It carries the BNC200 manufacturer grade and features a Physical Vapor Deposition (PVD) TiN coating applied over the PCBN substrate. The insert is diamond-shaped with an 80-degree included angle, a 0.5-inch inscribed circle, a 0.03125-inch corner radius, and a 0.1875-inch insert thickness. With four usable cutting edges and a negative rake geometry, it is engineered for stable, high-precision turning operations under interrupted and continuous cut conditions. Machinists and CNC operators in production and job-shop environments install this insert into compatible toolholders for hard-turning applications.\u003c\/p\u003e\u003cp\u003eThe 16DTCEB is suited for hard turning of hardened steels and secondary workpiece materials classified under the H material group. It fits into CNGA-style toolholders secured by clamp and pin holding methods. Typical applications include finish and semi-finish turning of bearing surfaces, hardened shafts, and similar components where tight dimensional tolerances and consistent surface finish are required. The ANSI code is 4NCCNGA432 and the ISO code is 4NC-CNGA120408, making it straightforward to cross-reference against existing toolholder specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePCBN insert material provides hardness and wear resistance for machining hardened steel\u003c\/li\u003e\n\u003cli\u003eBNC200 grade with PVD TiN coating for extended tool life and thermal protection\u003c\/li\u003e\n\u003cli\u003e80-degree diamond shape with 0.03125-inch corner radius for precise contouring\u003c\/li\u003e\n\u003cli\u003eFour cutting edges maximize insert utilization and reduce per-edge tooling cost\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry with clamp and pin holding for rigid, vibration-resistant setup\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI and ISO 13399 standards for consistent toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNGA-style toolholders accepting a 4NC insert configuration.

Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before changing inserts. Inspect the toolholder pocket and seating surfaces for chips or debris before seating the insert. Follow the toolholder manufacturer's specifications for clamp and pin hardware torque requirements.\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: BNC200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (PVD Process)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80-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\u003eCorner Radius\u003c\/strong\u003e: 0.03125 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\u003eInsert Length\u003c\/strong\u003e: 0.0945 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: 0.0150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel (H Code)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: 4NCCNGA432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: 4NC-CNGA120408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\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: 16DTCEB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51730932990258,"sku":"16DTCEB","price":173.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f47aff84ae7126c45c765ab6fb8798b6.jpg?v=1788725001","url":"https:\/\/voomisupply.com\/products\/sumitomo-16dtceb-pcbn-turning-insert-bnc200-diamond-80-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
