It carries the AC820P grade designation and features an 80-degree diamond insert shape with a neutral hand orientation and a negative rake angle. The 1\/2-inch inscribed circle and 0.0313-inch corner radius make this a versatile choice for medium to finishing turning operations. The EMU chip breaker geometry and CVD coating process are engineered to maintain edge integrity across a range of cutting conditions in steel and stainless steel applications. Installed by machinists and CNC turning professionals, this insert is suited for production environments requiring consistent tool life and predictable chip control.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for turning operations on steel and stainless steel workpiece materials, corresponding to ISO material codes P and M. The AC820P grade with CVD coating is well-matched to continuous and mildly interrupted cutting passes on CNC lathes and turning centers. The CNMG geometry is compatible with standard negative-rake CNMG toolholders using clamp and pin holding methods. The EMU chip breaker profile supports a broad range of depths of cut and feed rates commonly encountered in general-purpose turning of ferrous alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC820P CVD-coated solid carbide grade engineered for steel and stainless steel turning\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with neutral hand for flexible toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eEMU chip breaker geometry for reliable chip control across varied feed and depth conditions\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch inscribed circle with 1\/32-inch corner radius for medium to light finishing passes\u003c\/li\u003e\n  \u003cli\u003eNegative rake geometry with zero-degree relief angle for high edge strength\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO 13399 standards with ISO code CNMG120408N-MU\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard negative-rake CNMG turning toolholders utilizing clamp and pin clamping methods.

Power down and lock out the machine spindle before seating or replacing the insert. Inspect the toolholder pocket and seating surfaces for chips or debris before installing the new insert to ensure proper contact and prevent premature edge failure. Follow the toolholder manufacturer torque procedure for the clamping screw to avoid cracking the carbide substrate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: CNMG432EMU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG120408N-MU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC820P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated (CVD)\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 Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code 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: 1\/2 inch (0.5000 inch \/ 12.70 mm)\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 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inch \/ 0.03 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 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\u003eChip Breaker\u003c\/strong\u003e: EMU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CN\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\u003eMaterial Grade\u003c\/strong\u003e: C5A, C6, C7, C8\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: 0.075 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: 19RJAFI\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51730487410994,"sku":"19RJAFI","price":188.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba427cce863cfe784cd9f2d252b4e9b9.jpg?v=1788718320","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rjafi-turning-insert-cnmg432emu-ac820p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
