It carries the ANSI code NUCCGA32.51 and ISO code NU-CCGW09T304, and uses an uncoated BN2000 grade PCBN material. The insert features an 80-degree diamond shape (C-code), a 3\/8-inch inscribed circle, and a 1\/64-inch (0.0156 inch) corner radius. With a positive rake geometry and a 7-degree relief angle, it is designed to reduce cutting forces and maintain edge stability when machining hard or abrasive workpiece materials. A screw-holding method secures the insert in compatible toolholders. This insert is handled and installed by machinists and CNC turning specialists.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning operations on cast iron, hardened steel, and superalloy workpieces, corresponding to primary workpiece material codes H, K, and S. It is well-suited to finish and semi-finish turning passes where tight tolerances and surface finish quality are required. The single cutting edge and G-tolerance class contribute to dimensional accuracy in demanding production and job-shop environments. The BN2000 grade is selected for its wear resistance and thermal stability at elevated cutting temperatures typical of hard-turning operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePCBN insert material (BN2000 grade) for hard-turning and high-speed machining\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with positive rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle (0.3750 inch) with G tolerance class for tight dimensional control\u003c\/li\u003e\n\u003cli\u003e1\/64-inch corner radius (0.0156 inch) for finish and semi-finish turning\u003c\/li\u003e\n\u003cli\u003eScrew-holding method compatible with standard CCG-series toolholders\u003c\/li\u003e\n\u003cli\u003eUncoated construction; meets ANSI and ISO 13399 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw-clamp toolholders accepting CCGA\/CCGW-style inserts in the CCG series.

Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before seating or removing the insert. Use the appropriate torx or hex key to tighten the clamping screw to the toolholder manufacturer's specified torque. Inspect the insert seat and shim for wear or debris before installing a new insert to maintain accurate tool geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: NUCCGA32.51\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: NU-CCGW09T304\u003c\/li\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, C-code)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.0984 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1730 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hardened Steel, Superalloy (H, K, S)\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: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 16JRW6P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51747380068658,"sku":"16JRW6P","price":80.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0883557bc77f0e4683a1590f80374236.jpg?v=1788879234","url":"https:\/\/voomisupply.com\/products\/sumitomo-16jrw6p-pcbn-turning-insert-3-8-inch-ic-bn2000","provider":"Voomi Supply","version":"1.0","type":"link"}
