Manufactured under the ANSI code NUDNMA430 and ISO code NU-DNMA150401, this insert features a 55-degree diamond shape with a negative rake geometry and a relief angle of 0 degrees. The inscribed circle measures 0.5 inches, insert thickness is 0.1875 inches, and the corner radius is 0.0039 inches. It is uncoated and carries the BN2000 manufacturer grade. Licensed machinists and CNC operators install this insert when hard turning hardened steels, cast irons, and other difficult-to-machine materials to achieve tight tolerances and fine surface finishes.\u003c\/p\u003e\u003cp\u003eThis insert is suited for hard turning operations in both production and job-shop environments where conventional carbide tooling is insufficient. The NUDNMA430 style is applied in finish and semi-finish turning of hardened ferrous workpieces, sintered metals, and other hard materials. Its single cutting edge geometry and clamp-plus-pin holding method make it well-suited for rigid setups requiring consistent chip control. The chip breaker designation is A, and the maximum depth of cut is 0.015 inches, confirming its role in light, precision finishing cuts rather than heavy roughing operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePCBN insert material provides extreme hardness for turning hardened and abrasive workpieces\u003c\/li\u003e\n\u003cli\u003eBN2000 uncoated grade optimized for hard material (H) primary workpiece applications\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with negative rake for controlled edge strength\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0039 inches supports fine surface finish on finish turning passes\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.015 inches engineered for precision finishing cuts\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method ensures rigid, repeatable insert seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-format PCBN turning insert conforming to ANSI NUDNMA430 and ISO NU-DNMA150401 specifications, compatible with toolholders designed for the NU-DNMA insert style with a 0.2031-inch hole diameter and clamp-plus-pin retention.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified CNC machinists and tool crib technicians. Power down and lock out the machine spindle before removing or seating the insert. Ensure the toolholder pocket and seating surfaces are clean and free of chips before installing. Follow the toolholder manufacturer torque guidelines for the clamp screw to avoid insert cracking or improper seating.\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\u003eANSI Code\u003c\/strong\u003e: NUDNMA430\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: NU-DNMA150401\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55-degree included angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0039 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.1063 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\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: M\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\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: D\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: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.5 inches\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: 16JRCVC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51738161676594,"sku":"16JRCVC","price":64.08,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d0006e43d1d95cb160233922b60bcdf.jpg?v=1788796521","url":"https:\/\/voomisupply.com\/products\/sumitomo-16jrcvc-pcbn-turning-insert-1-2-inch-ic-bn2000","provider":"Voomi Supply","version":"1.0","type":"link"}
