It carries the BNC200 manufacturer grade and a PVD-applied TiN finish that supports cutting edge durability at elevated temperatures. The insert follows the ANSI code 2NCCNGA432 and ISO code 2NC-CNGA120408, with an 80-degree diamond shape, a neutral hand orientation, and a negative rake geometry. With a 0.5-inch inscribed circle and a 1\/32-inch corner radius, it is sized for precision turning operations. Licensed machinists and CNC turning specialists are the typical installers of this insert class.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning operations on cast iron, hardened steel, and superalloys. The 2NC-CNGA insert style with a clamp-and-pin holding method makes it suitable for rigid toolholding setups common in production turning environments, including both conventional and CNC lathes. Its PCBN substrate performs best in interrupted and continuous cuts on hardened workpieces where carbide grades reach their wear limits. It is sold individually and ordered in single-unit multiples.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePCBN substrate rated for cast iron, hardened steel, and superalloy workpieces\u003c\/li\u003e\n  \u003cli\u003eBNC200 grade with PVD TiN coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (Shape Code C) for versatile turning profiles\u003c\/li\u003e\n  \u003cli\u003eNegative rake, neutral hand geometry compatible with 2NC-CNGA toolholders\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO 13399 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to fit toolholders accepting the 2NC-CNGA432 insert style with clamp-and-pin mounting.

Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before seating or replacing inserts. Seat the insert firmly against the pocket locating surfaces and verify the clamp and pin are fully engaged before resuming operation. Do not exceed the maximum depth of cut specified for this insert geometry, as PCBN substrates are sensitive to impact loads beyond their designed parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: 2NCCNGA432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: 2NC-CNGA120408\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: BNC200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees, Shape Code C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 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: 0.0945 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: 2\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\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hardened Steel, Superalloy\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\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: 16DTBKB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51732662124850,"sku":"16DTBKB","price":91.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00cb27662c6577b6b08e5a1c050d4174.jpg?v=1788745466","url":"https:\/\/voomisupply.com\/products\/sumitomo-16dtbkb-pcbn-turning-insert-bnc200-tin-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
