Built to ANSI code NFCNMX431 and ISO code NF-CNMX120404, this uncoated insert features an 80-degree diamond shape with a 0.5-inch inscribed circle and a 1\/64-inch (0.0156-inch) corner radius. The DA2200 grade PCD substrate delivers exceptional wear resistance and edge retention at elevated cutting speeds. It is installed by CNC machinists and toolroom technicians working on turning centers and lathes equipped with compatible toolholders. The insert mounts via clamp and pin holding method, providing secure seating during interrupted or continuous cuts on aluminum, copper, brass, and composite workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finish and semi-finish turning operations on non-ferrous workpieces in production and job-shop environments. Its chip breaker designation X and clearance code N make it appropriate for applications requiring tight tolerances and consistent surface finish. The NF-CNMX style geometry is commonly used on CNC turning centers where high-volume output and dimensional repeatability are priorities. Typical applications include aluminum automotive components, copper alloy fittings, and composite aerospace blanks where conventional carbide grades wear prematurely.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePolycrystalline Diamond (PCD) insert material for superior wear resistance on non-ferrous and non-metallic workpieces\u003c\/li\u003e\n  \u003cli\u003eDA2200 manufacturer grade with uncoated finish for sharp, low-friction cutting edges\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (Shape Code C) with 0.0156-inch corner radius for precise profiling\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method for rigid, repeatable seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO 13399 standards for insert geometry and dimensional consistency\u003c\/li\u003e\n  \u003cli\u003eSeries C with chip breaker X geometry suited for finish turning at tight tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders accepting NF-CNMX style inserts with a 0.5-inch inscribed circle.

Power down and lock out the turning center before seating or replacing inserts. Use the correct clamp torque per the toolholder manufacturer's specification and ensure the pin locator is fully engaged before tightening. Do not use PCD inserts on ferrous metals, hardened steels, or titanium alloys, as these materials will rapidly degrade the diamond cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Polycrystalline Diamond (PCD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: DA2200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (Shape Code C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\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: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.2244 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\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\u003eInsert Style\u003c\/strong\u003e: NF-CNMX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: NFCNMX431\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: NF-CNMX120404\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\u003eChip Breaker\u003c\/strong\u003e: X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\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\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 16CDBBY\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51741424517426,"sku":"16CDBBY","price":97.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85a76f0c4b868abc7ee91d7b4e86b692.jpg?v=1788831445","url":"https:\/\/voomisupply.com\/products\/sumitomo-16cdbby-pcd-turning-insert-nf-cnmx431","provider":"Voomi Supply","version":"1.0","type":"link"}
