Manufactured in the AC8025P grade with a CVD coating, this insert is engineered primarily for steel workpieces. It features a 55-degree diamond shape (insert shape code D), a 0.5-inch inscribed circle, and a 1\/64-inch corner radius. The negative rake geometry and neutral hand orientation make it suitable for a range of turning, facing, and profiling operations. It is installed by machinists and CNC operators in production and job-shop environments where consistent tool life and surface finish on steel are required.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external and internal turning operations on steel components in both light and medium-duty cuts. The ESU chip breaker geometry is designed to control chip flow effectively during steel turning. The insert is held by clamp and pin methods and is compatible with DNMG-style toolholders following ANSI and ISO 13399 standards. Its ISO designation is DNMG150404N-SU, providing a direct cross-reference for toolholder selection and international procurement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC8025P CVD-coated solid carbide grade optimized for steel turning\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape for versatile turning and profiling\u003c\/li\u003e\n  \u003cli\u003eESU chip breaker geometry for controlled chip evacuation on steel\u003c\/li\u003e\n  \u003cli\u003eNegative rake, neutral hand geometry compatible with standard DNMG toolholders\u003c\/li\u003e\n  \u003cli\u003eANSI code DNMG431ESU and ISO code DNMG150404N-SU for cross-reference\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method for secure, repeatable seating\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 0.5-inch inscribed circle, 3\/16-inch thick diamond insert with clamp and pin retention, conforming to ANSI and ISO 13399 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator with the machine powered down and the spindle locked before changing inserts. Use the appropriate torx or clamp screw driver as specified by the toolholder manufacturer to seat the insert securely against the pocket. Inspect the toolholder pocket for chips or wear before seating a new insert. Follow the insert manufacturer and toolholder manufacturer guidelines for recommended cutting parameters when establishing feeds and speeds for the specific workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: DNMG431ESU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG150404N-SU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC8025P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 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\u003eInsert Length\u003c\/strong\u003e: 0.6102 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\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: CVD Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: ESU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\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\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 19P7APK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51728515137842,"sku":"19P7APK","price":33.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c2dbda30b8071f719af3ee6e1755a3a.jpg?v=1788692508","url":"https:\/\/voomisupply.com\/products\/sumitomo-19p7apk-carbide-turning-insert-dnmg431-ac8025p","provider":"Voomi Supply","version":"1.0","type":"link"}
