It carries the ANSI insert code DNMG431 and ISO code DNMG150404, with a 55-degree diamond (rhombic) shape and neutral hand orientation. The insert is manufactured to grade AC830P, a CVD-coated carbide grade engineered for moderate wear resistance and toughness across steel and stainless steel workpieces. With a 0.5 inch inscribed circle and a 0.0156 inch corner radius, this insert suits both roughing and medium machining operations. Chip breaker designation ENG further supports controlled chip evacuation during those cut types. Licensed machinists and CNC operators working in production turning environments are the primary users of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning steel (ISO P) and stainless steel (ISO M) workpiece materials. The AC830P grade provides a balance of wear resistance and toughness that handles variable stock conditions, interrupted cuts, and continuous finishing passes at medium to heavy chip loads. The ENG chip breaker geometry is optimized for roughing and medium machining. The insert is sold individually per package with a minimum order quantity of 10 units, making it appropriate for shop-floor replenishment in production machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD-coated AC830P carbide grade for steel and stainless steel cutting (ISO P and M materials)\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape (ANSI DNMG431 \/ ISO DNMG150404) with neutral hand\u003c\/li\u003e\n\u003cli\u003eENG chip breaker geometry rated for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003eNegative rake and negative side clearance (clearance code N) for clamp or pin holding methods\u003c\/li\u003e\n\u003cli\u003e0.0156 inch corner radius for consistent edge geometry across production runs\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI and ISO 13399 insert standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use insert for CNC turning tool holders that accept DNMG431 (ANSI) or DNMG150404 (ISO) insert geometry with clamp or pin holding.

Power down and lock out the machine spindle before seating or indexing any insert. Seat the insert fully against the pocket locating surfaces before tightening the clamp or pin to avoid micro-movement during cutting. Inspect the insert pocket for chips or debris prior to installation, as contamination under the insert can cause premature edge failure or poor surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNMG431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNMG150404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC830P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 degrees\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: ENG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing and Medium Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 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\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\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\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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: Steel (P), Stainless Steel (M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C5A, C6\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 insert per package\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: 19RB893\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51729877336370,"sku":"19RB893","price":270.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/caeb73738d86ee8d7161ee5823be620d.jpg?v=1788709677","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rb893-turning-insert-dnmg431-ac830p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
