It carries the AC5025S manufacturer grade and features a TiAlSiN coating applied via PVD process, marketed under the Absotech Bronze proprietary coating designation. This coating provides thermal resistance and wear protection suited to demanding cutting conditions. The insert has a negative rake angle, a neutral hand orientation, an 80-degree diamond shape, and a 1\/16 inch corner radius. It belongs to the AC5000S series and is held in place by a screw-clamp toolholder. Licensed machinists and CNC operators install and index this insert as part of routine tooling maintenance.\u003c\/p\u003e\u003cp\u003eThis insert is engineered with superalloy as its primary workpiece material, making it appropriate for turning nickel-based alloys, titanium, and similar difficult-to-machine materials common in aerospace, power generation, and defense applications. The EMU chip breaker geometry supports controlled chip evacuation at the cutting parameters typical for these materials. It conforms to ANSI and ISO 13399 standards, and its ISO code is CNMG120416N-MU, which allows direct cross-reference with toolholder catalogs specifying that pocket geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlSiN PVD coating (Absotech Bronze) for thermal stability and flank wear resistance in superalloy cutting\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (Shape Code C) for versatile turning and facing operations\u003c\/li\u003e\n\u003cli\u003eEMU chip breaker geometry engineered for superalloy chip control\u003c\/li\u003e\n\u003cli\u003eNegative rake, neutral hand — compatible with standard CNMG screw-clamp toolholders\u003c\/li\u003e\n\u003cli\u003eComplies with ANSI and ISO 13399 standards for interchangeable tooling documentation\u003c\/li\u003e\n\u003cli\u003eClearance Code N, Tolerance Code M for consistent seating and repeatability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw-clamp toolholders accepting CNMG 434 pocket geometry per ANSI and ISO 13399 specifications.

Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer — do not overtighten the clamping screw, as this can crack the carbide substrate. Inspect the toolholder pocket for chips or wear before seating a new insert. Always verify insert orientation and confirm the correct cutting edge is engaged before resuming machine operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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 degrees, Shape Code C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch\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: 1\/16 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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 4 degrees\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: Screw\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\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlSiN (Absotech Bronze)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: EMU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC5025S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: S20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloy (Code S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AC5000S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG120416N-MU\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 19T6AFK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51730592956722,"sku":"19T6AFK","price":26.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ffd64e95bf2f4e050dad0834b2a5883.jpg?v=1788720081","url":"https:\/\/voomisupply.com\/products\/sumitomo-19t6afk-turning-insert-cnmg-1-2-ic-diamond-80","provider":"Voomi Supply","version":"1.0","type":"link"}
