It carries the BN2000 manufacturer grade, which is engineered for high wear resistance with moderate toughness, making it well-suited for interrupted and continuous cuts on hardened ferrous workpieces. The insert features a 35-degree diamond (rhombic) shape, a 3\/8 inch inscribed circle, and a 1\/64 inch corner radius. It is uncoated, with a bright finish and a negative rake and negative side clearance geometry. ANSI Insert Code is VNMA331; ISO Insert Code is VNMA160404.\u003c\/p\u003e\u003cp\u003eThis insert is used in turning applications on hardened steels, hardened cast irons, and other hard materials classified under ISO workpiece material group H. It is intended for use in precision CNC turning centers where tight tolerances and long tool life on hard materials are required. The VNMA insert style with clamp and pin holding method suits rigid toolholding setups common in production and job-shop environments targeting hardened workpiece finishing operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePCBN insert material provides high wear resistance for hardened workpiece machining\u003c\/li\u003e\n\u003cli\u003eBN2000 grade balances wear resistance with moderate toughness for both continuous and light interrupted cuts\u003c\/li\u003e\n\u003cli\u003e35-degree diamond insert shape enables access in tight-clearance turning profiles\u003c\/li\u003e\n\u003cli\u003eNegative rake and negative side clearance geometry supports strong cutting edge retention\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish — no coating delamination risk on precision finishing passes\u003c\/li\u003e\n\u003cli\u003eCompatible with ANSI and ISO 13399 tooling standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in VNMA-style toolholders accepting a 331 ANSI size code insert.

Power down and lock out the machine spindle before seating or removing the insert. Use the appropriate torque wrench for the clamp screw — refer to the toolholder manufacturer specifications for clamping torque. Inspect the insert seat and shim for debris or damage before installation to ensure proper seating and prevent edge chipping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VNMA331\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VNMA160404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: PCBN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: BN2000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: V - Diamond (Rhombic) 35 degrees\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\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 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\u003eInsert Length\u003c\/strong\u003e: 0.1102 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\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\u003eCoating\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: A\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: Hard Material (ISO Code H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade Characteristics\u003c\/strong\u003e: Hardened Materials - High to Moderate Wear Resistance and Toughness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 16JRCWQ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51731443548466,"sku":"16JRCWQ","price":61.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d2218c818f6f021323f22c3e728b0e5.jpg?v=1788731205","url":"https:\/\/voomisupply.com\/products\/sumitomo-16jrcwq-pcbn-turning-insert-bn2000-35-deg-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
