It carries the AC520U manufacturer grade with a dual-layer PVD coating of TiAlN and AlCrN — marketed under Sumitomo's Super ZX designation — which provides high heat resistance and edge stability during interrupted and continuous cuts. The insert measures 0.5079 inches in length with a 1\/2-inch inscribed circle and a 0.0078-inch corner radius. The ESU chip breaker geometry and neutral hand orientation make this insert well-suited for finishing and semi-finishing passes. Licensed machinists and CNC operators install this class of insert in production turning applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning stainless steel, superalloys, and titanium — secondary workpiece material codes M and S. The ESU chip breaker with a positive rake angle of 13 degrees is optimized for controlled chip evacuation in tough, work-hardening materials. It fits standard CNMG-style toolholders that accept a 1\/2-inch inscribed circle, 3\/16-inch thick diamond insert with a clamp-and-pin holding method. Typical applications include aerospace component turning, medical part machining, and industrial equipment manufacturing where thermal resistance and edge life in difficult alloys are the primary concerns.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC520U grade with PVD-applied TiAlN and AlCrN Super ZX dual coating for thermal stability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eESU chip breaker geometry optimized for stainless steel, superalloy, and titanium turning\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 13 degrees reduces cutting forces on work-hardening materials\u003c\/li\u003e\n  \u003cli\u003eNeutral hand insert fits right- and left-hand compatible toolholder setups\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method provides secure seating under high cutting loads\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO 13399 standards; ANSI code CNMG430.5ESU, ISO code CNMG120402N-SU\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style toolholders accepting a 1\/2-inch inscribed circle, 3\/16-inch insert thickness, and clamp-and-pin retention.

Use the appropriate torque wrench for the clamp screw — refer to the toolholder manufacturer's specification sheet for the correct value. Inspect the insert pocket for wear, debris, or damage before seating the new insert, and confirm the insert is fully seated against all locating surfaces before resuming cutting. Minimum order quantity for this insert is 10 pieces; plan tooling inventory accordingly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: CNMG430.5ESU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG120402N-SU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC520U\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN and AlCrN (Super ZX)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eInsert Length\u003c\/strong\u003e: 0.5079 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\u003eCorner Radius\u003c\/strong\u003e: 0.0078 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\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\u003eChip Breaker\u003c\/strong\u003e: ESU\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\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Stainless Steel, Superalloy, Titanium\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\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: 0.01 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: 19HWBWM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51746418032946,"sku":"19HWBWM","price":172.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d994d303de282a4a4d60884e8e767876_93943ec5-7bc8-42c8-8636-313cd76c1977.jpg?v=1788869852","url":"https:\/\/voomisupply.com\/products\/sumitomo-19hwbwm-turning-insert-cnmg430-5esu-ac520u-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
