It features a triangular insert shape with a 60-degree included angle and a neutral hand orientation, making it suitable for a wide range of turning applications. The insert is manufactured from solid carbide and coated with aluminum oxide (Al2O3) via a CVD process using the AC820P grade, which provides thermal resistance and wear performance when cutting steel and similar materials. The 3\/8-inch inscribed circle and 1\/32-inch corner radius define its cutting geometry. This insert is installed and swapped by machinists and tool-and-die professionals on production turning equipment.\u003c\/p\u003e\n\u003cp\u003eThe 19RJ758 is suited for medium to finishing turning passes in steel workpiece applications, consistent with its P-grade (steel) secondary workpiece material designation. The TNMG332ENZ chip breaker geometry with a 4-degree positive rake angle helps manage chip formation during continuous cuts. The insert is compatible with standard TNMG-style insert toolholders that accept a 3\/8-inch inscribed circle insert. Typical deployment is in production machining environments where consistent tool life and dimensional accuracy are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC820P carbide grade with CVD-applied Al2O3 coating for wear and heat resistance in steel cutting\u003c\/li\u003e\n  \u003cli\u003eTNMG332ENZ chip breaker geometry with 4-degree positive rake angle for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003e0-degree relief angle (clearance code N) with tolerance code M for consistent seating and dimensional repeatability\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method for secure insert retention under cutting loads\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO 13399 standards; ISO code TNMG160408N-UZ\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard TNMG-style indexable insert toolholders accepting a 3\/8-inch inscribed circle triangular insert with clamp and pin holding.

Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench or clamp screw driver specified by the toolholder manufacturer when seating the insert — do not overtighten the clamp screw. Inspect the insert pocket and seating surface for chips or debris before installing a new insert to ensure proper seating and prevent insert rocking.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNMG\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: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees included angle)\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: ENZ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 4 degrees (Positive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6496 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1500 inches\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\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\u003eISO Code\u003c\/strong\u003e: TNMG160408N-UZ\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\u003ePackage Dimensions\u003c\/strong\u003e: 3.5 inches long, 1.5 inches wide, 0.44 inches high\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package (minimum order quantity: 10)\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: 19RJ758\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51750793904434,"sku":"19RJ758","price":148.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c345089bd385522cc9d2a830ef662e2f_a2d48520-165e-4a6e-a788-80ae3a117140.jpg?v=1788919779","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rj758-turning-insert-tnmg332enz-ac820p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
