This solid carbide insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, providing thermal resistance and wear protection during continuous and interrupted cutting passes. The insert carries a 55-degree diamond shape (ISO code D), a neutral hand orientation, and a 0.0313-inch corner radius. With 4 usable cutting edges and a 0.5789-inch length, it delivers consistent performance on demanding workpiece materials. Licensed machinists and CNC operators handling production turning work are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is designed primarily for turning stainless steel workpieces, classified under ISO workpiece material code M. It belongs to the SANDVIK COROMANT T-Max P series, which is optimized for external and internal turning where chip control and edge stability are critical. The QM chip breaker geometry is suited for medium machining conditions where controlled chip formation improves surface finish and reduces tool pressure. Typical applications include production turning on CNC lathes in job shops, aerospace component machining, and general industrial manufacturing environments requiring reliable performance on austenitic and duplex stainless grades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape provides a strong cutting edge geometry\u003c\/li\u003e\n\u003cli\u003eQM chip breaker geometry for controlled chip formation in medium turning operations\u003c\/li\u003e\n\u003cli\u003e4 cutting edges per insert for cost-effective indexing\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation for flexible toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eT-Max P series construction engineered for stainless steel and difficult-to-machine alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with DNMG-style toolholders that accept clamp and pin insert holding methods.

Power down and lock out the machine spindle before indexing or replacing inserts. Use a torque wrench calibrated to the toolholder manufacturer's specified clamp screw value — do not estimate torque by feel. Inspect the insert pocket seat and clamping components for wear or debris before seating the new insert to ensure proper contact and edge position.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG 15 04 08-QM 2025\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 2025\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55-degree included angle)\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: QM\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: 0.5789 inches (14.70 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: 0.0313 inches (0.79 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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 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: 5731819\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51728615801138,"sku":"5731819","price":290.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d63cad299f8d66adc3f1886b081cdd0.jpg?v=1788694007","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5731819-dnmg432-qm-2025-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
