This insert uses a triangular (T) shape with a 60-degree included angle, an 11-degree relief angle, and a positive rake geometry that promotes clean chip evacuation and reduced cutting forces. The CVD-coated carbide substrate delivers a balance of wear resistance and toughness suited to interrupted and continuous cuts. At 0.6496 inches long with a 0.375-inch inscribed circle and a 0.0313-inch corner radius, it fits standard TPMR-style toolholders using a clamp-style holding method. Machinists and CNC operators in job shops and production environments install this insert for light to medium machining passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for primary workpiece materials including steel (ISO P), stainless steel (ISO M), and superalloys. The ENF chip breaker geometry supports light machining and medium machining operations, making it appropriate for finishing and semi-finishing passes where surface finish and dimensional accuracy are the priority. It carries material grade designations of C5, C5A, and C6, covering a broad range of steel and stainless alloy families encountered in general machining, aerospace component work, and precision part production.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC830P CVD-coated carbide grade with moderate wear resistance and high toughness for steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eENF chip breaker optimized for light and medium machining passes on steel, stainless steel, and superalloys\u003c\/li\u003e\n  \u003cli\u003eTriangular insert shape with 60-degree included angle and 11-degree positive relief angle for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003e0.0313-inch corner radius for semi-finishing and finishing operations requiring controlled surface finish\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible toolholder pairing\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO 13399 standards; ISO insert code TPMR160308N-SF\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TPMR-series clamp-style toolholders accepting a 3\/8-inch inscribed circle triangular insert.

Power down and lock out the machine spindle before changing inserts. Inspect the insert seat and clamp for chips or debris that could affect seating and indexing accuracy. Handle carbide inserts carefully to avoid chipping the cutting edges prior to use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TPMR322\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TPMR160308\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TPMR160308N-SF\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\u003eInscribed Circle\u003c\/strong\u003e: 0.375 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: 0.125 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\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC830P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C5A, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: CVD Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: ENF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Light Machining, Medium Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel, Superalloy\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: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: TPMR\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\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: 19RB486\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51737325797682,"sku":"19RB486","price":211.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73587ab0f3fb347edbd985eebbd437e6.jpg?v=1788787124","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rb486-turning-insert-tpmr322enf-ac830p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
