Built to ANSI code 2NUCNGA432 and ISO code 2NU-CNGA120408, this insert features an 80-degree diamond shape with a 0.5-inch inscribed circle and a 0.0313-inch corner radius. The PCBN construction delivers the hardness and thermal stability required for interrupted or continuous cuts on hardened ferrous materials. It is installed by machinists and toolroom technicians on CNC lathes and turning centers configured for hard turning applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for hard turning applications in both production and job-shop environments targeting hardened steel components such as bearing races, shafts, and tool steel parts. The 80-degree diamond geometry provides a strong cutting edge with good clearance for profiling cuts. The 2-cutting-edge configuration extends usable insert life per unit. The clamp and pin holding method ensures secure seating in compatible toolholders, making it appropriate for high-speed, tight-tolerance turning passes where surface finish and dimensional accuracy are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePCBN insert material for cutting hardened steel (material grade H) without coolant degradation\u003c\/li\u003e\n\u003cli\u003eUncoated BN2000 grade  -  optimized for dry or semi-dry hard turning\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (ANSI shape code C) for strong nose geometry\u003c\/li\u003e\n\u003cli\u003e0.0313-inch corner radius for balance between edge strength and surface finish\u003c\/li\u003e\n\u003cli\u003e2 cutting edges per insert for extended service per piece\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method for rigid, repeatable toolholder seating\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO 13399 standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-specification PCBN turning insert for CNC lathes and turning centers using CNGA-style toolholders with clamp and pin retention, per ANSI 2NUCNGA432 and ISO 2NU-CNGA120408 designations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before seating or replacing the insert. Use the correct clamp and pin hardware specified for CNGA-style holders to prevent insert movement under cutting loads. Do not exceed the toolholder or machine manufacturers recommended depth of cut or feed rate for PCBN inserts on hardened workpieces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Polycrystalline Cubic Boron Nitride (PCBN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: BN2000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees, Shape Code C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: 2NUCNGA432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: 2NU-CNGA120408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.0945 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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: Hardened Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: A\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 and 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: 16JRCTS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51740002189618,"sku":"16JRCTS","price":94.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fe4d60e2f82482b5310ffc32412e317.jpg?v=1788821356","url":"https:\/\/voomisupply.com\/products\/sumitomo-16jrcts-pcbn-turning-insert-uncoated-bn2000","provider":"Voomi Supply","version":"1.0","type":"link"}
