Manufactured to ANSI and ISO 13399 standards, this insert carries the ANSI code TPG322 and ISO code TPG160308. It features an AC820P grade with a CVD coating process, a 60-degree triangular shape, and a positive rake with positive side clearance. The inscribed circle measures 3\/8 inches, the insert thickness is 1\/8 inches, and the corner radius is 1\/32 inches. Licensed CNC machinists and tool crib operators use this insert for high-wear-resistance to moderate-wear-resistance turning on steel and cast iron workpieces.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning applications on steel (ISO P) and cast iron (ISO K) workpieces where high wear resistance through moderate wear resistance and toughness are required. The flat-top chip breaker geometry and single cutting edge design make it appropriate for stable, controlled chip formation in both roughing and finishing passes on CNC lathes and turning centers. It is clamp-held and fits standard TPG-style insert pockets per ANSI and ISO 13399 tooling systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAC820P grade with CVD coating for extended tool life on steel and cast iron\u003c\/li\u003e\n\u003cli\u003eTPG322 ANSI \/ TPG160308 ISO insert code for direct toolholder compatibility\u003c\/li\u003e\n\u003cli\u003e60-degree triangle shape with positive rake and 11-degree relief angle\u003c\/li\u003e\n\u003cli\u003eFlat-top chip breaker for predictable chip control\u003c\/li\u003e\n\u003cli\u003eSingle cutting edge with clamp-style holding method\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO 13399 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit turning insert for TPG-style clamp toolholders conforming to ANSI and ISO 13399 specifications.

Power down and lock out the machine spindle before seating or replacing the insert. Ensure the insert pocket and clamp surfaces are free of chips and debris before securing the insert with the appropriate clamp screw torque per the toolholder manufacturer's specifications. Do not exceed the cutting parameter ranges recommended for the AC820P grade and the workpiece material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TPG322\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TPG160308\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TPGN160308\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: T - Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4331 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inches (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0313 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC820P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Cast Iron (K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5A, C6, C7, C8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: TP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.075 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: 12RJ712\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51732553531698,"sku":"12RJ712","price":210.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/917ea7aaaab309a92821590a64a8ef89.jpg?v=1788744387","url":"https:\/\/voomisupply.com\/products\/sumitomo-12rj712-turning-insert-tpg322-ac820p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
