Carrying the ANSI designation TNMG432EMU and ISO code TNMG220408N-MU, this insert features a 60-degree triangular shape, a negative rake geometry, and a neutral hand orientation. The AC830P grade coating provides wear resistance suited to a range of ferrous and stainless workpiece materials. With an inscribed circle of 0.5 inches and a corner radius of 0.03 inches, it delivers consistent edge performance in medium to finishing cut applications. Installation requires a compatible clamp and pin holding system.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in production and job-shop turning operations where consistent surface finish and dimensional accuracy are required. The EMU chip breaker geometry supports stable chip control across varying feed rates. Primary workpiece materials are categorized as P (carbon and alloy steels) and M (stainless steels), with secondary universal application. It is suited to both light finishing and moderate roughing passes when paired with an appropriate toolholder.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC830P manufacturer grade with CVD coating for extended tool life on steel and stainless\u003c\/li\u003e\n  \u003cli\u003eTNMG432EMU chip breaker geometry supports controlled chip evacuation across varied feed rates\u003c\/li\u003e\n  \u003cli\u003eNegative rake, neutral hand orientation compatible with standard TNMG clamp-and-pin toolholders\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular insert shape provides three usable cutting edges\u003c\/li\u003e\n  \u003cli\u003e0 degrees relief angle (clearance code N) with tolerance code M for consistent seating\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO 13399 standards for interchangeability and documentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TNMG-style clamp and pin toolholders accepting a 0.5-inch inscribed circle triangular insert.

Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before changing inserts. Seat the insert fully against the pocket locating surfaces before tightening the clamp to avoid edge chipping or premature wear. Follow the toolholder manufacturer torque guidelines for the clamp screw.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: TNMG432EMU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TNMG220408N-MU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\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 Process\u003c\/strong\u003e: CVD\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\u003eChip Breaker\u003c\/strong\u003e: EMU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.8661 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: 0.0313 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.203 inches\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: M (Stainless Steel), P (Carbon and Alloy Steel)\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\u003eSeries\u003c\/strong\u003e: TN\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: 19RBAFC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51733217444146,"sku":"19RBAFC","price":212.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4e72ecd1ba1650ad9eaf17c6521c8bb.jpg?v=1788752863","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rbafc-turning-insert-tnmg432emu-ac830p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
