Manufactured to ANSI code DNMG431ESU and ISO code DNMG150404N-SU, it features a 55-degree diamond insert shape with a negative rake geometry and a neutral hand orientation. The T1500Z cermet substrate receives a PVD coating for enhanced surface hardness and thermal resistance. With a 1\/2 inch inscribed circle and a 1\/64 inch corner radius, this insert is built for finishing and semi-finishing passes where tight tolerances and surface quality are priorities. It is held in place by clamp and pin methods, suiting standard DNMG toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated primarily for steel workpiece materials (ISO material code P), making it a direct fit for general turning of carbon steels, alloy steels, and similar ferrous materials in production and job-shop environments. The ESU chip breaker geometry is designed to manage chip flow during light-to-moderate depth-of-pass operations. Typical applications include OD turning, facing, and light profiling on parts where dimensional consistency and finish quality are critical. Installation is performed by licensed machining professionals on properly maintained CNC or manual lathes with compatible DNMG toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eT1500Z cermet substrate with PVD coating for wear resistance on steel materials\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond (D) insert shape with DNMG431ESU ANSI designation\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch inscribed circle and 3\/16 inch insert thickness for rigid support\u003c\/li\u003e\n  \u003cli\u003e1\/64 inch corner radius (0.0156 inches decimal) for controlled surface finish\u003c\/li\u003e\n  \u003cli\u003eESU chip breaker promotes consistent chip evacuation on steel turning operations\u003c\/li\u003e\n  \u003cli\u003eNegative rake, neutral hand — compatible with standard DNMG clamp-and-pin toolholders\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO 13399 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for standard DNMG-style toolholders that accept a 55-degree diamond insert with clamp and pin holding.

Always power down and lock out the machine spindle before changing inserts. Inspect the insert seat and shim for chips or damage before seating a new insert to ensure proper support and prevent premature edge failure. Do not exceed the toolholder manufacturer recommended depth of cut or feed rate for this insert size and geometry.\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\u003eInsert Material\u003c\/strong\u003e: Cermet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: T1500Z\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: PVD Coated\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\u003eChip Breaker\u003c\/strong\u003e: ESU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (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\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\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 Holding Method\u003c\/strong\u003e: Clamp and Pin\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: 0.015 pounds\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\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: 194AAPK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51744920535346,"sku":"194AAPK","price":227.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8e85b41f646b723fd9673739f820e27.jpg?v=1788862233","url":"https:\/\/voomisupply.com\/products\/sumitomo-194aapk-cermet-turning-insert-dnmg431esu","provider":"Voomi Supply","version":"1.0","type":"link"}
