It carries the AC510U manufacturer grade and features a dual-layer PVD coating — TiAlN and AlCrN — under SUMITOMO's proprietary Super ZX coating designation. This coating combination delivers high heat resistance and edge stability during interrupted and continuous cuts. The insert measures 0.5079 inches in length with a 0.5 inch inscribed circle and a 0.0156 inch corner radius. It is suited for production machining environments where consistent tool life and surface finish are critical. Machining technicians and CNC setup personnel are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for use on superalloy workpiece materials, making it applicable in aerospace, power generation, and high-temperature alloy machining contexts. The EEF chip breaker geometry is optimized for light to medium depth-of-cut finishing passes where chip control and surface integrity are priorities. The neutral hand orientation allows flexible toolholder pairing across standard CNMG-compatible boring bars and external turning toolholders. The CN series designation aligns with ISO code CNMG120404N-EF for international toolholder cross-referencing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC510U grade with PVD-applied TiAlN and AlCrN dual coating (Super ZX designation) for extended tool life on difficult alloys\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (Shape Code C) for strong cutting edge geometry with moderate clearance\u003c\/li\u003e\n  \u003cli\u003eEEF chip breaker designed for finishing operations with reliable chip evacuation\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard CNMG clamp-and-pin toolholders\u003c\/li\u003e\n  \u003cli\u003eRated for superalloy (ISO material code S) secondary workpiece material applications\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO 13399 standards for insert geometry and identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style clamp and pin toolholders accepting a 0.5 inch inscribed circle insert with a 0.2031 inch hole diameter.

Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key to the toolholder manufacturer's specified seating procedure — do not overtighten the clamp screw. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert to ensure full, stable seating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: AC510U\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: EEF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degree, Shape Code C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 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: 0.5 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\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 Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding 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\u003eSeries\u003c\/strong\u003e: CN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG120404N-EF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Superalloy (Code S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI and ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.5 inches L x 1.5 inches W x 0.44 inches H\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: 19HVCGN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51729674699058,"sku":"19HVCGN","price":180.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ea57c848d161b1ed8764b5fbd8f135d2.jpg?v=1788707601","url":"https:\/\/voomisupply.com\/products\/sumitomo-19hvcgn-turning-insert-cnmg431eef-ac510u-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
