Manufactured from solid carbide and finished with a CVD coating in the AC830P grade, this insert delivers reliable performance across a range of metalcutting applications. The 80-degree diamond shape (Insert Shape Code C) with a negative rake angle provides strong cutting edge support. The EMU chip breaker geometry is suited for moderate to light cutting conditions. With a 3\/4-inch inscribed circle and a 1\/16-inch corner radius, this insert fits standard CNMG toolholders used throughout production and job-shop environments. Installation and replacement are performed by qualified machinists or CNC setup technicians.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning steel and stainless steel workpiece materials, classified under ISO material groups P and M. The AC830P grade and CVD coating make it a practical choice for both continuous and mildly interrupted cuts on low-alloy steels, carbon steels, and austenitic stainless steels. The neutral hand orientation allows use in both right-hand and left-hand toolholder configurations, adding flexibility on multi-operation setups. Typical applications include shaft turning, facing, and profiling on production lathes in industrial and manufacturing settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC830P solid carbide grade with CVD coating for extended tool life on steel and stainless workpieces\u003c\/li\u003e\n  \u003cli\u003eCNMG insert style with 80-degree diamond shape and negative rake for strong edge support\u003c\/li\u003e\n  \u003cli\u003eEMU chip breaker geometry suited for moderate to light depth-of-cut turning\u003c\/li\u003e\n  \u003cli\u003eNeutral hand insert — compatible with both right-hand and left-hand CNMG toolholders\u003c\/li\u003e\n  \u003cli\u003e1\/16-inch corner radius balances surface finish quality and cutting edge strength\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method for secure, repeatable seating in standard toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO 13399 standards; ISO code CNMG190616N-MU\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style indexable insert for standard CNMG toolholders accepting a 3\/4-inch inscribed circle insert with clamp and pin holding.

Ensure the toolholder pocket and seating surfaces are clean and free of chips before seating the insert. Use the manufacturer-specified clamp screw torque as listed in the toolholder documentation — do not estimate torque values. Inspect the insert for cracks or edge damage before each use; do not run a damaged insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: CNMG644EMU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG190616N-MU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC830P\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: CVD Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees, Code C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: EMU\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\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: 3\/4 inches (0.7500 inches \/ 19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.7598 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0625 inches (1\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.3130 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 Material\u003c\/strong\u003e: Steel (P), Stainless Steel (M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Universal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C5A, C6\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: 0.075 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: 19RBAFO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51729291247922,"sku":"19RBAFO","price":392.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80d00ce694e45b31b2809cbf48a55670.jpg?v=1788702503","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rbafo-turning-insert-cnmg644emu-ac830p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
