It carries the ANSI code 2NUDCGA32.51 and ISO code 2NU-DCGW11T304, confirming compliance with ANSI and ISO 13399 standards. The insert features a 55-degree diamond shape with a positive rake geometry and a 7-degree relief angle, producing a strong, sharp cutting edge suited for demanding interrupted and continuous cuts. Grade BN1000 PCBN material delivers the hardness and thermal stability required for high-speed turning without a coating. Machinists and tooling specialists install this insert into compatible screw-lock toolholders for DCG-series inserts.\u003c\/p\u003e\u003cp\u003eThis insert is engineered for turning hardened steel, cast iron, and superalloys — workpiece material codes H, K, and S. Typical applications include finish and semi-finish turning of hardened bearing races, brake rotors, camshafts, and turbine components where surface finish and dimensional accuracy are critical. The neutral hand orientation suits both left- and right-hand cut configurations depending on toolholder setup. With only 2 cutting edges and a 0.0156-inch corner radius, the 161NWCJ is oriented toward precision work at controlled depths rather than heavy stock removal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePCBN grade BN1000 uncoated insert for hardened steel, cast iron, and superalloy turning\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape (Shape Code D) with positive rake and 7-degree relief angle\u003c\/li\u003e\n\u003cli\u003e3\/8-inch (0.3750-inch) inscribed circle with 0.0156-inch (1\/64-inch) corner radius\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut 0.0150 inches for precision finish and semi-finish passes\u003c\/li\u003e\n\u003cli\u003eScrew-lock holding method with clearance code C and tolerance code G\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI and ISO 13399 standards; chip breaker style A\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw-lock toolholders accepting DCG-series PCBN turning inserts with ANSI code 2NUDCGA32.51 and ISO code 2NU-DCGW11T304.

Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to seat the screw-lock fastener to toolholder manufacturer specification — do not overtighten. PCBN inserts are brittle; handle with care and avoid contact between cutting edges during storage and installation.\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: BN1000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: 2NUDCGA32.51\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: 2NU-DCGW11T304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (Shape Code D) 55-degree included angle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 2NU-DCGA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DCG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.0984 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0150 inches\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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Hardened Steel, Superalloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw\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: 0.04 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: 161NWCJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51747474768178,"sku":"161NWCJ","price":111.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc7bfed8f76abc4011bf0a1efb9c38f8.jpg?v=1788880963","url":"https:\/\/voomisupply.com\/products\/sumitomo-161nwcj-pcbn-turning-insert-3-8-inch-ic-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
