It carries a 35-degree diamond (rhombic) insert shape with a neutral hand orientation and a negative rake and negative side clearance geometry. The inscribed circle measures 3\/8 inches, insert thickness is 3\/16 inches, and the corner radius is 1\/64 inches. This insert is engineered for finishing and light machining operations and is suited to machinists and CNC turning specialists working on steel and stainless steel components in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 19RBAPR is designed for finishing and light machining passes on steel (ISO P) and stainless steel (ISO M) workpiece materials. The AC830P grade provides moderate wear resistance balanced with toughness, making it effective across a broad range of cutting conditions within those material groups. It is held via clamp or pin-lock tooling systems and conforms to both ANSI and ISO 13399 standards. Typical applications include OD turning on CNC lathes where tight tolerances and surface finish are the primary objectives.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD-coated solid carbide construction in grade AC830P for balanced wear resistance and toughness\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond (V-shape, rhombic) insert geometry for access to tight shoulder angles\u003c\/li\u003e\n  \u003cli\u003eESU chip breaker geometry optimized for finishing and light machining cuts\u003c\/li\u003e\n  \u003cli\u003eNegative rake and negative side clearance (clearance code N, tolerance code M) for rigid, stable cutting\u003c\/li\u003e\n  \u003cli\u003eCompatible with both clamp and pin-lock insert holding methods\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO 13399 standards; ISO code VNMG160404N-SU\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in VNMG-style toolholders that accept 331 (ISO 160404) series inserts with clamp or pin-lock holding methods.

Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully and evenly against the toolholder pocket before tightening the clamp or pin to prevent micro-movement under cutting load. Inspect the insert seating pocket for chips or debris before each insert change to maintain accurate tool geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VNMG331\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VNMG160404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Full Code\u003c\/strong\u003e: VNMG160404N-SU\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\u003eCoating Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: V - Diamond (Rhombic) 35 Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\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\u003eChip Breaker\u003c\/strong\u003e: ESU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing; Light Machining\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: 0.6535 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp; Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Stainless Steel (M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5; C5A; C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI; ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.075 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 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: 19RBAPR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51738518257970,"sku":"19RBAPR","price":278.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/053d3d443a5d8e5b5326f565e4475050.jpg?v=1788800538","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rbapr-turning-insert-vnmg331-ac830p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
