Manufactured to ANSI code DNMG431EEX and ISO code DNMG150404N-EX, this insert features a 55-degree diamond shape with a neutral hand orientation. The AC630M grade substrate is finished with an Al2O3 (aluminum oxide) CVD coating, which provides thermal resistance and wear protection during medium to finish turning cuts. The 1\/64-inch corner radius supports fine surface finish requirements while the positive rake geometry helps reduce cutting forces on the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning operations on stainless steel and other difficult-to-machine materials where edge toughness and coating integrity are critical. The EEX chip breaker geometry is engineered to manage chip evacuation in continuous and light interrupted cuts. Typical applications include shaft turning, facing, and profile work on CNC turning centers in job shop, production machining, and aerospace component environments. The insert seats using a clamp and pin holding method, which is standard across most DNMG-compatible toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with AC630M grade for stainless steel and challenging alloy applications\u003c\/li\u003e\n  \u003cli\u003eAl2O3 CVD coating for high-temperature wear resistance at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape with EEX chip breaker for controlled chip formation\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 16 degrees reduces cutting forces and heat generation\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO 13399 standards for insert identification and data exchange\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in DNMG-style toolholders that accept a clamp and pin holding method.

Use the appropriate torx or hex key as specified by the toolholder manufacturer when tightening the clamp screw — do not exceed the toolholder manufacturer's specified torque. Inspect the insert seat and clamp pocket for chips or debris before seating the new insert. Verify insert orientation and chip breaker direction are correct for the intended cutting direction before resuming operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: DNMG431EEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG150404N-EX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55 degrees)\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: AC630M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Al2O3\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: EEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 16 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inches)\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 (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\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\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\u003eMaterial Grade\u003c\/strong\u003e: C5, C5A, C6, C7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 19PW169\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51745345077554,"sku":"19PW169","price":271.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a207f4de264d9d216fb9e6b386fe505.jpg?v=1788863602","url":"https:\/\/voomisupply.com\/products\/sumitomo-19pw169-turning-insert-dnmg431eex-ac630m-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
