It carries the ANSI designation DNMG431ENG and ISO code DNMG150404N-UG, placing it in the DN series with a 55-degree diamond shape, neutral hand orientation, and a manufacturer grade of AC820P. The insert features a 0.5000-inch inscribed circle, a 0.6102-inch length, and a 0.0156-inch corner radius. The ENG chip breaker geometry and CVD coating make it well suited for moderate to high-speed turning of steel and other primary workpiece materials classified under P and M material groups. Licensed CNC machinists and toolroom technicians are the primary installers of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is applied in turning operations targeting steel and mixed-material workpieces in both production and job-shop environments. The AC820P grade with CVD coating provides wear resistance at elevated cutting speeds. The negative rake geometry and N clearance code make it appropriate for rigid, stable toolholder setups. Compatible material grades include C5A, C6, C7, and C8, covering a range of coated carbide applications on steel (P) and stainless or mixed-material (M) workpieces. Typical use cases include roughing and semi-finishing passes on bar stock, shafts, and cylindrical components on CNC or manual lathes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eANSI code DNMG431ENG with ISO code DNMG150404N-UG for cross-reference compatibility\u003c\/li\u003e\n\u003cli\u003eAC820P grade CVD-coated solid carbide construction for extended tool life on steel\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape (shape code D) with negative rake for stable cutting forces\u003c\/li\u003e\n\u003cli\u003eENG chip breaker geometry designed for controlled chip evacuation during turning\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits standard DNMG-style toolholders with clamp and pin holding method\u003c\/li\u003e\n\u003cli\u003e0.0156-inch corner radius balances edge strength with surface finish requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in DNMG-style toolholders that accept clamp and pin insert holding.

Use the appropriate torque wrench and manufacturer-specified clamp screw to seat the insert without over-torquing the clamp. Inspect the insert pocket and clamp for wear or debris before seating a new insert. Verify toolholder compatibility with the DNMG431 seat size and the clamp-and-pin holding method before use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: DNMG431ENG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG150404N-UG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55 degrees, shape code D)\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: 0.6102 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\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 Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC820P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: ENG\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: P (Steel), M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5A, C6, C7, C8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\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: 0.075 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: SUMITOMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 19RJ893\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51738424312114,"sku":"19RJ893","price":239.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/edb7e66cc6ce6a3ef76e4e4c954feaec.jpg?v=1788799344","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rj893-turning-insert-dnmg431eng-ac820p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
