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG 12 04 08-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: 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, Code C)\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (0.79 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4762 inches (12.10 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\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches (5.16 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\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: T-Max P\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: 0.24 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 5724399\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51752384692530,"sku":"5724399","price":279.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af715bf1e535180f2a065f72858c9a65_33721af5-bca9-492f-80e6-b88bd919388e.jpg?v=1788927852","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5724399-cnmg432-mm-2025-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
