Rated to manufacturer grade AC820P, this insert features an 80-degree diamond shape, a neutral hand orientation, and a positive rake angle of 3 degrees. The inscribed circle measures 0.5 inches, the corner radius is 0.0156 inches (1\/64 inch), and the insert length runs 0.5079 inches. It is designed for precision metal-removal operations on CNC and manual lathes, primarily targeting steel workpiece materials. Machinists and tool-room technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning and facing operations on steel in both production and job-shop environments. The EGE chip breaker geometry supports controlled chip evacuation across a range of depths of cut and feed rates typical to steel turning. The AC820P grade with Al2O3 CVD coating is well-matched to general-purpose steel machining where heat resistance and edge wear are the primary concerns. This insert conforms to ANSI code CNMG431EGE and ISO code CNMG120404N-GE per ANSI and ISO 13399 standards, making cross-referencing to compatible toolholders straightforward.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC820P manufacturer grade with Al2O3 CVD coating for heat and wear resistance in steel turning\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (Shape Code C) for versatile turning and facing approaches\u003c\/li\u003e\n  \u003cli\u003eEGE chip breaker geometry designed for controlled chip formation in steel\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with a wide range of CNMG-style toolholders\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (3 degrees) reduces cutting forces and heat generation at the edge\u003c\/li\u003e\n  \u003cli\u003eDual holding method: clamp and pin for secure seating in the insert pocket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eConforms to ANSI code CNMG431EGE and ISO code CNMG120404N-GE.

Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Seat the insert firmly in the pocket and verify clamp and pin engagement before resuming any cutting operation. Inspect the insert pocket and seating surfaces for debris or damage that could affect insert stability and dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC820P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\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 Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Al2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: CNMG431EGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG120404N-GE\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 (3\/16 inch)\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\u003eRake Angle\u003c\/strong\u003e: 3 degrees (Positive)\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: EGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eSeries\u003c\/strong\u003e: CN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel (Code P)\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: 0.025 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: 19RJCAY\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51738847576370,"sku":"19RJCAY","price":197.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8fd535e92de93367c0400cb7bae35cdc.jpg?v=1788805490","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rjcay-turning-insert-cnmg431ege-ac820p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
