Manufactured from solid carbide with a CVD coating in the AC8025P grade, this insert is engineered primarily for cutting steel. It features a diamond (80-degree) insert shape, a neutral hand orientation, and a negative rake geometry. The inscribed circle measures 0.5 inches, insert length is 0.5079 inches, thickness is 0.1875 inches, and the corner radius is 0.0312 inches. The EMU chip breaker geometry supports controlled chip evacuation during turning passes. Licensed machinists and CNC operators install this insert in compatible CNMG toolholders as part of standard lathe setups.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external and internal turning applications on steel workpieces in both roughing and semi-finishing operations. The AC8025P carbide grade with CVD coating provides wear resistance and thermal stability under continuous and interrupted cuts. It carries ANSI code CNMG432EMU and ISO code CNMG120408N-MU, making it straightforward to cross-reference against toolholder specifications. The insert is held by clamp and pin methods, which is standard for CNMG-style seats in most indexable turning systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC8025P CVD-coated solid carbide grade optimized for steel turning\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with CNMG geometry and neutral hand\u003c\/li\u003e\n  \u003cli\u003eEMU chip breaker for controlled chip formation during turning\u003c\/li\u003e\n  \u003cli\u003eNegative rake, N clearance, M tolerance per ANSI and ISO 13399 standards\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0312 inches suits general-purpose finishing and semi-finishing passes\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin holding methods standard to CNMG toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style indexable turning toolholders that accept an insert with a 0.5-inch inscribed circle, 0.1875-inch thickness, and a 0.2031-inch hole diameter.

Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully in the toolholder pocket before tightening the clamp or pin to the toolholder manufacturer's specified procedure. Inspect the insert seat and clamp for chips or debris before securing the insert to ensure proper seating and tool-life performance.\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\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC8025P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: EMU\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\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: 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: 0.0312 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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\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\u003eWeight\u003c\/strong\u003e: 0.04 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: 19P7AFI\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51730647417138,"sku":"19P7AFI","price":197.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e79661e519d2d46174b472e7fb0bc052.jpg?v=1788720805","url":"https:\/\/voomisupply.com\/products\/sumitomo-19p7afi-turning-insert-cnmg432emu-ac8025p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
