It features a 55-degree included angle, a 0.5-inch inscribed circle, and a 1\/64-inch (0.0156-inch) corner radius. The insert carries a 3\/16-inch thickness and conforms to DNGA style geometry with a G tolerance code and N clearance code. Designed for precision turning operations, it is held in place using a clamp and pin method. Machinists and toolroom operators use this insert in CNC turning centers and manual lathes where hardened ferrous materials and superalloys demand the cutting performance that PCBN tooling provides.\u003c\/p\u003e\u003cp\u003eThis insert is suited for finish and semi-finish turning of hardened steels, cast irons, and other hard-to-machine materials where carbide tooling reaches its performance limits. The DNGA insert style fits standard negative-rake toolholders commonly used in production turning environments. Its uncoated PCBN construction in grade HT630BN makes it appropriate for dry or minimal-lubrication hard-turning applications typical in aerospace, automotive, and precision-machining shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eUncoated Polycrystalline Cubic Boron Nitride (PCBN) construction, grade HT630BN\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape (Shape Code D) for versatile turning geometry\u003c\/li\u003e\n\u003cli\u003e0.5-inch inscribed circle with 3\/16-inch insert thickness\u003c\/li\u003e\n\u003cli\u003e1\/64-inch corner radius (0.0156 inches) for controlled surface finish\u003c\/li\u003e\n\u003cli\u003eG tolerance and N clearance codes for consistent dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method compatible with standard DNGA negative-rake toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement insert for standard DNGA-style negative-rake turning toolholders accepting a 0.5-inch inscribed circle, 55-degree diamond insert.

Power down and lock out the machine spindle before seating or replacing any insert. Use the appropriate torx or hex key to secure the clamp and pin holding mechanism to the toolholder manufacturer's recommended procedure. Inspect the toolholder pocket and seating surface for wear or debris before installing a new insert to ensure proper contact and avoid premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 2SH-DNGA\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\u003eInsert Shape Code\u003c\/strong\u003e: D\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: HT630BN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches \/ 12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 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\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: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches\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\u003eMaterial Grade\u003c\/strong\u003e: C2\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: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.5 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2SHDNGA431630BN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730294014258,"sku":"2SHDNGA431630BN","price":1596.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e75bfb9bb05362a586193de98795d96c.jpg?v=1788714818","url":"https:\/\/voomisupply.com\/products\/hertel-2shdnga431630bn-turning-insert-pcbn-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
