The insert carries an 80-degree diamond shape (ANSI code CNMG432ESU, ISO code CNMG120408N-SU) with a neutral hand orientation and a positive rake angle of 13 degrees. Manufacturer grade AC520U is engineered for demanding cutting applications. The ESU chip breaker geometry and 0.0313-inch corner radius combine to manage chip flow and reduce cutting forces in finish and semi-finish turning operations. Licensed machinists and CNC operators working in production turning environments are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning operations on stainless steel and superalloy workpiece materials, corresponding to ISO material codes M and S. The ESU chip breaker geometry is suited for medium to finish passes where controlled chip evacuation and edge stability are priorities. Typical use cases include CNC lathe work on aerospace alloys, medical-grade stainless components, and other high-strength materials where TiAlN and AlCrN coatings provide heat resistance and wear life advantages over uncoated or CVD-coated alternatives.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiAlN and AlCrN dual-layer coating for elevated heat resistance and extended tool life on hard-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003eProprietary Super ZX coating designation from Sumitomo targeting stainless steel and superalloy applications\u003c\/li\u003e\n  \u003cli\u003eESU chip breaker geometry designed for controlled chip formation in medium to finish turning passes\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape provides two usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 13 degrees reduces cutting forces and heat generation at the edge\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods for secure seating in standard CNMG toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO 13399 standards for dimensional interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style turning toolholders that accept a 1\/2-inch inscribed circle insert with clamp or pin clamping.

Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully into the toolholder pocket and verify the clamping screw or pin is torqued per the toolholder manufacturer's specification before resuming cuts. Do not continue using an insert that shows visible edge chipping, cratering, or flank wear beyond acceptable limits, as degraded edges on high-strength materials can cause workpiece damage or unpredictable tool failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: CNMG432ESU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG120408N-SU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\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: AC520U\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN and AlCrN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProprietary Coating\u003c\/strong\u003e: Super ZX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: ESU\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: 13 degrees\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\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5079 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: 0.0313 inches (1\/32 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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Stainless Steel, Superalloy (ISO M and S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CN\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: 0.04 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: 19HWAPA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51730539577650,"sku":"19HWAPA","price":171.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d994d303de282a4a4d60884e8e767876_8d9a4630-d48b-4b73-aad8-bff641bd0f61.jpg?v=1788719238","url":"https:\/\/voomisupply.com\/products\/sumitomo-19hwapa-turning-insert-cnmg432esu-ac520u-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
